The conventional shorts-type diapers are provided with folds around the legs in order to prevent leakage, but It is difficult for the absorber (absorbent core) to fully adhere to the body, and it is easy to create a gap between the absorber and the body. Therefore, when the released amount of urine or the like exceeds the absorption amount of the absorbent body, or when the urine or the like does not reach the absorbent body, there is a possibility that urine flows from the gap to the abdomen. Urine that is not absorbed by the absorbent body reaches the side folds such as the folds around the legs of the disposable diaper along the body. The side folds are formed of non-woven fabrics, etc., and are not inherently absorbent. Therefore, even if side folds such as folds around the legs are provided, it is difficult to reliably prevent urine from leaking to the outside. In addition, in the conventional disposable diaper, when urine or the like is absorbed, the absorbing part swells, and only this swells up. In this case, since it is clearly seen that the urine has been discharged from the appearance, it is not a situation that the wearer likes. Such undesirable conditions can also occur in the same way for women's menstrual blood. In addition, although conventional diapers are made of air-permeable materials such as non-woven fabrics, they have insufficient air permeability and moisture permeability, and it is difficult to say that the skin feels adequate, and the moisture evaporability is insufficient, and the wearability is not good. .

The present invention is developed in view of the problems of the conventional disposable clothing, and provides a disposable clothing which has excellent air permeability, moisture permeability, evapotranspiration, and conformability, and is not easy to produce even when used as a diaper.

Furthermore, the term "absorption" in this specification is not limited to the absorption of urine and the like, and includes the absorption of all fluids such as menstrual blood and sweat used by women, or the absorption of other excreta.

Fig. 1 is an external view showing a state in which a wearer P wears the disposable clothing 1 according to the first embodiment of the present invention. FIG. 2 is a longitudinal sectional view of the disposable clothing 1.

Furthermore, in this specification, the vertical direction when the wearer P wears the disposable clothing 1 is set as the vertical direction in the description of the disposable clothing 1, and the left-right direction is the horizontal direction of the disposable clothing 1 In addition, the front-back direction of the wearer is described as the front-back direction in the description of the disposable clothing 1.

As shown in FIGS. 1 and 2, the disposable clothing 1 is composed of a waist part 21 worn on the waist of a wearer P and a body part wearing part 20. The body part wearing part 20 has a front part 20a, The rear part 20b and the lower part of the crotch 20c between the front part 20a and the rear part 20b are formed with left and right leg peripheral openings 20f. It is located inside the lower part of the crotch 20c of the body part wearing part 20, and is provided with an elastic sheet 17 spanning between the front part 20a and the rear part 20b, and an absorber 10 is arranged on the inner side (the wearer's side) of the elastic sheet 17 . The openings 20f around the legs of the body part wearing part 20 do not have wrinkles like conventional diapers, but are configured as non-wrinkle parts.

(Lower crotch)

As shown in FIG. 2, the lower part of the crotch 20c may have a connecting portion 20d that can be connected and disconnected. The connecting portion 20d is constituted by a surface fastener, a hook, a button, an adhesive sheet, an adhesive, and the like. For example, when the connecting part 20d is formed by the surface fastener, the wearer can connect the lower part of the crotch 20c by overlapping the connecting surfaces of the surface fastener with each other as shown in FIG. The connecting surfaces of the surface fasteners are separated from each other to open the lower part of the crotch 20c. In addition, the connecting portion 20d may only be configured to be open. For example, the lower crotch 20c is joined by heat fusion, stitching, heat sealing, ultrasonic joining, and the like, and the joint is divided as necessary to open the lower crotch 20c. In addition, it may be configured such that a planned cutting line (suture hole) is added to a portion of the lower crotch 20c, and the planned cutting line is divided as necessary, thereby opening the lower crotch 20c. By opening the lower part of the crotch 20c, the shape of the body part wearing part 20 can be made into a belt type (refer to FIG. 46).

In addition, the lower part of the crotch 20c may be configured to be connected and detachably attached to the front part 20a and the rear part 20b.

(Body wearing part)

As shown in FIG. 1, the body part wearing part 20 has a shape substantially the same as that of shorts as general underwear and sports shorts as clothing, and has the same height. In the trunk wearing part 20, slits 29 are provided on both sides. By providing the slit 29, the wearer P can easily move his legs. In addition, the body part wearing part 20 is not limited to the example of the present embodiment, and may have a shape that covers the upper part of the wearer P's waist. In addition, the body part wearing part 20 may cover the lower part of the hip bone. Also, for women, the sides are cut into a shape shorter than that in Fig. 1 (ie, a substantially V-shaped shape when viewed from the front), thereby making it easier to move the legs.

In the body part wearing part 20, the front part 20a and the back part 20b may be the same size or different. By making the rear part 20b of the body part wearing part 20 larger than the front part 20a, it is possible to provide a disposable garment 1 that is easy to wear by a wearer with a large buttocks. In addition, when the size of the front part 20a and the rear part 20b are different, since they can be sewn three-dimensionally, it is possible to provide disposable clothing 1 that is more suitable for wearers of various body types.

(Stretchable composite sheet)

In the disposable clothing 1, at least the body part wearing part 20 is composed of a stretchable composite sheet as shown in FIG. A layered liquid diffusing fiber sheet 201 and a linear elastic body 202 are arranged in between, and it has a pressure force applied to the crotch of the wearer, especially the upper crotch area 20e from the lower part of the crotch 20c to the upper side and the periphery of the leg. Scalability. Preferably, in the stretchable composite sheet, the portion where the linear elastic body 202 is arranged has an extensibility of 1.2 to 5.0 times in the stretch direction of the linear elastic body 202.

(Waist)

The waist part 21 is a part worn on the waist of the wearer P, and is arranged on the upper part of the body part wearing part 20, and a waist opening 21a is formed on the upper end side. The waist portion 21 is preferably composed of a material having elasticity, and is composed of a stretchable composite sheet integrally with the body part wearing part 20, but it may be formed of a material different from the body part wearing part 20. Formed separately. The waist portion 21 is stretchable in the waist direction, which can improve the conformability of the disposable clothing 1 to the wearer, so Better. The waist part 21 may have a folded-back part 21c formed by folding the waist opening 21a side inwardly (refer to FIGS. 1 and 26H).

(Breathable sheet)

Examples of the air-permeable sheets 203 and 205 constituting the stretchable composite sheet include non-woven fabrics, porous sheets, laminates of these, and the like. As the non-woven fabric, spun-bonded non-woven fabric, thermal-bonded non-woven fabric, spunlace non-woven fabric, dry non-woven fabric, wet non-woven fabric, melt-blown non-woven fabric, chemically bonded non-woven fabric, needle-punched non-woven fabric, stitch-bonded non-woven fabric, steam jet non-woven fabric, etc. are preferably used. Best for spunbonded nonwovens, thermally bonded nonwovens, and spunlaced nonwovens. Examples of fibers constituting the nonwoven fabric include natural fibers such as animal fibers, synthetic fibers such as nylon, acrylic, polyolefin, and polyethylene terephthalate, and regenerated fibers such as rayon. However, synthetic fibers and regenerated fibers are preferred. On the other hand, as a porous sheet, a synthetic resin film, such as polyethylene, provided with many fine holes, etc. are mentioned. The air-permeable sheets 203 and 205 are preferably sheets with a weight per unit area (weight per unit area) of 5-40 g/m ² . The air-permeable sheets 203 and 205 may use sheets of the same material and weight per unit area, or sheets of different materials and weight per unit area. The material of the air-permeable sheets 203 and 205 can be appropriately selected according to the positions where they are arranged. For example, the air-permeable sheet provided on the outer side of the clothing 1 is preferably one having high water permeability resistance, and is preferably a non-woven fabric or porous sheet that has been subjected to water repellent treatment or the like. In addition, the air-permeable sheet provided on the skin side is the same as the air-permeable sheet provided on the outer surface side, and may be one with higher water permeability resistance, or a sheet with better moisture permeability and water permeability may be used. As an air-permeable sheet, a non-woven fabric is particularly preferred because it is excellent in air permeability and moisture permeability, and can improve water permeability resistance by water-repellent treatment.

(Liquid diffusing fiber sheet)

As the liquid diffusing fibrous sheet 201, a paper-making sheet containing natural fibers such as pulp can be cited. The liquid diffusing fibrous sheet 201 preferably has a pulp blending ratio of 30% or more, and more preferably a pulp blending ratio of 50% or more. Furthermore, the blending of pulp is more preferably 80% or more. By blending the pulp in the above-mentioned ratio, the flexibility of the entire stretchable composite sheet can be improved, or the production efficiency at the time of manufacturing can be improved. In addition, by improving the blending of pulp, the waste can be easily decomposed in, for example, soil after it is discarded. Therefore, the environmental load can be further reduced, and environmental considerations can be improved. As the liquid diffusing fibrous sheet 201, a paper sheet made of a slurry containing fibers such as pulp is preferable, and a paper sheet is more preferable. When a paper sheet is used as the liquid diffusing fibrous sheet 201, at least one of water repellent processing, water repellent processing, water repellent processing, and water resistant processing may also be performed. Furthermore, the liquid diffusing fiber sheet 201 is preferably composed of a single layer, but may be composed of multiple layers. When the liquid diffusing paper sheet 201 is composed of a plurality of fiber sheets, the thickness, material, etc. of the fiber sheets may be the same, or two or more different materials may be used in combination. The liquid diffusing fiber sheet 201 preferably has a weight per unit area of 5-40 g/m ² .

The liquid diffusing fiber sheet 201 can be set to a desired hardness according to thickness, material, and the like. Therefore, by using a method such as locally changing the thickness of the liquid diffusing fiber sheet 201, a three-dimensionally designed disposable garment 1 can be produced. With this method, for example, it is also possible to modify the design of disposable clothing 1 in the manner of underwear. In this case, it is possible to provide the disposable clothing 1 which makes the body line difficult to be eye-catching, or can make the body line appear more beautifully. In addition, by locally hardening the liquid diffusing fibrous sheet 201 at the end of the body part wearing part 20, the disposable clothes 1 can have the same texture as normal clothes and the like. In addition, by locally increasing the thickness of the liquid diffusing fibrous sheet 201 and hardening the portion, the liquid diffusing fibrous sheet 201 can be prevented from being loosened locally. As a result, in the hardened part, more is formed between the liquid diffusing fibrous sheet 201 and the body. Therefore, the air permeability can be improved. On the other hand, by making the thickness of the liquid diffusing fiber sheet 201 thinner, the liquid diffusing fiber sheet 201 is easily loosened, so that the disposable garment 1 can be made soft as a whole or partially.

(pulp)

Examples of the pulp used for the liquid diffusing fiber sheet 201 include wood pulp, synthetic pulp, and waste paper pulp. In addition, it is not limited to those composed of natural fibers such as pulp, and recycled fibers such as rayon may be included. Furthermore, as a raw material pulp, a toilet paper material can also be used. In this case, for example, bleached kraft pulp of conifers obtained from conifers such as red pine, cedar, white fir, yellow cedar, hemlock, and spruce, and bleached kraft pulp from beech, oak, birch, eucalyptus, beam tree, etc. can also be used. The bleached kraft pulp of broad-leaved trees obtained from broad-leaved trees such as poplar and alder is a raw material pulp that is formulated in a predetermined ratio. The liquid diffusing fiber sheet 201 is preferably composed of only natural fibers. As natural fibers other than pulp, for example, kenaf, bamboo fiber, straw, cotton, cocoon silk, sugar cane, etc. can be used. When a paper sheet is used as the liquid diffusing fibrous sheet 201, the paper sheet may have hydrolyzability or non-hydrolyzable, but it is preferably hydrolyzable. The fibers used for the liquid diffusing fiber sheet 201 may also be short fibers, long fibers, or a combination thereof.

(Softener)

In addition, by making the liquid diffusing fiber sheet 201 contain a softening agent, the stretchability can be improved. For example, when a liquid-diffusing fiber sheet is not included between air-permeable sheets such as non-woven fabrics, and a laminated structure of elastomer is arranged, although it has stretchability, air permeability, moisture permeability, flexibility, and transpiration are insufficient. On the other hand, when a stretchable composite sheet composed of a layered liquid diffusing fiber sheet and an elastomer is arranged between the breathable sheets, the moisture absorption, air permeability, moisture permeability, Improved flexibility and evapotranspiration. Furthermore, when the liquid diffusing fibrous sheet 201 contains a softener, the flexibility is further improved, of course, the absorbency and moisture permeability are also improved, and the stretchability can be improved.

(Linear elastomer)

The linear elastic body 202 is provided to make the body part wearing part 20 have stretchability that imparts pressing force to the wearer P. The linear elastic body 202 is preferably arranged on the entire stretchable composite sheet, if it is placed on the lower part of the crotch 20c. When the linear elastic body 202 is arranged, when the wearer wears it, the openings 20f around the legs extend in the width direction, and the lower part of the crotch extends in the width direction. The linear elastic body 202 is a member made up of elastic materials such as elastic body and rubber in a linear shape. Examples of elastomers include styrene-based elastomers, olefin-based elastomers, urethane-based elastomers, polyester-based elastomers, butadiene-based elastomers, vinyl chloride-based elastomers, and silicone-based elastomers. Elastomers, etc. In addition, examples of rubber include natural rubber, styrene-butadiene rubber, butadiene rubber, chloroprene rubber, isoprene rubber, silicone rubber, fluororubber, acrylic rubber, urethane Ester rubber, etc. The linear elastic body 202 in the lower part of the crotch 20c is preferably arranged in a plurality of pieces from the opening 20f around one leg of the lower part of the crotch 20c toward the opening 20f around the other leg, or arranged in the front part 20a of the body wearing part 20 and The connection direction of the rear part 20b. The linear elastic body 202 is preferably arranged in a plurality of pieces at an interval of 2.00 mm to 7.00 mm, more preferably 3.00 mm to 6.25 mm. If the linear elastic body 202 is arranged at an interval of 3.00mm~6.25mm, as shown in Figure 62A, a neat texture and finer wrinkles are formed and the thickness is also fixed, the appearance is good, the skin feels better, and the surface area becomes larger. Therefore, the absorption and evapotranspiration of sweat, etc. are improved. On the other hand, when the interval between the linear elastic bodies 202 exceeds 6.25 mm, as shown in FIG. 62B, serpentine wrinkles are formed, or thickness unevenness occurs. The linear elastic body 202 is preferably arranged in the liquid The position where the body diffusible fiber sheet 201 touches. The strength and material of the linear elastic body 202 are appropriately selected according to the position of the arrangement. For example, the front part 20a and the rear part 20b of the trunk|drum wearing part 20 may be arrange|positioned as the pressing member 202 of different strength and material, respectively. In the front part 20a and the rear part 20b of the trunk wearing part 20, if the strength and material of the linear elastic body 202 are the same, the shape of the trunk wearing part 20 is easily restricted. However, by arranging the front part 20a and the back part 20b of the body part wearing part 20 to be linear elastic bodies 202 of different strength and material, the degree of freedom of shape can be improved. Therefore, for example, the body part wearing part 20 can be made into a three-dimensional shape.

(Joining method of stretchable composite sheet)

The air-permeable sheets 203, 205, the liquid diffusing fiber sheet 201, and the linear elastic body 202 in the stretchable composite sheet can be laminated and integrated by bonding, heat melting, ultrasonic bonding, etc., but it is preferably by From then on, layer-by-layer integration. Examples of the adhesive include latex adhesives, pressure-sensitive adhesives, hot melt adhesives, etc., but hot melt adhesives are preferred. When the air-permeable sheets 203, 205, the liquid-diffusing fiber sheet 201, and the linear elastic body 202 are laminated and integrated, the air-permeable sheets 203, 205 and the liquid-diffusing fiber sheet 201 can be combined with an adhesive. The entire surface of the same can be applied without gaps and then adhered, or a non-joining portion where the adhesive is not partially applied and adhered may be provided. As shown in FIG. 4, an adhesive 218 is applied to the surface of the linear elastic body 202, and the air-permeable sheet 203 and the liquid diffusing fibrous sheet 201 are bonded into stripes by the adhesive through the linear elastic body 202. , Grid-like, dot-like, etc., thereby forming a joint portion where the air-permeable sheet 203 and the liquid diffusing fiber sheet 201 are joined by the adhesive 218, and a non-joining portion 219 that is not joined. In addition, when the air-permeable sheet 205 and the liquid-diffusing fiber sheet 201 are bonded, the adhesive is applied in stripes, grids, dots, etc., to bond the air-permeable sheet 205 and the liquid-diffusing fiber sheet 201. Between the fiber sheets 201, a joined part and a non-joined part are formed. If the air permeable fiber sheet 205 and the liquid diffusing fiber sheet 201 The non-joint part is formed between the air-permeable sheet 203 and the liquid-diffusing fibrous sheet 201, the air permeability and moisture permeability of the stretchable composite sheet can be improved, and the softness or skin touch can also be improved. improve. Hot melt adhesives have high water repellency. Therefore, if the hot melt adhesives are applied to the entire surface of the air-permeable sheets 203, 205, the liquid-diffusing fiber sheet 201, etc. without any gaps, then there will be air permeability and moisture permeability. There is a risk of decreased performance and flexibility, but by intermittently applying hot melt adhesive to provide non-joining parts, excellent air permeability, moisture permeability, and flexibility can be maintained. In addition, since the amount of adhesive used can be reduced, cost reduction can be achieved, and when the disposable clothing 1 after use is discarded, the impact on the environment can be reduced.

(Adhesive)

The adhesive used for bonding is not particularly limited, and it is preferable to use well-known adhesives, for example, EVA (ethylene-vinyl acetate copolymer) series, PO (polyolefin) series, PA (polyamide) series , SR (synthetic rubber) type, ACR (acrylic) type, PUR (polyurethane, moisture curing type) type, etc. These may be used individually by 1 type, and may use 2 or more types together. Furthermore, in addition to the above, other substances may be used in combination. Since the hot melt adhesive has high permeability to the liquid diffusible fibrous sheet 201, the adhesive easily penetrates into the liquid diffusible fibrous sheet 201. As shown in FIG. 4, a part of the adhesive 218 penetrates into the liquid diffusive The gaps between the fibers of the fiber sheet 201 form a fixed portion 201a in which the adhesive and the fibers are integrated. FIG. 4 shows a state where the air-permeable sheet 203 and the liquid diffusing fiber sheet 201 are bonded via the pressing member 202 coated with the adhesive 218 on the surface. The air-permeable sheet 203 is a non-woven fabric or porous sheet. Since the liquid diffusivity is lower than that of the liquid-diffusing fibrous sheet 201 such as a paper sheet, it penetrates into the fixed portion 218b of the air-permeable sheet 203 and by penetration The fixing portion 218a formed by the adhesive to the liquid diffusing fiber sheet 201 is smaller than that. If the fixing portions 218a, 218b are formed, then The strength is improved, and the overall strength of the stretchable composite sheet is improved. The fixing portion 218b may not necessarily be formed in the air-permeable sheet 203. When the air-permeable sheet 203, the linear elastic body 202, and the liquid diffusing fibrous sheet 201 are integrated together via the adhesive 218 applied on the surface of the linear elastic body 202, it is preferably liquid diffusing The fiber sheet 201 forms a fixed portion 218a. The liquid-diffusing fiber sheet 201 forms a fixed portion 218a permeated with an adhesive 218 applied to the surface of the linear elastic body 202, and the linear elastic body 202 is air-permeable The sheet 203 and the liquid diffusing fibrous sheet 201 are firmly and firmly sandwiched and held. In addition, the strength of the liquid diffusing fibrous sheet 201 can also be improved. In the case of disposing the linear elastic body 202 between the air-permeable sheets 203 and 205 without using the liquid diffusing fiber sheet 201, a large amount of the adhesive 218 must be applied in order to obtain an appropriate adhesive force. When a large amount of adhesive is applied, not only the elasticity of the linear elastic body 202 is lost, but also the flexibility of the body part wearing part 20 is also reduced, so the skin feel is reduced. In addition, there is a possibility that the adhesive agent oozes out of the air-permeable sheet arranged on the body side and the appearance is deteriorated. In contrast, when the liquid diffusing fiber sheet 201 is further arranged between the air-permeable sheets 203 and 205, and the linear elastic body 202 is arranged in contact with the liquid diffusing fiber sheet 201, then The affinity of the agent 218 to the liquid diffusing sheet 201 is higher than that of the air-permeable sheets 203 and 205, and the retention force of the linear elastomer 202 of the liquid diffusing fibrous sheet 201 is higher than that of the air-permeable sheet 203, The retaining force of the linear elastic body 202 of 205 is higher, so the linear elastic body 202 is reliably held in the composite sheet, especially the adhesive 218 coated on the surface of the linear elastic body 202 penetrates into the liquid diffusing fiber sheet The fixed portion 218a integrated with the fiber is formed in the material 201, whereby a smaller amount of hot melt adhesive can be used to obtain a strong adhesive force. Thereby, since a large amount of hot melt adhesive is not used, the elastic force of the pressing member 202 is not lost, and the holding force in the stretchable composite sheet of the linear elastic body 202 is further improved. In addition, the flexibility of the body wearing part 20 is increased, and the hot melt adhesive It does not ooze out from the non-woven fabric 203 arranged on the body side, so the skin feels good, and the appearance can also be improved. In addition, when the stretchable composite sheet is cut, the linear elastic body 202 is surely held in the cut end portion. Therefore, there is no risk of the non-existent portion of the linear elastic body 202 caused by the subsequent deviation of the linear elastic body 202 in the cut end portion and the end of the linear elastic body 202 is introduced into the sheet. In addition, since the liquid diffusing fiber sheet 201 forms the fixing portion 218a, even when the liquid diffusing fiber sheet 201 composed of a paper sheet or the like is exposed to water, the liquid diffusing fiber sheet can be difficult to make 201 destruction. In addition, since the amount of hot melt adhesive used can be reduced, the cost can be reduced. In addition, since the amount of hot melt adhesive used can be reduced, when the disposable clothes 1 after use are discarded, the impact on the environment can be reduced. In addition, since the amount of hot melt adhesive used can be reduced, the air permeability of the body part 20 and the evapotranspiration of sweat and the like can also be improved.

(Embossing treatment)

It is preferable to perform an embossing process on the liquid diffusing fibrous sheet 201. FIG. 5 shows an example of the liquid diffusing fiber sheet 201 in which the concave and convex portions 213 composed of the concave portions 211 and the convex portions 212 are formed by embossing. The concave portion 211 and the convex portion 212 can be formed on the entire surface of the liquid diffusing fiber sheet 201 by embossing with an embossing roller, for example. The embossing process can be implemented by pressing the liquid diffusing fiber sheet against an embossing roller by one of a plurality of protrusions provided on the peripheral surface, for example. In addition, the cross-sectional shape of the embossed concave and convex portion 213 is not limited to the waveform shown in FIG. Since the surface of the liquid diffusing fiber sheet 201 is formed with the uneven portions 213, the liquid diffusing fiber sheet 201 can be made into a bulky state. However, the method of forming the uneven portion 213 on the surface of the liquid diffusing fibrous sheet 201 is not limited to the embossing process of the embossing roll, and other methods may be used to form it.

The concave-convex portion 213 formed by the embossing process is not limited to the concave-convex shape as shown in FIG. That is, the uneven portion is not limited to the uneven portion 213 as an example, and various shapes that function equally can be applied. Furthermore, a flat part may be partly included, and what is necessary is just to be a non-flat part as a whole. By subjecting the liquid diffusing fibrous sheet 201 to an embossing process, the strength is lowered compared with the case where the embossing process is not applied, and fragile portions are generated. Furthermore, the embossing process is not limited to the case where the uneven portions 213 are formed on the surface of the liquid diffusing fiber sheet 201, and it can be performed by pressing the liquid diffusing fiber sheet 201 with a flat roller having no protrusions on the peripheral surface. It can also be performed by combining a pair of embossing rollers provided with a plurality of protrusions on the peripheral surface and a flat roller without protrusions on the peripheral surface. In addition, it is not limited to one treatment, and multiple treatments may be performed.

Fig. 6 shows an example in which air-permeable sheets 203 and 205 are laminated to a liquid-diffusing fibrous sheet 201 that has been embossed to form a laminate. As shown in FIG. 6, the air A1 passes through the inside of the air-permeable sheet 205 as shown in the flow of air. In the second pattern, air A2 alternately passes between the air-permeable sheet 203, the liquid-diffusing fiber sheet 201, and the air-permeable sheet 205. Furthermore, the paste 214 adhering between the liquid diffusing fiber sheet 201 and the air-permeable sheet 205 may be partially applied between the liquid diffusing fiber sheet 201 and the air-permeable sheet 205. Therefore, the air A2 between the liquid diffusing fiber sheet 201 and the air-permeable sheet 205 can pass through the space where the paste 214 is not applied. In the third pattern, air A3 passes through the air-permeable sheet 203, the liquid-diffusing fiber sheet 201, and the air-permeable sheet 205 in this order. Furthermore, in the third pattern, air A3 may pass through the air-permeable sheet 205, the liquid-diffusing fiber sheet 201, and the air-permeable sheet 203 in this order as shown by the broken line in the figure. Furthermore, the form of air passage is not limited to the above three patterns, and various forms can be considered. For example, the air can also pass through the concave-convex part 213.

The embossing process is not limited to the case where the embossing process is performed only on the liquid diffusing fibrous sheet 201, and a part of the air-permeable sheets 203, 205 and fibrous elastomer 202 may be laminated on the liquid diffusing fibrous sheet 201. After the fiber sheet 201, or after laminating all of them, embossing is performed and implemented. Figures 7 and 8 show an example of a method of manufacturing a stretchable composite sheet, and Figure 7 shows an air-permeable sheet 203, a liquid-diffusing fibrous sheet 201, an air-permeable sheet 205, and a linear shape not shown. After the elastic body 202 is formed into a laminate in an extended state, a composite sheet is obtained by embossing between a pair of embossing rollers 301 and 302. After passing through the embossing rollers 301 and 302, the tension of the linear elastic body 202 is released. In this way, the stretchable composite sheet 200 in which the wrinkles 213a constituted by the concavo-convex portions 213 are formed is obtained. Fig. 8 shows that the liquid diffusing fibrous sheet 201 is embossed between the embossing rollers 301 and 302 with one of the protrusions on the peripheral surface, and then the air-permeable sheets 203, 205 and the adhesive coated The linear elastic body 202 (not shown) is overlapped in a stretched state, and then laminated and integrated between a pair of flat rollers 303 and 304 to obtain a composite sheet. After passing through the flat rollers 303 and 304, the linear elastic body 202 is released The tensile force thereby obtains the stretchable composite sheet 200 in which the wrinkles 213a constituted by the concave and convex portions 213 are formed. It is believed that the wrinkles 213a in the composite sheet 200 are easily formed by forming a fragile portion on the liquid diffusing fibrous sheet 201 by embossing, and releasing the tension of the linear elastic body 202 by the linear elastic body 202 Formed by the power of restoring to the original state. In addition, if a fragile portion is formed in the liquid diffusing fiber sheet 201, the elastic force of the linear elastic body 202 is not easily damaged, so the wrinkles 213a can be easily formed from the fragile portion as a starting point. The pleats 213a are formed in a plurality along the expansion and contraction direction of the linear elastic body 202. The wrinkles 213a may be partially formed in the composite sheet, but are more preferably formed integrally. The body part wearing part 20 composed of the stretchable composite sheet 200 having such thin wrinkles 213a has a smaller contact area on the surface, so that the skin feels better. In addition, by generating finer wrinkles 213a, the light absorption is improved, And it is not easy to penetrate, making the line of the wearer's body inconspicuous. If a plurality of such wrinkles 213a are formed, a large number of gaps are formed inside the stretchable composite sheet, and the body part wearing part 20 is constituted by the stretchable composite sheet 200 having such a plurality of wrinkles 213a. Thereby, the air permeability of the body part wearing part 20 can be further improved. The number of continuous concavo-convex portions 213 formed on the liquid diffusing fiber sheet 201 is preferably about 15-50 per cm, for example.

Since the stretchable composite sheet 200 has a configuration in which the liquid diffusing fiber sheet 201 is interposed between the air-permeable sheets 203 and 205, it is originally excellent in air permeability. The non-joined portion 219 formed by the partial application of the adhesive used for the laminated integration of the shaped elastic body 202 facilitates the flow of air in the non-joined portion 219, and therefore the air permeability is further improved. Furthermore, due to the presence of the uneven portions 213 of the liquid diffusing fiber sheet 201 or the fine wrinkles 213a on the surface of the stretchable composite sheet 200, air easily circulates through the gaps of the uneven portions 213 or the wrinkles 213a. Therefore, the air permeability can be further improved. If the stretchable composite sheet 200 has fine wrinkles 213a formed on the surface, the contact area with the skin is reduced, so the touch of the skin is improved, and the surface area of the stretchable composite sheet 200 is increased, resulting in the absorption of urine, etc. Improved performance and evapotranspiration. In addition, since the surface of the stretchable composite sheet 200 has fine wrinkles 213a, it has the effect of not being easily penetrated.

By using an embossing roll or the like for the liquid diffusible fiber sheet 201, punching, perforation, and other hole forming processes are performed, and holes, cracks, cuts, etc. of appropriate size can be formed on the surface of the liquid diffusible fiber sheet 201. This treatment may be performed on the liquid diffusing fibrous sheet 201 alone or on the entire stretchable composite sheet. If the liquid diffusing fibrous sheet 201 is subjected to hole forming processing or the above-mentioned embossing processing, the body part wearing part 20 can be made more flexible, soft and excellent in touch.

The disposable clothing 1 is shown as an example in FIG. 1, and printing may be performed on the waist part 21 or the body part wearing part 20. The liquid-diffusing fibrous sheet 201 composed of paper sheets, etc., can print brighter patterns than the air-permeable sheets 203, 205 composed of non-woven fabrics, etc., so when printing is performed, as shown in Figure 3 It is preferable to form a printing layer 201a on the surface of the liquid diffusing fiber sheet 201, and it is possible to print beautiful colors, patterns, photos, etc. (hereinafter, also referred to as "photos, etc.") on the surface of the disposable clothes 1, so that The wearer P's resistance to wearing disposable clothing 1 is even lower.

The printed layer 201a can be formed by inkjet printing or the like, for example. Preferably, the surface of the printed layer 201a is subjected to a color-fading prevention treatment by, for example, varnishing or adding an adhesive. Examples of the adhesive include known materials such as PVA, CMC, EVA, acrylic, and lacquer. In addition, inks with anti-fading treatment can also be used.

Furthermore, when the thickness of the liquid diffusing fiber sheet 201 is thin, it is preferable to form the printing layer 201a by flexographic printing. Since the contact surface between the plate and the liquid diffusing fibrous sheet 201 is a platen, the flexographic printing has the characteristics of fewer contact surfaces and lower printing pressure. Therefore, it is easy to separate the liquid diffusing fiber sheet 201 from the plate, and it is suitable for forming the printing layer 201a on the thin liquid diffusing fiber sheet 201.

In addition, in flexographic printing, there are many types of inks that can be used. Therefore, for example, such as inkjet printing in which the ink is ejected through a nozzle or the like, the viscosity of the ink is less restricted. Therefore, when the printing layer 201a is formed by flexographic printing, the degree of freedom of printable patterns can be improved. Moreover, when the pattern is printed on the printing layer 201a, the pattern printed by the plate is stretched in the direction of expansion and contraction of the linear elastic body 202, and the wearer wears the disposable clothing 1 to appear on the surface The pattern of the desired shape. Specifically, to avoid making linear bullets Under the condition that the elastic body 202 is stretched, when the size of the finished pattern is set to 100%, it is better to form the pattern so that the ratio of the pattern of the printing plate to the stretch direction of the linear elastic body 202 becomes 110~350% . Thereby, when the wearer wears the disposable clothing 1, the pattern will not be unnaturally enlarged, so it becomes a product with better appearance.

Furthermore, when the printing layer 201a is formed on the liquid diffusing fiber sheet 201, the printing layer 201a can be formed either before the liquid diffusing fiber sheet 201 before the embossing process, or after the embossing process is applied. . By using embossing processing, a plurality of concave and convex shapes are formed on the surface of the liquid diffusing fiber sheet 201, which is a three-dimensional design that cannot be expressed in normal printing, and a design with subtle differences according to the viewing angle The performance of waiting becomes possible.

3A to 3D are diagrams showing changes in the body part wearing part 20.

In FIG. 3A, an air-permeable sheet 205 is arranged on the outer side of the liquid-diffusing fiber sheet 201, and a printing layer 201 a is provided between the liquid-diffusing fiber sheet 201 and the air-permeable sheet 205.

In FIG. 3B, an air-permeable sheet 206 is further arranged between the liquid diffusing fiber 201 and the linear elastic body 202.

In FIG. 3C, an air-permeable sheet 207 is further arranged between the liquid-diffusing fiber sheet 201 and the air-permeable sheet 206.

In the above-mentioned configuration of FIGS. 3A to 3C, in the liquid diffusing fiber sheet 201, the air-permeable sheet 205 is arranged on the outer side of the printed layer 201a, so it can reduce the peeling of the photograph of the printed layer 201a due to friction. , Or the bad condition of fading.

In FIG. 3D, a printed layer 201a is formed on the surface of the air-permeable sheet 205. As shown in FIG. according to In this configuration, since the photographs and the like formed on the printed layer 201a rise and are observable, the wearer and the like can observe sharper photographs and the like compared with the case of the non-liquid diffusing fibrous sheet 201.

Since the hot melt adhesive is light-transmissive, by coating on the surface of the printing layer 201a, even if it is wetted by water, the photograph of the printing layer 201a will not be blurred or oozing out. Therefore, the ink used as the printing layer 201a can be either water-based or oil-based, and various inks can be used. In addition, it is possible to reduce defects such as peeling or color fading of the printed layer 201a due to friction.

Although not shown in particular in the stretchable composite sheet, an absorbent polymer layer may be provided. In addition, a water-repellent agent may be applied to the surface of the air-permeable sheet 205 arranged on the outermost side. As the water repellent, oily, silicon-based, Teflon-based, etc. can be used. In this way, by coating the surface of the outermost air-permeable sheet 205 with a water-repellent agent, the penetration of moisture from the outside can be more effectively suppressed.

As the absorbent polymer, a super absorbent polymer material such as sodium polyacrylate is used. The absorbent polymer can be held as a water-absorbent polymer layer in the state of particles or powder between the liquid-diffusing fiber sheet 201 and the air-permeable sheet 203, for example. In this case, urine etc. can be absorbed by the The polymer layer absorbs quickly. In addition, the liquid-diffusing fiber sheet 201 and the air-permeable sheet 205 are arranged on the outer side of the absorbent polymer layer, so that the leakage of urine or the like to the outside can be more effectively suppressed. In addition, since the air-permeable sheet 203 is arranged on the most body side, the skin feel and air permeability are excellent. On the other hand, when the water-absorbent polymer layer is provided on the air-permeable sheet 205 side of the liquid-diffusing fiber sheet 201, most of urine and the like can be absorbed by the liquid-diffusing fiber sheet 201. Therefore, the amount of water-absorbent polymer used can be reduced.

It is also possible to form a plurality of fine holes on the surface of the air-permeable sheet 205 arranged on the outermost side. By providing such holes, the air permeability can be further improved. For example, the holes may be regularly formed in dots or randomly. Moreover, the hole can be formed in the entire air-permeable sheet 205 This surface can also be formed locally.

(Non-hydrophilic sheet)

The stretchable composite sheet 200 may be further provided with a non-hydrophilic sheet 209 as shown in FIGS. 9A and 9B. The stretchable composite sheet 200 shown in FIG. 9A is between the second air-permeable sheet 205 and the liquid diffusing fiber sheet 201, and a hydrophobic sheet 209 as a non-hydrophilic sheet is arranged. As the hydrophobic sheet 209, a moisture-permeable film having the characteristic of allowing air to pass but not allowing moisture to pass is preferable. In the case where the printed layer 201a is formed on the surface of the second air-permeable sheet 205 side of the liquid diffusing fiber sheet 201, the hydrophobic sheet 209 is preferably transparent in order to improve the visibility of the printed layer 201a. High moisture permeability film. In this case, the fine photographs etc. formed on the printing layer 201a can be observed more clearly. In addition, the hydrophobic sheet 209 is not limited to one having high transparency, and may be translucent, for example.

The stretchable composite sheet 200 shown in FIG. 9B has a hydrophobic sheet 209 arranged between the second air permeable sheet 205 and the liquid diffusing fiber sheet 201, and the air permeable sheet 205 of the hydrophobic sheet 209 A printing layer 201a is formed on the surface of the side. In the example shown in FIG. 9B, the linear elastic body 202 is arranged between the liquid diffusing fibrous sheet 201 and the first air-permeable sheet 203, but the linear elastic body 202 may also be arranged on the liquid diffusing fibrous sheet 201 and the hydrophobic sheet 209.

Furthermore, when the printed layer 201a is formed on the liquid diffusing fiber sheet 201 or the hydrophobic sheet 209, in order to improve the visibility of the printed layer 201a, it is preferable that the linear elastic body 202 is not arranged on the larger printed layer 201a is closer to the air-permeable sheet 205 side. In addition, the hydrophobic sheet is not limited to a non-hydrophilic one, and may be a water-repellent one.

Furthermore, in the above example, the case where the hydrophobic sheet 209 is provided is shown, but Instead of the hydrophobic sheet, a hydrophilic sheet may be provided, and it is more preferable to provide a hydrophilic sheet.

Fig. 10 shows a change in the arrangement of the linear elastic body. As shown in Figs. 10A to 10C, the linear elastic body 202 may be arranged linearly, as shown in Fig. 10D, or arranged in a curved shape. In addition, as the shape of the curve, as shown in FIG. 10E, it may be a waveform. Furthermore, as shown in FIG. 10F, the linear elastic body 202 may be arranged as a line partially including a straight line or a curved line. Furthermore, as shown in FIG. 10G, not only the linear elastic body 202 arranged in the width direction but also the linear elastic body 202 arranged in the perpendicular direction is provided, and the linear elastic body 202 may be lattice-shaped. Moreover, as shown in FIG. 10H, the linear elastic body 202 in a lattice shape may be arranged obliquely. The linear elastic body 202 may be continuous throughout the entire stretchable composite sheet 200 (for example, FIG. 10A, etc.), or may be discontinuous (for example, FIG. 10B, etc.).

The disposable clothing 1 of the present invention uses the stretchable composite sheet 200 in which the linear elastic body 202 is locally arranged, so that the part or the size of the pressing force applied to the wearer's body can be changed. FIG. 11A shows an example of arrangement in which the linear elastic body 202 is located on both sides of the front and/or rear of the disposable garment 1, and FIG. 11B shows the linear elastic body 202 is located in the center of the front and/or rear. Fig. 11C shows an example of arrangement in which the linear elastic body 202 is located between the two sides of the front and/or rear part and the central part. Fig. 11D shows the linear elastic body 202 in the middle of the central part. An example of arrangement in which the upper side parts of the front and/or rear part and the central part are arranged, and the linear elastic body 202 is arranged at the lower part of the crotch of the front part and/or the rear part. Fig. 11E shows a linear arrangement An example of arrangement in which the elastic body 202 is located on both sides of the upper part of the front and/or the rear and on both sides of the lower part of the crotch 20c of the front and/or the rear. In addition, FIG. 11F shows an example of arranging the linear elastic body 202 at the lower sides of the front part and/or the rear part. Arranging linear bullets obliquely An example of the sexual body 202, Fig. 11H shows an example in which the linear elastic body 202 is arranged obliquely to the left and right above the central part of the front and/or rear part, and Fig. 11I shows the crotch at the front part and/or the rear part. An example in which the linear elastic body 202 is arranged obliquely so that the lower part is the center left and right and the center part is the left and right sides. When the linear elastic body 202 is arranged obliquely on the left and right, it may be in the same direction or in different directions in each part. In addition, the patterns shown in FIGS. 11A to 11I may also be combined and arranged in a manner different from the front side and the back side of the disposable garment 1, for example.

In the disposable clothing 1 of the present invention, it is preferable that the body part wearing part 20 is a linear elastic body 202 arranged on the whole. Among them, as shown in FIG. 10A, if a stretchable composite sheet 200 in which a plurality of continuous linear elastic bodies 202 are arranged at predetermined intervals is used, and the stretch direction of the linear elastic bodies 202 becomes the waist circumference direction, then discard The clothing 1 has good conformability to the body, and the production of the stretchable composite sheet is also easy, so it is preferable. When the urine absorber is installed and used as a diaper, it is necessary to increase the width of the waist section 21 to securely fasten it to the wearer’s waist in order to prevent the absorber from slipping even when the weight of the absorber is increased by absorbing urine. However, in the disposable clothing 1 of the present invention, not only the elastic force of the waist part 21 is used to conform to the body, and the linear elastic body 202 is arranged on the entire body wearing part 20, so that the disposable clothing 1 has an impact on the body. The fit is improved, so the height can be designed to be the same as that of ordinary underwear at the hip bone position of the wearer or to be worn on the lower side of the hip bone. Disposable clothing 1 does not need to make the waist part 21 wider than necessary because the body wearing part 20 is stretchable, so there is no risk of the upper end of the waist part 21 leaking from pants, skirts, etc. during wearing. The appearance is good, and the wearer can wear it without resistance or discomfort.

FIG. 12A shows that the linear elastic body 202 is arranged in the vertical direction at the center part of the front and/or rear part of the disposable garment 1, and the linear elastic body 202 is arranged in the left and right directions on both sides of the disposable garment 1 的例。 Examples.

FIG. 12B shows an example in which the linear elastic body 202 is arranged in the vertical direction only in the center part of the front part and/or the rear part of the disposable garment 1. The disposable clothing 1 can also be formed by combining the pattern shown in FIG. 12A with the pattern shown in FIG. 12B on the front side and the back side. In addition, the front side or back side of the disposable clothing 1 may be the pattern of any one of FIGS. 12A and 12B, and the opposite side may be a combination of no linear elastic body, or the combination of FIGS. 11A to 11I, etc. The combination of patterns shown. By doing so, the linear elastic body 202 can press the absorbent body against the body through the body or the elastic sheet 17.

The disposable clothing 1 of the present invention is shown in Fig. 13B, and the waist part 21 and the body part wearing part 20 can be integrally formed by a stretchable composite sheet, as shown in Fig. 13A and Fig. 13C, or by different individuals. The components are constituted. When the waist section 21 and the trunk wearing section 20 are composed of different individual members, as shown in FIG. If the joint 21a is formed and integrated, the body can be pressed more.

In addition, as shown in FIG. 13C, if a joint 21a is formed and integrated between the outer side of the lower end of the waist portion 21 and the inner side (body side) of the upper end of the body portion wearing portion 20, the body can be prevented from being excessively fastened. In order to join the waist portion 21 and the trunk wearing portion 20, methods such as bonding by hot melt adhesive, stitching, heat sealing, and ultrasonic bonding can be cited. If the waist part 21 and the body part wearing part 20 are integrally formed by a stretchable composite sheet, the manufacture of the disposable garment 1 is easy. On the other hand, if the waist part 21 and the body part wearing part 20 are composed of different individual components, the waist part 21 and the body part wearing part 20 can be made different in elasticity, or the thickness and material of the components can be changed. Heat retention, air permeability, skin feel, etc. are easily different. Also, it is manufactured by combining the waist part 21 and the body part wearing part 20 which will be manufactured in different manufacturing places, or the pollution may occur. In the case of dirt, the waist part 21 and the body part wearing part 20 can also be separated, and the dirt part can be replaced.

When the stretchable composite sheet formed by interposing a liquid diffusing fibrous sheet such as a paper sheet and a linear elastic body between breathable sheets such as non-woven fabrics as described above constitutes disposable clothing, it is the same as that of non-woven fabrics. Compared with the conventional ones with interposed elastomers, the manufacturing becomes easier and the manufacturing cost is reduced, and the disposal of disposable clothes after use becomes easier. That is, since the non-woven fabric has a low affinity with hot melt adhesives, in order to make the sheet have the necessary strength as clothing, it is necessary to use a large amount of hot melt adhesive in order to join the non-woven fabric and the elastomer to each other. Bonding also takes a long time. In contrast, since liquid diffusing fibrous sheets such as paper sheets have a higher affinity for hot melt adhesives than non-woven fabrics, sufficient bonding strength can be obtained even with a small amount of hot melt adhesive, so that hot melt can be achieved. The amount of glue used is reduced, and the bonding time is shortened. There is no need to use complicated devices for bonding, and the manufacturing becomes easier. In addition, in order to obtain the required strength of the stretchable composite sheet, conventional methods such as increasing the amount of hot melt adhesive used, or superimposing two or more layers of non-woven fabrics and joining them are conventionally used. Therefore, although the strength is improved, it is not easy to break when discarded. Off. In contrast, in the case of a stretchable composite sheet formed by interposing a liquid-diffusing fiber sheet such as a paper sheet between air-permeable sheets such as non-woven fabric, the affinity between the liquid-diffusing fiber sheet and the hot melt adhesive It has good properties, which can reduce the amount of hot melt adhesive used, and the strength of the entire sheet is improved by the presence of the liquid diffusing fiber sheet, so even if the non-woven fabric and other breathable sheets are not overlapped, the demand can be obtained. The strength. Therefore, disposable clothing with sufficient strength can be easily obtained, and can be easily broken and discarded after use.

(Elastic sheet)

When the disposable clothing 1 of the present invention is used as a diaper, it can also be installed from the front part 20a to the rear part 20b inside the body part wearing part 20, passing under the crotch of the wearer P. Stretched elastic sheet 17. The elastic sheet 17 may be formed by joining a rope-shaped rubber to a sheet member such as non-woven fabric, moisture-permeable film, paper, etc., or it may be rubber, urethane, or silicon sheet with its own elasticity. , Stocking-like materials, knitted fabrics, etc. If the elastic sheet 17 is provided, the pressure of the absorbent body on the body is further improved, and the shape of the genitals and urinary organs can be hidden during wearing, and it can also be used as a substitute for body protection. Preferably, the elastic sheet 17 is provided so as to be stretchable in the longitudinal direction (the direction from the front part 20a of the trunk part wearing part 20 to the rear part 20b). The absorbent body 10 can be provided inside the elastic sheet 17. When the absorber 10 is provided on the elastic sheet 17, the absorber 10 is pressed to the side of the body due to the contraction force of the elastic sheet 17 stretched during wearing and the contraction force of the body part wearing part 20 having elasticity , The convex swelling of the absorbent body 10 during wearing is suppressed, the gap between the body and the absorbent body 10 is reduced, and the adhesion to the body is improved. Therefore, compared with the conventional one in which only a stretchable elastic sheet is provided and only an absorber is provided on the elastic sheet, swelling in the lower part of the crotch 20c is suppressed, and the appearance and wearing feeling are improved. If the elastic sheet 17 is installed in such a way that the expansion and contraction direction of the elastic sheet 17 crosses the direction of expansion and contraction of the body part wearing part 20, when the body part wearing part 20 is stretched while wearing disposable clothes, the elastic sheet The front-side joint portion and the rear-side joint portion of 17 and the trunk wearing portion 20 are pulled in a direction in which the distance between each other is widened, the elastic sheet 17 is stretched, and the entire elastic sheet is lifted upward. Therefore, the absorber 10 attached to the elastic sheet 17 is pressed toward the body, and the adhesion of the absorber 10 to the body is improved. In particular, if the elastic sheet 17 is provided in such a way that the stretch direction is intersecting the stretch direction of the lower crotch with respect to the stretchable lower part of the crotch where the elastic member 202 is arranged, if the body part is worn by the wearer 20 stretches in the width direction, especially the opening 20f around the leg stretches in the width direction, thereby pressing the lower part of the crotch upward, and the pressing force of the lower part of the crotch and the pressing force of the elastic sheet are combined with each other, so that the absorbent body 10 can be firmly adhered To the body. Also, even by wearing The body part wearing part 20 fluctuates due to the movement of the person. Since the body part wearing part 20 and the elastic sheet 17 are composed of different members, the influence on the variation of the elastic sheet 17 is less. Thereby, when the absorber 10 described below is joined to the elastic sheet 17, the absorber 10 can continue to press the body, so that the absorber 10 can prevent the leakage of sweat or urine.

The elastic sheet 17 can be composed of the same stretchable composite sheet as the body part wearing part 20. As the stretchable composite sheet, for example, as shown in FIG. 14, it can be sandwiched between two nonwoven fabrics 221, 221 It is composed of a liquid diffusing fiber sheet 223 and an elastic member 222 such as a rubber thread. The liquid diffusing fibrous sheet 223 may be arranged on the body side of the elastic member 222 or not arranged on the body side of the elastic member 222. If the elastic sheet 17 is provided with the liquid diffusing fibrous sheet 223, even when urine leaks from the absorbent body such as when the wearer turns over, the liquid diffusing fibrous sheet 223 in the elastic sheet 17 can be used. And absorb the leaked urine. As the elastic member 222, the same one as the linear elastic body in the stretchable composite sheet can be used.

(Change of elastic sheet)

15 and 16 show different aspects of the elastic sheet 17. As shown in FIG. 15 and FIG. 16, the elastic sheet 17 is not limited to the one in which the elastic member 222 is arranged in the entire sheet, and may be one in which the elastic member is arranged in a part of the elastic sheet 17. In addition, elastic members with different elastic forces may be used in combination.

The elastic sheet 17 shown in FIG. 15A is an elastic member 222 that is evenly arranged in the longitudinal direction of the elastic sheet 17.

The elastic sheet 17 shown in FIG. 15B does not have an elastic member at the center, but an elastic member 222 is provided at the front and rear ends in the longitudinal direction.

The elastic sheet 17 shown in FIG. 15C is used as the elastic member 222, using elastic The stronger elastic member 222a and the weaker elastic member 222b are arranged on the side portion, and the elastic member 222b is arranged on the other part. In this case, since the elastic member 222a of the side part has strong elasticity, the adhesiveness to the body side becomes high, and the effect of suppressing side leakage of urine and the like becomes high. On the other hand, the adhesion to the body side other than the side portion is lower than that of the side portion, so there is no feeling of pressure.

In the elastic sheet 17 shown in FIG. 15D, an elastic member 222a with stronger elasticity is arranged in the center part, and an elastic member 222b with weaker elasticity is arranged on the other part. In this case, since the elastic member 222a at the center is more elastic, it fits into the recess of the buttocks, and the wearability is better.

The elastic sheet 17 shown in Fig. 15E has elastic members 222a with stronger elasticity arranged on the side portions, and elastic members 222b with weaker elasticity are arranged on the other parts except the central part, and the central parts are respectively arranged locally. There are elastic members 222a with stronger elasticity and elastic members 222b with weaker elasticity. In this case, since the elastic member 222a of the side portion has strong elasticity, the adhesion to the body side becomes higher, and the effect of suppressing side leakage of urine and the like becomes higher. The adhesion to the side of the body other than the side part is lower than that of the side part, so there is less pressure. In addition, if it is used in such a way that the side where the elastic member 222a with strong elasticity at the center portion is arranged becomes the buttocks side, it fits into the recess of the wearer's buttocks, and the wearability is better.

The elastic sheet 17 shown in FIG. 15F is arranged by bending the elastic member 222 on both sides.

The elastic sheet 17 shown in FIG. 15G is in the side part. The interval between adjacent elastic members 222 is relatively narrow, and the elastic members 222 are densely arranged. width. In this case, the adhesion to the side of the body becomes higher, and urine, etc. The side leakage suppression effect becomes higher. On the other hand, the adhesion to the body side other than the side portion is lower than that of the side portion, so there is no feeling of pressure.

The elastic sheet 17 shown in FIG. 15H is that the elastic member 222 is not continuous in the longitudinal direction, but is intermittently provided.

The elastic sheet 17 shown in FIG. 15I is used as the elastic member 222, and the elastic member 222a with stronger elasticity and the elastic member 222b with weaker elasticity are alternately connected.

The elastic sheet 17 shown in FIG. 15J is arranged by bending the elastic member 222 back and forth.

The elastic sheet 17 shown in FIG. 16A does not have elasticity in the front and rear ends of the elastic sheet 17, and an elastic member 222 is joined to the center of the elastic sheet 17.

The elastic sheet 17 shown in FIG. 16B is provided with elastic members 222a with stronger elasticity at the front and rear ends of the elastic sheet 17, and elastic members 222b with weaker elasticity are arranged at the central part. In this case, the front and rear parts of the elastic sheet 17 have stronger elasticity due to the elastic member 222a, so the adhesion to the body side becomes higher, and the effect of restraining side leakage of urine etc. becomes higher. Furthermore, it fits into the recesses of the buttocks. , Better wearability. On the other hand, the adhesion of the central part to the side of the body is lower than that of the side parts, so there is less pressure.

The elastic sheet 17 shown in FIG. 16C is an elastic member 222 that is not linear, but is arranged undulating.

In the elastic sheet 17 shown in FIG. 16D, the elastic members 222 are arranged in the longitudinal direction and the short-side direction, and they cross each other.

In the elastic sheet 17 shown in FIG. 16E, the elastic members 222 are arranged diagonally and crossed in a lattice shape.

The elastic sheet 17 shown in FIG. 16F is a combination of FIG. 15F and FIG. 16C. The central portion of the elastic sheet 17 is a wave-shaped elastic member 222 arranged in the longitudinal direction, and a curved elastic member 222 is arranged on the side portion.

The elastic sheet 17 is not limited to these forms, and may be a combination of the above-mentioned FIGS. 15A to 15J and FIGS. 16A to 16F. In addition, the strength of the elastic member 222 can be adjusted according to the thickness of the elastic member 222, the strength of extension, the narrowness of the pitch, whether to join continuously or intermittently, and so on.

The elastic sheet 17 shown in FIGS. 15A to 15J and FIGS. 16A to 16F is rectangular, but it is not limited to this. For example, it may have a shape with wider ends as shown in FIG. 16G. By adopting such a shape, the side portion of the elastic sheet 17 will not contact the leg of the wearer, and the feeling of use can be improved. When the elastic sheet 17 of this shape is attached to the body part wearing part 20, it will become a diaper type as shown in FIG. 16H.

As described above, in the elastic sheet 17, the elastic member 222 is arranged in various forms in the direction extending from the front part of the body part wearing part 20 to the rear part. Therefore, due to the contraction force of the elastic member 222, wrinkles are generated on the surface of the elastic sheet 17 to form more gaps between the elastic sheet 17 and the body. Therefore, the air permeability of the elastic sheet 17 can be improved.

As shown in FIG. 17, the elastic sheet 17 may have elastic members 222b arranged in the width direction at both ends of the elastic sheet to have the elasticity in the width direction, and the elastic member 222a may be arranged in the longitudinal direction in the center part to have the length in the direction. The direction of flexibility is constructed in a way. In this case, when the elastic sheet 17 is joined to the trunk wearing part 20 at both ends of the elastic sheet 17, there is no risk of hindering the stretchability of the trunk wearing part 20 in the waist circumference direction.

Also, as shown in an example in FIG. 15A, it can also be arranged inside the elastic sheet 17 Liquid diffusing fibrous sheet 223 such as a paper sheet. The change in disposing the liquid diffusing fibrous sheet 223 inside the elastic sheet 17 is the same as the elastic sheet 17 shown in FIGS. 15A to 15J and 16A to 16G described above. Since the liquid diffusing fibrous sheet 223 is arranged inside the elastic sheet 17, it is assumed that the liquid diffusing fibrous sheet 223 can absorb urine etc. even when urine etc. leak from the absorbent body 10 The suppression effect of side leakage is further improved. In addition, since the liquid diffusing fiber sheet 223 is prone to wrinkles on the surface, many gaps are formed in the elastic sheet 17. Therefore, the air permeability of the elastic sheet 17 can be improved. The elastic sheet 17 may also be embossed. The embossing process may be applied to the liquid diffusing fiber sheet 223 before being inserted into the elastic sheet 17, but it can also be applied to the elastic sheet 17 after the liquid diffusing fiber sheet 223 is embedded in the elastic sheet 17. . If the elastic sheet 17 or the liquid diffusing fibrous sheet 223 is embossed, the flexibility of the elastic sheet 17 can be improved, and the touch of the skin can be further improved, thereby making the absorbent body 10 more effective against the wearer’s body. The adhesion is improved.

(Joint of elastic sheet and absorber)

FIG. 18 and FIG. 19 are diagrams illustrating the joining of the elastic sheet 17 and the absorbent body 10. FIG. 18A is a plan view of the elastic sheet 17 to which the absorber 10 is joined. 18B is a longitudinal cross-sectional view along the longitudinal direction of the elastic sheet 17 to which the absorbent body 10 is joined, and is a longitudinal cross-sectional view along the line X-X' of FIG. 18A. Fig. 18C is a longitudinal sectional view along the width direction of the elastic sheet 17, and is a longitudinal sectional view along the line Y-Y' of Fig. 18A.

As shown in FIG. 18 and FIG. 19, the elastic sheet 17 and the absorber 10 are joined by an adhesive 16. In the example shown in FIG. 18, the adhesive 16 is applied to two locations along the length direction of the elastic sheet 17. As shown in FIG. 18A, the adhesive 16 is applied to the inner side of the both ends 10a, 10b of the absorbent body 10 in the longitudinal direction at two locations, and the adhesive The non-joining portion 30 is formed outside the area surrounded by the agent 16. In the non-joined portion 30, compared with the case where the absorber 10 is joined to the elastic sheet 17 in the vicinity of the both ends 10a, 10b of the absorber 10, it is not bound by the elastic sheet 17, and can be freely moved either above or below Local activities. In addition, when the absorbent body 10 is joined to the elastic sheet 17 in the vicinity of the end portions 10a, 10b, if the absorbent body 10 is located more inside than the end portions 10a, 10b of the absorbent body 10, the adhesive 16 is used to When the absorber 10 is joined to the elastic sheet 17, the absorber 10 can be reliably pressed to the body by the elastic sheet 17 at a portion outside the portion sandwiched by the adhesive 16 and the adhesive 16.

Therefore, if the wearer wears disposable clothing 1, in the length direction of the elastic sheet 17, as shown in FIG. 18B, the stretchability of the elastic sheet 17 is not hindered, and the ends of the elastic sheet 17 and the absorbent body 10 are upward Fang promotion. Similarly, in the width direction of the elastic sheet 17, as shown in FIG. 18C, the ends of the elastic sheet 17 and the absorber 10 are lifted upward. Thereby, the adhesiveness of the elastic sheet 17 and the absorber 10 to the wearer is improved, and the adhesiveness of the absorber 10 to the wearer's body can be improved, so urine leakage and the like can be suppressed. In addition, when the ends of the elastic sheet 17 and the absorbent body 10 are lifted upward, the bent portion formed on the outer periphery of the absorbent body 10 (side edges in the width direction) rises up to form three-dimensional side wrinkles. The wrinkles prevent the outflow of urine and the like. In addition, by forming side wrinkles, a gap is created between the absorbent body 10 and the body in the width direction of the absorbent body 10, thereby ensuring air permeability.

FIG. 19 shows a different example of joining between the elastic sheet 17 and the absorbent body 10. As shown in FIG.

As shown in FIG. 19A, the elastic sheet 17 and the absorber 10 are connected in the longitudinal direction of the elastic sheet 17 by the adhesive 16 applied to one part of the center. By applying the adhesive 16 to one part of the central part as shown in FIG. 19A, the area of the non-joining part 30 can be made wider than that of the non-joining part 30 shown in FIG. 18A, so that the elastic sheet is not hindered Material 17 expansion and contraction The area of sex is wider.

Therefore, if the wearer wears the disposable clothing 1, in the longitudinal direction of the elastic sheet 17, as shown in FIG. And you can press the crotch of the wearer from directly below. Thereby, compared to the conventional disposable diaper constructed by lifting the both ends of the absorbent body 10 in the longitudinal direction, the elastic sheet 17 and the absorbent body 10 can be more closely adhered to the wearer, and therefore can be Furthermore, the leakage of urine, etc. is effectively suppressed.

In addition, in the conventional disposable diaper in which the absorbent body 10 is mounted by lifting the both ends of the absorbent body 10 in the longitudinal direction, if the absorbent body 10 has low flexibility (less slack), the absorbent body 10 is The adhesion of the wearer deteriorates. However, in the disposable clothing 1 of the present embodiment, even when the flexibility of the absorbent body 10 is low, the both ends of the absorbent body 10 in the longitudinal direction can be forcibly forced by the elastic sheet 17 As it lifts upward, the adhesion between the absorbent body 10 and the wearer can be further improved. If the absorbent body 10 is joined while the elastic sheet 17 is stretched, it is difficult to maintain the stretched state of the elastic sheet 17, and positioning takes time. Therefore, the joining takes time and effort, so it is better not to stretch the elastic sheet. The absorbent body 10 is joined in a state where the sheet 17 is stretched.

Furthermore, another embodiment of the elastic sheet 17 is shown in FIG. 20. As shown in FIG. 20, the width of the elastic sheet 17 may be approximately the same as the width of the absorber 10, and notches 17c may be provided on both sides of the elastic sheet 17 in the width direction. The notch 17c is set at the part that contacts the wearer's thigh when the wearer wears the disposable clothing 1. In addition, the elastic sheet 17 is provided with a cutting portion such as a stitch hole 17d in the width direction, and the elastic sheet 17 is cut in the stitch hole 17d as necessary, thereby also removing the pressing force of the elastic sheet 17. Suture hole 17d system and elastic sheet 17 It doesn't matter how the shape is, it can be set on the elastic sheet 17. When the width of the elastic sheet 17 is approximately the same as the width of the absorber 10, when the wearer wears the disposable clothing 1, the two sides of the elastic sheet 17 and the absorber 10 in the width direction are in contact with each other in a supporting manner Wearing on the thighs of the wearer, especially when non-woven fabrics are used for the elastic sheet 17 and the absorbent body 10, the wearing comfort is reduced. In contrast, as in the present embodiment, the elastic sheet 17 is provided with a notch 17c at the portion contacting the wearer's thigh, and the elastic sheet 17 is not easy to contact the wearer's thigh, so it can be improved. Comfortable to wear.

The bonding method between the elastic sheet 17 and the absorbent body 10 is not limited to the adhesive 16 such as hot melt. For example, in addition to sewing and heat sealing, it may be bonding using ultrasonic waves, double-sided tape, etc., and other known methods. Any one of the methods, or a combination of the same. Furthermore, the connection between the elastic sheet 17 and the absorbent body 10 may also use surface fasteners, hooks, buttons, and the like.

(Joining the elastic sheet to the wearing part of the body)

As shown in FIG. 2, the elastic sheet 17 is joined to the front part 20a of the trunk wearing part 20 in one end region in the longitudinal direction, and the other end region in the longitudinal direction is joined to the rear part 20b of the trunk wearing part 20, and the elastic sheet 17 is from The front part 20a of the trunk|body part wearing part 20 spreads over the back part 20b, and is spanned on the upper surface side of the crotch part 20c. Furthermore, here, the so-called one end area and the other end area of the elastic sheet 17 may not necessarily include the end portion, and may be an area separated from the end portion. Furthermore, the elastic sheet 17 may also be configured by a method such as a surface fastener, an adhesive tape, or the like that can be attached to and detached from the body part wearing part 20.

If only the end of the elastic sheet 17 in the longitudinal direction is joined to the trunk wearing portion 20, the entire surface of the elastic sheet 17 is joined to the trunk wearing portion 20, and the elastic sheet 17 will not be hindered. Or of the body part wearing part 20 that overlaps with the elastic sheet 17 Stretchability, while maintaining stretchability in the area other than the junction with the elastic sheet 17 in the body part wearing part 20. Therefore, the wearer can easily wear the disposable clothing 1. Since the elastic sheet 17 and the stretchability of the body part wearing part of the part overlapping with the elastic sheet 17 are not hindered, when the elastic sheet 17 is attached to the absorbent body 10, the pressing force of the body part wearing part 20 The pressing force with the elastic sheet 17 acts on the absorbent body 10, and the absorbent body 10 is surely pressed to the wearer.

FIG. 21 shows an example in which both ends of the elastic sheet 17 are joined to the joining part C1 at a position above the body part wearing part 20 compared to the case shown in FIG. 2. In this case, if the wearer P wears the disposable clothing 1, both the elastic force of the elastic sheet 17 and the elastic force of the body part wearing part 20 act on the wearer P. When the absorbent body 10 is installed , The absorber 10 is surely pressed to the wearer's side. The elastic sheet 17 may be joined to the upper side of the center part of the body part wearing part 20, or may be joined to the lower side. If the elastic sheet 17 is joined as shown in FIG. 2 between the front part of the body part wearing part 20 and the lower part of the center part of the rear part, the pressing force of the elastic sheet 17 can be made to be higher than the center or higher. It is weaker when the central part is joined to the upper part. However, it becomes a product suitable for wearers who do not like to press the absorbent body 10 strongly to the side of the body. Moreover, when the elastic sheet 17 is joined to the lower side than the center of the body part wearing part 20, the absorbent body 10 can be strongly pressed to the body side, and the length of the elastic sheet 17 can be shortened. The manufacturing cost of the elastic sheet 17 is cheap.

Fig. 22 shows the joining state of the elastic sheet 17 and the body part wearing part 20, Fig. 22A shows the end edge of the elastic sheet 17 as the joint part C1 with the body part wearing part 20, and Fig. 22B shows the self-elasticity The position of the edge part of the sheet|seat 17 with the space|interval d1 is set as the junction part C2 (or C3). By doing so, it can be set in such a way that appropriate elasticity can be obtained.

Figures 23A to 23F show the installation of the elastic sheet 17 to the body part wearing part 20 The picture of the change of the outfit. FIG. 23A shows a state in which the two ends of the elastic sheet 17 are joined to the body part wearing part 20 at the joint part C1.

FIG. 23B shows a state in which the end portion of the elastic sheet 17 is separated from the end portion of the elastic sheet 17 in the longitudinal direction by only an interval d1, and the state is joined to the body portion wearing portion 20 at the joint portion C2. Preferably, the interval d1 is set in such a way that an appropriate elastic force is obtained between the joint C2 at the front end and the joint C2 at the rear end in the longitudinal direction of the elastic sheet 17.

FIG. 23C shows a state where the point-shaped joint portion C3 is joined at a position separated from the two ends of the elastic sheet 17 by an interval d1. The number of point-like junctions C3 may be one, or three or more.

FIG. 23D shows the joint at the point-shaped joint C3 at a position separated from the two ends of the elastic sheet 17 by a gap d1, and then at a position separated from the joint C3 by only the gap d2 in the longitudinal direction, at the point-shaped joint The situation of C4 joining. In this case, while maintaining the state of stretching the elastic sheet 17 in the longitudinal direction, the elastic sheet 17 is joined to the joint portions C3 and C4, and the stretch of the elastic sheet 17 is released. In the direction, elastic force can be obtained between the joint C4 at the front end and the joint C4 at the rear end.

If the elastic sheet 17 can be attached in a manner that can ensure the elastic force required by the elastic sheet 17, the attachment position of the elastic sheet 17 to the body part wearing part 20 is arbitrary, but it is preferable that the elastic sheet 17 is paired In the method of installing the body part wearing part 20, it is installed at the position shown in FIG. 23A.

If an elastic sheet 17 composed of a different member is attached to the body part wearing part 20 and an absorber is attached to the elastic sheet 17, the absorber 10 can be held in a state independent of the body part wearing part 20. Therefore, the absorbent body 10 is integrally joined to the body part wearing part 20 Compared with the situation, when the wearer is walking, etc., even if the body wearing part 20 moves with the wearer’s body activity, there is no deviation of the absorber 10 from the predetermined position of the body or the difference between the absorber 10 and the body. There is a risk of creating a gap between them, so that the absorbent body 10 can be more securely attached to the body, and the leakage of sweat or urine can be effectively prevented.

Furthermore, as shown in FIG. 23E, the elastic sheet 17 may be joined to the trunk wearing part 20 at the linear joining part C5 provided along the length direction in the center part of the width direction.

The elastic sheet 17 shown in FIG. 23F is located at the center part in the width direction, and is joined to the trunk wearing part 20 at a plurality of circular joining parts C6 provided along the length direction. In this case, since the plurality of joints C6 are intermittently provided, the stretchability of the elastic sheet 17 in the longitudinal direction can be maintained between the adjacent joints C6 and C6.

FIG. 24 is a diagram showing another variation of the method of attaching the elastic sheet 17 to the trunk wearing portion 20. FIG. In addition, the elastic sheet 17 is joined to the air-permeable sheet 203 arranged on the body side of the body part wearing part 20. The linear elastic bodies 202d to 202f are arranged on the back side, which is the surface opposite to the body side of the air-permeable sheet 203.

In the example shown in FIG. 24A, the elastic sheet 17 is applied to the linear elastic bodies 202d to 202f arranged in the body part wearing part 20 by obliquely and zigzagly between adjacent linear elastic bodies. Hot melt adhesive 19 is joined. The joining with the elastic sheet 17 by the hot melt adhesive 19 makes the linear elastic body 202d and the area A, the linear elastic body 202e and the area C, and the linear elastic body 202f and the area E into one area, respectively. Therefore, the stretchability of the linear elastic body on the body part wearing part 20 is maintained.

In the example shown in FIG. 24B, the elastic sheet 17 is joined at one point at the position where the end of the elastic sheet overlaps the linear elastic body arranged in the body part wearing part 20, and adjacent lines The joint positions of the elastic body and the ends of the elastic sheet are alternately joined in the two ends of the elastic sheet. The position of the elastic sheet 17 on each linear elastic body in the trunk wearing part 20 is a point joint, so the elasticity of each linear elastic body is not lost, and the stretchability of the trunk wearing part 20 can be maintained.

In the example shown in FIG. 24B, in each pressing member, the stretchability in the direction from the area joined with the elastic sheet 17 by the hot melt adhesive 19 to the area where the hot melt adhesive 19 is not applied is respectively maintained. In addition, since the two adjacent pressing members are not joined by the hot melt adhesive 19, in the body part wearing portion 20, there are paper sheets, non-woven fabrics, etc. between the adjacent two pressing members. The flexibility in the horizontal and vertical directions is maintained.

It is not limited to the case where the elastic sheet 17 is attached to the body part wearing part 20, and it can also be attached to the waist part 21 as shown in FIG. In this case, if the wearer P wears disposable clothing 1, the overlapping portion of the elastic sheet 17 and the waist portion 21 is pressed from the waist portion 21 to the wearer P, so the elastic sheet 17 does not distort and press the wearer , Stability is improved.

(Other joining forms of elastic sheet)

FIGS. 26 and 27 are diagrams showing other changes in the method of mounting the elastic sheet 17. In each of the sub-views of FIG. 26 and FIG. 27, the side where the elastic sheet 17 is located is the body side. In addition, FIG. 28 is a diagram illustrating the installation position of the elastic sheet 17 in the configuration of FIG. 27. The following description takes the case where the air-permeable sheet is a non-woven fabric as an example.

In the aspect shown in FIG. 26A, the waist part 21 and the body part wearing part 20 are joined at the joining part C1, and one end of the elastic sheet 17 is joined to the extension 21 b of the waist part 21 at the joining part C2. The extension 21b joined to the end of the elastic sheet 17 may have either a linear elastic body 202 or no linear elastic body 202. As shown in FIG. 27A, the elastic sheet 17 may also be joined to where there is no linear The extension 21b of the elastic body 202.

Here, the attachment position of the elastic sheet 17 when the linear elastic body 202 falls off from the extension part 21b is demonstrated.

FIG. 28 is a schematic diagram of the waist portion 21 and the extension portion 21b of the waist portion 21 when viewed from the side of the body. When the elastic sheet 17 is joined to the waist part 21 (for example, refer to FIG. 25), the elastic sheet 17 is joined in a state where the waist part 21 is most extended in the lateral direction. The reason is that if the elastic sheet 17 is joined in a state where the waist portion 21 is not stretched (hereinafter also referred to as the "recovered state"), when the waist portion 21 is stretched in the lateral direction, only the width of the elastic sheet 17 The elongation margin of part of the waist part 21 becomes less. Therefore, when the elastic sheet 17 is joined to the waist portion 21, the elastic sheet 17 is joined in a state where the waist portion 21 is most extended in the horizontal direction, thereby effectively utilizing the elasticity of the waist portion 21.

On the other hand, as shown in FIG. 27A, when the elastic sheet 17 is joined to the extension portion 21b where the linear elastic body is not present, the elastic sheet 17 is joined while the waist portion 21 is extended in the lateral direction. Bad. For example, as shown in FIG. 28A, in a state where the waist section 21 is most extended in the horizontal direction, an arbitrary point A-A is set on the waist section 21, and a point B-B is set at the same position of the extension section 21b. If the waist portion 21 is restored in this state, as shown in FIG. 28B, the gap between the points A'-A' set on the waist portion 21 and the points B'-B' set on the extension 21b The interval produces a deviation of △x. The reason is that in the extension part 21b, due to the wireless elastic body 202, the extension part 21b has a smaller expansion and contraction effect than the waist part 21. The occurrence of this amount of deviation causes wrinkles to be formed at both ends of the elastic sheet 17. If the wrinkles are formed on the elastic sheet 17, the adhesion of the elastic sheet 17 to the wearer is reduced. If the elastic sheet 17 is joined to the extension portion 21b without the linear elastic body without extending the waist portion 21, the end of the elastic sheet 17 will not shrink even if the waist portion 21 is stretched and the elastic sheet 17 will not be stretched. The sheet 17 is wrinkled. As a result, it won’t be more flexible A gap is formed between the sheet 17 and the wearer, and the elastic sheet can be reliably brought into close contact with the wearer.

When the disposable clothing 1 is of a single size (uniform size), it is worn between the waist 21 from the most extended state to the least extended state. Therefore, when the wearer's waist circumference is large, the deviation amount is small, and as the wearer's waist circumference becomes smaller, the deviation amount becomes larger. In this way, if the elastic sheet 17 is joined in a state where the waist portion 21 is stretched in the lateral direction, the wearing feeling differs according to the wearer's body shape. Particularly, in the case of a wearer with a small waist, the amount of deviation becomes large, so that when the legs are moved, the elastic sheet 17 is likely to have gaps in the width direction, and the adhesion is deteriorated. However, as shown in FIGS. 27A to 27D, when the linear elastic body is detached from the extension 21b of the waist portion 21 and the elastic sheet 17 is joined, the amount of deviation caused by the size of the wearer's waist can be changed Inhibition is minimal. As a result, even when the wearer's waist circumference is small, the deviation does not become large. Therefore, when the legs are moved, the elastic sheet 17 is less likely to have gaps in the lateral direction, and the adhesion is improved. Therefore, it is possible to provide a better wearing feeling for wearers of various body types wearing single-size disposable clothing 1. Furthermore, regarding FIGS. 27B to 27D, the description will be made while comparing the configuration with the corresponding configuration of FIG. 26.

In the embodiment shown in Figs. 26A and 26B to Fig. 26D and Fig. 26H, it is more desirable to combine the joining part C1 of the waist part 21 and the body part wearing part 20 to the elastic sheet 17 and the waist part 21 or body part The interval d1 between the joining part C2 of the wearing part 20 is set to 3 mm or more. By setting the interval d1 to 3mm or more, when the joint C2 is formed by heat sealing, it is possible to suppress the heat of the waist part 21 located near the joint C2 or the linear elastic body arranged on the body part wearing part 20 The impact caused.

In the configuration shown in FIG. 26A, an extension 21b of the waist 21 is formed on the body side of the junction C1 of the waist 21 and the trunk wearing part 20, and the extension 21b is at the junction C1. C2 is joined to the end of the elastic sheet 17.

In the aspect shown in FIG. 26B, the non-woven fabric 215 on the body side of the waist portion 21 forms an extension portion 21b extending from the junction C1 of the waist portion 21 and the body part wearing portion 20, and the end of the elastic sheet 17 is at the junction portion C2 is joined to the extension 21b.

In the aspect shown in FIG. 26C, the upper end of the body portion wearing portion 20 is formed with an extension portion 22a extending from the junction C1 of the waist portion 21 and the body portion wearing portion 20 to the body side, and the end portion of the elastic sheet 17 is at the junction portion C2 is joined to the extension 22a. The extension portion 22a may not have the linear elastic body 202 as shown in FIG. 26B.

In the aspect shown in FIG. 26D, the non-woven fabric 225 located on the outer side of the body part wearing part 20 is formed with an extension part 22a extending from the waist part 21 and the body part wearing part C1 to the body side, and the end of the elastic sheet 17 The part is joined to the extension part 22a at the joint part C2.

In the aspect shown in FIG. 26E, the overlapping portion between the end of the waist portion 21 and the end of the body portion wearing portion 20 sandwiches the end of the elastic sheet 17 and is joined to the joining portion C3. The overlapping portion between the end of the waist portion 21 and the end of the body portion wearing portion 20 may also be configured such that the end portion of the body portion wearing portion 20 is on the side of the body. In addition, as shown in FIG. 27C, the linear elastic body 202 may not be present at the end of the waist portion 21 and the end of the trunk wearing portion 20 in the overlapping portion.

In the aspect shown in FIG. 26F, in the junction C1 of the waist portion 21 and the trunk wearing part 20, the end of the elastic sheet 17 is joined to the body side of the trunk wearing part 20 at the junction C3. In this case, as shown in FIG. 27D, the end of the waist portion 21 in the joint C1 and the end of the body portion wearing portion 20 may not have the linear elastic body 202.

In the aspect shown in FIG. 26G, the outer non-woven fabric 225 and the body-side non-woven fabric 226 are joined at the joint C1 to integrally form the waist part 21 and the body part wearing part 20, which are joined together In the position of the joint C1, the end of the elastic sheet 17 and the non-woven fabric 226 on the body side are joined at the joint C3.

In the aspect shown in FIG. 26H, the waist part 21 and the body part wearing part 20 are integrally formed, and the outer non-woven fabric 225 at the upper end of the waist part 21 is made to extend more than the non-woven fabric 226 on the body side and fold back to the body side And the non-woven fabric 226 on the body side is joined at the joining part C1, and the end of the elastic sheet 17 is joined at the joining part C2 at the extension part 21b extending from the joining part C. The position of the joint C where the non-woven fabric 225 folded back and the non-woven fabric 226 on the body side are joined may be a position that can secure a gap d1 between the non-woven fabric 225 and the non-woven fabric 226 on the body side. For example, it may be directly below the part where the non-woven fabric 206 on the body side is folded back.

As shown in FIGS. 26A to 26D and 26H, if the elastic sheet 17 is joined to the extension portions 21b, 22a, even if the waist portion 21 or the body portion wearing portion 20 is stretched due to physical activity, the elastic sheet 17 is also It is not easy to follow the activity and move, so the pressing force of the elastic sheet 17 on the body is less variable. Also, as in the case where the elastic sheet 17 is directly joined to the waist portion 21 or the body wearing portion 20, There is also no possibility of hindering the elasticity of the waist portion 21 or the body portion wearing portion 20. Therefore, there is no risk of the elastic sheet 17 being twisted due to physical activity, the absorbent body 10 can be well bonded to the elastic sheet 17, and the adhesion of the absorbent body 10 to the body can be ensured, and the backflow prevention of urine and the like can be achieved. Excellent. In addition, if the elastic sheet 17 is joined to the extension portion 21b or the extension portion 22a, compared to the case where the elastic sheet 17 is directly joined to the waist portion 21 or the body part wearing portion 20, the joining portion is not the outer surface. Therefore, the junction part is not conspicuous and is excellent in appearance. When the elastic sheet 17 is joined to the extension portions 21b, 22a, even if the ends of the elastic sheet 17 are connected to the outer side of the extension portions 21b, 22a (from the surface of the body) as shown, it is not shown in particular. It can also be connected to the inner side of the extension portions 21b and 22a, but it is preferably connected to the inner side. To join the elastic sheet 17 to the extension In the case of the inner side, it is also possible to join in such a way that the joint part includes the open end of the extension part, but it is preferable to arrange the joint part of the elastic sheet 17 from the base end side of the extension part (the opposite side of the open end part) , Are joined in such a way that a gap is formed between the open end of the extension part and the elastic sheet 17. If the elastic sheet 17 is joined inside the extension portion and a gap is formed between the extension portion and the elastic sheet 17, even when urine leaks from the absorbent body, the extension portion and the elastic sheet 17 The gap also functions as a so-called urine trap, which can reduce the leakage of urine. In addition, when the elastic sheet 17 is joined to the outer side of the extension part, and when the elastic sheet 17 is joined to the inside, it is preferable that there is no linear elastic body in the extension part of the joining elastic sheet 17. In the case where there is no extension of the linear elastic body to join the elastic sheet 17, it is possible to reduce the occurrence of wrinkles in the elastic sheet 17 due to the expansion and contraction of the linear elastic body, or the elastic sheet 17 being twisted. As a result, the absorbent body 10 supported on the elastic sheet 17 is free from wrinkles or twists, and the absorbent body 10 can be reliably adhered to the body.

The elastic sheet 17 may be joined in one end and the other end in the same joining form, or joined in a different joining form. If the elastic sheet 17 is joined by heat sealing or the like, there is a possibility that the linear elastic body 202 arranged in the part may deteriorate. However, in the embodiments shown in FIGS. 26A to 26D, and 27A to 27D, Since there is no linear elastic body 202, or the elastic sheet 17 is joined at a position where the linear elastic body 202 is deteriorated and does not affect the overall stretchability, it will not bring about the pressing force of the disposable clothing 1 on the body Influence. In addition, as shown in FIGS. 26 and 27, if the elastic sheet 17 is joined to the extension 21b of the waist portion 21, the joint portion of the elastic sheet 17 does not appear in the appearance, so it is not only a product with excellent aesthetics, In addition, the elastic sheet 17 does not hinder the stretchability of the stretchable composite sheet in the joint portion, and even when the absorber 10 is attached, it can be formed into a product that has no sense of discomfort compared with ordinary underwear.

In addition, FIGS. 26 and 27 illustrate the case where the elastic sheet 17 is attached, but it can also be applied to the case where the absorber 10 is directly attached instead of the elastic sheet 17.

FIGS. 29A to 29F show a further different aspect of the method of attaching the elastic sheet 17, and show a situation in which the substantially central part in the width direction on the end side of the elastic sheet 17 is attached to the body part wearing part 20.

FIG. 29A shows a state in which the elastic sheet 17 is joined to the body part wearing part 20 in the linear joint C1 in the substantially central part of the two front ends of the elastic sheet 17.

FIG. 29B shows a state in which the circular joining part C2 is joined to the body part wearing part 20 in the substantially central part of the two front ends of the elastic sheet 17.

FIG. 29C shows a state in which the triangle-shaped joining part C3 is joined to the body part wearing part 20 in the substantially central part of the two front ends of the elastic sheet 17 when the elastic sheet 17 is joined.

FIG. 29D shows a state in which the wave-shaped joining part C4 is joined to the body part wearing part 20 in the substantially central part of the two front ends of the elastic sheet 17 when the elastic sheet 17 is joined.

FIG. 29E shows a state in which the elastic sheet 17 is joined to the trunk wearing part 20 at the substantially L-shaped joining part C5 in the approximately central part of the two front ends of the elastic sheet 17.

FIG. 29F shows a state in which the elastic sheet 17 is joined to the body portion wearing part 20 at the X-shaped joint part C6 in the substantially central part of the two front ends of the elastic sheet 17.

In each of the embodiments shown in FIGS. 29A to 29F, since the elastic sheet 17 is installed at the approximate center in the width direction of the end side, the stretchability is not restricted, and the disposable clothing 1 can be closely attached to the body. The sex is more improved.

In each of the embodiments shown in FIGS. 29A to 29F, since the substantially central portion of the elastic sheet 17 is joined to the body portion wearing portion 20, it is difficult to produce irregular horizontal wrinkles, and There is no local slack in the body part wearing part 20. Therefore, compared with ordinary underwear, it has an appearance without any sense of discomfort and becomes a product with excellent aesthetics.

In addition, in each of FIGS. 29A to 29F, the joining parts C1 to C6 only need to be attached to the substantially central part in the width direction on the end side of the elastic sheet 17, and the number is not limited to one. In addition, it is not limited to the shape shown in each figure of FIG. 29A to FIG. 29F, and other shapes may be used, and a plurality of the same or different shapes may be appropriately combined. Furthermore, the joints C1 to C6 shown in each of FIGS. 29A to 29F may be either only the front end or the rear end of the elastic sheet 17, and the other may be used in the joints of other embodiments (for example, , Figure 23A, etc.) join.

36 is a cross-sectional view of the disposable garment 1 in which the elastic sheet 17 is joined to the extension portion 21b of the waist portion 21. As shown in FIG. As shown in the figure, the front end and the rear end of the elastic sheet 17 are joined to the extension portion 21b of the waist portion 21 in the form shown in FIG. 26A. In this way, the elastic sheet 17 does not join its joining part to the body part wearing part 20 but joins it to the extension part 21b, whereby the joining part does not appear in the external appearance, and an excellent appearance can be formed.

When installing the elastic sheet 17, as shown in FIG. Especially when the elastic sheet 17 is directly attached to the body part wearing part 20 or the waist part 21, the extension parts 21b, 22a, if such a cut D is provided in the elastic sheet, it is installed and installed with the cut D interposed therebetween. When the joint portion E is stretched, the cut D is opened when the body portion wearing portion 20 or the waist portion 21 is stretched, so that it does not hinder the extension of the body portion wearing portion 20 or the waist portion 21. Moreover, if the elastic sheet 17 is mounted in this way, when the trunk wearing part 20 or the waist part 21 is stretched, the elastic sheet 17 is pulled toward the trunk wearing part 20 or the waist part 21, and the extension parts 21b, 22a, as shown in the figure. As shown in 31, the edge 17b of the elastic sheet 17 is pulled upward (body side) to form a so-called three-dimensional wrinkle, which prevents urine leakage. The effect is further improved. This three-dimensional wrinkle effect is more effectively manifested by making the elastic force of the center portion of the elastic sheet 17 weaker than the elastic force of the edge portion 17b. In order to make the elastic force of the center portion of the elastic sheet 17 weaker than that of the edge portion 17b, for example, reducing the number of elastic members in the center portion or changing the strength or texture of the elastic members used in the center portion can be used. The elastic force of the center part is weaker than that of the edge part 17b.

As shown in FIG. 32A, the elastic sheet 17 may be joined with a cut D on the inner side of the end, and a joint E may be provided at a position where the cut D is interposed between the elastic sheet 17 and the substantially center of the end of the elastic sheet 17. In this case, when the trunk wearing portion 20 or the waist portion 21 is stretched, the cut D is opened as shown in FIG. 32B, so that it is possible to reduce the hindrance to the extension of the trunk portion 20 or the waist portion 21.

In addition, as shown in FIG. 33A, if a bent portion is formed at both ends of the elastic sheet 17 in the longitudinal direction, the joint E is provided at the bent portion and the elastic sheet 17 is attached, then the stretched body wear part In the case of 20 or waist portion 21, as shown in FIG. 33B, the bending portion is opened in the width direction, so that it is possible to reduce the hindrance to the stretching of the trunk wearing portion 20 or the waist portion 21.

FIG. 34A shows a state in which an elastic sheet 17 having a cut-out portion D at its end is attached to the body portion wearing portion 20 at the joining portion E with the cut-out portion D interposed therebetween. In this case, if the body wearing part 20 is stretched when the disposable clothing 1 is worn, as shown in FIG. The material 17 exerts an upward lifting force. As a result, the elastic sheet 17 applies a pressing force to the wearer from directly below, and the adhesiveness is improved.

35A to 35H are diagrams showing other changes of the elastic sheet 17 attached to the body part wearing part 20. Figures 35A to 35H are shown in order to pass through the author's crotch The following stretchable direction is used as a reference. At least one of the two end regions of the elastic sheet 17 is provided with cutouts D1 to D8, so as to extend in the width direction according to the expansion and contraction of the body wearing portion 20 in the width direction. The change of the elastic sheet 17 that can expand and contract freely. By providing such cutout portions D1 to D8, the elastic sheet 17 can be expanded and contracted in the width direction, and the body portion wearing portion 20 can be expanded and contracted without losing elasticity when the wearer wears it. In FIGS. 35A to 35H, the illustration of the body part wearing part 20 and the absorbent body 10 is omitted, and the elastic sheet 17, the cutout parts D1 to D8, and the joining parts E1 to E8 that are expanded in a plane are shown.

In the elastic sheet 17 shown in FIG. 35A, a plurality of notches D1 having a linear shape are respectively formed in the regions at both ends. The elastic sheet 17 can be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a at the joining part E1. The elastic sheet 17 forms the cut-out portion D1 in this manner, whereby the cut-out portion D1 is opened in the width direction to be joined to the body portion wearing portion 20 at the joint portion E1 and follow the direction of the body portion wearing portion 20. The width direction expands and contracts freely in the width direction. Therefore, it is difficult to restrict the stretchability of the trunk wearing part 20 by joining the elastic sheet 17 with the cutout to the trunk wearing part 20 at the joining part E1, and it is also difficult to restrain the stretch of the elastic sheet when the wearer wears it. Wait. Thereby, when wearing, especially in the periphery of the junction between the elastic sheet 17 and the body part wearing part 20, there is no discomfort in appearance, and it is provided as a disposable clothing with high aesthetics during wearing. .

In addition, the notch portion D1 is formed in a lengthwise shape along the expansion and contraction direction of the elastic sheet 17. In this way, by forming a cut-out shape in a lengthwise shape along the expansion and contraction direction, when the trunk wearing part 20 expands and contracts in the width direction, D1 opens according to the expansion and contraction, thereby allowing it to extend freely in the width direction. Furthermore, the adjacent cut-out portions D1 are formed to be shifted by a predetermined length (P1) from each other in the expansion and contraction direction. Stagger the predetermined length (P1) in this way to form cuts D1 each other, thereby becoming According to the expansion and contraction of the width direction of the trunk|drum wearing part 20, the structure which can perform an appropriate expansion|contraction extension is possible.

The elastic sheet 17 shown in FIG. 35B is in the structure of the elastic sheet 17 in FIG. 35A, and cut portions D2 having a wider pitch than the plurality of cut portions D1 are formed. Similarly, in the joining part E2, the elastic sheet 17 can be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a. The elastic sheet 17 shown in FIG. 35B is also the same as the elastic sheet 17 shown in FIG. 35A. By forming the cut portion D2, even if it is joined to the trunk wearing part 20 at the junction E2, it can follow the trunk wearing part 20 expands and contracts in the width direction and freely expands and contracts in the width direction. Therefore, even if the elastic sheet 17 having the cut-out portion D2 is joined to the body portion wearing portion 20 at the joining portion E2, it is difficult to restrict the stretchability of the body portion wearing portion 20, and the elastic sheet is also suppressed when the wearer wears it. Lehen and so on. As a result, during wearing, especially in the periphery of the junction between the elastic sheet 17 and the body wearing part 20, the stretchability of the body wearing part is not hindered, so there is no sense of discomfort in appearance, and it is used for wearing Disposable clothing with high aesthetics at the time is provided.

In addition, in the joining part E3, the elastic sheet 17 can be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a. In this configuration, the cut portion D3 is formed in the elastic sheet 17 over substantially the entire surface area of the elastic sheet 17. Therefore, even if the elastic sheet 17 is joined to the trunk wearing portion 20 as described above, it is difficult to restrict the trunk wearing The stretchability of the part 20 is the same as the above. When worn, especially in the periphery of the junction between the elastic sheet 17 and the body part wearing part 20, the stretchability of the body part wearing part will not be hindered, so the appearance will not be affected. A sense of harmony is provided as a disposable garment with high aesthetics when worn. In addition, due to the cut-out portion D3 formed in substantially the entire surface area, it will absorb The body, etc. are arranged on the elastic sheet, which also allows moisture and the like to escape and suppresses airtightness, and has better air permeability or moisture permeability.

In the elastic sheet 17 shown in FIG. 35D, the elastic sheet 17 in FIG. 35C is formed with cut portions D4 whose pitch width is wider than the plurality of cut portions D3 in substantially the entire surface area thereof. In addition, in the joining part E4, the elastic sheet 17 can be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a. In this configuration, the notch portion D4 is formed in the elastic sheet 17 over substantially the entire surface area of the elastic sheet 17. Therefore, even if the elastic sheet 17 is joined to the body portion wearing portion 20 as described above, it is difficult to suppress the body portion from being worn. The stretchability of the part 20 is the same as the above. When worn, especially in the periphery of the junction between the elastic sheet 17 and the body part wearing part 20, the stretchability of the body part wearing part will not be hindered, so the appearance will not be affected. A sense of harmony is provided as a disposable garment with high aesthetics when worn. In addition, due to the cut-out portion D4 formed in substantially the entire surface area, even if the absorbent body is arranged on the elastic sheet during wearing, moisture etc. escape and prevent airtightness, etc., and have better air permeability. Sex or moisture permeability.

In the elastic sheet 17 shown in FIG. 35E, the straight cut portion D5 is provided at approximately the center of both ends. In addition, in the joining part E5, the elastic sheet 17 can be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a. In this configuration, similar to the above, even if the elastic sheet 17 is joined to the body portion wearing portion 20, it is difficult to restrict the stretchability of the body portion wearing portion 20. When the wearer wears it, the mounting portion of the elastic sheet is suppressed. Lehen and so on. As a result, during wearing, especially in the periphery of the junction between the elastic sheet 17 and the body wearing part 20, the stretchability of the body wearing part is not hindered, so there is no sense of discomfort in appearance, and it is used for wearing Disposable clothing with high aesthetics at the time is provided.

In the elastic sheet 17 shown in FIG. 35F, the cutout portion D6 is provided at both ends Roughly the center. In the joining portion E6, the elastic sheet 17 can be joined to the trunk wearing portion 20, the waist portion 21, and the extension portions 21b, 22a. In this configuration, similar to the above, even if the elastic sheet 17 is joined to the body portion wearing portion 20, it is difficult to restrict the stretchability of the body portion wearing portion 20. When the wearer wears it, the mounting portion of the elastic sheet is suppressed. Lehen and so on. As a result, during wearing, especially in the periphery of the junction between the elastic sheet 17 and the body wearing part 20, the stretchability of the body wearing part is not hindered, so there is no sense of discomfort in appearance, and it is used for wearing Disposable clothing with high aesthetics at the time is provided.

In addition, here, the shape of the cut portion D6 is formed into a V-shaped notch shape. In this way, in the present invention, the "notch portion" includes not only a straight or curved notch shape, but also a shape having a so-called cut-out portion such as the notch portion D6, and may include the following hole shapes and the like. In this way, by forming a notch shape or a hole shape as the "notch portion", air-impermeability during wearing can be suppressed, and air permeability or moisture permeability can be further improved.

In the elastic sheet 17 shown in FIG. 35G, the cut portion D7 is an elliptical hole. In this case, as the above-mentioned effects, air permeability, moisture permeability, etc. are excellent. The elastic sheet 17 shown in FIG. 35G may also be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a in the joining part E7.

In the elastic sheet 17 shown in FIG. 35H, the cutout portion D8 is a round hole. In this case, as well as the above-mentioned effects, the air permeability, moisture permeability, etc. are excellent. The elastic sheet 17 shown in FIG. 35H may also be joined to the body part wearing part 20, the waist part 21, and the extension parts 21b, 22a in the joining part E8.

In the change of the elastic sheet 17 shown in the respective sub-figures of FIGS. 35A to 35H described above, in the area where at least a plurality of notches are formed, follow the joints of the joints The body part wearing part 20 expands and contracts, and the elastic sheet 17 expands and contracts well in the horizontal width direction. In these embodiments, it is preferable to provide the joint portion at the sheet end of the elastic sheet 17 that assumes the expansion and contraction in the horizontal width direction as shown in FIGS. 35A to 35H. By disposing the joining part in this way, the elastic sheet 17 provided with the cut-out part effectively follows the expansion and contraction of the body part wearing part, and it becomes a disposable garment with the elastic sheet 17 that expands and contracts freely in the width direction.

As mentioned above, according to the changes shown in the sub-figures in Figs. 35A to 35H, the restriction of the stretchability of the body part wearing part 20 is suppressed. When the wearer wears it, it is caused by the elastic sheet (especially with the body part). Partial slack or strangulation in the body part wearing part 20 of the joining part of the wearing part 20 is also suppressed. Thereby, when wearing, especially in the periphery of the junction between the elastic sheet 17 and the body part wearing part 20, there is no discomfort in appearance, and it is provided as a disposable clothing with high aesthetics during wearing. .

(The width of the lower part of the crotch of the body part and the width of the elastic sheet)

When the elastic sheet 17 is provided, as shown in FIG. 37, it is preferable that the width dimension L1 of the lower part of the crotch 20c in the trunk part wearing part 20 does not reach the width dimension of the elastic sheet 17 joined to the trunk part wearing part 20 L2. When L1 is less than L2, there is an effect that the lower part of the crotch of the wearing part of the body part is lifted when wearing disposable clothes, so that the bottom of the absorbent body 10 can be surely pressed in the direction of the body. When the body wearing part 20 moves, the bottom face of the absorbent body 10 is not easy to move, and the pressing point on the body is not easy to deviate. Furthermore, when the absorbent body 10 is directly attached without providing the elastic sheet 17, it is preferable that the width L1 of the lower part of the crotch 20 c is less than the width of the absorbent body 10.

38 is a cross-sectional view of the disposable garment 1 in which a gap S is formed between the lower part of the crotch 20c of the body part wearing part 20 and the elastic sheet 17. As shown in FIG. If it is used in the lower part of the crotch 20c and the elastic sheet When the elastic sheet 17 is installed in such a way that the gap S is formed between the 17, the elastic sheet 17 is more closely attached to the body side, and the pressing force of the elastic sheet 17 is more exerted.

(Method of manufacturing disposable clothes)

Next, the manufacturing method of the shorts-type disposable garment 1 shown in FIG. 38 is demonstrated.

As shown in FIG. 39A, the body part wearing part 20 before being formed into a shorts shape is in a state where the side edge parts 23a, 23b, 24a, and 24b facing each other in the height direction are separated from each other. The elastic sheet 17 is joined to the trunk wearing portion 20 in a state of being stretched in the longitudinal direction. In addition, in this embodiment, an example in which the front end of the elastic sheet 17 is joined to the front part 23 and the rear end is joined to the rear part 24 is shown. If the elastic sheet 17 is joined to the body part wearing part 20 in a state stretched in the longitudinal direction, the elastic sheet 17 returns to its original length due to its stretching force (the length of the elastic sheet 17 shown on the left in the figure) ). Moreover, compared with the body part wearing part 20 joined to the front end and the rear end of the elastic sheet 17 in a state where the elastic sheet 17 is stretched in the longitudinal direction, the elastic sheet 17 which returns to its original length due to the stretching force is longer. Short, so a slack is formed in the lower part of the crotch 20c.

In this state, fold the body part wearing part 20 in the lower part of the crotch 20c so that one of the side edges 23a of the front part 23 overlaps with the corresponding one of the side edges 24a of the rear part 24, and the other side of the front part 23 The edge portion 23b overlaps with the other side edge portion 24b of the rear portion 24 corresponding to each other.

Next, as shown in FIG. 39B, one side edge portion 23a of the overlapping front portion 23 is joined to a corresponding side edge portion 24a of the rear portion 24, and the other side edge portion 23b of the overlapping front portion 23 is similarly joined to the rear portion 24. The corresponding other side edge 24b is joined. The bonding of the sheets may be, for example, any method of heat fusion, stitching, heat sealing, ultrasonic bonding, paste, other known methods, or a combination thereof.

If the respective side edge portions are joined to each other in this way, as shown in FIG. 39C, the body portion wearing portion 20 is formed into a short pants type. The formed body part wearing part 20 is in a state where the elastic sheet 17 is exposed to the outside. In addition, the side edges in the lateral direction (left-right direction) of the body part wearing part 20 are in a state where the joining part C1 performed by joining is exposed to the outside.

Next, as shown in FIG. 39C, the back side before exposing the elastic sheet 17 to the outer body part wearing part 20 is replaced. The shorts-type disposable garment 1 in which the front and back of the body part wearing part 20 is replaced, and the elastic sheet 17 is arranged on the inner side is completed. In addition, by replacing the front and back of the body part wearing part 20, the joining part C1 is also arranged in the inner side. Furthermore, the work of replacing the front and back of the body part wearing part 20 may be performed automatically or semi-automatically using a dedicated device (not shown), or may be performed manually.

Fig. 40 is a schematic diagram showing another manufacturing step of the disposable garment 1 shown in Fig. 39.

As shown in FIG. 40A, in this embodiment, by shrinking the trunk wearing part 20 in the height direction in advance, a gap S is formed between the lower part of the crotch 20 c and the elastic sheet 17. That is, by shrinking the trunk wearing part 20 in the height direction, a slack part 260 is formed in the lower part of the crotch 20c. Furthermore, the elastic sheet 17 is joined to the body part wearing part 20 in which the slack part 260 is formed in the crotch part 20c in the state which is not stretched|stretched.

In this state, fold the body part wearing part 20 in the lower part of the crotch 20c so that one of the side edges 23a of the front part 23 overlaps with the corresponding one of the side edges 24a of the rear part 24, and the other side of the front part 23 The edge portion 23b overlaps with the other side edge portion 24b of the rear portion 24 corresponding to each other.

Next, as shown in FIG. 40B, by joining the corresponding side edge portions of the overlapping front portion 23 and the rear portion 24, a shorts-shaped body portion wearing portion 20 is formed.

Next, as shown in FIG. 40C, the shorts-type disposable garment 1 in which the elastic sheet 17 is placed on the inner side is completed by replacing the front and back of the body portion wearing part 20 exposing the elastic sheet 17 on the outer side. In addition, by replacing the front and back of the body part wearing part 20, the joining part C1 is also arranged in the inner side.

Furthermore, in the embodiment shown in FIG. 39 and FIG. 40, an example in which the front end of the elastic sheet 17 is joined to the front part 23 of the body part wearing part 20 and the rear end is joined to the rear part 24 has been described. Not limited to this. In the body part wearing part 20, the position where the front end and the rear end of the elastic sheet 17 are joined can be applied to various forms described in this specification.

(Different appearances of body parts)

FIG. 41A shows a case where the open ends 26 are formed on both sides of the lower end of the body part wearing part 20. The open end 26 is formed by cutting both sides of the lower end obliquely into a straight line or a curve shape with a cutting machine or the like in a state where the body part wearing part 20 is arranged in a plane. Since the body part wearing part 20 is formed with the open end part 26 and the opening part 27 is formed between the air-permeable sheets 203 and 205, the air permeability can be improved. In addition, the wearer can move his legs more easily. If both sides of the lower end of the body part wearing part 20 are cut, in the cross section of the open end part 26, as shown in FIG. 41B, the end part 202b of the linear elastic body 202 is exposed. At this time, the linear elastic body 202 is in contact with the liquid diffusing fibrous sheet 201 (not shown in FIG. 41), and the linear elastic body 202 is bonded to the liquid by the adhesive applied to the linear elastic body 202 In the case of the diffusing fiber sheet 201, if the fixing portion 218a is particularly formed, the linear elastic body 202 is firmly joined between the air-permeable sheet 205 and the liquid diffusing fiber sheet 201, so that the open end portion 26 The end 202b of the linear elastic body 202 is less likely to be drawn to the inside, maintains the elasticity in the open end 26, and also maintains the adhesion to the body.

On the other hand, if the adhesive dose applied to the linear elastic body 202 is made smaller, as shown in FIG. 41C, in the cut surface of the open end 26, the end 202b of the linear elastic body 202 enters the inside. There is no linear elastic body 202 on the cut surface, and a corrugated hemming portion 300 composed of the air-permeable sheets 203 and 205 and the liquid-diffusing fiber sheet 201 is formed. The hem portion 300 is formed by the subsequent deviation of the end 202b of the linear elastic body 202 when the wearer wears the disposable clothing 1, and the end 202b of the elastic body enters the inside. The amount of penetration of the end 202b of the linear elastic body 202 in the open end 26 to the inside varies according to the degree of extension of the linear elastic body 202 during wearing. The thicker the leg of the wearer, the linear elastic body The greater the degree of extension 202 is, the proper pressing force that matches the size of the leg can be obtained in the periphery of the hem portion 300. Furthermore, when the disposable garment 1 is manufactured, by applying tension to the width direction of the body part wearing part 20, the end 202b of the pressing member 202 enters the inside, and the hem part 300 may also be formed.

If the adhesive dose applied to the linear elastic body 202 is made smaller, it is easier to form the frill part 300 at the open end 26. If the frill part 300 is formed, the wearer can more easily move the legs, and the wavy The appearance can improve the decoration. In addition, in the frill portion 300, an opening 27 is formed between the air-permeable sheets 203 and 205, so that the air permeability can be improved. Furthermore, the hem portion 300 can also be formed by adjusting the length of the linear elastic body 202 in advance so that there is no linear elastic body 202 near the open end 26.

Incidentally, in conventional disposable clothing, for example, in order to obtain tightness around the legs, the legs are formed by arranging an elastic member etc. on the part that is in contact with the circumference of the leg, especially the outermost part of the leg opening. Folds around. This is to prevent the decrease in adhesion caused by the detachment of the pressing member when cutting the circumference of the leg. Therefore, complicated steps are required to make wrinkles around the legs, and multiple processing machines are required. However, according to the configuration of this embodiment, even if When the leg circumference of the body part wearing part 20 is cut separately, the pressing member of the cut part can also be prevented from falling off, so there is no need to form folds around the leg. Thereby, complicated steps and multiple processing machines for making folds around the legs are not required, so that the cost can be reduced.

(Absorber)

Fig. 42A is a plan view of the absorbent body 10, and Fig. 42B is a cross-sectional view taken along line X-X of Fig. 42A.

As shown in the figure, the absorbent body 10 is an elongated substantially rectangular member, and includes a top sheet 11, a back sheet 12, an absorbent core 13 arranged between the top sheet 11 and the back sheet 12, and a bending part 14. When the wearer wears the disposable clothing 1, the bent portion 14 formed on the outer periphery of the absorbent body 10 (side edge in the width direction) rises up and becomes a three-dimensional side wrinkle. In addition, the shape of the absorber 10 is not limited to a rectangular shape, and may be any shape of a contracted shape, an elliptical shape, and other well-known absorbers. In addition, the structure of the absorber 10 is not limited to the above, and may be any known structure.

(Effect)

(1) FIG. 43 is a diagram illustrating the function and effect of the disposable garment 1 of the first embodiment. As shown in the figure, in the state where the absorbent body 10 is arranged on the elastic sheet 17, the wearer P wears the disposable clothes 1. Then, the elastic sheet 17 stretches, so the absorbent body 10 is pressed in the direction toward the body by the force of the elastic sheet 17 to contract. By the pressing force in the direction toward the body, the absorbent body 10 is in close contact with the body. In addition, if the wearer P wears the disposable clothing 1, the body wearing part 20 stretches, so the front part 20a and the back part 20b of the body part wearing part 20 are moved toward the body by the force of the body wearing part 20 to contract. Press in the direction. With this strong pressing force toward the body, the body part wearing part 20 is in close contact with the body.

In particular, if the absorber 10 is arranged on the elastic sheet 17, the absorber 10 can be pressed from the direction directly below the crotch. Thereby, the absorber 10 can be connected to the body more densely than the conventional one.

Thereby, the state of pressing the elastic sheet 17 to the side of the body can be maintained more reliably. In addition, in the disposable garment 1 of the present embodiment, the elastic sheet 17 is pressed in a direction toward the body in the lower part of the crotch 20c of the body part wearing part 20 and its peripheral part. Therefore, the pressing force of the elastic sheet 17 toward the body can be made greater. In this way, the disposable clothing 1 of this embodiment can make the whole body wearing part 20 including the elastic sheet 17 stronger by the synergistic effect of the contraction force of the elastic sheet 17 and the contraction force of the body part wearing part 20 The pressing force is tightly attached to the body.

(2) As shown in FIG. 44A, the body wearing part 20 before the wearer wears the disposable clothing 1 does not deform according to the wearer's buttocks, so the tension of the pressing member 202 in the rear part 20b is approximately uniform across the entire surface. On the other hand, as shown in FIG. 44B, if the wearer wears the disposable clothing 1, the rear part 20b of the body part wearing part 20 deforms according to the shape of the wearer's buttocks. Due to this deformation, the tension of the linear elastic body 202 becomes the highest in the wearer's buttocks, and the tension becomes lower as it faces the waistline direction and the crotch direction. Among them, the linear elastic body 202 arranged on the rear part 20b corresponding to the wearer's buttocks is stretched upwards obliquely from the left and right sides of the wearer's buttocks toward the center, as shown by the arrows in the figure. In addition, in the rear part 20b of the body part wearing part 20, the linear elastic body 202 extended to the outer side of the wearer's waist circumference is about to return to its original state. This recovery action is that the higher the tension of the linear elastic body 202, the stronger the action. As a result, the force that presses the wearer's buttocks toward the center (inside) of the waist circumference acts, and the wearer's buttocks are lifted upward, thereby correcting sagging buttocks. In this way, in the disposable clothing 1 of this embodiment, the force to lift the wearer’s buttocks from the left and right sides to the center obliquely upwards and the wearer’s buttocks to the The synergistic effect of the pressing force in the center direction of the waistline works. As a result, the disposable clothing 1 of the present embodiment can obtain a buttocks lifting effect like a correction underwear, so it can be used as a disposable clothing while allowing the wearer's body lines to appear more beautifully. Incidentally, in the body part wearing part 20 of the present embodiment, by making the strength of the linear elastic body 202 arranged at the rear part 20b stronger than the strength of the pressing member 202 arranged at the front part 20a, the buttocks can be further improved. Enhance the effect.

(3) Fig. 45A is the actual image when observing the conventional disposable diaper from the front side of the wearer. FIG. 45B is an actual image when the disposable garment 1 of the first embodiment is viewed from the front side of the wearer.

As shown in Fig. 45A, the conventional disposable diaper does not have a pressing member arranged to cover the absorbent body provided in the center, so if the wearer wears it, the pressing member arranged around the absorbent body shrinks and the pressing member It sinks between the absorbent body and the wearer's legs (for example, the part shown by the white arrow in the figure). Therefore, the absorbent body bulges to the outside of the body, and others notice that the disposable diaper is worn.

On the other hand, in the disposable garment 1 of the first embodiment, since the linear elastic body is disposed in the entire body portion wearing portion 20, even when the absorber is attached to the elastic sheet 17, the pressing member is also It will not fall between the absorbent body and the wearer's legs. As an example, it can be seen that in the disposable garment 1 of the first embodiment, the portion of the linear elastic body indicated by the white arrow in FIG. 45B has a small amount of sinking. As a result, the absorber does not bulge out to the outside of the body, so it is difficult for others to notice that the disposable clothing 1 with the absorber is worn. In addition, since it has an appearance without discomfort compared with ordinary underwear, it becomes a product with excellent aesthetics.

(4) The disposable clothing 1 of this embodiment can be used to wear the body part 20 The whole body is in close contact with the body. Therefore, when wearing pants, skirts, etc., or taking off pants, skirts, etc., the body part wearing part 20 does not curl up, and it is possible to suppress defects such as exposure of the wearer's skin. Therefore, it does not locally compress the wearer's body like the conventional disposable diaper that only fastens the body at the waist, so a more comfortable and stable wearing feeling can be obtained. In addition, since the body part wearing part 20 is highly stretchable, the legs can be moved easily, and it is of a single size, which can cope with wearers of a wide range of body types. Therefore, it is possible to provide a better wearing feeling for wearers of various body types wearing single-size disposable clothing 1.

(5) The liquid diffusing fibrous sheet 201 used for the disposable clothes 1 is a cheap material such as a paper sheet, which has excellent evapotranspiration, air permeability, moisture absorption, and high whiteness. The liquid diffusing fibrous sheet 201 has moderate heat retention in winter, and can obtain a cool feeling in summer. In addition, it is easy to discard and decompose naturally, so the impact on the environment is also smaller than that of chemical fiber. In addition, the liquid diffusing fibrous sheet 201 is excellent in processability such as perforation and cutting. Furthermore, the liquid diffusing fibrous sheet 201 can improve water resistance or improve surface strength by surface processing.

(6) In addition, due to the humidity control effect of the liquid diffusing fiber sheet 201, the inside of the body part wearing part 20 is maintained at a moderate humidity, so that the disposable clothes 1 can have a moderate affinity. In addition, by generating the affinity, the friction noise of the cloth can be reduced, so that it is difficult for others to notice that the disposable clothes 1 are worn. Furthermore, the so-called cloth rubbing sound refers to the "rusting sound" generated when the components of the disposable clothing 1 rub against the body, the "rusting sound" generated when the components of the disposable clothing 1 rub against each other, and the disposable clothing 1 The "rustle" caused by friction with pants, skirts, etc.

(7) In the disposable garment 1 of the present embodiment, since the liquid diffusing fiber sheet 201 is formed with the concave and convex portions 213, the area through which air passes is increased, so that the air permeability can be further improved. In addition, if the concavities and convexities 213 are formed in the liquid diffusing fiber sheet 201, the contact area of the body is reduced, so when the liquid diffusing fiber sheet 201 absorbs urine or the like, the wearer's discomfort can be suppressed. Moreover, if the concavities and convexities 213 are formed on the liquid diffusing fibrous sheet 201, the surface area is substantially increased even if the size is the same, so that the transpiration, air permeability, moisture permeability, urine absorption, etc. can be improved.

(8) In addition, if the uneven portion 213 is formed on the liquid diffusing fiber sheet 201, when the adhesive is sprayed from a nozzle and applied, the adhesive will not be applied to the entire liquid diffusing fiber sheet 201 The surface is partially coated. Therefore, when the air-permeable sheet is adhered to the liquid-diffusing fibrous sheet 201 by an adhesive, the liquid-diffusing fibrous sheet 201 is locally adhered to the air-permeable sheet, etc., thereby improving the Then the flexibility of the composite sheet obtained. In addition, since more areas for air to pass through can be ensured, the heat retention and cooling sensation can be further improved. That is, by forming the concavities and convexities 213 due to the liquid diffusing fiber sheet 201, it can be warm in winter and cool in summer. In addition, since more areas can be ensured for air to pass through, the humidity can be adjusted appropriately.

(9) In addition, the liquid diffusing fiber sheet 201 forms the concavities and convexities 213, so that the liquid diffusing fiber sheet 201 can be given a three-dimensional effect. Therefore, the disposable clothing 1 can be made into a more three-dimensional shape. In addition, when the liquid diffusing fiber sheet 201 forms the printed layer 201a, the printed photographs and the like can be displayed more realistically.

In addition, when the liquid diffusing fiber sheet 201 is embossed to form the uneven portions 213, the paper quality of the liquid diffusing fiber sheet 201 can be made softer, so that the skin feel during wearing can be further improved .

(10) In the case of conventional paper diapers, etc., the absorbent body is not pressed to The strength of the body is therefore only pressed to the body at the waist. As a result, in order to make the absorber closely adhere to the body, its structure must be made longer. Therefore, when trousers, skirts, etc. are worn in the state of being worn, the upper end of the diapers etc. may be exposed from the trousers, skirts, etc., and others may notice that the diapers are worn. On the other hand, the disposable clothing 1 of the present embodiment has excellent adhesion of the body part wearing part 20 to the body, so the height of the body part wearing part 20 can be made shorter than that of conventional paper diapers, etc., and the disposable clothing can be improved. 1. The beauty or wearing feeling, and can form an appearance that is not uncomfortable compared with ordinary underwear.

(11) Conventional paper diapers and the like have weak power to make the absorbent body adhere to the body. Therefore, in the case of women wearing skirts, they may be worn by overlapping the fastening underwear from the top of the paper diaper. However, in the disposable clothing 1 of this embodiment, even if it is worn without overlapping undergarments for fastening, the absorbent body can be tightly attached to the body with a strong pressing force. Therefore, the disposable clothing 1 of this embodiment is particularly suitable for women wearing skirts.

(12) The disposable clothing 1 of this embodiment is shown in FIG. 38. A gap S can be formed under the part where the elastic sheet 17 and the body part wearing part 20 are joined, so that the disposable clothing 1 can be kept in close contact with the body. It’s easier to move the legs of the author P. In addition, by forming the gap S, the elastic sheet 17 is easily shifted in the lateral direction, so when the wearer is a male, it is easy to urinate. In addition, compared with the case where the elastic sheet 17 is integrally joined to the body portion wearing portion 20, the body portion wearing portion 20A can have a greater pressing force in the direction of the body, and the body portion wearing portion 20 can attach the elastic sheet 17 Press harder toward the body.

(13) With the elastic sheet 17 pressing the entire absorbent body 10, the urine absorbed by the absorbent body 10 not only directly spreads around the part covered by the urine, but also easily spreads around it, and can be compared in the absorbent body 10. It is known that a wider area absorbs urine and so on. Therefore, only one part of the absorber 10 The phenomenon of absorbing urine and bulging out is more relaxed than conventional ones, and the appearance is improved.

Furthermore, if a part of the absorber 10 bulges due to urine or the like, the absorber 10 sags downward due to gravity, but the elastic sheet 17 pushes the absorber 10 upward from below, so the degree of the absorber 10 sag is obtained Soothing, it can suppress the appearance decrease caused by the sagging of the absorbent body 10 that absorbs urine and the like.

(14) As shown in Fig. 43, the body part wearing part 20 that is stretchable when wearing disposable clothes 1 covers the waist to buttocks of the wearer P from above the elastic sheet 17, so it has an excellent sense of stability or fit. .

(15) If the liquid diffusing fiber sheet 201 is provided with a printing layer 201a such as photographs, compared with conventional paper diapers and the like, it is possible to provide clothing with excellent aesthetics, and it can further reduce the wear of the wearer P on the disposable clothing 1 The sense of resistance.

(16) If wrinkles are formed in the elastic sheet 17, the elastic sheet 17 and the absorber 10 are not in contact with the entire surface, so the elastic sheet 17 and the absorber 10 can be joined multiple times. Furthermore, the reason why multiple times of joining can be performed is that since the elastic sheet 17 has wrinkles, the fabric of the absorbent body 10 is not damaged. In addition, the reason is that if the elastic sheet 17 has wrinkles, the absorber 10 is easily separated.

(17) The conventional diaper has insufficient force to press the absorbent body 10 to the body. Therefore, as shown in FIG. 64A, in order to prevent leakage of urine and the like, the width of the absorbent body 10: L3 must be sufficiently wide. As a result, in order to make the opening 20f around the leg a sufficient size, it has to be a brief type as shown in FIG. 64A. On the other hand, when the disposable clothing of the present invention is used as a diaper, the absorber 10 can be pressed against the body and tightly adhered, and there is no risk of urine leakage from the absorber 10, so the width of the absorber 10 can be increased : L4 becomes narrower, even if it is the sports shorts type as shown in Fig. 64B, it is possible to form the openings 20f around the legs of the same size as the briefs type. Since the width of the _{opening 20f around the leg of the short pants type: m 1 is} larger than the width of the opening 20f around the leg of the briefs type: m ₂ , the leg is viewed from the side of the waist opening 21a when the wearer wears it. When the peripheral opening 20f is recognized, it is recognized that the leg peripheral opening 20f of the sports shorts type shown in FIG. 64B is larger than the leg peripheral opening 20f of the brief type shown in FIG. 64A, and it is easy to insert the foot when wearing.

(Second Embodiment)

Fig. 46 is an external view of disposable clothing 1A in the second embodiment. The disposable garment 1 of the second embodiment also includes an elastic sheet 17 spanned between the front part 20a and the rear part 20b of the body part wearing part 20. As shown in FIG.

As shown in FIG. 46 and FIG. 47, the disposable garment 1A of this embodiment is equipped with the trunk|drum wearing part 20, and the elastic sheet 17 spanned between the front part and the back part of the trunk|drum wearing part 20. As shown in FIG. The absorber 10 is arranged on the inner side of the elastic sheet 17 (upper side, wearer side, and skin contact side).

As shown in FIG. 47, the trunk wearing part 20 includes a waist part 21 and a trunk wearing part 20. The waist part 21 is worn on the waist part of the wearer P, and is arranged on the upper part of the body part wearing part 20. The body part wearing part 20 presses the peripheral part of the wearer's lower abdomen, and is formed in an annular shape. That is, the body part wearing part 20 of this embodiment differs from 1st Embodiment in that it does not have a lower part of a crotch.

As shown in FIG. 46, the body part wearing part 20 is roughly the same shape as a general waistband, and has the same height. Furthermore, the body part wearing part 20 is not limited to the example of the present embodiment, and may be a longer seven-minute length, or a shape that covers the upper part of the wearer P's waist. Also, for women, as shown by the imaginary line L in Fig. 46, the height may be the same as that of a short skirt. In this case, by being formed into a shape shorter than the disposable garment 1A shown in FIG. 46 (that is, a substantially V-shaped shape in front view) by cutting both sides into a shape shorter, the legs can be moved more easily.

(Joining the elastic sheet to the wearing part of the body)

(1) Joining of the elastic sheet 17 to the body part wearing part 20

As shown in FIG. 48, the elastic sheet 17 of this embodiment is joined to the center of the front part of the trunk|body part wearing part 20 by the one end area|region of a longitudinal direction. In addition, the other end region in the longitudinal direction is joined to the center of the rear part of the trunk wearing part 20. Furthermore, here, the so-called one end area and the other end area may not necessarily include the end portion, and may be an area separated from the end portion.

In this embodiment, when the elastic sheet 17 is attached to the trunk wearing part 20, the elastic sheet 17 can be joined without extending the trunk wearing part 20, or it can be used to make the trunk wearing part The elastic sheet 17 is joined in the stretched state.

In this way, by fixing one end area in the longitudinal direction and the other end area in the longitudinal direction of the elastic sheet 17 to the trunk wearing part 20, the elastic sheet 17 is shown in FIGS. 24 and 25 on the trunk wearing part 20 Bend and hold on the inside.

The curved lower end of the substantially central portion of the elastic sheet 17 extends downward by the wearer's crotch when the wearer P wears the disposable clothing 1. That is, in the non-wearing state, the curved lower end of the elastic sheet 17 is located higher than when it is worn.

In this embodiment, as shown in FIGS. 46 and 47, the absorber 10 is arranged on the elastic sheet 17. As shown in FIG. Therefore, when the wearer wears it, the elastic sheet 17 stretches, and its contraction force presses the absorber 10 to the side of the body.

The method of attaching the elastic sheet 17 to the body part wearing part 20 is not limited to the example of FIG. 47.

Fig. 48 is a diagram showing a change in the method of attaching the elastic sheet 17 to the body part wearing part.

The elastic sheet 17 shown in FIG. 48A is joined with one end in the longitudinal direction on the inner side (body side) of the body part wearing part and at the upper part of the middle part of the joint part C1. The other end of the elastic sheet 17 in the longitudinal direction is also connected in the same way.

In this case, if the wearer P wears disposable clothing 1A, the part where the elastic sheet 17 overlaps the body part wearing part is pressed from the body part wearing part to the wearer P, so the stability of the elastic sheet 17 is improved.

In addition, one end in the longitudinal direction of the elastic sheet 17 may be joined to a joining part located inside the body portion wearing part 20 and lower than the center (the other end in the longitudinal direction of the elastic sheet 17 is also the same).

In this case, the length of the elastic sheet 17 can be shorter than that of FIGS. 47 and 48A, so the manufacturing cost can be made cheaper.

Furthermore, in the front part and the back part of the body part wearing part 20, the elastic sheet 17 can also be joined at different positions. For example, it is also possible to join the front end to the upper part of the center and the rear end to the lower part of the center to join the front end and the rear end at different positions.

In addition, in FIG. 48A, an example in which the elastic sheet 17 is joined to the inner side of the body portion wearing portion 20 has been described, but as shown in FIG. 48B, the elastic sheet 17 may be placed on the outer side of the body portion wearing portion 20. Splice. The elastic sheet 17 shown in FIG. 48B is joined with one end in the longitudinal direction on the outer side (the side opposite to the body side) of the body part wearing part 20 and the upper part of the joint part C1 from the center. The other end of the elastic sheet 17 in the longitudinal direction is also connected in the same way. In the example of FIG. 48B, since the elastic sheet 17 is located on the outer side of the body part wearing part 20, it is preferable to make the body part wearing part The height of 20 is shorter than that of Fig. 48A.

Furthermore, the form shown in FIG. 48A and the form shown in FIG. 48B may be appropriately combined. For example, it is possible to perform a combination of the form shown in FIG. 48A at the front end and the form shown in FIG. 48B at the rear end. In this way, by appropriately combining the joining form of the elastic sheet 17 to the body part wearing part 20, characteristics corresponding to the physical characteristics of the wearer can be obtained.

In FIG. 48, the example of attaching the elastic sheet 17 to the trunk|drum wearing part 20 is shown, but it is not limited to this. The elastic sheet 17 can also be attached to the waist portion 21. FIG. 49 is a diagram showing a change in the method of attaching the elastic sheet 17 to the waist portion 21. FIG.

The elastic sheet 17 shown in FIG. 49A is joined to the joining part C1 with one end in the longitudinal direction on the inner side (body side) of the waist part 21. The other end of the elastic sheet 17 in the longitudinal direction is also connected in the same way.

In this case, if the wearer P wears the disposable clothing 1A, the part where the elastic sheet 17 overlaps the waist portion 21 and the body part wearing part 20 is pressed to the wearer P, so the stability of the elastic sheet 17 is improved.

The elastic sheet 17 shown in FIG. 49B is joined to the joining part C2 with one end in the longitudinal direction on the outer side of the waist part 21 (the side opposite to the body side). The other end of the elastic sheet 17 in the longitudinal direction is also connected in the same way. In this case, in FIG. 22A, the elastic sheet 17 and the waist portion 21 can be joined by a configuration in which the arrangement of the elastic sheet 17 and the waist portion 21 are reversed.

Furthermore, the form shown in FIG. 48 and the form shown in FIG. 49 may be combined as appropriate. For example, a combination of the form shown in FIG. 48A at the front end and the form shown in FIG. 49A at the rear end can be performed. In this way, by appropriately combining the joining form of the elastic sheet 17 to the waist part 21 and the body part wearing part 20, it is possible to impart characteristics corresponding to the physical characteristics of the wearer.

As shown in FIG. 63, the elastic sheet 17 can be formed so that the body part wearing part 20 side may be wider than the crotch side. If the body part wearing part 20 side of such an elastic sheet 17 is comprised widely, the body will be pressed reliably, and the preventive effect of urine leakage etc. will be improved more.

(Effect)

Fig. 50 is a diagram illustrating the function of the disposable clothing 1A of the second embodiment. As shown in the figure, in the state where the absorbent body 10 is arranged on the elastic sheet 17, the wearer P wears disposable clothes 1A. Then, the elastic sheet 17 stretches, so the absorbent body 10 is pressed in the direction toward the body by the force of the elastic sheet 17 to contract. By the pressing force in the direction toward the body, the absorbent body 10 is in close contact with the body. In addition, if the wearer P wears disposable clothing 1A, the body wearing part 20 stretches, so the body wearing part 20 is pressed toward the body by the force of the body wearing part 20 to contract. By the pressing force toward the body, the body part wearing part 20 is in close contact with the body.

The elastic sheet 17 forms a gap S in a non-contact state with the lower part of the part joined with the trunk wearing part 20 and the trunk wearing part 20. Thereby, compared with the case where the elastic sheet 17 and the trunk wearing part 20 are integrally joined, the pressing force of the trunk wearing part 20 in the direction of the body can be made larger. Therefore, the trunk wearing part 20 can press the elastic sheet 17 more strongly in the direction toward the body.

In this way, in the disposable clothing 1A of the present embodiment, the contraction force of the elastic sheet 17 and the contraction force of the body part wearing part 20 can be combined to make the body part wearing part 20 including the elastic sheet 17 work together. The whole body is tightly attached to the body with stronger pressing force.

In addition, the disposable clothing 1 of the second embodiment can achieve the same effect as the disposable clothing 1 of the above-mentioned first embodiment.

FIG. 51 is a diagram illustrating a change in the method of attaching the absorbent body 10 in the disposable garment 1A of the second embodiment. FIG. 51A shows a state where the absorber 10 is not attached. FIG. 51B shows a state where the absorber 10 is installed. Fig. 51C shows a modified form.

As shown in FIG. 51A, in the present embodiment, the elastic sheet 17 is composed of two parts of a first sheet member 171 and a second sheet member 172.

One end F1 of the first sheet member 171 is joined to the front part of the body part wearing part 20, and the other end becomes a free end F2 when the absorber 10 is not attached.

One end G1 of the second sheet member 172 is joined to the rear part of the trunk wearing portion 20, and the other end is the free end G2 in the state where the absorber 10 is not attached, like the first sheet member 171.

The material of at least one of the first sheet member 171 and the second sheet member 172 is the same as the elastic sheet 17 described above, and is a sheet member that can expand and contract in the longitudinal direction. The so-called longitudinal direction refers to the direction extending from the front part to the back part of the body part wearing part 20 through the wearer's crotch.

The stretchable sheet member, for example, may be formed by joining a rope-shaped elastic member 17a to a sheet member such as a non-woven fabric, a moisture-permeable film, paper, etc., or it may be a rubber or urethane with its own elasticity. , Silicon sheet, stocking-like materials, knitted fabrics, etc.

Furthermore, the stretchable sheet member is not limited to the one that imparts elasticity to the entire sheet member, but also includes the one that imparts elasticity to a part of the sheet member.

In addition, the form of imparting elasticity is also the same as that of the elastic sheet 17 of the first embodiment, and the form shown in FIGS. 15 and 16 is possible.

The joining method of the first sheet member 171 and the second sheet member 172 to the body part wearing part 20 may be sewing, heat melting, heat sealing, ultrasonic bonding, gluing, and other known methods. Any one of the methods, or a combination of the same.

Furthermore, the method of attaching the first sheet member 171 and the second sheet member 172 to the body part wearing part 20 is not limited, and changes as shown in FIG. 23 and the like of the first embodiment are possible. In addition, the first sheet member 171 and the second sheet member 172 may not be fixed to the trunk wearing portion 20, or may be connected and disconnected.

The free ends F2 and G2 of the first sheet member 171 and the second sheet member 172 can be connected and detached from each other. As shown in FIG. The absorbent body 10 can be pressed to the side of the body by elastic force.

According to this embodiment, in addition to the effects of the second embodiment, there are the following effects.

By adjusting the overlapping length of the free ends F2, G2 of the first sheet member 171 and the second sheet member 172, the length of the elastic sheet 17 can be adjusted. In this way, the length of the elastic sheet 17 can be adjusted from a thin wearer to a fat wearer according to the body shape.

In the deformed form shown in FIG. 51C, one end F1 of the first sheet member 171 is joined to the front part (or rear part) of the body part wearing part 20, and the other end becomes the free end F2 when the absorber 10 is not attached.

This aspect also has the following effects in addition to the effects of the second embodiment.

By adjusting the overlapping length of the free end F2 of the elastic sheet 17 and the body part wearing part 20, the length of the elastic sheet 17 can be adjusted. In this way, the length of the elastic sheet 17 can be adjusted from a thin wearer to a fat wearer according to the body shape.

(3rd and 4th embodiment)

Fig. 52 is a diagram illustrating the third embodiment and the fourth embodiment. Fig. 52A shows the second embodiment for comparison (see Fig. 46). Fig. 52B shows the third embodiment. Fig. 52C shows the fourth embodiment. In addition, in each of FIGS. 52A to 52C, only the body part wearing part 20 is shown, and is shown in a state where the height is shortened.

In the second embodiment shown in FIG. 52A, the absorber 10 is attached to the center portion of the elastic sheet 17 on the skin side.

In this case, as described above, the attachment of the absorber 10 to the elastic sheet 17 may not be the entire surface. For example, as shown in the figure, it may be two of one end A and the other end B of the absorbent body 10, or either A or B. Furthermore, even if it is not the end part of the absorber 10, it may be a part separated by a predetermined distance from the end part like A or B. In addition, the shape of the attachment portion may be a dot shape, a line shape in the short-side direction of the absorber 10, or other shapes. In addition, the attachment position of the elastic sheet 17 to the trunk|drum wearing part 20 is shown by the code|symbol F and G in the figure.

In the third embodiment shown in FIG. 52B, one end portion (the other end B) of the absorber 10 extends to the trunk portion wearing portion 20 and is directly joined to the trunk portion wearing portion 20.

Furthermore, the joining method of the end portion of the absorbent body 10 to the body wearing portion 20 can also be any method of stitching, heat melting, heat sealing, ultrasonic joining, gluing, other known methods, or alternatively. It is a combination of others. Moreover, it may not be fixed, or it may be connected and disconnected. In addition, the attachment position of the elastic sheet 17 to the trunk|drum wearing part 20 is shown by the code|symbol F and G in the figure.

In this case, the attachment of the absorber 10 to the elastic sheet 17 may not be the entire surface. For example, the other end B of the absorber 10 is joined to the body part wearing part 20, so other parts of the absorber 10 may not be attached to the elastic sheet 17, and the end A of the absorber 10 shown in the figure may also be attached于flexible sheet 17. Also, in the case of installation, even if it is not one end A It is the other part of the absorbent body 10. In addition, the attachment shape may be a dot shape, a linear shape in the short-side direction of the absorber 10, or other shapes.

In the fourth embodiment shown in FIG. 52C, both ends of the absorber 10 extend to the trunk wearing portion 20 and are directly joined to the trunk wearing portion 20.

In this case, the absorber 10 and the elastic sheet 17 are also not joined.

(Fifth, sixth, and seventh embodiment)

Fig. 53 is a diagram illustrating the fifth embodiment, the sixth embodiment, and the seventh embodiment. Fig. 53A shows the fifth embodiment of the present invention. Fig. 53B shows the sixth embodiment of the present invention. Fig. 53C shows the seventh embodiment of the present invention. In addition, in each of FIGS. 53A to 53C, only the body part wearing part 20 is shown, and the figure is shown in a state in which the height is shortened.

In the fifth embodiment, the sixth embodiment, and the seventh embodiment, the difference from the first embodiment is that the inner sheet 18 is provided above the elastic sheet 17 (on the body side). The inner sheet 18 is a sheet member composed of paper, non-woven fabric, and film. As the inner sheet 18, it is preferable to use a sheet with weaker stretchability than the non-stretch or elastic sheet 17, but it is not limited to this, and it may be equivalent to or more than that of the elastic sheet 17. Stretchable sheet.

In the fifth embodiment shown in FIG. 53A, both ends of the inner sheet 18 are joined to the trunk wearing portion 20.

The joining method can be any method of stitching, heat melting, heat sealing, ultrasonic joining, gluing, and other well-known methods, or a combination thereof. Moreover, it may not be fixed, or it may be connected and disconnected.

In the sixth embodiment shown in FIG. 53B, only one end of the inner sheet 18 is joined to the trunk wearing portion 20. In the seventh embodiment shown in FIG. 53C, the inner sheet 18 and FIG. 53B Similarly, only one end is joined to the trunk wearing part 20, and one end of the absorbent body 10 is also joined to the trunk wearing part 20.

In the fifth, sixth, and seventh embodiments, the absorber 10 is attached to the inner sheet 18.

According to the above-mentioned embodiment, when the inner sheet 18 is non-stretchable, or when the stretchability is weaker than that of the elastic sheet 17, wrinkles are not generated compared to the elastic sheet 17. Therefore, even when the wearer himself attaches the absorber 10 to the inner sheet 18, it is also possible to attach the absorber 10 even when the absorber 10 is attached to the inner sheet 18 in the manufacturing process. Since it is on the elastic sheet 17, it is easy to install.

On the other hand, when the elasticity of the inner sheet 18 is stronger than in the case described above, when the absorber 10 is attached to the elastic sheet 17, the inner sheet 18 must be expanded or the like.

Furthermore, since the absorber 10 is not directly attached to the elastic sheet 17, the presence of the absorber 10 does not affect the elastic force of the elastic sheet 17. As a result, when the wearer is wearing it, the elastic force of the elastic sheet 17 presses the absorbent body 10 through the inner sheet 18 from right down to the wearer's body direction, and the adhesion between the absorbent body 10 and the wearer is improved. , Can prevent leakage of urine. In addition, a suture hole (not shown) may be provided in the inner sheet 18 as necessary. If a stitch hole is provided in the elastic sheet 17 or the inner sheet 18, the elastic sheet 17 or the inner sheet 18 can be cut from the stitch hole when the wearer wants to relax the pressing force when wearing it. Adjust the pressure on the body.

Furthermore, when the inner sheet 18 is a stretchable sheet, combined with the stretch of the elastic sheet 17, the pressing force on the body can be increased.

In addition, in the fifth, sixth, and seventh embodiments, the inner sheet 18 is the same as the elastic sheet 17 shown in FIG. 51, and may be composed of two parts of the first inner sheet and the second inner sheet.

In this case, as in the example of FIG. 51, the material of at least one of the first inner sheet and the second inner sheet is the same as the above-mentioned elastic sheet 17, and it may be a sheet member that can stretch in the longitudinal direction. . The so-called longitudinal direction refers to the direction extending from the front part to the back part of the body part wearing part 20 through the wearer's crotch.

The stretchable sheet member, for example, may be formed by joining a rope-shaped elastic member 17a to a sheet member such as a non-woven fabric, a moisture-permeable film, paper, etc., or it may be a rubber or urethane with its own elasticity. Made of elastic members, silicon elastic members, silicon sheets, stocking-like materials, knitted fabrics, etc.

Furthermore, the stretchable sheet member is not limited to imparting elasticity to the entire sheet member, and includes imparting elasticity to a part of the sheet member.

In addition, the form of imparting elasticity is also the same as that of the elastic sheet 17 of the first embodiment, and the form shown in FIGS. 11 and 12 is possible.

In addition, as shown in FIGS. 53A and 53B, the joint points of the inner sheet 18 of the absorbent body 10 of the fifth and sixth embodiments are one end A and the other end B of the absorbent body 10.

As shown in FIG. 53C, the junction point of the absorber 10 to the inner sheet 18 of the seventh embodiment is one end A of the absorber 10. As shown in FIG. In addition, the junction point of the absorber 10 to the trunk wearing part 20 is the other end B of the absorber 10.

The attachment of the absorber 10 to the inner sheet 18 is preferably not the entire surface. In the case of FIG. 53A and FIG. 53B, it can be two places of one end A and the other end B of the absorbent body 10, and It may be either A or B. Furthermore, even if it is not the edge part of the absorber 10, it may be a part separated from the edge part by only a predetermined distance.

In the case of FIG. 53C, since the other end B of the absorbent body 10 is joined to the body part wearing part 20A, other parts of the absorbent body 10 may not be attached to the inner sheet 18, and the absorbent body 10 shown in the figure One end A can also be installed on the inner sheet 18. In addition, in the case of installation, even if it is not one end A, it may be another part of the absorber 10. In addition, the attachment shape may be a dot shape, a linear shape in the short-side direction of the absorber 10, or other shapes.

The joining point of the inner sheet 18 to the trunk wearing part 20 is indicated by H and I in FIG. 53A, and is indicated by I in FIGS. 53B and 53C. In addition, the joining point of the elastic sheet 17 to the trunk wearing part 20 is indicated by F and G in FIGS. 53A to 53C.

Example

Hereinafter, specific examples of the stretchable composite sheet used in the present invention are listed to explain the present invention in more detail.

(Example 1)

As the air-permeable sheet, spunbonded non-woven fabric (weight per unit area 10g/m ² ) is used, and as the liquid diffusing fibrous sheet, paper made of 100% pulp (paper sheet for toilet paper: weight per unit area 18g/m ² ) It is used as it is without printing. As a linear elastomer, a urethane rubber with a diameter of 620 cents is used. Between two pieces of non-woven fabrics, sandwich paper and urethane rubber stretched 2.6 times, ^{and then use hot melt adhesive (the coating amount of hot melt adhesive is 1.2g/m 2} ) and then implement The sheet material with a total basis weight of 149.3 g/m ² obtained by the embossing process was set as Example 1. Furthermore, the total unit area weight of the sheet material is the value after the sheet material shrinks due to the restoring force of the stretched urethane rubber.

(Comparative example 1)

Using the same non-woven fabric and urethane rubber as in Example 1, the urethane rubber that stretched 2.6 times was inserted between the non-woven fabrics by hot-melt adhesive, and then followed (application of hot-melt adhesive) After 1.2 g/m ² ), the sheet material obtained by embossing was set as Comparative Example 1. The total weight per unit area of the sheet material was 92.3 g/m ² .

(Comparative example 2)

The non-woven fabrics on the front and back sides were spunbonded non-woven fabrics, and a conventional sheet material of urethane rubber with a rubber diameter of 620 tex was interposed between the non-woven fabrics as Comparative Example 2. The total weight per unit area of the sheet material is 123.2 g/m ² .

(Comparative example 3)

The non-woven fabrics on the front and back sides were heat-bonded non-woven fabrics, and a conventional sheet material of urethane rubber with a rubber diameter of 620 tex was interposed between the non-woven fabrics as Comparative Example 3. The total weight per unit area of the sheet material was 144.9 g/m ² .

(Comparative Example 4)

The non-woven fabrics on the front and back sides were heat-bonded non-woven fabrics, and the conventional sheet material of urethane rubber with a rubber diameter of 620 tex was interposed between the non-woven fabrics as Comparative Example 4. The total weight per unit area of the sheet material was 147.8 g/m ² .

(Comparative Example 5)

The non-woven fabrics on the front and back sides were heat-bonded non-woven fabrics, and a conventional sheet material of urethane rubber with a rubber diameter of 620 tex was interposed between the non-woven fabrics as Comparative Example 5. The total weight per unit area of the sheet material is 143 g/m ² .

First, the evapotranspiration and moisture permeability of the sheet materials of such Example 1 and Comparative Examples 1 to 5 were evaluated.

First, the evapotranspiration system was subjected to an evapotranspiration (II) test (BOKEN standard BQEA028) to comprehensively evaluate both water absorption and quick-drying.

For the sheet materials of Example 1 and Comparative Examples 1 to 5, test pieces with a diameter of about 9 cm were made, and the mass (W) of each test piece and petri dish was measured. Next, 0.1 ml of water was dropped on the petri dish, a test piece was placed on the petri dish, and the mass was measured (W0). Place it in a standard state (20°C, humidity 65%RH), and measure the mass (Wt) every time a predetermined time (5 minutes, 10 minutes, and below every 10 minutes until 60 minutes) has passed. Based on the measured masses W, W0, and Wt, the following formula (1) is used to calculate the evapotranspiration rate (%) per predetermined time.

Evapotranspiration rate (%)=((W0-Wt)/(W0-W))×100‧‧‧‧(1)

The results are shown in Table 1.

According to the results of the evapotranspiration rate shown in Table 1, it is clear that in Comparative Examples 3 to 5, the evapotranspiration rate was less than 20% even after 60 minutes. In Comparative Examples 1 and 2, the evapotranspiration rate did not reach 20 minutes after 20 minutes. 20%, the evapotranspiration rate is 40% or less even after 60 minutes. On the other hand, in Example 1, the evapotranspiration rate exceeds 20% after 10 minutes, and the evapotranspiration rate exceeds 40% after 20 minutes. Then, after 30 minutes The post evapotranspiration rate exceeds 60%, the evapotranspiration rate exceeds 75% after 40 minutes, the evapotranspiration rate exceeds 85% after 50 minutes, and the evapotranspiration rate exceeds 90% after 60 minutes.

Furthermore, in the BOKEN standard BQEA028, as an evaluation standard, it can be said that the evapotranspiration rate 20 minutes after the start of the test is used in sports applications, preferably in fabrics. 50% or more, 40% or more in woven fabrics. In the case of general use, it is preferably more than 40% in woven fabrics and 30% or more in woven fabrics.

Therefore, the sheet material of Example 1 can obtain an evapotranspiration rate of more than 40%, so it can be said that it can be worn comfortably for sports or general purposes.

Based on the above, it can be seen that the disposable clothing of the present invention using the sheet material of Example 1 has extremely high evapotranspiration.

Next, the moisture permeability was evaluated by the A-1 method (calcium chloride method) of JIS-L1099 (2012) to obtain the moisture permeability (g/m ² ‧h).

Furthermore, the moisture permeability is defined as the value obtained by converting the mass (g) of water vapor passing through the fiber product into the average 1m ² ×1 hour of the fiber product in the specified temperature and humidity.

According to JISL0105 6.3 (cloth-shaped sample and its test piece), test pieces were collected from the sheet materials of Example 1 and Comparative Examples 1 to 5.

Prepare the moisture permeable cup, constant temperature, constant humidity device, circular plate, and hygroscopic agent specified in the calcium chloride method and conduct the experiment.

First, add about 33g of moisture absorbent to the moisture permeable cup preheated to about 40℃. After applying vibration to the moisture permeable cup to make it even, flatten the surface with a spatula. Use a circular plate to combine the moisture absorbent with the test piece. Adjust the distance between the bottom surface to 3mm.

Next, with respect to the sheet materials of Example 1 and Comparative Examples 1 to 5, three test pieces with a diameter of approximately 70 mm were taken in accordance with JIS L0105 6.3 (cloth-like samples and test pieces).

Place the surface of each test piece so that it is concentric with the vapor-permeable cup toward the side of the moisture absorbent, install washers and rings in sequence, and fix them with a wing nut, then seal the mounting side with vinyl adhesive tape to form a test body . Place the test body in a constant temperature and humidity device with a temperature of 40°C±2°C and a humidity of (90±5)%RH at a position where the wind speed at the upper part of about 10mm does not exceed 0.8m/s on the test piece. After 1 hour, the test body was taken out, and the mass (a1) was immediately measured until it reached 1 mg. After the measurement, the test body was placed in the same position of the constant temperature and humidity device again, and the test body was taken out one hour later, and the mass (a2) was immediately measured until 1 mg. Based on the measured masses a1 and a2, the following formula (2) is used to calculate the moisture permeability PA1 (g/m ² ‧h).

Water permeability PA1(g/m ² ‧h)=(a2-a1)/SA1‧‧‧‧(2)

In formula (2), a2-a1 refers to the average one-hour mass change (g/h) of the test body, and SA1 refers to the moisture permeability area (m ² ).

The test result is expressed as the value obtained by rounding the first decimal place according to the rule of JISZ8401 (rounding method) of the average of 3 times. The results obtained are shown in Table 2.

According to the results of the moisture permeability shown in Table 2, it is clear that in Comparative Examples 2, 3, and 5, the moisture permeability is ^{less than 500g/m 2} ‧h, and in Comparative Example 1, it is 563g/m ² ‧h In Comparative Example 4, the moisture permeability is 526g/m ² ‧h. On the other hand, in Example 1, it was 564 g/m ² ‧h, which was higher than the comparative example.

Based on the above, it can be seen that the functional fabric material of the present invention has high stability and good moisture permeability.

Next, regarding Example 1 and Comparative Examples 1 to 5, the evaluation results of moisture permeability and the evaluation results of evapotranspiration after 20 minutes and 60 minutes are shown in Table 3.

According to the evaluation results of evapotranspiration and moisture permeability shown in Table 3, it is clear that the functional fabric material of the present invention of Example 1 is compared with the functional fabric materials of Comparative Examples 1 to 5. It is excellent, with high evapotranspiration rate and moisture permeability.

Based on the above, the effect of the functional fabric material for the disposable product and the disposable structure product of the present invention is clear.

Furthermore, of course, the present invention is not limited to the embodiments described above, and includes all embodiments that can achieve the purpose of the invention.

Secondly, test the cold contact feeling (cold feeling) and wet contact cold temperature feeling (sticky feeling when sweating) between the sheet material with paper interposed between the non-woven fabrics and the sheet material without paper interposed between the non-woven fabrics .

(Examples 2~5)

The same non-woven fabric, paper, hot melt adhesive, and urethane rubber adjustment sheet materials as in Example 1 were used. The paper used in Examples 2 and 3 was embossed with the number of times shown in Table 4 using a pair of flat rollers. The weight per unit area of the paper used, the total weight per unit area of the hot melt adhesive The total unit area weight of the material and the sheet material are shown in Table 4. For these sheet materials, the cold contact feeling and the wet contact warm feeling were measured according to the following methods. Table 5 shows the results of the values of the cold contact feeling and the wet contact cold temperature feeling.

Cold contact feeling (W/m ² ‧K): Cold contact feeling refers to the size of the cool feeling when wearing and the amount of heat movement when wearing. Therefore, the cold sensation can be said to be cool when the heat moves more. That is, as the sample, it can be said that the one having a larger contact coldness value is excellent. The cold contact sensation was measured using a precise and rapid thermal property measuring device (KES-F7THERMOLABOII manufactured by Kato Technology Co., Ltd.) according to the following method. Place the test piece (6cm×6cm) cut from the sheet material on the bottom plate at 20°C. Heat the hot plate with precision thermal sensor to 40°C, place the hot plate on the test piece at 20°C, and calculate the cold contact value (qmax) based on the heat release behavior measured by the thermal sensor of the hot plate.

Wet-contact cold-temperature sensation (W/m ² ‧K): The wet-contact cold-temperature sensation is expressed by the amount of heat movement when sweating, that is, when wet. Therefore, as a sample, it can be said that the one with a small wet-contact cold-temperature sensation value has no stickiness and is excellent. The sensation of cold contact when wet is measured using a precise and rapid thermal property measuring device (KES-F7THERMOLABOII manufactured by Kato Technology Co., Ltd.) according to the following method.

The test piece (6cm×6cm) cut from the sheet material was placed on the bottom plate at 20°C by ^{absorbing 80 g/m 2 of water and feeding the water.} Heat the hot plate with precision thermal sensor to 40°C, place the hot plate on the test piece at 20°C, and calculate the wet contact cold temperature sensitivity value (wet) based on the heat release behavior measured by the thermal sensor of the hot plate -qmax).

(Comparative Example 6)

Use the same sheet material as in Comparative Example 2, and compare it in the same way as in Examples 2 to 5. Tests are performed on contact with cold sensation and wet contact with cold temperature sensation. The results are shown in Table 5.

(Comparative Example 7)

Using the same sheet material as in Comparative Example 4, the cold contact feeling and the wet contact cold temperature feeling were tested in the same manner as in Examples 2 to 5. The results are shown in Table 5.

(Comparative Example 8)

Using the same sheet material as in Comparative Example 3, the cold contact feeling and the wet contact cold temperature feeling were tested in the same manner as in Examples 2 to 5. The results are shown in Table 5.

(Comparative Example 9)

Using the same sheet material as in Comparative Example 5, the cold contact feeling and the wet contact cold temperature feeling were tested in the same manner as in Examples 2 to 5. The results are shown in Table 5.

From the results shown in Table 5, it is clear that in Examples 2 to 5, the values are equal to or higher than those of Comparative Examples 6 to 9, which indicates that the contact cold sensation is excellent. In addition, in Examples 2 to 5, the sensation of cold contact temperature when wet is 100 or less. In contrast, Comparative Examples 6 to 9 have values of 100 or more. Therefore, it can be said that the sheet materials of Examples 2 to 5 are comparable to those in comparison. Compared with the sheet materials of Examples 6-9, the sticky feeling is less when sweating. As a result, it can be seen that both the cold contact feeling and the cold temperature feeling in contact when wet are excellent.
