Description

  The present invention relates to sanitary shorts that have an ability to absorb fluid discharged from the body, have excellent fit around the waist and legs, and can be manufactured at low cost.

Conventionally, sanitary shorts used for fixing an absorbent article such as a sanitary napkin or an incontinence pad and fitting the absorbent article to a wearer's body are known.
For example, Patent Document 1 describes sanitary shorts which are made of a stretchable nonwoven fabric having a specific structure and whose basis weight is within a specific range.

JP 2000-60900 A

  However, this sanitary short is used by fixing a sanitary napkin, an incontinence pad or the like, and does not itself have an absorption performance. Therefore, if menstrual blood or urine leaks from these due to a sanitary napkin or incontinence pad misalignment, the liquid leaks easily from the shorts, causing the clothes to become dirty.

  In addition, a member different from the stretchable nonwoven fabric is attached to the opening peripheral portion of the waist opening and the leg opening in the sanitary shorts described in Patent Document 1, and the member itself and the attaching process thereof are necessary. For this reason, it is difficult to manufacture shorts at low cost. On the other hand, when another member for enhancing the stretchability is not attached to each opening, sufficient fit cannot be obtained for each opening.

JP 2000-60900 A

  Accordingly, an object of the present invention is to provide sanitary shorts that have an ability to absorb fluid discharged from the body, have excellent fit around the waist and around the legs, and can be manufactured at low cost.

  The present invention is a sanitary short having a front body, a back body, and a crotch portion positioned between the two, and a waist opening and a pair of leg openings formed therein, and an absorption layer is provided on the crotch And at least a peripheral region of each of the waist opening and the leg opening is formed of an elastic sheet, and a region having a predetermined width from the edge of the elastic sheet in each opening is a circumferential direction of each opening. This object is achieved by providing sanitary shorts which are folded and joined so as to increase the stretchability.

  ADVANTAGE OF THE INVENTION According to this invention, the sanitary shorts which have the capability of absorbing the discharge | emission liquid from a body, are excellent in the fit property of a waist periphery and a leg periphery, and can be manufactured cheaply can be provided.

The present invention will be described below based on preferred embodiments with reference to the drawings.
As shown in FIGS. 1 and 2, an incontinence shorts 1 according to an embodiment of the present invention includes a front body 2 disposed on the wearer's abdomen, a back body 3 disposed on the wearer's back, And a crotch part 4 positioned between the front body 2 and the backward body 3, and both side edges of the front body 2 and both side edges of the backside body 3 are joined together by sewing together to form a waist opening 5. A pair of leg openings 6 and 6 are formed.
The incontinence shorts 1 is provided with an absorption layer 7 and a leak-proof layer 8 to be described later on a shorts body 10 composed of elastic sheets 21, 31 and 41. The shorts body 10 is in the form of a shorts having a waist opening 5 and a pair of leg openings 6, 6.

  The shorts main body 10 is composed of elastic sheets 21, 31, and 41, each of which forms the front body 2, the back body 3, and the crotch part 4, and is on the skin facing surface side of the part that forms the crotch part 4. As shown in FIG. 3, an absorption layer 7 is provided, and the non-skin facing surface side of the absorption layer 7, specifically, between the absorption layer 7 and the elastic sheet 41, is liquid-impermeable. In addition, a moisture-permeable leak-proof layer 8 is provided. The skin facing surface and the non-skin facing surface are a surface facing the wearer's skin side and a surface facing the opposite side of each member, and are provided on the skin facing surface side (or non-skin facing surface side). The expression “being” includes a case where another member is interposed between the skin facing surface (or the non-skin facing surface).

As a material for forming the absorbent layer 7, various known materials conventionally used as absorbents such as sanitary napkins and disposable diapers, such as fiber webs or nonwoven fabrics or those having a superabsorbent polymer held thereon, may be used. However, the absorbent layer 7 may be composed of a sheet 71 containing hydrophilic fibers from the viewpoints of washing resistance, drying properties, feeling of wearing, etc., when washing and making shorts that can be used repeatedly several times. preferable.
The sheet 71 constituting the absorbent layer 7 is a sheet containing hydrophilic fibers. Sheets containing hydrophilic fibers include knitted fabrics, woven fabrics, and nonwoven fabrics produced by various known production methods, but do not include paper.

  A preferred sheet 71 is a knitted fabric or a woven fabric, and a particularly preferred sheet 71 is a knitted fabric. The sheet 71 preferable as the nonwoven fabric maintains the shape of the nonwoven fabric only by entanglement of the constituent fibers, and is, for example, a spunlace nonwoven fabric, a needle punched nonwoven fabric, a spunbonded nonwoven fabric, or the like. By using such a nonwoven fabric for the absorbent layer 7, it is possible to reduce the rigidity of the crotch portion of the shorts 1 while maintaining the absorption capacity, and to improve the wearing feeling during wearing. However, a nonwoven fabric such as a chemical bond or a thermal bond can be used as the sheet 71 constituting the absorption layer.

  The hydrophilic fiber contained in the sheet 71 is to impart liquid absorption performance to the absorbent layer 7. As the hydrophilic fiber, a hydrophobic synthetic fiber such as polyethylene, polyester, polypropylene, etc. is hydrophilized with an activator or the like. Various known hydrophilic fibers such as those subjected to the above are used, but in the case of obtaining shorts that can be reused by washing after use, the sheet 71 is hydrophilic from the viewpoint of preventing a decrease in absorption performance due to washing. It is preferable to contain cellulosic fibers such as rayon fiber, cotton fiber and hemp as the fiber. Further, when the sheet 71 is a non-woven fabric, the strength between the fibers constituting the fabric is weaker than that of the woven fabric or the knitted fabric. Therefore, the hydrophilic fiber should be a continuous filament or a fiber having a fiber length of 30 mm or more. It is preferable from the viewpoint of washability.

The content of hydrophilic fibers in the sheet 71 is preferably 50 to 100%, particularly preferably 80 to 100%.
The sheet 71 may include fibers other than hydrophilic fibers, and examples of fibers other than hydrophilic fibers include hydrophobic synthetic fibers such as acrylic fiber, polyethylene, polyester, and polypropylene. It is preferable to mix hydrophobic synthetic fibers because washing resistance can be improved. When the hydrophobic synthetic fiber is contained, the content of the synthetic fiber in the sheet 71 containing the hydrophilic fiber is preferably 0 to 50%, particularly preferably 0 to 20%.

  In the incontinence shorts 1 of the present embodiment, the peripheral regions of the waist opening 5 and the pair of leg openings 6, 6 are formed from the elastic sheets 21, 31, 41 described above.

As shown in FIGS. 2 and 4, the elastic sheets 21 and 31 in the waist opening 5 are joined to the opposite portions by folding regions 23 and 33 having predetermined widths from the end edges 22 and 32 thereof. Thereby, the elasticity of the circumferential direction P of the waist opening 5 is enhanced.
As shown in FIGS. 2 and 5, the elastic sheet 31 in each leg opening 6, 6 is also joined to the opposing part by folding a region 37 of a predetermined width from each end edge 36. Thereby, the elasticity of each leg opening 6 in the circumferential direction Q is enhanced.

  In this specification, “stretchability is increased (or increased)” means a state in which the regions 33 and 37 having a predetermined width are folded and joined from the edge of the elastic sheet 31 in each opening [FIG. 4B and FIG. 5B], the stretchability in the circumferential directions P and Q of the opening is the state in which the elastic sheet 31 is not folded back [same as the state before folding, FIG. 4A and FIG. It means that it is higher (higher) than the stretchability in the same direction P, Q.

  Whether or not the stretchability is increased is determined by, for example, extracting a region having a predetermined width from the edge of the sheet before folding and stretching it in the longitudinal direction, and a predetermined width from the folding line after folding. A region with a predetermined width is larger than the folded line after folding, by cutting out the region (with the same width as the cut-out width before folding) and comparing it with the extension stress when it is stretched under the same conditions. In this case, it is determined that “stretchability is increased (or increased)”.

  In addition, it is preferable that the peripheral region of each opening is formed of an elastic sheet over the entire area in the circumferential direction of each opening, and the stretchability is enhanced in the entire area in the circumferential direction. The whole or only part may be formed from an elastic sheet, and the stretchability may be enhanced only in a part in the circumferential direction.

  The folding width L1 (see FIG. 4) of the elastic sheets 21 and 31 in the waist opening 5 is preferably 3 to 30 mm, particularly 5 to 25 mm from the viewpoint of reliably improving the fit around the waist. The folding width L2 (see FIG. 5) of the elastic sheet 31 in the portions 6 and 6 is preferably 3 to 10 mm, particularly 5 to 8 mm, from the viewpoint of reliably improving the fit around the legs.

Moreover, it is preferable that the direction which folds an elastic sheet is the skin opposing surface side (inner surface side) of shorts rather than the non-skin opposing surface side (outer surface side) of shorts. There is a step in the thickness between the part where the folded part is laminated and the two parts are not laminated, and the other part where the folded part is not laminated. Is obtained.
In addition, as a joining means for joining the folded portion to the facing portion (other portion of the elastic sheet that is opposed by folding), a means that hardly restricts the elastic contraction force is preferable, and the contraction force is maintained and easy to process. From the viewpoint of this, suturing is particularly preferable. Bonding with an adhesive is not preferable because it tends to limit the shrinkage force. Reference numerals 51 and 61 in FIGS. 1, 4 and 5 indicate threads used for sewing.

  The elastic sheets 21, 31, and 41 used in the present embodiment are all inferior in stretchability in the high stretch direction in the plane, in the direction perpendicular to the high stretch direction, and in the stretch direction. More specifically, as shown in FIG. 4, the sheet includes a sheet base 34 and a plurality of elastic members 35 fixed to the sheet base 34. The elastic members 35 are arranged in parallel to each other and have the same stretching force in each orientation direction. The high expansion / contraction direction of the elastic sheet 31 (the same applies to 21 and 41) is the orientation direction of the elastic member 35, and the low expansion / contraction direction is a direction orthogonal to the alignment direction of the elastic member 35.

  The elastic member 35 forms a plurality of parallel linear stretchable parts (linear or narrow areas having stretchability) extending in one direction on each elastic sheet. The linear stretchable parts are formed in parallel with each other at a predetermined interval (for example, 3 to 10 mm, preferably equal intervals), and the linear stretchable parts do not have stretchability or stretch more than the linear stretchable parts. It is a low stretch region inferior in nature.

  As the elastic sheet, a stretchable nonwoven fabric in which the nonwoven fiber layer is stitched and stitched with a knitting yarn containing stretchable fibers can be preferably used. In this case, the non-woven fiber layer is a base material sheet, and the mesh thread containing stretchable fibers is an elastic member. The elastic member does not need to be arranged substantially linearly when viewed three-dimensionally, and includes one in which a linear stretchable part is formed in one direction by stitch stitching. In this case, the direction in which the linear stretchable part extends is the orientation direction of the elastic member.

  As an elastic nonwoven fabric in which a nonwoven fiber layer is stitched and stitched with a knitting yarn containing elastic fibers, for example, “Nonwoven fiber layer is stitched and stitched with a knitting yarn containing elastic fibers”. Can be used.

  The non-woven fiber layer is formed by entanglement of constituent fibers, and polyester, nylon, polypropylene, vinylon, cupra, acrylic, rayon, cotton or the like can be used as the constituent fiber. The constituent fibers may be all the same type or different types of fibers, and the constituent fibers may be either filament yarns or short fibers.

The stretchable fiber is a composite-spun crimped fiber by a combination of a low-viscosity polymer and a high-viscosity polymer, a composite-spun crimped fiber by a combination of different polymers, a composite-spun crimped fiber by a bimetal structure, or the like by crimping This refers to high-processed yarns, highly elastic rubber yarns (latex), polyurethane elastic yarns, and the like.
The knitting yarn includes such a stretchable fiber. The knitting yarn may be used as a bare yarn, or may be covered with other natural fibers or synthetic fibers. Also good.

  It is also preferable to knit the knitting yarn containing elastic fibers and other fibers. As the knitting yarn, synthetic fiber filament yarn, coated elastic yarn and the like can be preferably used. The content of the knitted yarn in the entire nonwoven fabric is preferably in the range of 30% to 65%. In the present specification, “%” is by weight unless otherwise specified.

  The knitted structure of the elastic nonwoven fabric is formed by knitting elastic fibers and knitting yarn using a plurality of sheaths, for example, two sheaths (2 bars) or three sheaths (3 bars). Is preferred. Specifically, a chain knitting having a large elongation in the vertical direction, a 1-2 needle swing knitting in which the elongation in the horizontal direction is obtained, a satin knitting or an atlas knitting in which the elongation in both the vertical and horizontal directions can be obtained, and the like can be adopted.

  The stitch stitching means a state in which the non-woven fiber layer is sandwiched between the stretchable fibers as the front yarn (front bar or L1) and the knitting yarn as the back yarn (backbar or L2). For stitch stitching, for example, a commercially available Russell warp knitting machine can be used. As the nonwoven fiber layer before stitch stitching, a spunlace nonwoven fabric, a needle punched nonwoven fabric, a spunbonded nonwoven fabric, or the like can be used.

The stretchable nonwoven fabric uses, for example, a polyester filament yarn having a single fiber denier of 0.1 denier or more and 3.5 denier or less as a constituent fiber, and has a spunbond type basis weight (weight per unit area) of 15 g / m ² or more. It can be obtained by obtaining a raw nonwoven fabric in a range of 50 g / m ² or less and stitching the raw nonwoven fabric with a knitting yarn containing stretchable fibers and a knitting yarn.

  In the incontinence shorts 1 of the present embodiment, the elastic sheets 21, 31, 41 forming the front body 2, the back body 3, and the crotch part 4 are all short in the direction of high expansion and contraction (orientation direction of the elastic member). In the width direction (the left-right direction in FIG. 2).

  That is, the elastic sheets 21 and 31 forming the peripheral region of the waist opening 5 are arranged so that the respective high stretch directions (orientation directions of the elastic members) coincide with the width directions of the front body 2 and the back body 3, respectively. The regions 23 and 33 having a predetermined width folded back at the waist opening 5 are folded in a direction perpendicular to the width direction of the front body 2 and the back body 3. Thereby, the elasticity of the circumferential direction of the opening peripheral part of the waist opening part 5 can be improved efficiently.

  The elastic sheets 21, 31, and 41 that form the peripheral region of the leg opening 6 are arranged in the front body 2 and the back body 3 so that the respective high stretch directions (orientation directions of the elastic members) are the front body 2. The region 37 having a predetermined width that is arranged so as to coincide with the width direction of each of the back body 3 and folded back at the leg opening 6 has a high expansion / contraction direction in the width of each of the front body 2 and the back body 3. It is folded so as not to coincide with either the direction or the direction orthogonal to the width direction. Thereby, the elasticity of the circumferential direction of the opening peripheral part of the leg opening part 6 can be improved efficiently.

The low expansion / contraction direction of the elastic sheet having a high expansion / contraction direction and a low expansion / contraction direction includes both a case where the elastic sheet does not have elasticity and a case where the elastic sheet has elasticity but its degree is smaller than that of the high expansion / contraction direction. Moreover, the high expansion / contraction direction should just be higher in elasticity than the low expansion / contraction direction.
The elastic sheets 21, 31, 41, particularly the elastic sheet 31 that forms the back body 3, preferably have stretchability in the longitudinal direction of the shorts (the vertical direction in FIG. 2). In particular, when the elastic sheet expands and contracts in the shorts longitudinal direction, the elastic sheet follows the vertical extension of the buttocks skin at the sitting position (when the posture changes from the standing position to the sitting position). It is possible to effectively prevent the slippage at the end of the waist opening.

  Further, the regions 23 and 33 of the predetermined width of the elastic sheets 21 and 31 folded back at the waist opening 5 are formed of the elastic member 35a in the regions 23 and 33 and the region as shown in FIG. Are folded back so as to be alternately arranged in a direction perpendicular to the width direction P of each of the front body 2 and the back body 3 (vertical direction in FIG. 4). With such a configuration, since the stretching force in the circumferential direction of the opening in each part in the direction orthogonal to the circumferential direction of the waist opening is equalized, local excessive tightening on the wearer can be prevented. .

  In the front body 2 and the back body 3, the elastic sheets 21 and 31 that form the peripheral region of each leg opening 6 have a high stretch direction (orientation direction of the elastic member) of the sheet in the folded portion and the portions other than the folded portion. The angle α (see FIG. 5 (b)) formed with the high expansion / contraction direction (orientation direction of the elastic member) of the sheet is 30 ° or more and less than 90 °, particularly 45 ° or more and less than 80 °. From the viewpoint of obtaining excellent fit that can be followed well.

  In the incontinence shorts 1 of the present embodiment, as shown in FIG. 2, in the state where the sanitary shorts are developed, the longitudinal ends 72 and 73 of the absorbent layer 7 are respectively the longitudinal ends of the leg openings. It is located in the center part side of a shorts longitudinal direction rather than the position of 62,63. Although the absorption layer 7 becomes a factor which inhibits shrinkage | contraction of a leg opening part, with such a structure, the area | region which can shrink | contract in a leg opening part can be ensured reliably, and the fitting property excellent in the leg periphery is obtained. be able to.

  The total length L3 (see FIG. 2) of the absorbent layer 7 has a ratio (L3 / L4) of 0.5 to 0.9 with respect to the distance L4 (see FIG. 2) between both ends 62 and 63 in the longitudinal direction of the leg opening. In particular, the value of 0.6 to 0.8 is preferable from the viewpoint of achieving both the leak-proof performance and the fit around the legs. The total length L3 of the absorbent layer 7 is 120 to 300 mm, and the minimum width W (see FIG. 3) in the crotch part 4 of the absorbent layer 7 is 80 to 110 mm. To preferred. Moreover, it is preferable from a viewpoint of the improvement of fit property and comfort that the absorption layer 7 is a shape with which the center part was constricted, especially a heel shape.

The leak-proof layer 8 in this embodiment is formed by disposing a liquid-impermeable and moisture-permeable leak-proof sheet 81 on the skin facing surface side of the elastic sheet 41 constituting the crotch part 4.
As the leak-proof sheet 81, various known moisture-permeable sheets conventionally used as a back sheet such as a disposable diaper can be used. For example, a diffusivity such as a microporous film, polyurethane or polyester film is used. Nonporous moisture permeable film and the like. The microporous film is formed by melt-kneading a hydrophobic thermoplastic resin and a fine inorganic filler made of calcium carbonate or the like, or an organic polymer incompatible with the thermoplastic resin, and the like. Is obtained by uniaxial or biaxial stretching.
The moisture permeability of the leak-proof sheet 81 is preferably 1.0 g / (100 cm ² · hr) or more as measured by JIS Z 0208.

The elastic sheet 41, the absorbent layer 7 (sheet 71), and the leak-proof sheet 81 in the present embodiment have the same shape in plan view, and the front and rear ends 42 and 43 and the side edges 44 and 44 are stitched in the thickness direction. The front and rear ends 42, 43 are also stitched to the elastic sheets 21, 31 of the front body 2 and the back body 3. That is, the absorbent layer 7 (sheet 71) is joined to the shorts body 10 only at the stitched portion formed at the peripheral edge thereof.
Since it has such a structure, the discomfort in the crotch part can be reduced and an excellent wearing feeling can be achieved. In particular, compared with the case where the entire or part of the absorbent layer 7 is bonded to the shorts body with an adhesive or the like, the effect of reducing the sense of incongruity is extremely high.

  The incontinence shorts 1 of the present embodiment has improved elasticity in the circumferential direction of the waist opening and the leg opening by folding and joining the elastic sheet, so that each elastic member is attached with another elastic member. Compared with the case where stretchability is imparted to the opening, it is possible to simplify the manufacturing process, reduce the number of members used, reduce the manufacturing cost, and the like.

  In addition, since an elastic sheet including a sheet base material 34 and a plurality of elastic members 35 fixed to the sheet base material 34 is used as the elastic sheet, the sheet base material 34 is fine due to the contraction of the elastic member 35. Forms unevenness and does not adhere to the wearer's skin when worn. Thereby, troubles such as stuffiness and rash due to excessive contact with the skin can be prevented. In addition, as such an elastic sheet, in particular, a plurality of elastic members 35 are arranged in parallel with each other and have the same stretching force in the respective orientation directions, so that any one of the original sheets can be used. The elastic sheet can be cut out from the position and used for manufacturing the shorts 1. Therefore, the number of elastic sheets that can be cut out per unit area can be greatly increased, which is preferable from the viewpoints of processability, waste reduction, manufacturing cost reduction, and the like.

As the sheet base material 34, various materials generally used for clothes such as disposable diapers and shorts, such as knitted fabrics, woven fabrics, nonwoven fabrics, or combinations thereof, can be used. As the elastic member 35 fixed to the sheet substrate 34, various materials used for clothing such as disposable diapers and shorts, such as thread rubber, flat rubber, and elastic film, can be used. A method for fixing the elastic member 35 to the sheet base material 34 is not particularly limited, and examples thereof include an adhesive, heat fusion, ultrasonic fusion, and stitching. Is preferred.
As the elastic sheet comprising the sheet base material 34 and the plurality of elastic members 35 fixed to the sheet base material 34, “MEXLAR” manufactured by Toray DuPont can be preferably used.

As mentioned above, although preferable embodiment of this invention was described, this invention is not restrict | limited to embodiment mentioned above.
For example, in the above-described embodiment, the leak-proof layer 8 is formed by disposing the separate leak-proof sheet 81 on the skin facing surface side of the elastic sheet 41 forming the crotch part 4. The leak-proof layer 8 can also be formed by laminating a molten resin on the skin facing surface or the non-skin facing surface of the elastic sheet 41. Further, the elastic sheets 21, 31, 41 may be a single continuous sheet. Further, the elastic sheet 41 forming the crotch part 4 may be made to coincide with the longitudinal direction instead of making the high expansion / contraction direction coincide with the width direction of the diaper.

  The sanitary shorts of the present invention may be sanitary shorts in addition to incontinence shorts, and the sanitary shorts may be used with a known sanitary napkin or liner fixed to the inner surface. May be used alone.

It is a perspective view which shows the shorts for incontinence as one Embodiment of this invention.
