In this embodiment, as will be described later, the fabric 1 starts with gloves 10 (see FIGS. 6 and 7), raincoat 11 (see FIG. 10), socks, underwear (for example, disposable pants 12) and work clothes. Disposable clothing, sleepwear, pillowcases, bedding such as sheets, covers such as futons, furniture covers such as chairs and sofas, covers for miscellaneous goods such as cushions and cushions, box tissue and toilet seats, car seats and handles It can also be used as daily covers such as covers, towels, handkerchiefs, masks, mats, aprons and sweat pads, packaging sheets for various products, bags, bags, curtains, etc. .

FIG. 1 is a diagram showing the surface state of the fabric 1 of the present embodiment, FIG. 2 is a diagram showing the heel portion 6 of the fabric 1, FIG. 3 is an enlarged view of the fabric 1, and FIG. 3 will be used to explain the dough 1. In FIG. 1, the fabric 1 is continuous in the X direction, which is the longitudinal direction (first direction). Reference numeral 5 denotes an elastic member provided inside the fabric 1, and an aspect in which a large number of uneven surfaces are formed by the large number of elastic members 5 is shown in the figure. As shown in FIG. 2, a large number of flanges 6 are repeatedly formed along the Y direction by the large number of uneven surfaces. As is clear from FIGS. 1 and 2, the elastic member 5 is provided along the X direction, and applies elastic force in the X direction to the fabric 1. A plurality of such elastic members 5 are provided at predetermined intervals in the Y direction, which is the short direction (second direction).

A linear elastic body 5a having elasticity is used as the elastic member 5, and a synthetic material based on urethane or silicon or natural rubber can be used as the linear elastic body 5a.
In addition, when the lattice-shaped elastic member is used, it is also possible to form the above-described many flanges 6 in one lattice shape. In addition, a stretchable film may be used as the elastic member in place of the large number of elastic members 5. As the stretchable film, a stretchable elastic film such as a urethane film, a silicon film, or an elastomer film can be used.
In the present embodiment, description will be made assuming that polyurethane is used as the linear elastic body 5a.

4 is a cross-sectional view of the fabric 1 taken along line AA in FIG. 3, and FIG. 5 is a cross-sectional view of the fabric 1 taken along line BB in FIG. As shown in FIGS. 4 and 5, the fabric 1 includes a first fibrous sheet 2 that is a breathable sheet, a second fibrous sheet 3 that is also a breathable sheet, and a first fibrous sheet 3. And a fiber sheet 4 having liquid diffusibility interposed between the second

fibrous sheets

2 and 3, and the first and second

fibrous sheets

2 and 3 and the fiber sheet 4 are laminated. It is comprised by the laminated sheet 15 formed. The first and second

fibrous sheets

2 and 3 constitute a fiber layer having air permeability, and the fiber sheet 4 is a sheet constituting a fiber layer having liquid diffusibility. Thus, the lamination sheet 15 is comprised from 3 layers. The laminated sheet 15 may have a two-layer configuration by omitting the fiber sheet 4, or may have a two-layer configuration by omitting the second fibrous sheet 3. Further, various sheet members may be added to the inner side (skin surface side) of the first fibrous sheet 2, and various sheet members (for example, a moisture permeable film) may be added to the inner side or the outer side of the second fibrous sheet 3. May be added. Further, the elastic member 5 may be omitted. In this case, the heel part 6 is not formed on the fabric 1.

As will be described later, the configuration of the fabric 1 is changed to various fabrics 1a to 1d.
In this embodiment, as will be described later, when the fabric 1 is applied to the glove 10, the raincoat 11, and the disposable pants 12, the side on which the first fibrous sheet 2 is in contact with the user's skin (skin surface) Side), and the second fibrous sheet 3 becomes the outside (outside side).

In the present embodiment, the first fibrous sheet 2 is a nonwoven fabric, and a two-layer or three-layer spunpond nonwoven fabric can be used. When the first fibrous sheet 2 is used on the skin surface of the disposable pants 12, it is preferable to use a hydrophilic nonwoven fabric for the first fibrous sheet 2. When the fabric 1 is required to be hydrophilic, for example, a hydrophilic treatment such as adding a hydrophilizing agent to the fabric 1 may be performed.
Incidentally, the basis weight of the first fiber sheet 2 is preferably 10 ~ 50 g / m ² as an example, the viewpoint from 10 ~ 20 g / m ² of production costs do not preferred but is not limited thereto.

In the present embodiment, the second fibrous sheet 3 is a nonwoven fabric, and a two-layer or three-layer spunpond nonwoven fabric can be used. When the second fibrous sheet 3 is used on the outer surface of the disposable pants 12, it is desirable to use a water-repellent sheet. As the water-repellent nonwoven fabric, a three-layer spun pond nonwoven fabric can be used, and it is preferable to perform a water-repellent treatment coated with a silicon-based, paraffin metal-based, or alkylchromic croid-based water-repellent agent. basis weight of, 10 ~ 50g / m ² are preferred, from the viewpoint 10 ~ 20g / m ² of production costs do not preferred but is not limited to this as an example.

In addition, it may replace with the 2nd fibrous sheet 3, and may use the moisture-permeable film (moisture-permeable material) which lets gas (air) pass and does not let liquid (for example, rain) pass. As the moisture permeable film, a film having a polyolefin resin and an inorganic filler, a film having a polyethylene resin composition and an inorganic filler, and the like can be employed. Specifically, a polyethylene microporous film However, the present invention is not limited to this. In this case, if a paper material is used as the fiber sheet 4, the transpiration and heat diffusibility are excellent, so that heat and sweat in the body are transmitted to the outside through the fiber sheet 4 and the moisture permeable film. If applied to 10 or raincoat 11, it will not be steamed. Moreover, fashionability can also be improved by performing various printing on the fiber sheet 4 or a moisture-permeable film. In addition, it is good also as a 4 layer structure by providing a moisture-permeable film in the outer side of the 2nd fibrous sheet 3. FIG.

In this embodiment, when using a paper material, the fiber sheet 4 can use the paper material formed from the material which uses pulp paper or a pulp as a main raw material. Wood pulp, synthetic pulp, waste paper pulp, etc. can be used as raw material pulp. Moreover, it is not restricted to natural fibers such as pulp, and regenerated fibers such as rayon can also be used. The basis weight of the fiber sheet 4 is preferably 10 to 50 g / m ² as an example. Moreover, when using paper material, it is preferable to give an embossing, for example, in order to give a softness | flexibility. When the fabric 1 is used for the disposable pants 12, the paper material may be preliminarily formed with the printing layer 4a and subjected to various prints.

As shown in FIG. 5, in the present embodiment, the first fibrous sheet 2 and the fiber sheet 4 are joined by an adhesive 7 applied to the peripheral surface of the elastic member 5. For this reason, in the part where the elastic member 5 does not exist, a non-adhesive part 8 where the adhesive 7 does not exist is formed between the first fibrous sheet 2 and the fiber sheet 4, and the non-adhesive part 8 creates a space 9. It is formed. In this embodiment, since the space 9 is formed by the non-bonding portion 8, each function of moisture transpiration, heat dissipation, and moisture permeability in the fabric 1 can be improved. Note that the adhesive 7 is partially (intermittently) applied to at least one of the first fibrous sheet 2 and the fiber sheet 4 in place of the adhesion via the elastic member 5 or in addition to the adhesion via the elastic member 5. May be applied to bond the first fibrous sheet 2 and the fiber sheet 4 together. Even in this case, since the joining of the first fibrous sheet 2 and the fiber sheet 4 is partial (intermittent), a space 9 is provided between the first fibrous sheet 2 and the fiber sheet 4. Can be formed.

As shown in FIGS. 2, 3, and 4, a large number of flanges 6 are formed by continuously forming convex portions 6 a and concave portions 6 b.
As described above, the elastic member 5 is disposed inside the fabric 1 as a method for forming the collar portion 6 including the convex portion 6a and the concave portion 6b. As described above, a linear elastic body 5a having elasticity is used as the elastic member 5, and polyurethane is used as the linear elastic body 5a, for example.

As shown in FIG. 1 and FIG. 2, the linear elastic body 5a is arranged in the same direction as the longitudinal direction (x direction in FIG. 1 and FIG. 2) in the direction in which the line extends, and has a large number of intervals. Linear elastic bodies 5a are arranged in parallel. That is, a large number of linear elastic bodies 5a are arranged at intervals in the Y direction, and a large number of linear elastic body rows are formed. The intervals at which the linear elastic bodies 5a are provided in the Y direction may be substantially equal intervals or different intervals.
Instead of this, or in combination with this, the elastic force of the linear elastic body 5a may be the same or different. In any case, when the fabric 1 is used as the disposable pants 12, the linear elastic body is such that the elastic force of the body mounting portion 13 (see FIG. 12) is larger than the elastic force of other portions. What is necessary is just to arrange | position 5a.

As described above, the linear elastic body 5 a is provided between the first fibrous sheet 2 and the fiber sheet 4. The collars 6 are formed in multiple rows at predetermined intervals in the X direction in FIGS. Here, a joint portion of the heel part 6 with the linear elastic body 5a is referred to as a heel part support point. The number of the linear elastic bodies 5a per unit area can be arbitrarily set. However, if the number of the linear elastic bodies 5a is increased to reduce the interval between the linear elastic bodies 5a, the wrinkles in the row of ridges can be thereby reduced. Since the number of part support points increases, the convex parts 6a and the concave parts 6b in the row of collar parts 6 can be formed in a uniform shape and the shape can be maintained. Thereby, the shape of the heel part 6 is not lost, which is preferable from the viewpoint of increasing the flexibility, moisture transpiration, heat dissipation, and moisture permeability of the fabric 1. For this purpose, the interval between the flanges 6, that is, the pitch interval between the convex portions 6 a is preferably 2 mm to 7 mm. The pitch interval between the convex portions 6a is more preferably 3.00 mm to 6.25 mm. By narrowing the pitch interval between the convex portions 6a, fine wrinkles can be made, so that the appearance is beautiful, the contact area with one skin per wrinkle is small, the touch is improved, and the surface area is further increased. Since it becomes larger, absorbability such as sweat is improved. On the other hand, by widening the pitch interval between the convex portions 6a, the elastic force of the polyurethane can be moderately suppressed, and the manufacturing cost can be reduced.

Since the fabric 1 (also referred to as a laminated sheet 15) has a long dimension, cutting is performed to make the length dimension of the laminated sheet 15 in the longitudinal direction (the x direction in FIGS. 1 and 2) a predetermined length. . In this cutting, the first fibrous sheet 2, the fiber sheet 4, and the elastic member 5 are cut. Due to the cutting of the elastic member 5, the elastic member 5 in the tensioned state is released from the tensile force and contracted by the restoring force. The fabric 1 (laminated sheet 15) composed of the first fibrous sheet 2, the fiber sheet 4 and the like is subjected to a force in a direction in which the length becomes shorter due to the shrinkage stress at this time. A concave-convex surface is formed on the surface, thereby forming the flange 6. In this way, the dough 1 having a large number of collars 6 is manufactured.
Note that the cloth 1 may be contracted from the stretched state by slowing the conveying speed of a not-illustrated conveying device (conveying roll) that conveys the cloth 1 before cutting.

Here, the fabric 1 is contracted by the restoring force of the elastic member 5, that is, in a non-tensile state, and extends in a direction (Y direction) orthogonal to the longitudinal direction (X direction) of the elastic member 5 in the non-tensile state. A number of ridges 6 are formed, and a row of ridges is patterned on the laminated sheet 15.

The elasticity is provided to the laminated sheet 15 by the elastic member 5 disposed inside the laminated sheet 15. Accordingly, when the fabric 1 constituted by the laminated sheet 15 is pulled by hand in the X direction in FIGS. 1 and 2, the elastic member 5 extends and the fabric 1 also expands and spreads. When the hand is released from this state, the elastic member 5 contracts due to the restoring force, and the cloth 1 also returns to its original dimension. Thus, since the cloth 1 has stretchability, when the cloth 1 is used as a disposable garment, it has an excellent fit to the body. Moreover, since the dimension as a disposable garment is determined by the dimension contracted by the restoring force of the elastic member 5, the fabric 1 has a large surface area in the stretched state.

The description of the various uses and manufacturing methods of the fabric 1 (laminated sheet 15) configured as described above will be continued below.
FIG. 6 is a diagram showing an example of using the laminated fabric 1a and the laminated fabric 1b as a glove 10, and FIG. 7 is a diagram showing an example of using the fabric 1a and the fabric 1b as a universal glove 10a. It is.
As shown in FIG. 6, the glove 10 is a glove of a type separated into five fingers, and joins the fabric 1a on the front side (back side of the hand) and the fabric 1b on the back side (palm side) (for example, super Sonic bonding, heat sealing, etc.). In the present embodiment, the fabric 1a is the first fibrous sheet 2, the fiber sheet 4, the elastic member 5, and the second fibrous sheet 3 from the side in contact with the back of the hand. May be omitted, and a film (for example, a moisture permeable film) may be used instead of the second fibrous sheet 3. By providing the elastic member 5 on the back side of the hand, the glove 10 expands and contracts according to the wearer's hand, so that it can be fitted to the wearer's hand. For this reason, if the insertion part of the hand of the glove 10 is made larger, it is easy to put in and out of the hand, and the glove 10 fitted to the hand can be realized.

The fabric 1b is composed of a first fibrous sheet 2, a fiber sheet 4, and a second fibrous sheet 3 from the side in contact with the palm, but instead of the second fibrous sheet 3, a film (for example, a moisture permeable film) The elastic member 5 may be provided between the first fibrous sheet 2 and the fiber sheet 4 or between the fiber sheet 4 and the second fibrous sheet 3. One of the fiber sheet 4 and the second fibrous sheet 3 may be omitted. The fabric 1a and the fabric 1b may have the same configuration.

Since the first fibrous sheet 2 touches the back and palm of the hand, the glove 10 of the present embodiment has a soft feel and excellent breathability when the glove is worn. In addition, since the fiber sheet 4 is bonded to the first fibrous sheet 2, the sweat is easily transmitted to the fiber sheet 4 even when sweat comes from the back and palm of the hand, and the fiber sheet can absorb the sweat. As a result, the wearer is comfortable with no discomfort when using conventional gloves (eg, vinyl gloves).

FIG. 7 shows a universal glove 10 a that can be used with either the left or right hand. Like the glove 10, the universal glove 10 a is formed by joining a front side fabric 1 a and a back side fabric 1 b. In the present embodiment, as shown in FIG. 7, the part where the finger enters is a three-divided type, but it may be a two-divided type.
The universal glove 10a of the present embodiment has front and back (back of hand, palm side) compatibility in addition to left and right compatibility. If the fabric 1a side is used as the back side of the hand, the elastic member 5 fits and fits the user's hand, and there is no elastic member 5 on the palm side. Yes. On the other hand, when touching a hot thing (for example, a handle of a kettle), since it touches via the elastic member 5, the contact area which a handle touches a hand can be reduced, or the way of heat transmission becomes slow. It becomes difficult to feel.

The

gloves

10, 10a of the present embodiment can be used for various purposes such as cold protection, medical use, work use (assembly, adjustment, cleaning, cleaning), and sports. When used for medical purposes, it is preferable to use a melt blown nonwoven fabric composed of ultrafine fibers having a fine diameter in the range of 2 to 20 microns and having excellent filter performance. In this case, a melt-blown nonwoven fabric layer may be added to the laminated sheet 15, and a melt-blown nonwoven fabric may be used instead of at least one of the first and second

fibrous sheets

2 and 3.
In addition, you may employ | adopt a mittens shape as a shape of the

gloves

10 and 10a.

FIG. 8 is a schematic diagram showing a production line 100 for the glove 10 (10a), and FIG. 9 is a flowchart showing a method for producing the glove 10 (10a). In addition, manufacture of this cloth | dough 1 is performed by control of the control apparatus not shown provided with CPU of FA factory. Hereinafter, the description will be continued with reference to FIGS. 8 and 9, but the layout of the production line 100 in FIG. 8 is merely an example, and the arrangement of various devices can be changed as appropriate depending on the space of the factory.

(Step S1: Production of dough 1a)
The fiber sheet 4 wound around the sheet roll 104a is conveyed in the X direction, embossed by a pair of embossing rolls 110a, and subjected to a mechanical softening process. Since a plurality of embossing rolls 110 are used in the production line 100, an explanation will be given by adding alphabets. However, the same embossing roll 110 may be used, and embossing patterns 110 having different embossing patterns, sizes, and materials are used. May be. Further, since a plurality of sheet rolls 104 for holding the fiber sheet 4 are used, an explanation will be given by adding alphabets.
In addition, the pattern of the glove 10 is printed in advance on the back surface (opposite surface to the second fibrous sheet 3) of the fiber sheet 4 wound around the sheet roll 104a, and the fiber sheet 4 on which the pattern is printed is printed. On the other hand, the above-mentioned embossing is given.

The fiber sheet 4 that has passed through the embossing roll 110 is coated with the adhesive 7 by the adhesive coating device 111 for bonding with the first fibrous sheet 2. In the present embodiment, hot melt is used as the adhesive 7, but is not limited to this. The adhesive application device 111 has a plurality of nozzles and sprays hot melt in a mist form. Note that the adhesive 7 is heated to a predetermined temperature (for example, 60 ° C. to 150 ° C.) by the adhesive application device 111, and a hot melt of 0.8 g / m ² to 2.0 g / m ² is applied.

The first fibrous sheet 2 wound around the sheet roll 102a is conveyed in the −Z direction by the conveying roll 112a, and is joined to the fiber sheet 4 to which the adhesive 7 is applied by the pressing roll 113a. In addition, since a plurality of transport rolls 112 are used in the production line 100, an explanation is given by adding alphabets, but the same transport roll may be used, or transport rolls having different sizes and rotation speeds may be used. Further, since a plurality of pressing rolls 113 are used, an explanation will be given by adding alphabets, but the same pressing roll 113 or different pressing rolls may be used, and the number, size, and pressing force can be set as appropriate. it can.

The adhesive 7 is applied to the elastic member 5 wound around the elastic roll 105 by the adhesive application device 111. In this embodiment, hot melt is used as the adhesive 7 applied to the peripheral surface of the elastic member 5, but is not limited to this. Further, the hot melt used in the present embodiment may be the same in each step, or may be different (for example, different in viscosity). The adhesive 7 is heated to a predetermined temperature (for example, 60 ° C. to 150 ° C.) by the adhesive application device 111. In order to simplify the drawing, only one elastic roll 105 is shown, but a plurality of elastic rolls 105 are arranged according to the number of elastic members 5 to be used.

The second fibrous sheet 3 wound around the sheet roll 103a is conveyed in the + Z direction by the conveyance roll 112b. On the other hand, the first fibrous sheet 2 and the fiber sheet 4 joined as described above are conveyed in the −Z direction by the conveying roll 112b. The pair of pressing rolls 113b press and bond the second fibrous sheet 3, the bonded first fibrous sheet 2 and the fibrous sheet 4 through the elastic member 5 to which the adhesive 7 is applied. To do. Thereby, the dough 1a (laminated sheet 15) is manufactured. The fabric 1a is laminated in the order of the first fibrous sheet 2, the fiber sheet 4, the elastic member 5, and the second fibrous sheet 3 from the top.

(Step S2: Heat treatment of the dough 1a)
As described above, elasticity is imparted to the fabric 1a by the elastic member 5 disposed inside the fabric 1a. By selecting the elastic force of the elastic member 5, the surface area can be increased from about 1.5 times to about 5 times. For example, if the dimension required in the X direction is 100 mm, the fabric 1a (extended state) of 150 mm to 500 mm is used.
When the shrinkage rate (catalog value or theoretical value) due to the restoring force of the elastic member 5 is 1/3, the dimension in the X direction of the fabric 1a needs to be 300 mm multiplied by the reciprocal of the shrinkage rate of the elastic member 5. However, the first fibrous sheet 2, the second fibrous sheet 3, and the fiber sheet 4 are actually joined through the elastic member 5 and then cut, or the stretched state is released by reducing the transport speed of the transport roll. Even in this case, the shrinkage rate may be ½. This is, for example, a problem of temperature and humidity in a manufacturing factory, particularly when temperature control is not performed and the temperature is low, a problem of the elastic member 5 alone (for example, residual strain of the elastic member 5), and application to the elastic member 5. This is caused by a decrease in shrinkage of the elastic member 5 due to the curing of the adhesive 7 and the rigidity of the fiber sheet 4. Furthermore, the application conditions (application temperature, application amount, viscosity, etc.) of the adhesive 7 may also be affected. Similarly, the application conditions (application temperature, application amount, viscosity, etc.) of the adhesive 7 may also be affected.

Therefore, by heating the fabric 1a with the heating device 114, the residual strain of the elastic member 5 is removed by annealing, so that the contraction rate of the elastic member 5 is increased. The heating device 114 is a non-contact heating device that supplies hot air of 30 ° C. to 80 ° C., for example. In the heat treatment, the fabric 1a is conveyed in an extended state. In this embodiment, non-contact heating by the heating device 114 is performed as the heat treatment. However, contact-type heating may be performed by bringing a heating roll (not shown) into contact with the fabric 1a.

In addition, even when the elastic member 5 is omitted from the fabric 1a, the above-described heat treatment may be performed. By the heat treatment, the first fibrous sheet 2, the second fibrous sheet 3, and the fiber sheet 4 can be joined better, and generation of wrinkles and joining peeling can be prevented. This can also be applied to the production of the fabric 1b described later.

(Step S3: Fabrication of dough 1b)
The fiber sheet 4 wound around the sheet roll 104b is conveyed in the + X direction, embossed by a pair of embossing rolls 110b, and subjected to a mechanical softening process. The fiber sheet 4 wound around the sheet roll 104b may be printed in advance. The fiber sheet 4 that has passed through the embossing roll 110 is coated with the adhesive 7 by the adhesive coating device 111 for bonding with the second fibrous sheet 3.

The second fibrous sheet 3 wound around the sheet roll 103b is conveyed in the −Z direction by the conveying roll 112c, and is joined to the fiber sheet 4 to which hot melt is applied by the pair of pressing rolls 113c. Thereafter, the adhesive 7 is applied to the fiber sheet 4 by the adhesive application device 111 for bonding to the first fibrous sheet 2.

The first fibrous sheet 2 wound around the sheet roll 102b is joined to the joined second fibrous sheet 3 and fiber sheet 4 by a pair of pressing rolls 113d. Thereby, the dough 1b is manufactured. When the fabric 1 and the fabric 1b have the same configuration, the production line 100 may be simplified by omitting the production portion of the fabric 1b, or the productivity may be improved by leaving the production portion of the fabric 1b. Good.

(Step S4: Joining of the cloth 1a and the cloth 1b)
The cloth 1a and the cloth 1b are pressed by the pressing roll 113e, and the cloth 1b is placed on the cloth 1. In this embodiment, it is assumed that the fabric 1 and the fabric 1b are not joined in this state. The joining device 115 joins the cloth 1 and the cloth 1b by heat sealing or ultrasonic bonding. In this embodiment, joining according to the external shape of the glove 10 (10a) is performed. The joining by the joining device 115 is a joining including a margin in consideration of a cutting error in a cutting process described later. Note that as the joining device 115, joining using an adhesive may be performed, or joining by sewing may be performed.

(Step S5: Cutting)
The fabric 1a and the fabric 1b joined to match the outer shape of the glove 10 (10a) are cut by a cutting device 116 having a cutter, whereby the glove 10 (10a) is manufactured. In the present embodiment, the cutting is performed after joining the fabric 1a and the fabric 1b, but this order may be changed. Instead of this, the heat sealing heat may be used for cutting when the fabric 1a and the fabric 1b are joined by heat sealing. Alternatively, the fabric 1a and the fabric 1b may be joined and cut using a seal cutter that combines ultrasonic joining and a cutter. According to this, since the cloth 1a and the cloth 1b can be joined and cut at the same time, the manufacturing efficiency of the glove 10 (10a) can be increased. In addition, in this embodiment, since the glove 10 (10a) is cut | judged in the state turned over, the glove 10 (10a) should just be turned over by the turn-over apparatus not shown after cutting.

Next, the description of the second embodiment will be continued. In the second embodiment, the same constituent elements as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
FIG. 10 is a diagram illustrating an example in which the laminated fabric 1 c and the laminated fabric 1 d are joined and used as the raincoat 11.
The raincoat 11 is the first fibrous sheet 2, the elastic member 5, the fiber sheet 4, and the moisture permeable film 20 which is a moisture permeable member from the skin surface of the wearer. Various modifications such as inserting a second fibrous sheet between 4 and the moisture permeable film 20 can be performed.

In FIG. 10, arrows in the X and Y directions are attached as in FIG. 1. In the second embodiment, although not shown, the elastic member 5 is disposed so as to expand and contract in the X direction. For this reason, the raincoat 11 fits a wearer's body. The elastic member 5 may be disposed along the Y direction in a part of the raincoat 11 so that a part of the raincoat 11 expands and contracts in the Y direction.
As described above, the raincoat 11 is the first fibrous sheet 2 having a breathable skin surface, and even when the wearer sweats, the sweat is quickly transmitted to the fiber sheet 4, and the sweat is absorbed. It can be sucked by the fiber sheet 4. For this reason, the raincoat 11 of this 2nd Embodiment does not have the feeling of stuffiness which a wearer feels when wearing a conventional raincoat, and becomes comfortable. Furthermore, since the moisture-permeable film 20 releases moisture to the outside and prevents the rain from entering from the outside, the wearer can wear the raincoat 11 comfortably.

FIG. 11 is a schematic diagram showing a production line 200 for the raincoat 11. The description overlapping with the production line 100 will be omitted, and the description will be continued with a focus on differences from the production line 100.
The difference between the cloth 1a and the cloth 1c is that a moisture permeable film 20 wound around a film roll 120a is used instead of the second fibrous sheet 3. Moreover, the point from which the sheet roll 102a holding the 1st fibrous sheet 2 is arrange | positioned below and the film roll 120a holding the moisture-permeable film 20 is arrange | positioned upwards differs from the above-mentioned embodiment.
Similarly, the difference between the fabric 1b and the fabric 1d is that a moisture permeable film 20 wound around a film roll 120b is used instead of the second fibrous sheet 3. Moreover, the point from which the sheet roll 102b holding the 1st fibrous sheet 2 is arrange | positioned upwards, and the film roll 120a holding the moisture-permeable film 20 is arrange | positioned below differs from the above-mentioned embodiment.

By adopting such a layout, in the second embodiment, the moisture permeable film 20 of the fabric 1c and the moisture permeable film 20 of the fabric 1d become the bonding surface. In the above-described embodiment, the first fibrous sheet 2 of the fabric 1a and the first fibrous sheet 2 of the fabric 1b are joined surfaces. However, it is better to use the moisture permeable films 20 as joined surfaces. Strength increases. For this reason, the raincoat 11 with improved durability against wind and rain can be realized. Note that the bonding strength between the moisture-permeable films 20 is stronger than the bonding between the fiber sheets 4.

The moisture permeable film 20 joined on the inside becomes the outside in the raincoat 11. For this reason, in the second embodiment, a step of turning over the raincoat that has been joined and cut by a turning device (not shown) is added. In addition, as a reversing device, a method of blowing a compressed gas (for example, air) onto the bonded

fabrics

1c and 1d and turning them over, a method of turning the bonded

fabrics

1c and 1d by vacuum suction, or a fabric 1c using a mechanical arm. Various methods such as a method of turning 1d upside down can be adopted.

In this way, if the moisture permeable film 20 is joined inside and turned upside down, when the raincoat 11 is worn, the moisture permeable film is on the outside and the joining surface is on the inside, thus increasing the joining strength of the

fabrics

1c and 1d, A good-looking raincoat 11 can be realized. In addition, in the manufacture of the above-described glove 10 (10a), the moisture permeable film 20 is used instead of the second fibrous sheet 3, and the outer side is a moisture permeable film if a reversing step is added by a turning device. It is possible to realize the glove 10 (10a) whose surface is the inside.

Next, the description of the third embodiment will be continued. In the third embodiment, the same constituent elements as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
FIG. 12 is a diagram illustrating an example in which the laminated fabric 1 a and the laminated fabric 1 b are used as the disposable pants 12 in the same manner as the glove 10. The disposable pants 12 are a hybrid type in which a front side and a rear side are constituted by a fabric 1b, and a front fabric 1b and a rear fabric 1b are joined by a fabric 1a. Moreover, as for the trunk | drum mounting | wearing part 13, the surface 1 (outer side) becomes the fabric 1b, and the fabric 1a is joined to this front side fabric 1b from the back side (inside).

The fabric 1a has a three-layer structure of the first fibrous sheet 2, the elastic member 5, the fiber sheet 4, and the second fibrous sheet 3 from the inner side (skin surface side). One of the fibrous sheets 3 may be omitted to form a two-layer structure, and the moisture permeable film 20 may be used instead of one of the fiber sheet 4 and the second fibrous sheet 3. May be added to form a four-layer structure.

The fabric 1b has a three-layer structure of the first fibrous sheet 2, the fiber sheet 4, and the second fibrous sheet 3 from the inner side (skin side), but the fibrous sheet 4 and the second fibrous sheet. 3 may be omitted to form a two-layer structure, or a moisture permeable film 20 may be used instead of one of the fiber sheet 4 and the second fibrous sheet 3, and the moisture permeable film 20 may be added. A four-layer structure may be used. In the third embodiment, the elastic member 5 is not disposed on the fabric 1b, and thus the manufacturing cost of the disposable pants 12 can be reduced. The elastic member 5 may be disposed on the fabric 1b. Although not shown, the fiber sheet 4 is printed, and the fashionability of the disposable pants 12 is improved.

FIG. 13 is a schematic diagram showing a production line 300 for the disposable pants 12. The description overlapping with the production line 100 will be omitted, and the description will be continued with a focus on differences from the production line 100.
The difference from the production line 100 is that the arrangement of the first fibrous sheet 2 and the second fibrous sheet 3 is different in the production of the fabric 1a and the fabric 1b. By doing in this way, the joint surface of the cloth 1a and the cloth 1b becomes the inside (skin surface) of the disposable pants 12, and the joint surface does not face outward, improving the fashionability of the disposable pants 12. be able to.

Since the glove 10, the raincoat 11, and the disposable pants 12 of this embodiment can endure several times of washing, they are economical and environmentally friendly.
Moreover, the glove 10, the raincoat 11, and the disposable pants 12 of this embodiment can be used regardless of age, sex, and body shape (for children, for men, for women, etc.), and for animals such as pets. Can be applied.

Hereinafter, the present invention will be described in more detail with reference to specific examples of the stretchable composite sheet used in the present invention. In addition, the lamination sheet 15 is comprised in the order of the following description.
Example 1
As the first fibrous sheet 2, a hydrophilic spunbond nonwoven fabric (weight per unit area 15 g / m ² ) is used, and as the

fiber sheet

4, 100% pulp paper (paper sheet for tissue paper: basis weight 13 g / m ² ). Was used without printing. Milky film (basis weight 18 g / m ²⁾ used as the moisture-permeable film 20, as a second fibrous sheet 3, using a water-repellent spunbonded nonwoven fabric (basis weight 15 g / m ^2), a hot-melt adhesive (hot the sheet material obtained by bonding a total basis weight 62.2 g / m ² was as in example 1 by the total basis weight of 1.2 g / m ²⁾ of the melt adhesive.

Example 2
The fiber sheet 4 was printed with the same configuration as in Example 1.

Example 3
As the first fibrous sheet 2, a water-repellent spunbond nonwoven fabric (weight per unit area 15 g / m ² ) is used, and as the

fiber sheet

4, 100% pulp paper (paper sheet for tissue paper: basis weight 13 g / m ² ) Was used without printing. Milky film (basis weight 18 g / m ²⁾ used as the moisture-permeable film 20, as a second fibrous sheet 3, using a water-repellent spunbonded nonwoven fabric (basis weight 40 g / m ^2), a hot-melt adhesive (hot the sheet material obtained by bonding a total basis weight 87.2 g / m ² was as in example 3 by the total basis weight of 1.2 g / m ²⁾ of the melt adhesive.

Comparative Example 1
As the first fibrous sheet 2, a water-repellent spunbonded nonwoven fabric (weight per unit area: 15 g / m ² ) is used. As the moisture permeable film 20, a milky white film (weight per unit area: 18 g / m ² ) is used. % Paper (paper sheet for tissue paper: basis weight 13 g / m ² ) was used without printing. As the second fibrous sheet 3, a hydrophilic spunbond nonwoven fabric (weight per unit area: 15 g / m ² ) was used and adhered by a hot melt adhesive (total weight per unit area of hot melt adhesive: 1.2 g / m ² ). The obtained sheet material having a total basis weight of 62.2 g / m ² was determined as Example 3.

First, the water absorption quick-drying (transpiration rate) of the sheet materials of Examples 1 to 3 and Comparative Example 1 was evaluated.
First, the water-absorbing quick-drying property (transpiration property) was subjected to a transpiration property (II) test (Boken standard BQEA028), and both water absorption property and quick-drying property were comprehensively evaluated.
Test pieces each having a diameter of about 9 cm were prepared on the laminated sheets of Examples 1 to 3 and Comparative Example 1, and the mass (W) of each test piece and the petri dish was measured. Next, 0.1 mL of water was dropped onto the petri dish, a test piece was placed thereon, and the mass (W0) was measured. This was allowed to stand under standard conditions (20 ° C., humidity 65% RH), and the mass (Wt) for each predetermined time (5 minutes, 10 minutes, and thereafter every 10 minutes until 60 minutes) was measured. From the measured masses W, W0 and Wt, the transpiration rate (%) for each predetermined time was calculated using the following formula (1).
Transpiration rate (%) = {(W0−Wt) / (W0−W)} × 100 (1)
The results are shown in Table 1.

As is apparent from the transpiration rate results shown in Table 1, in Comparative Example 1, the transpiration rate is 15% or less after 60 minutes, whereas in Examples 1 to 3, the transpiration rate is 10 minutes after the lapse. More than 20%, transpiration rate exceeds 40% after 20 minutes, transpiration rate exceeds 70% after 30 minutes, transpiration rate exceeds 85% after 40 minutes, and transpiration rate after 50 minutes It is understood that the transpiration rate exceeded 98% after 60 minutes.

In the Boken standard BQEA028, as a guideline for evaluation, the transpiration rate for 20 minutes after the start of the test is preferably 50% or more for woven fabrics and 40% or more for knits for sports applications, It is said that 40% or more of the woven fabric and 30% or more of the knitted fabric are preferable.
Therefore, since the sheet material of Example 1 can obtain a transpiration rate of 40% or more, it can be said that it can be comfortably worn for both sports use and general use.
From the above, it can be seen that the fabric of this example using the laminated sheets of Examples 1 to 3 has extremely high water absorption and quick drying (transpiration rate).

The total basis weight of the laminated sheet 15 is, for example, as described above if the basis weights of the first fibrous sheet 2 and the second fibrous sheet 3 are adjusted to 50 g / m ² to 100 g / m ^2. High water absorption quick-drying (transpiration rate) can be obtained.

Also, a transpiration (II) test (Boken method) for evaluating the sweat-absorbing and quick-drying properties of the fabric was adopted in ISO17617. When the data in Table 1 is applied to this test method, the following results are obtained.

The unit of drying time (increase in transpiration rate per unit time, Drying rate) is% / min, and the unit of drying rate (time for transpiration rate to reach 100%, Drying time) is in minutes. From Table 2, it can be said that the laminated sheets 15 of Examples 1 to 3 have a drying rate of 2.0 or more and a drying rate of 50 minutes or less.

Although the present embodiment has been described above, the present invention is not limited to this, and it goes without saying that various modifications and appropriate combinations are possible. The technical scope of the present invention is not limited to the scope described in the above embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
