Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the surface state of the fabric 1 of the present embodiment. In the present embodiment, as will be described later, the fabric 1 is used as an exterior sheet 11 (see FIG. 9) of the disposable pants 10 which is a disposable fiber product, or, for example, a surface material 15 (see FIG. 10). 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, 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). 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.

As shown in FIG. 4 and FIG. 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, 2 A laminated sheet 30 having a fiber material 4 having liquid diffusibility interposed between the

fibrous sheets

2 and 3 and laminating the first and second

fibrous sheets

2 and 3 and the fiber material 4. Consists of. The first and second

fibrous sheets

2 and 3 constitute a fiber layer having air permeability, and the fiber material 4 is a sheet constituting a fiber layer having liquid diffusibility. Thus, the lamination sheet 30 is comprised from 3 layers. In the present embodiment, as will be described later, when the fabric 1 is applied to the surface material 15, the first fibrous sheet 2 is in contact with the user's skin, and the second fibrous sheet 3 is the absorbent body. 14 is the side in contact with 14. For this reason, it may replace with the 2nd fibrous sheet 3, and it may be set as a 3 layer structure using the fiber material 4, and it is good also as a 2 layer structure which abbreviate | omitted the 2nd fibrous sheet 3. FIG. Furthermore, the fiber material 4 may be omitted, and a two-layer configuration including the first fibrous sheet 2 and the second fibrous sheet 3 may be employed. In the present embodiment, in order to simplify the description, even when the fabric 1 is applied as the exterior sheet 11 and the surface material 15, the three layers composed of the surface material first, second

fibrous sheets

2, 3 and the fiber material 4 are used. The description will be continued as the configuration, but is not limited to this.

The first fibrous sheet 2 and the fiber material 4 are joined intermittently via an elastic member 5. It is preferable that the joining of the second fibrous sheet 3 and the fiber material 4 is also intermittent joining. In the present embodiment, the second fibrous sheet 3 and the fiber material 4 are joined and intermittently joined and integrated so that a joined part and a joined part are formed, and then the integrated second fibrous sheet. 3. The description will be continued assuming that the elastic member 5 and the first fibrous sheet 2 are bonded to the fiber material 4.

The bonding method may be bonding, heat fusion, ultrasonic bonding, or the like, but bonding is preferable from the viewpoint of ease of work. Hereinafter, an embodiment in which adhesion is adopted as a joining method will be described.

In the bonding as a bonding method, it is preferable to use a hot melt adhesive as an adhesive. Hereinafter, an embodiment in the case of using a hot melt adhesive as the adhesive will be described. To intermittently join the second fibrous sheet 3 and the fiber material 4 using a hot melt adhesive, as shown in FIGS. 5 and 6, the hot melt adhesive is intermittently applied to the fiber material 4. It is applied (or a hot melt adhesive may be intermittently applied to the second fibrous sheet 3), and both are laminated and joined together. At this time, a non-adhesive portion 8 where the adhesive layer 7 does not exist is formed between the second fibrous sheet 3 and the fiber material 4, and a space 9 is formed by the non-adhesive portion 8. Further, since the elastic member 5 is interposed between the first fibrous sheet 2 and the fiber material 4, the first fibrous sheet 2 and the fiber material 4 are joined at the location of the elastic member 5, so that the first Intermittent coupling between the fibrous sheet 2 and the fiber material 4 is performed. That is, as shown in FIG. 5, a hot melt adhesive is sprayed and applied to the circumferential surface of a large number of elastic members 5 arranged in parallel at predetermined intervals, and the elastic member 5 coated with the hot melt adhesive is applied. Is positioned between the surface of the fiber material 4 in the laminate sheet of the second fibrous sheet 3 and the fiber material 4 and the first fiber sheet 2, and the surface of the fiber material 4 in the laminate sheet The elastic member 5 is sandwiched and laminated between the fibrous sheet 2 and joined and integrated. Although not particularly shown in FIG. 6, the opposing surface of the first fibrous sheet 2 and the fiber material 4 where the elastic member 5 does not exist is a non-adhesive portion 8, and a space 9 is formed by the non-adhesive portion 8. Yes. As described above, the structure in which the space 9 is formed by the non-bonding portion 8 improves the functions of moisture transpiration, heat dissipation, and moisture permeability in the fabric 1.

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. A linear elastic body 5a having elasticity is used as the elastic member 5, and a thread rubber is suitably used as the linear elastic body 5a. Hereinafter, an embodiment in which a linear elastic body 5a is used as the elastic member 5 will be described.

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. For example, the linear elastic bodies 5a may be densely arranged by shortening the intervals in the peripheral portion. Furthermore, the interval may be shortened from the central part of the dough 1 to the peripheral part. Since the linear elastic bodies 5a are densely arranged in the peripheral portion, when the fabric 1 is used as the surface material 15 of the absorbent body 14, the side of the surface material 15 has a function as a gather. Instead of this, or in combination with this, the elastic force of the linear elastic body 5a in the peripheral portion and the elastic force of the linear elastic body 5a in the central portion are made different, and the linear elastic body 5a in the peripheral portion is made different. The elastic force may be increased. In the present embodiment, the peripheral portion of the surface material 15 is an upper end portion of about 5 to 30% and a lower end portion of about 5 to 30% in the Y direction in FIG. It is a part excluding the part.

The linear elastic body 5a is provided between the first fibrous sheet 2 and the fiber material 4 as shown in FIG. In the present embodiment, one flange portion 6 extending from one end to the other end along the y direction (second direction different from the first direction) in FIGS. 1 and 2 is referred to as “a row of flange portions”. And The collars 6 are formed in a large number of rows at predetermined intervals in the x direction in FIGS. 1 and 2. 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 thread rubber can be moderately suppressed, and the manufacturing cost can be reduced. In FIGS. 1 and 2, the flange portion 6 is illustrated as being continuously formed. However, depending on the number of the linear elastic bodies 5 a and the arrangement method, the discontinuity may occur or the displacement may occur in the y direction. Or However, when the collar portion 6 is formed to be shifted in the y direction, for example, when the fabric 1 is used as the surface material 15, urine or the like hardly travels in the Y direction, which can contribute to prevention of side leakage. .

Here, an example of a production method for producing the fabric 1 of the present invention using a thread rubber as the linear elastic body 5a and using a hot melt adhesive as an adhesive will be described. As will be described later, a paper material is preferably used as the fiber material 4, and a hydrophilic nonwoven fabric is preferably used as each of the first fibrous sheet 2 and the second fibrous sheet 3. The method for producing the fabric 1 of the present invention will be described by taking as an example the case of using non-woven fabrics (for example, thermal bonds) as the first fibrous sheet 2 and the second fibrous sheet 3, respectively.

First, a paper material as the fiber material 4 is fed out from a roll wound body. When the fabric 1 is used for the exterior of the disposable pants, a printing layer 4a (see FIG. 4) may be formed in advance on the paper material and various prints may be applied. The fed paper material is passed through an embossing roll and pressed between the rolls to perform a mechanical softening process. This mechanical softening process may be an embossing process using a flat roll or an embossing process using a meshing roll having a large number of protrusions on the roll surface. In the latter embossing process, many fine holes are opened in the paper material. When hot-melt adhesive is intermittently sprayed on the paper material after the embossing treatment, the hot-melt adhesive penetrates into fine holes and improves the ease of adhesion to the second fibrous sheet 3. Can do. In addition, machining other than embossing may be employed, and a plurality of embossing apparatuses may be provided to perform embossing a plurality of times. In this case, the embossing apparatus may be the same, and embossing apparatuses having different embossing directions, embossing shapes and sizes may be provided. By performing the embossing, the flexibility of the fiber material 4 is improved, and the touch can be improved.

On the other hand, the second fibrous sheet 3 as the second fibrous sheet 3 is unwound from a roll wound body, and the second fibrous sheet 3 and the paper material coated with the hot melt adhesive are passed through a flat roll. The bonded sheet is manufactured by pressure bonding and laminating them. In this joined body sheet, the second fibrous sheet 3 and the paper material are joined intermittently.
A large number of thread-like rubbers are fed out from a roll wound body obtained by winding a large number of thread-like rubbers in parallel. The thread-like rubber is fed out while being pulled with a predetermined pulling force. A hot melt adhesive is sprayed on the fed rubber thread. In this case, the adhesive is sprayed continuously over the entire length of the thread rubber in the length direction. The adhesive is applied to the entire peripheral surface of the thread rubber. On the other hand, the first fibrous sheet 2 is fed out from the roll wound body, and the first fibrous sheet 2 is sent out so as to face the joined sheet, and between the joined sheet and the first fibrous sheet 2. In addition, the thread rubber is supplied so that the thread rubber coated with the adhesive as described above is sandwiched. In this case, the thread rubber is supplied between the surface of the paper material of the joined body sheet and the first fibrous sheet 2.

Threaded rubber is passed through a flat roll in a state of being sandwiched between the paper material surface of the joined sheet and the first fibrous sheet 2. The joined body sheet, the thread-like rubber, and the first fibrous sheet 2 are pressure-bonded by a flat roll and laminated and integrated. Since the first fibrous sheet 2 and the paper material are joined through thread rubber, they are joined intermittently. In this way, the laminated sheet 30 is manufactured in which the second fibrous sheet 3 and the paper material are intermittently joined and the first fibrous sheet 2 and the paper material are intermittently joined. If necessary, the laminated sheet 30 is passed through an embossing roll to perform a mechanical softening process. By performing this treatment, the flexibility of the fabric 1 can be further improved. As described above, in the present embodiment, since the fabric 1 is used as the surface material 15 of the absorbent body 14, the second fibrous sheet 3 is composed of a fiber assembly made of pulp fibers, a water-absorbing polymer, or the like. It contacts the absorber 14. For this reason, instead of the 2nd fibrous sheet 3, the paper material which was excellent in liquid permeability rather than the nonwoven fabric may be used, and the 2nd fibrous sheet 3 is abbreviate | omitted and it is good also as a 2 layer structure. In this case, the elastic member 5 may be disposed between the second fibrous sheet 3 and the fiber material 4. If the hot melt adhesive is intermittently applied to the elastic member 5 and the second fibrous sheet 3 and the fiber material 4 are bonded, the bonding (bonding) step can be reduced. Even when the elastic member 5 is disposed between the second fibrous sheet 3 and the fiber material 4, it is desirable to perform a mechanical softening treatment on the fiber material 4, and the second fibrous sheet and the fiber material 4. A hot melt adhesive may be applied to at least one of the above. Examples of the intermittent application method of the adhesive include a method of applying in a linear shape, a dot shape, a stripe shape, a spiral shape, a block shape, a pattern shape, etc. A plurality of methods may be used in combination.

Since the manufactured laminated sheet 30 has a long dimension, cutting is performed to make the length dimension of the laminated sheet 30 in the longitudinal direction (the x direction in FIGS. 1 and 2) a predetermined length. In this cutting, the first fibrous sheet 2, the second fibrous sheet 3, the paper material, and the thread rubber are cut. By cutting the thread rubber, the thread rubber that has been pulled is released from the pulling force and contracted by the restoring force. Due to the shrinkage stress at this time, the laminated sheet 30 composed of the first fibrous sheet 2, the second fibrous sheet 3, and the paper material receives a force in a direction in which the length becomes shorter. Is formed, thereby forming the flange 6. In this way, the dough 1 having a large number of collars 6 is manufactured.

Here, the fabric 1 is in a state in which the linear elastic body 5a is shrunk by a restoring force, that is, in a non-tensioned state, and the longitudinal direction of the linear elastic body 5a in the non-tensioned state (the laminated sheet 30 in FIGS. 1 and 2). A number of flanges 6 extending in a direction orthogonal to the longitudinal direction of the laminated sheet, that is, the same direction as the x direction (the width direction of the laminated sheet 30 in FIGS. 1 and 2, that is, the same direction as the y direction) are formed. The buttock row is patterned.

Elasticity is imparted to the laminated sheet 30 by the linear elastic body 5 a disposed inside the laminated sheet 30. Therefore, when the fabric 1 constituted by the laminated sheet 30 is pulled by hand in the x direction in FIGS. 1 and 2, the linear elastic body 5a extends and the fabric 1 also expands and spreads, and when the hand is released from this state, The linear elastic body 5a contracts due to its restoring force, so that the fabric 1 also returns to its original dimensional state. Thus, since the cloth 1 has stretchability, when the cloth 1 is used as the surface material 15 of the absorbent body 14, the fit to the body is excellent. Similarly, when the fabric 1 is used as the exterior sheet 11 of the disposable pants 10, the fit to the body is excellent.

In the case where a hydrophilic nonwoven fabric is used as the first fibrous sheet 2 and the second fibrous sheet 3, as hydrophilic fibers, for example, vinyl alcohol fibers and hydrophilic fibers from the viewpoint of adhesion to the hydraulic composition. Polypropylene fibers can be used. The basis weight of each of the first fibrous sheet 2 and the second fibrous sheet 3 is preferably 10 to 50 g / m ² as an example.
When a paper material is used as the fiber material 4, a paper material formed from pulp paper or a material mainly composed of pulp can be used. 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 material 4 is preferably 10 to 50 g / m ² as an example. The fabric 1 manufactured as described above is applied to the outer sheet 11 of the surface material 15 and the disposable pants 10 as the first sheet portion of the present embodiment.

FIG. 7 is a view showing the disposable pants 10 of this embodiment, and FIG. 8 is a partially enlarged view of the disposable pants 10 of this embodiment.
The disposable pants 10 include an exterior sheet 11 obtained by cutting the fabric 1 for the disposable pants 10, a body mounting portion 12 that is formed by bending both ends of the exterior sheet 11 in the X direction, and is mounted around the waist of the user. A hook-and-loop fastener 13 provided at one end in the X direction of the exterior sheet 11 and engaged with the other end in the X direction of the exterior sheet 11 and an adjusting portion 16 (see FIGS. 9 to 12) for adjusting the dimensions are provided. ing. When the user wears the disposable pants 10, the end portion where the hook-and-loop fastener 13 is provided is the rear side (the buttock side).
As is clear from FIG. 7, the disposable pants 10 of this embodiment are an open type provided with a hook-and-loop fastener 13. Moreover, since it does not have a gather function for preventing side leakage of urine and the like and has no three-dimensional structure, it has a planar shape. For this reason, as will be described later, the elastic member 5 can be easily fitted to the shape of the user's body (for example, the buttocks) by expansion and contraction in the Y direction. In addition, you may make it add a gather function to the disposable pants 10 of this embodiment.

FIG. 9 is a schematic diagram of the disposable pants 10 of the present embodiment, and corresponds to FIGS. 7 and 8. In addition, the elastic member 5 (linear elastic body 5a) which does not appear in FIG. 7, FIG. 8 is shown by the dotted line. FIG. 10 is a view in which the absorbent body 14 provided with the surface material 15 is attached to the disposable pants 10 of the present embodiment, and the elastic member 5 (linear elastic body 5a) is omitted to simplify the drawing. ing. As indicated by arrows in the figure, the expansion / contraction direction of the surface material 15 by the elastic member 5 is the X direction. The description of the absorbent body 14 provided with the surface material 15 will be described later. Hereinafter, the description of the disposable pants 10 will be continued with reference to FIGS.
As described above, the exterior sheet 11 includes the first fibrous sheet 2, the fiber material 4, and the second fibrous sheet 3 from the skin surface side in contact with the user's skin, and the printed layer 4 a of the fiber material 4. Is printed, and a pattern is applied to the body mounting portion 12 and its periphery in FIGS. 7, 8, and 12. In addition, you may make it give a pattern to the whole exterior sheet | seat 11 by making the whole fiber material 4 into the printing layer 4a. In this embodiment, since the inside of the 2nd fibrous sheet 3 is the fiber material 4, it is easy to see the printing layer 4a of the disposable pants 10 when it visually recognizes from the outside.

As described above, the body mounting portion 12 is formed by bending both ends of the exterior sheet 11 in the X direction. For this reason, the elastic member 5 (linear elastic body 5a) is densely arranged compared to other parts, and the elastic force acting on the waist of the user is stronger than the other parts. When the pants 10 are worn, the disposable pants 10 are difficult to shift downward.
The hook-and-loop fastener 13 has a rectangular shape whose longitudinal direction is the X direction, and two hook fasteners are provided along the Y-direction, for a total of four. It attaches to the trunk | drum mounting part 12 so that attachment or detachment is possible. In the present embodiment, the hook-and-loop fastener 13 is formed across the inner side of the body mounting part 12 and the inner side of the exterior sheet 11, but may be accommodated inside the body mounting part 12. The surface fastener 13 may be bonded by hot melt bonding, ultrasonic bonding, or heat seal bonding. Note that an adhesive such as a double-sided tape may be used in place of the hook-and-loop fastener 13, or the other end side body mounting portion 12 may be engaged by mechanical engagement.

The adjustment part 16 is an end part in the Y direction where the hook-and-loop fastener 13 is provided and its periphery, and the disposable pants 10 are used by pinching this part with a finger and joining it to the body part mounting part 12 on the other end side. It is a part that adjusts according to the person's body shape.
FIG. 11 is a diagram illustrating a wearing state of the disposable pants 10 of the present embodiment. In conventional open-type disposable diapers, it is assumed that babies and care recipients will wear a disposable diaper while sleeping, and a conventional open-type disposable diaper will be used while the user is standing or sitting. It was difficult to wear, and it was not easy to adjust the tape part according to the body shape. In addition, the conventional disposable pants were easy to wear while standing in the same way as normal pants, but they can only be fitted to the user's waist with the rubber of the waist, and can be fitted to the buttocks There wasn't.

First, as shown in FIG. 11, the disposable pants 10 of the present embodiment are joined to the body mounting portion 12 on the other end side to form a pants-type shape. In this state, the user wears (wears) the disposable pants 10 while standing in the same manner as normal pants or sitting on a chair. That is, the disposable pants 10 can be easily worn (mounted) in the same manner as normal pants.
FIG. 12 is a diagram of the doll worn with the disposable pants 10 of the present embodiment. After the user wears (wears) the disposable pants 10, the user adjusts the position of the hook-and-loop fastener 13 in accordance with the body shape of the user using one (for example, the right side) adjusting portion 16, that is, the one hook-and-loop fastener 13. . For example, if the hook-and-loop fastener 13 is adjusted along the Y direction, the waist size can be adjusted by the expansion and contraction of the elastic member 5, and if the hook-and-loop fastener 13 is adjusted along the X direction and the elastic member 5 is expanded and contracted, the buttocks The size of the circumference (arrow A) can be adjusted. Furthermore, if the hook-and-loop fastener 13 is adjusted in an oblique direction (for example, an obliquely upward right direction in the drawing), the dimensions of the waist and the hips can be adjusted at a time. As can be seen from FIG. 12, it can be seen that the disposable pants 10 of this embodiment are fitted to the figure of the doll. That is, the disposable pants 10 of the present embodiment can be fitted according to the body shape of each user.

Further, when the user is an infant or a care recipient who can stand, if the user wears the disposable pants 10 and lowers the disposable pants 10 downward (the X direction in the figure), it will be described later. The state of the absorber 14 can be confirmed, and the necessity of replacement of the absorber 14 can be easily confirmed. Since the absorber 14 can be replaced while the user is standing or sitting, the disposable pants 10 that are easy to use can be realized. Moreover, since the disposable pants 10 can endure several times of washing, it can be used for a certain period of time if the absorbent body 14 is replaced, which is economical.
In addition, the disposable pants 10 of this embodiment can be used regardless of age, sex, and body shape (for children, men, women, etc.), and can also be applied to animals such as pets.

FIG. 18 is a flowchart illustrating a method for manufacturing the disposable pants 10 according to the present embodiment. Hereinafter, the method for manufacturing the disposable pants 10 will be described with reference to this flowchart.
The manufacture of the disposable pants 10 is executed under the control of a control device (not shown) having a factory factory CPU. In step S1, the dough 1 is manufactured as described above.
In step S 2, the fabric 1 is cut with a cutting machine (not shown) according to the size of the disposable pants 10, and cut so that the central portion has a concave shape.
In step S3, both ends of the cut fabric 1 are bent, and the bent portions are bonded using various bonding methods such as ultrasonic bonding and hot melt bonding. Thereby, the trunk | drum mounting part 12 is formed in the both ends of the fabric | dough 1. FIG.
In step S4, the surface fastener portion is manufactured by joining the surface fastener 13 to the body portion mounting portion 12 using various joining methods such as ultrasonic joining and hot melt joining. In addition, what is necessary is just to set the magnitude | size and the number of the hook_and_loop | surface fasteners 13 suitably.

Next, description of the absorber 14 provided with the surface material 15 shown in FIG. 10 will be continued. For example, an adhesive tape is provided on the attachment surface opposite to the skin surface of the absorbent body 14 (for example, two places) and can be attached to and detached from the disposable pants 10 described above. As described above, the surface material 15 is manufactured by cutting the dough 1.
FIG. 13 is a view in which the surface material 15 is attached to the absorber of the present embodiment, FIG. 14 is a partially enlarged view of the surface material 15 of the present embodiment, and FIG. 15 corresponds to FIGS. FIG. Hereinafter, the description will be continued with reference to FIGS.

The absorbent body 14 provided with the surface material 15 has a gather part 21 provided on the skin surface side and a film part 28 provided on the side (outside) opposite to the skin surface side. As will be described later with reference to FIGS. 16 and 17, the gather portion 21 will be described first.

The gather part 21 includes a gather 17, an inner joint part 18, an inner collar part 19, and an end joint part 20.
The gather 17 prevents lateral leakage of urine in the Y direction, and an elastic member similar to the elastic member 5 is provided on the nonwoven fabric. In the present embodiment, two gathers 17 provided with elastic members are prepared.
The inner joint portion 18 joins the gather portion 21 and the surface material 15 in order to provide the two gathers 17 in the vicinity of both ends of the surface material 15 on the Y side. Any joining method may be used for joining by the inner joining portion 18, but in this embodiment, ultrasonic joining is performed.

The description of the formation of the gathered portion 21 on the upper side (+ Y side) shown in FIGS. 14 and 15 is continued.
As is clear from FIG. 15, the absorption portion 22 of the present embodiment has a concave shape at the center. In order to join the gather part 21 and the skin surface side of the surface material 15 outside the concave shape, the surface material 15 (indicated by a dotted line in FIG. 15) expands and contracts in the X direction on the outside (+ Y direction) of the inner joint 18 ) Is present but the absorbing portion 22 is not present. For this reason, the inner side collar part 19 by the elasticity of the elastic member 5 is formed by joining the edge part 20 of the gather part 21, and the edge part 27 (refer FIG. 16, FIG. 17) of the film part 28 mentioned later. For this reason, the inner collar part 19 expands and contracts in the X direction. The formation of the inner flange portion 19 is the same as the formation principle of the flange portion 6 described above. In addition, although what kind of joining method may be used for joining the edge part 20 of the gather part 21, and the edge part 27 of the film part 28, in this embodiment, it shall join by heat sealing | fusion.
The lower gather portion 21 shown in FIG. 13 is also formed in the same manner as described above.

The absorption part 22 is a well-known thing which absorbs liquids (including body fluids, such as blood), such as sweat and urine of a disposable diaper wearer. Since the absorber 14 absorbs excrement, it is desirable to add a deodorant to the absorber 22. As the deodorant, activated carbon, zeolite, silica, ceramic, Oya stone, charcoal polymer, carbon nanotube, carbon nanohorn, organic acid such as citric acid and succinic acid, and alum (potassium alum) can be used.
This absorption part 22 is laminated | stacked (mounted) on the inner surface of the film 24 used as an exterior body. That is, in the state where the absorbing portion 22 is placed on the inner surface of the film 24, the end portion 20 of the gather portion 21 and the end portion 27 of the film portion 28 are joined as described above.

16 is a diagram showing the outside of the absorber 14, and FIG. 17 is a schematic diagram of the absorber 14 corresponding to FIG. As shown in FIGS. 16 and 17, the film portion 28 includes a film 24, an outer joint portion 25, an outer flange portion 26, and an end portion 27. As described above, the absorption portion 22 has a concave shape at the center. The description of the formation of the upper film portion 28 will be continued.

The film 24 is a well-known air-permeable film that does not transmit liquid but allows vapor to pass therethrough, and an absorption part 22 whose center is formed in a concave shape is supplied to the inside of the film 24.
The outer bonding portion 25 is formed by bonding the film 24 and the surface material 15 by ultrasonic bonding or hot melt bonding so as to cover the absorbing portion 22.

A surface material that expands and contracts in the X direction on the outer side (+ Y direction) of the outer joint portion 25 in order to join the film portion 28 and the back surface side (non-skin surface side) of the surface material 15 outside the concave shape of the absorbing portion 22. 15 (indicated by a dotted line in FIG. 15) exists, but the absorbing portion 22 does not exist. For this reason, as described above, the outer flange portion 26 is formed by the elasticity of the elastic member 5 by joining the end portion 20 of the gather portion 21 and the end portion 27 of the film portion 28 described later. For this reason, the outer collar part 26 expands and contracts in the X direction. The formation of the outer flange portion 26 is the same as the principle of forming the flange portion 6 described above. As is clear from FIGS. 16 and 17, the film portion 28 is also formed on the lower side. The lower film portion 28 is formed in the same manner as described above.

As shown in FIGS. 14 and 15, the surface material 15 and the absorbing portion 22 are partially joined along the X direction by a plurality of surface material coupling portions 23. In the present embodiment, the intermittent bonding between the surface material 15 and the absorbing portion 22 is performed by ultrasonic bonding. Instead of joining the surface material 15 and the absorbing portion 22, the surface material 15 and the absorbing portion 22 may be pressed by embossing in a state where the surface material 15 is provided on the absorber 14. By joining or pressing the surface material 15 and the absorbing portion 22, the non-skin surface of the surface material 15 (for example, the fiber material 4 having excellent liquid permeability) and the absorbing portion 22 come into contact with each other, and urine is collected. In order to promptly lead to the absorption part 22, the surface material 15 is smooth by ventilation by the space 9 shown in FIG. Furthermore, the surface area of the laminated sheet 30 is increased as compared with the case where the elastic member 5 is not provided, and even when the amount of urine is large, the urine can be promptly guided to the absorption part 22. Furthermore, since the elastic force of the elastic member 5 is not lost, the feeling of fitting and wearing is not reduced.

Furthermore, since a plurality of surface material bonding portions 23 are provided at predetermined intervals in the Y direction, urine is prevented from entering in the Y direction, so that the side leakage of urine is prevented by the surface material bonding portion 23. You can also.
In the disposable pants 10 of this embodiment, the absorbent body 14 provided with the surface material 15 is detachably joined to the exterior sheet 11 with a tape or the like. As is clear from FIGS. 9 and 10, the exterior sheet 11 is stretched in the Y direction by the elastic member 5, and thus can fit the user's waist and buttocks as described above. On the other hand, since the surface material 15 is expanded and contracted in the X direction by the elastic member 5, the elastic force of the elastic member 5 acts on the portion contacting the user's crotch, and the surface material 15 fits the user. Furthermore, since the elastic force acts when the absorber 14 is likely to shift downward due to the weight of urine, the absorber 14 can be prevented from shifting.

FIG. 19 is a flowchart showing a method for manufacturing the absorber 14 provided with the surface material 15 of the present embodiment. The absorber 14 is manufactured under the control of a control device (not shown) having a factory factory CPU. In step S11, the dough 1 is manufactured as described above.
In step S 12, the surface material 15 is manufactured by cutting the dough 1 according to the size of the absorber 14.
In step S 13, an elastic member is joined to the non-woven fabric to produce the gather 17.
In step S14, the gather 17 manufactured in step S13 is joined to the surface material 15. Thereby, the inner side joint part 18 is formed.

In step S 15, the absorption part 22 having the center formed (formed) in the recess is supplied to the inside of the film 24.
In step S 16, the outer joint portion 25 is formed by joining the surface material 15 and the film 24 so as to cover the absorbing portion 22.
In step S17, the end portion 20 of the gather portion 21 and the end portion 27 of the film portion 28 are joined by, for example, heat sealing. Instead of joining the end 20 of the gather part 21 and the end 27 of the film part 28, either one of the end 20 or the end 27 is bent to the other, and then hot-melt joining or the like. You may make it join the gather part 21 and the film part 28. FIG.

In step S18, the surface material 15 and the absorbing portion 22 are partially joined along the X direction to form the plurality of surface material coupling portions 23 along the X direction. Instead of partial joining, mechanical pressing such as embossing may be used. Thereby, the absorber 14 provided with the surface material 15 can be manufactured. Note that the flowchart of FIG. 19 is merely an example, and the order of each step and the like may be appropriately changed depending on manufacturing convenience.
