Hereinafter, embodiments of the disposable functional fabric material and the method for producing the fabric according to the present invention will be described. The embodiments described herein are merely examples for implementing the present invention. The present invention is not limited to what is described in the following embodiments.

[First Embodiment]
FIG. 1 is a cross-sectional view of a disposable functional fabric material 100. As shown in FIG. 1, the disposable functional fabric material 100 of the first embodiment is disposed between the first nonwoven fabric layer 10, the second nonwoven fabric layer 20, the first nonwoven fabric layer 10, and the second nonwoven fabric layer 20. And a laminated sheet 60 having a paper sheet 40 that can form the printed layer 30 and an adhesive layer 50 that bonds the second nonwoven fabric layer 20 and the paper sheet 40.
Since the disposable functional fabric material 100 has the elastic member 70 disposed between the first nonwoven fabric layer 10 and the paper sheet 40, the laminated sheet 60 can be expanded and contracted. Furthermore, in the disposable functional fabric material 100, a non-adhesive portion 80 where the second nonwoven fabric layer 20 and the paper sheet 40 are not bonded is formed on at least a part of the adhesive layer 50. In the non-bonding part 80, a space is formed between the second nonwoven fabric layer 20 and the paper sheet 40. The area ratio of the non-bonded portion 80 is 5 to 85% with respect to the area of the second nonwoven fabric layer 20.
Here, in this specification, “nonwoven fabric” refers to a fabric other than a fabric made by weaving fibers vertically and horizontally. In this case, “fibers” include natural fibers (plant fibers (cellulose polymers), animal fibers (protein polymers), etc.), refined fibers (lyocell, tencel, etc.), regenerated fibers such as rayon, viscose, etc. Chemical fibers such as semi-synthetic fibers such as acetate and synthetic fibers such as nylon are all included. These fibers are appropriately selected according to the application used. Moreover, the fiber used for a nonwoven fabric may be used individually by 1 type, and 2 or more types may be used together.
In the present specification, the term “disposable” includes not only those that are discarded after a single use, but also those that can withstand short-term use and several washings depending on the intended use and purpose.

<First nonwoven fabric layer>
In FIG. 1, the nonwoven fabric used for the 1st nonwoven fabric layer 10 can be suitably selected according to the product and use to which the disposable functional fabric material 100 is applied. For example, when the disposable functional fabric material 100 is used as a fabric in a disposable garment and the first nonwoven fabric layer 10 is on the wearer's body when worn, the first nonwoven fabric layer 10 is flexible and soft to the touch. In addition to water absorption (sweat), etc., it is preferable to use a nonwoven fabric made of a material that can exhibit various functions according to the use of various products. On the other hand, when the 1st nonwoven fabric layer 10 does not become a wearer's or a user's body side, importance is attached to functions (for example, waterproofness) different from the above, and the nonwoven fabric used for the 1st nonwoven fabric layer 10 from that viewpoint (for example, , Waterproof nonwoven fabric) may be selected.

<Second non-woven fabric layer>
In FIG. 1, the nonwoven fabric used for the 2nd nonwoven fabric layer 20 can be suitably selected according to the product and use to which the disposable functional fabric material 100 is applied.
The disposable functional fabric material 100 according to the first embodiment can efficiently display various designs and messages by visually recognizing prints and the like formed on the paper sheet 40 through the second nonwoven fabric layer 20. Can be expressed effectively. From this point of view, it is preferable to select a material for the nonwoven fabric used for the second nonwoven fabric layer 20 so that printing or the like formed on the paper sheet 40 can be properly recognized from the outside. Furthermore, the nonwoven fabric used for the second nonwoven fabric layer 20 is a process that draws out higher design and aesthetics as a whole fabric in cooperation with printing formed on the paper sheet 40, formation of the adhesive layer 50 described later, and the like. It is also preferable to select from the viewpoint that it becomes possible.

Also, when the disposable functional fabric material 100 of the first embodiment is used as a product such as disposable clothing, the second nonwoven fabric layer 20 is rarely disposed on the side in contact with the wearer's skin. However, when the disposable functional fabric material 100 is used as a product of a disposable bedding (for example, a bed sheet or the like), the second nonwoven fabric layer 20 is often disposed on the side in contact with the user's skin. When the second non-woven fabric layer 20 is in direct contact with the human body, the second non-woven fabric layer 20 can exhibit various functions in addition to flexibility, touch properties, water absorption (sweat) properties, etc., depending on the application of the product. It is preferable that the material is a nonwoven fabric.

<Paper sheet>
In FIG. 1, as the paper sheet 40, pulp paper or a paper material formed from a material whose main raw material is pulp can be used. That is, as the paper sheet 40, a paper material manufactured by subjecting a base paper sheet as a raw material sheet to processing in a plurality of steps can be used. When the paper sheet 40 is formed from a material mainly composed of pulp, the pulp content is preferably 30% or more, and more preferably 50% or more. Further, the blending of the pulp is more preferably 80% or more. By setting the blending ratio of the pulp as described above, the disposable functional fabric material 100 can improve the flexibility as a whole or improve the production efficiency at the time of manufacture. Moreover, when the blending of the pulp is increased, after the disposable functional dough material 100 is discarded, the waste is easily decomposed, for example, in the soil. Therefore, when the blending of the pulp is increased, the environmental load can be further reduced, and consideration for the environment can be further improved. The paper sheet is preferably composed of a single sheet (single layer), but may be composed of a plurality of sheets (multiple layers). When the paper sheet 40 is composed of a plurality of sheets of paper, the thickness, material, etc. of each other may be the same, or two or more types may be used in combination.
The preferred basis weight of the paper sheet 40 varies depending on the material, but as an example, if it is a single layer, 7 to 50 g / m ² is preferable, and 10 to 30 g / m ² is more preferable.

As shown in FIG. 1, the printing layer 30 is formed on a paper sheet 40. In the disposable functional fabric material 100 of the first embodiment, the printing layer 30 is formed on the paper sheet 40 instead of the nonwoven fabric. Therefore, the disposable functional fabric material 100 can easily and efficiently create a clear pattern. Therefore, the disposable functional fabric material 100 can express various designs and messages efficiently and effectively. In particular, by appropriately selecting the design and pattern to be printed on the paper sheet 40, the selection of the nonwoven fabric used for the second nonwoven fabric layer 20, the formation method of the adhesive layer 50, etc., the overall fabric has high design and aesthetics. A functional fabric material 100 can be provided. Examples of the design and pattern to be printed on the paper sheet include aesthetic colors, patterns, photographs, and the like (hereinafter also referred to as “photographs”).

For example, a photograph or the like can be printed on the paper sheet 40 by a technique such as inkjet or flexographic printing. For example, a varnishing process or a binder may be added to the surface of the printing layer 30 as a color fading prevention process. Examples of the binder include known materials such as PVA, CMC, EVA, acrylic, and lacquer. Further, ink that has been subjected to color fading prevention processing can also be used for printing.
A thin paper sheet 40 is preferable because the printing layer 30 can be formed by flexographic printing. The flexographic printing method has advantages such as a small contact area between the plate and the paper sheet 40 and a low printing pressure. For this reason, when flexographic printing is used, the paper sheet 40 is easily peeled off from the plate. In particular, when the paper sheet 40 is thin, the printing layer 30 is suitable. In flexo printing, there are many types of ink that can be used. For this reason, in particular, compared to the ink jet printing method in which ink is ejected through a nozzle or the like, there are few adverse effects such as being restricted by the viscosity of the ink, and the degree of freedom is high. In addition, although the aspect which forms the printing layer 30 in the paper sheet 40 based on FIG. 1 was described here, the disposable functional material 100 of 1st Embodiment is not limited to this. For example, the disposable functional fabric material 100 having high aesthetics can be provided by using colored paper or the like as the paper sheet 40 and performing wrinkle processing or the like as described later.

In the disposable functional fabric material 100, it is also preferable to use a wrinkled paper sheet 40. In the paper sheet 40, the wrinkle processing method is not particularly limited. For example, by providing the paper sheet 40 with a concave or convex shape using an embossing roll, a three-dimensional design that cannot be expressed only by printing such as a design, a design with different nuances depending on the viewing angle, and the like can be expressed.
Moreover, it is also preferable to form an appropriate hole in the paper sheet 40 by hole forming processing such as punching and punching using an embossing roll or the like. Furthermore, it is also preferable to use a embossing roll or the like to subject the paper sheet 40 to a fissure or a cut process. In addition, it is preferable to stretch the paper sheet 40 by pressing with an embossing roll or the like. By applying these processes to the paper sheet 40, it is possible to provide a disposable functional fabric material 100 that is flexible and excellent in plumpness as a whole.
Furthermore, since the disposable functional fabric material 100 of the first embodiment uses the paper sheet 40, the air permeability is good and the stuffiness is suppressed. In addition, the disposable functional fabric material 100 has heat retention because the paper sheet 40 contains a lot of air. Furthermore, since the paper sheet 40 has a small frictional voltage, it is possible to suppress the occurrence of crackling noise by clinging to static electricity during use or wearing.

<Elastic member>
As shown in FIG. 1, an elastic member 70 is disposed between the first nonwoven fabric layer 10 and the paper sheet 40. Therefore, the laminated sheet 60 can be expanded and contracted. As the elastic member 70, rubber based on urethane, silicon or the like, rubber made of other synthetic materials, natural rubber, other elastic materials, or the like can be used. In FIG. 1, the elastic member 70 is arrange | positioned between the 1st nonwoven fabric layer 10 and the paper sheet 40 by adhesion | attachment using a hot-melt-adhesive.

The hot melt adhesive is not limited to a specific adhesive. As the hot melt adhesive, known adhesives such as EVA (ethylene vinyl acetate copolymer), PO (polyolefin), PA (polyamide), SR (synthetic rubber), ACR (acrylic), A PUR (polyurethane, moisture-curing type) system or the like can be used. These adhesives may be used individually by 1 type, and may use 2 or more types together.

As a method for applying the hot melt adhesive, continuous coating, intermittent coating, stripe coating, spiral coating, block coating, pattern coating, or the like can be used. The elastic member 70 is preferably bonded with a hot melt adhesive in a state of being appropriately disposed between the first nonwoven fabric layer 10 and the paper sheet 40. Moreover, in order to fix the 1st nonwoven fabric layer 10 and the paper sheet 40 more stably, and for the improvement of a design property, etc., a hot melt adhesive is apply | coated by various pattern application | coating etc., and the 1st nonwoven fabric layer 10 It is also preferable that the paper sheet 40 is bonded.

<Adhesive layer>
In the disposable functional fabric material 100 of the first embodiment, a non-adhesive portion 80 where the second nonwoven fabric layer 20 and the paper sheet 40 are not bonded is formed on at least a part of the adhesive layer 50. FIG. 2 is a conceptual diagram for explaining a space formed between the second nonwoven fabric layer 20 and the paper sheet 40. As shown in FIG. 2, a space is formed between the second nonwoven fabric layer 20 and the paper sheet 40 in the non-adhesive portion 80. The area ratio of the non-bonded portion 80 is 5 to 85% with respect to the area of the second nonwoven fabric layer 20. The area ratio is preferably 10 to 80%, more preferably 30 to 75% with respect to the area of the second nonwoven fabric.

As described above, the disposable functional fabric material 100 according to the first embodiment has the non-adhesive portion 80 where the second nonwoven fabric layer 20 and the paper sheet 40 are not adhered, and therefore the second nonwoven fabric layer 20 and the paper sheet. A space is formed between 40. In this way, by appropriately forming a space between the second nonwoven fabric layer 20 and the paper sheet 40, it is possible to express a bulkiness that cannot be expressed only by printing on paper. In addition, by appropriately forming a space, a three-dimensional and nuanced design can be effectively applied, and the flexibility and fluffiness of the entire fabric can be expressed. In particular, by appropriately selecting and adjusting the design and pattern to be printed on the paper sheet 40, the selection of the nonwoven fabric used for the second nonwoven fabric layer 20, the formation method of the adhesive layer 50 (that is, the formation method of the space), etc., the entire fabric As a result, design and aesthetics can be improved. In addition, when bonding with a hot-melt adhesive is performed, the original goodness of the fabric is not utilized in the bonded portion, and the air permeability is deteriorated. In this respect, since the non-adhesive portion 80 to which the hot melt adhesive is not applied is formed in the fabric of the first embodiment, the original goodness of the fabric can be utilized and air permeability can be secured.

Examples of the hot melt adhesive coating method for bonding the second nonwoven fabric layer 20 and the paper sheet 40 include continuous coating, intermittent coating, stripe coating, spiral coating, block coating, pattern coating, and pattern coating. . In the first embodiment, the second nonwoven fabric layer 20 and the paper sheet 40 may be bonded by any one of these coating methods, or may be bonded by appropriately combining these coating methods. Moreover, since the ratio of the space formed generally becomes smaller as the application area of the adhesive is increased, the flexibility of the fabric, the feeling of plumpness of the entire fabric, and the like are suppressed. On the other hand, as the adhesive application area is increased, the design and pattern printed on the paper are more clearly visible from the outside. Moreover, since the ratio of the space formed becomes large, so that the application | coating area of an adhesive agent is made small, the softness | flexibility of cloth | dough, the fullness feeling of the whole cloth | dough, etc. become more excellent. On the other hand, as the adhesive application area is reduced, the design and pattern printed on the paper are visually recognized as a more blurred design and pattern from the outside. Also, if the hot melt adhesive is applied by pattern application, etc., the design printed on the paper sheet 40 and the synergistic effect of this pattern will give a design with different nuances depending on the viewing angle that cannot be obtained by printing alone. Can express.

In the first embodiment, the area ratio of the non-bonding portion 80 is 5 to 85% with respect to the area of the second nonwoven fabric layer 20. The area ratio is preferably 10 to 80%, more preferably 30 to 75% with respect to the area of the second nonwoven fabric.
If the area ratio of the non-adhesive portion 80 in the second nonwoven fabric layer 20 is within the above range, the fabric flexibility, the feeling of plumpness of the entire fabric, etc. are excellent, and the nuance depends on the viewing angle, which cannot be obtained only by printing on paper. It is possible to suitably express such a different design.

Hereinafter, an example of a method for efficiently producing the disposable functional fabric material 100 of the first embodiment will be described. However, the manufacturing method of the disposable functional fabric material 100 of the first embodiment is not limited to the following description.
First, a printed layer 30 having a design or pattern is formed on the paper sheet 40. Thereafter, the paper sheet 40 is subjected to shape processing by wrinkle processing (processing with an embossing roll or the like). Thereafter, the second nonwoven fabric layer 20 is bonded to the paper sheet 40 via an adhesive layer 50 formed by hot melt bonding or the like. Thereby, the second nonwoven fabric layer 20 is laminated on the paper sheet 40.

Here, at least a part of the adhesive layer 50 is formed with a non-adhesive portion 80 where the second nonwoven fabric layer 20 and the paper sheet 40 are not adhered. Therefore, a space is suitably formed between the second nonwoven fabric layer 20 and the paper sheet 40. Thus, by effectively forming a space between the second nonwoven fabric layer 20 and the paper sheet 40, it is bulky and three-dimensional that cannot be expressed only by printing on paper, and has different nuances depending on the viewing angle. Design can be applied effectively. Moreover, by forming a space effectively between the second nonwoven fabric layer 20 and the paper sheet 40, the flexibility and fluffiness of the entire fabric can be expressed. Furthermore, by forming the non-adhesive portion 80, the original texture of the fabric can be utilized and air permeability can be ensured.

Thereafter, the laminate of the second nonwoven fabric layer 20 and the paper sheet 40 is passed between a pair of flat rolls (not shown) as necessary. If the laminated body of the 2nd nonwoven fabric layer 20 and the paper sheet 40 is passed between a pair of plane rolls, the 2nd nonwoven fabric layer 20 and the paper sheet 40 will be pressed by a pair of plane rolls. Next, the elastic member 70 is bonded to the opposite side of the paper sheet 40 (the side opposite to the adhesive layer 50) with a hot melt adhesive in a tensioned state. Furthermore, the 1st nonwoven fabric layer 10 is adhere | attached on the reverse side of the paper sheet 40 with a hot-melt-adhesive, and the laminated sheet 60 is obtained. Furthermore, the laminated sheet 60 of the first embodiment can be efficiently manufactured by releasing the tension of the elastic member 70 after the entire laminated sheet 60 obtained is pressed between a pair of flat rolls. By passing the obtained laminated sheet 60 a plurality of times between rolls (flat rolls, etc.), the disposable functional fabric material 100 of the first embodiment having a softer texture can be efficiently produced.

Disposable functional fabric material 100 can be provided to patients and customers in hospitals, clinics, relaxation facilities, accommodation facilities, etc., as well as disposable clothing, various miscellaneous goods, bedding, etc. It can be suitably used as a material for various uses and products.

The disposable functional fabric material 100 of the first embodiment may be further processed to give additional functions depending on the application and product to be applied. For example, it is also preferable to use agents that exhibit various functions such as deodorants, insect repellents, fragrances, waterproofing agents, antifouling agents, and antibacterial agents, which will be described later, depending on the application and product. These chemical | medical agents may be apply | coated to a nonwoven fabric layer (10, 20), and may be previously kneaded in the fiber which comprises a nonwoven fabric. Moreover, these chemical | medical agents may be apply | coated to the paper sheet 40, and in the papermaking process which produces paper, you may make it paper-form by making it contain previously in water. Furthermore, when forming the printing layer 30, you may mix these chemical | medical agents with an ink previously. Among these, a method of mixing a medicine in ink in advance is more preferable because the disposable functional fabric material 100 can be efficiently manufactured.

(Second Embodiment)
Next, a disposable functional fabric material and a method for producing the fabric according to the second embodiment will be described. In the second embodiment, the fabric 1 is used as the exterior sheet 11 (see FIG. 12) of the disposable pants 13 that are disposable products. In addition, the fabric 1 can also be used as a surface material for disposable diapers, disposable pants 13, and their absorbent bodies 14 (absorbing pads).

FIG. 3 is a diagram illustrating a surface state of the dough 1 according to the second embodiment. FIG. 4 is a view showing the heel part 6 of the dough 1. FIG. 5 is an enlarged view of the dough 1.
In FIG. 3, 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. FIG. 3 shows an aspect in which a large number of uneven surfaces are formed on the fabric 1 by a large number of elastic members 5. As shown in FIG. 4, a large number of flanges 6 are repeatedly formed along the y direction by the large number of uneven surfaces. As is apparent from FIGS. 3 and 4, the elastic member 5 is provided along the x direction. The elastic member 5 is a member that applies an elastic force in the x direction to the fabric 1. A plurality of elastic members 5 are provided at predetermined intervals in the y direction, which is the short direction (second direction).

In the first embodiment, a linear elastic body 5 a having stretchability is used as the elastic member 5. As the linear elastic body 5a, for example, a synthetic material based on urethane or silicon, natural rubber, or the like can be used.
When a lattice-shaped elastic member is used, a large number of flanges 6 can be formed with 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, for example, a stretchable elastic film such as a urethane film, a silicon film, or an elastomer film can be used.
In the second embodiment, an example in which polyurethane is used as the linear elastic body 5a will be described.

FIG. 6 is a cross-sectional view taken along line AA in FIG. FIG. 7 is a sectional view taken along line BB in FIG. As shown in FIGS. 6 and 7, the fabric 1 is constituted by a laminated sheet 15. The laminated sheet 15 is a laminated body of the first fibrous sheet 2, the second fibrous sheet 3, and the fiber sheet 4. Each of the first fibrous sheet 2 and the second fibrous sheet 3 is a sheet having air permeability. The fiber sheet 4 is a sheet having liquid diffusibility. The fiber sheet 4 is disposed between the first fibrous sheet 2 and the second fibrous sheet 3. The 1st fibrous sheet 2 and the 2nd fibrous sheet 3 comprise the fiber layer which has air permeability. The fiber sheet 4 constitutes a fiber layer having liquid diffusibility. Thus, the lamination sheet 15 is comprised from 3 layers. When the fabric 1 is applied to the exterior sheet 11 of the disposable pants 13 as in the second embodiment, the first fibrous sheet 2 is arranged on the side in contact with the user's skin (skin surface side). Moreover, the 2nd fibrous sheet 3 is located in the outer side (outer surface side).

In the second embodiment, the first fibrous sheet 2 is a nonwoven fabric. As this nonwoven fabric, for example, a two-layer or three-layer spunbond nonwoven fabric can be used. When the first fibrous sheet 2 is used on the skin surface of the exterior sheet 11 (see FIG. 12) of the disposable pants 13, 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.
The basis weight of the first fibrous sheet 2 is preferably 10 to 50 g / m ² as an example, and more preferably 10 to 20 g / m ² from the viewpoint of manufacturing cost. However, the basis weight of the first fibrous sheet 2 is not limited to this.

In the second embodiment, the second fibrous sheet 3 is a nonwoven fabric. As this nonwoven fabric, for example, a two-layer or three-layer spunbond nonwoven fabric can be used. When the second fibrous sheet 3 is used on the outer surface of the exterior sheet 11 of the disposable pants 13, it is desirable to use a water-repellent sheet. As the water-repellent nonwoven fabric, a three-layer spunbond nonwoven fabric can be used. The water-repellent nonwoven fabric is preferably subjected to a water-repellent treatment in which a silicon-based, paraffin metal-based, alkylchromic chromoid-based water repellent or the like is coated. The basis weight of the water-repellent nonwoven fabric is preferably 10 to 50 g / m ² as an example, and more preferably 10 to 20 g / m ² from the viewpoint of production cost. However, the basis weight of the water-repellent nonwoven fabric is not limited to this.

When the paper material is used for the fiber sheet 4, a paper material formed from pulp paper or a material mainly made of pulp can be used. As the raw material pulp, for example, wood pulp, synthetic pulp, waste paper pulp and the like can be used. Further, not only natural fibers such as pulp, but also regenerated fibers such as rayon can be used. The basis weight of the fiber sheet 4 is preferably 10 to 50 g / m ² as an example. Moreover, when using a paper material as the fiber sheet 4, in order to give a softness | flexibility, it is preferable to give an embossing, for example.

As shown in FIG. 7, in the second embodiment, the first fibrous sheet 2 and the fiber sheet 4 are joined by an adhesive 17 applied to the peripheral surface of the elastic member 5. Therefore, a non-adhesive portion 8 where the adhesive 17 does not exist is formed between the first fibrous sheet 2 and the fiber sheet 4 in a portion where the elastic member 5 does not exist. A space 9 is formed in the non-bonding portion 8. Since the space 9 by the non-bonding part 8 is formed in the cloth 1 of the second embodiment, each function of moisture transpiration, heat dissipation, and moisture permeability is improved. Note that the adhesive 17 is partially (intermittently) applied to at least one of the first fibrous sheet 2 and the fiber sheet 4 in place of or via the elastic member 5 in place of the adhesive via the elastic member 5. May be applied to join the first fibrous sheet 2 and the fiber sheet 4 together. Also in this case, since the first fibrous sheet 2 and the fiber sheet 4 are joined partially (intermittently), a space 9 is formed between the first fibrous sheet 2 and the fiber sheet 4. Is done.

When the 1 m ² first fibrous sheet 2 and the fiber sheet 4 are joined by the adhesive 17 applied to the peripheral surface of the elastic member 5, the elastic members 5 are arranged at intervals of 5 mm, and 200 elastic members 5 is required. When 0.02 to 0.04 g / m of the adhesive 17 is applied to the elastic member 5 in a state where the elastic member 5 is extended, the amount of the adhesive 17 becomes 4 to 8 g / m ² .
If the elastic members 5 are arranged at intervals of 10 mm, 100 elastic members 5 are required. When 0.03 to 0.07 g / m of the adhesive 17 is applied to the elastic member 5 in a state where the elastic member 5 is stretched, the amount of the adhesive 17 becomes 3 to 7 g / m ² .

The cloth 1 is expanded and contracted by the elastic member 5 in the x direction of FIG. Moreover, when the fabric 1 is used as the exterior sheet 11 of the disposable pants 13, the disposable pants 13 can be used repeatedly if the absorbent body 14 (see FIG. 12) is removable.
Therefore, when the amount of the adhesive 17 is less than 3 g / m ² , the bonding between the first fibrous sheet 2 and the fiber sheet 4 may be peeled off. Therefore, it is preferable to join the first fibrous sheet 2 and the fiber sheet 4 using an adhesive 17 of 4 g / m ² or more. In addition, when the absorber 14 (not shown) is a fixed type, the disposable pants 13 are basically discarded by one excretion. In this case, if the amount of the adhesive 17 is 3 g / m ² or more, it can be used as the disposable pants 13.

On the other hand, when the amount of the adhesive 17 exceeds 8 g / m ² , the expansion and contraction of the elastic member 5 may be reduced, or the softness of the fabric 1 may be lost. In that case, the convenience of the disposable pants 13 is deteriorated. When the adhesive 17 is a hot melt adhesive, in addition to the cost of the hot melt adhesive, an electricity bill for heating the hot melt adhesive is also required. Therefore, when the adhesive 17 is a hot melt adhesive, the amount of the adhesive 17 is more preferably 7 g / m ² .

The second fibrous sheet 3 and the fiber sheet 4 are joined by applying the adhesive 7 partially (intermittently). When the application amount and the application area of the adhesive 7 are increased, the softness of the fabric 1 is lost and becomes hard. For this reason, when the fabric 1 is used as the disposable pants 13, the wearing comfort is deteriorated. Therefore, when the 1 m ² second fibrous sheet 3 and the fiber sheet 4 are joined, the application amount of the adhesive 7 applied by the first adhesive application device 203 (see FIG. 8) is set to 0.8 to 2.2 g / m ² , preferably 1.0 to 1.5 g / m ² . If it is less than the lower limit of 0.8 g / m ² , the second fibrous sheet 3 and the fiber sheet 4 are easily peeled off. On the other hand, when the upper limit of 2.2 g / m ² is exceeded, the softness of the fabric 1 is lost as described above. In order to provide a softer fabric 1, it is preferable that the upper limit value of the application amount of the adhesive 7 is 1.5 g / m ² .

As described above, the application amount of the adhesive 17 that joins the first fibrous sheet 2 and the fiber sheet 4 via the elastic member 5 is 3 to 8 g / m ² . Further, the coating amount of the adhesive 7 for joining the second fibrous sheet 3 and the fiber sheet 4 is 0.8 to 2.2 g / m ² . The application amount of the adhesive 17 is 1.36 to 10 times larger than the application amount of the adhesive 7. The application amount of the adhesive 17 is preferably set to 2 to 5 times the application amount of the adhesive 7.
Thus, in 2nd Embodiment, the application quantity of the adhesive agent 17 which joins the 1st fibrous sheet 2 and the fiber sheet 4 is the adhesive agent which joins the 2nd fibrous sheet 3 and the fiber sheet 4. More than the coating amount of 7.

As a form which apply | coats the adhesives 7 and 17 partially (intermittently), a linear form, a dot form, a stripe form, a spiral form, a block form, a pattern form etc. are mentioned, for example. One of these forms may be used, or a plurality may be combined.
In addition to the hot melt adhesive, various adhesives such as a pressure sensitive adhesive and a curable adhesive can be used as the adhesives 7 and 17. In addition, joining of the 1st fibrous sheet 2 and the fiber sheet 4 is not limited to adhesion | attachment, Various joining methods, such as ultrasonic joining and heat sealing | fusion, can be applied.

As shown in FIGS. 4, 5, and 6, 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 in order to form the collar portion 6 composed of the convex portion 6a and the concave portion 6b. As the elastic member 5, a linear elastic body 5a having stretchability is used. In the second embodiment, polyurethane is used as the linear elastic body 5a.

As shown in FIGS. 3 and 4, the linear elastic body 5 a has a plurality of linear elastic bodies 5 a arranged in the same direction as the longitudinal direction (the x direction in FIGS. 3 and 4) and at a predetermined interval. 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 throughout the region, or may be partially different. In any case, when the fabric 1 is used as the disposable pants 13, the linear elastic body is set so that the elastic force of the body mounting portion 12 (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. As shown in FIGS. 3 and 4, the collar portion 6 is formed with a plurality of rows at predetermined intervals in the x direction. Here, the joint portion of the heel portion 6 with the linear elastic body 5a is referred to as a “heel support point”. In the cloth 1, the number of the linear elastic bodies 5a per unit area can be arbitrarily set. If the number of the linear elastic bodies 5a is increased and the interval between the linear elastic bodies 5a is reduced, the number of the hook support points in the row of the hooks 6 is thereby increased. When the number of the hook support points increases, the convex portions 6a and the concave portions 6b in the row of hook portions 6 can be formed in a uniform shape and the shape can be maintained. Thereby, there is no shape loss of the collar part 6, and the softness | flexibility of the cloth | dough 1, moisture transpiration | evaporation property, heat dissipation, and moisture permeability can be increased. For this purpose, the interval between the flanges 6, that is, the pitch interval between the protrusions 6a is preferably 2 to 7 mm. The pitch interval between the convex portions 6a is more preferably 3.00 to 6.25 mm. When the pitch interval between the convex portions 6a is narrowed, a fine crease is formed and the appearance is beautiful. Further, if the pitch interval between the convex portions 6a is narrowed, the contact area with the skin per heel is reduced, the touch is improved, and the surface area is further increased, so that the absorbability of sweat and the like is improved. On the other hand, if the pitch interval between the convex portions 6a is widened, the elastic force of the polyurethane is moderately suppressed, so that the manufacturing cost can be reduced.

Since the cloth 1 (hereinafter also referred to as “laminated sheet 15”) has a long dimension, the length dimension in the longitudinal direction (x direction in FIGS. 3 and 4) of the laminated sheet 15 is set to a predetermined length. Is cut. 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 that has been in a tensile state is released from the tensile force and contracts due to the restoring force. Due to the shrinkage stress at this time, the fabric 1 (laminated sheet 15) composed of the first fibrous sheet 2, the fiber sheet 4, and the like receives a force in a direction in which the length decreases. Therefore, an uneven surface is formed on the fabric 1 (laminated sheet 15), whereby the heel part 6 is formed. In this way, the dough 1 having a large number of collars 6 can be 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.

The cut fabric 1 is in a contracted state due to the restoring force of the elastic member 5, that is, in a non-tensed state. In this non-tensed state, a large number of ridges 6 extending in the direction (y direction) orthogonal to the longitudinal direction (x direction) of the elastic member 5 are formed, and the rows of the ridges 6 are patterned in the laminated sheet 15.
The laminated sheet 15 is given elasticity by the elastic member 5 disposed inside. Therefore, when the fabric 1 constituted by the laminated sheet 15 is pulled by hand in the x direction in FIGS. 3 and 4, the elastic member 5 extends, so that the fabric 1 expands and spreads. Further, when the hand is released from this state, the elastic member 5 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 disposable pants 13, the cloth 1 has an excellent fit to the body.
Further, the size of the fabric 1 is determined as the disposable pants 13 by the size contracted by the restoring force of the elastic member 5. Therefore, the disposable pants 13 have a large surface area in the extended state. When the wearer wears the disposable pants 13, the stretched body has a large surface area. Therefore, even when excrement, body fluid, etc. leak from the absorbent body 14 (see FIG. 12), excrement, body fluid, etc. can be absorbed by the fabric 1. . Therefore, the disposable pants 13 can prevent the outer (trousers, pants) from being soiled by excrement, body fluid, etc. leaked from the absorber 14.

FIG. 8 is a schematic diagram showing a production line 200 for the dough 1. FIG. 9 is a flowchart showing a method for manufacturing the dough 1. In addition, manufacture of the fabric 1 is executed under the control of a control device (not shown) provided with a CPU in a factory that has been FAized. Hereinafter, the manufacturing method of the fabric 1 will be described with reference to FIGS. 8 and 9. However, the layout of the production line 200 shown in FIG. 8 is only an example. In the production line 200, the arrangement of various devices can be appropriately changed depending on the space of the factory.

(Step S1: Joining of the second fibrous sheet 3 and the fiber sheet 4)
The fiber sheet 4 wound around the sheet roll 201 is conveyed in the −x direction and embossed by a pair of embossing rolls 202a. The fiber sheet 4 is mechanically softened by embossing. In addition, since the some embossing roll 202 is used in the production line 200, it adds and demonstrates an alphabet. However, in each part of the production line 200, an embossing roll 202 having the same embossing pattern, size, and material may be used, or an embossing roll 202 having a different embossing pattern, size, and material may be used. In addition, the pattern (refer FIG. 12) is printed beforehand on the fiber sheet 4 wound by the sheet roll. The embossing described above is performed on the fiber sheet 4 on which the pattern is printed. In the second embodiment, a metal (for example, iron-based material, stainless steel) roll is used for the pair of embossing rolls 202a.

Prior to joining with the second fibrous sheet 3, the adhesive 7 is applied to the fiber sheet 4 that has passed through the embossing roll 202 a by the first adhesive application device 203. In the second embodiment, a hot melt adhesive is used as the adhesive 7, but the present invention is not limited to this. Here, the first adhesive application device 203 will be described.
FIG. 10 is a diagram illustrating the first adhesive application device 203. The first adhesive application device 203 includes a plurality of nozzles 204, a storage unit 205, and a controller 206. The plurality of nozzles 204 apply the adhesive 7 to the first surface of the fiber sheet 4. The storage unit 205 includes a heating unit (not shown) that stores the adhesive 7 and heats the adhesive 7 to a recommended temperature. The controller 206 controls the heating temperature of the heating unit (accommodating unit 205). Moreover, in a part of FIG. 10, a mode that the adhesive agent 7 was apply | coated to the fiber sheet 4 is shown typically with stripe shape.

Returning again to FIG. The second fibrous sheet 3 wound around the sheet roll 207 is conveyed in the −Z direction by the conveying roll 208a and joined to the fiber sheet 4 by the pressing roll 209a. In the second embodiment, the application amount of the adhesive 7 is 1.0 to 2.2 g / m ² , preferably 1.0 to 1.5 g / m ² as described above, and the adhesion area is 15 to It is about 45%. In addition, since a plurality of transport rolls 208 are used in the production line 200, an explanation will be given by adding alphabets. However, in each part of the production line 200, conveyance rolls having the same size and rotation speed may be used, or conveyance rolls having different sizes and rotation speeds may be used. Further, since a plurality of pressing rolls 209 are used in the production line 200, an explanation will be given by adding alphabets. However, in each part of the production line 200, the pressing roll 209 having the same size or the like may be used, or the pressing roll having a different size or the like may be used. The number, size, pressing force, and the like of the pressing roll 209 can be set as appropriate.

(Step S2: Application of functional substance)
After the second fibrous sheet 3 and the fiber sheet 4 are joined, a functional substance is applied to the fiber sheet 4. In the second embodiment, the functional substance is different from a hot melt adhesive or the like, and includes the deodorant, insect repellent, fragrance, waterproofing agent, antifouling agent, antibacterial agent and the like described in the above embodiment. is there. Although 2nd Embodiment demonstrates the case where a softening agent is apply | coated in addition to a deodorizer and a fragrance | flavor, it is not limited to this.

The functional substance application device 150 has a nozzle (not shown) and has functionality on the second surface of the fiber sheet 4 (the surface on which the second fibrous sheet 3 is not bonded and the adhesive 7 is not applied). A device for applying a substance. In order to simplify the illustration, only one functional substance applying device 150 is shown in FIG. 8, but a plurality of functional substance applying devices 150 may be provided according to the number of functional substances. . If there is no chemical problem, a plurality of functional substances may be mixed and the functional substance may be applied to the fiber sheet 4 by the functional substance applicator 150.

As the deodorant, those described in the above embodiment can be used, but in the second embodiment, alum (potassium alum) or polyphenol is applied by the functional substance applying device 150. In addition, since the liquid which melt | dissolved the metal may be used for functional substances, such as alum, it is preferable to apply | coat to the part (for example, sheet | seats other than the skin surface) which does not touch skin directly. Since the fiber sheet 4 of 2nd Embodiment does not become a skin surface, a metal substance does not touch a wearer. In addition, what is necessary is just to apply | coat the substance described in the above-mentioned embodiment with the functional substance application | coating apparatus 150 as a fragrance | flavor. In addition, what is necessary is just to use a fragrance | flavor properly according to sex, an adult, a child, an area, etc.

The softening agent applied by the functional material applying device 150 softens the fiber sheet 4. As the softening agent, polyol (eg, glycerin) which is a polyhydric alcohol can be used. In 2nd Embodiment, although the example which apply | coats a functional substance after the 2nd fibrous sheet 3 and the fiber sheet 4 were joined was demonstrated, if it is after passing the embossing roll 202a, a functional substance will be used. It may be applied. If a functional substance (for example, glycerin) is applied before passing through the embossing roll 202a, the fiber sheet 4 is easily cut. If the fiber sheet 4 is easily cut, the cut end of the fiber sheet 4 may adhere to the embossing roll 202a, which may hinder the manufacture of the fabric 1.
After the functional substance is applied, the joined second fibrous sheet 3 and fiber sheet 4 are conveyed in the + Z direction by the conveying roll 208b.

(Step S3: Application of the adhesive 17 to the elastic member 5)
The adhesive 17 is applied to the elastic member 5 wound around the elastic roll 210 by the second adhesive application device 211. In the second embodiment, a hot melt adhesive is used as the adhesive 17, but the present invention is not limited to this. The hot melt adhesive of the adhesive 17 and the hot melt adhesive of the adhesive 7 may be the same or different (for example, different in viscosity). Here, the second adhesive application device 211 will be described.
FIG. 11 is a diagram illustrating the second adhesive application device 211. The second adhesive application device 211 includes an application unit 212, a storage unit 213, and a controller 214. The application unit 212 is a device that applies the adhesive 17 to the peripheral surfaces of the plurality of elastic members 5 and has a plurality of comb teeth. The accommodating part 213 accommodates the adhesive agent 17 and has a heating part (not shown) for heating the adhesive agent 17 to a recommended temperature. The controller 214 controls the heating temperature of the heating unit (accommodating unit 213). In addition, in FIG. 11, in order to simplify the figure, dozens of elastic members 5 to which the hot melt adhesive is applied are shown. However, as described above, the elastic members 5 are actually supplied at intervals of 5 to 10 mm. When the elastic member 5 passes between the combs, a hot melt adhesive is applied to the peripheral surface thereof.

(Step S4: Production of laminated sheet 15)
Returning again to FIG. The first fibrous sheet 2 wound around the sheet roll 207 is conveyed in the −Z direction by the conveyance roll 208c. On the other hand, the joined second fibrous sheet 3 and fiber sheet 4 are conveyed in the + Z direction by the conveying roll 208b. The pressing roll 209b presses and joins the first fibrous sheet 1, the joined second fibrous sheet 3 and the fibrous sheet 4 via the elastic member 5 to which the adhesive 17 is applied. Thereby, the lamination sheet 15 is manufactured. The laminated sheet 15 is laminated | stacked in order of the 1st fibrous sheet 2, the elastic member 5, the fiber sheet 4, and the 2nd fibrous sheet 3 from the top (refer FIG. 7).

In FIG. 11, the elastic member 5 is illustrated in a large size for easy understanding, but the diameter of the elastic member 5 is actually about 0.2 to 1.0 mm. Therefore, the adhesion area between the first fibrous sheet 2 and the fiber sheet 4 via the elastic member 5 is about 4 to 20%. In the second embodiment, the adhesion area between the first fibrous sheet 2 and the fiber sheet 4 is smaller than the adhesion area (15 to 45%) between the second fibrous sheet 3 and the fiber sheet 4. When the adhesion area between the first fibrous sheet 2 and the fiber sheet 4 is 15 to 20%, the adhesion area between the second fibrous sheet 3 and the fiber sheet 4 may be 20% or more. As described above, the amount of the hot melt adhesive is such that the adhesive 17 that bonds the first fibrous sheet 2 and the fiber sheet 4 has the second fibrous sheet 3 and the fiber sheet 4 bonded together. More than the adhesive 7 to be bonded.
The laminated sheet 15 obtained by the pressing roll 209b is subjected to a mechanical softening process by embossing with a pair of embossing rolls 202b. Note that the pair of embossing rolls 202b may be provided after the heating device 215, or may be provided before and after the heating device 215. Further, the pair of embossing rolls 202b may be omitted.

(Step S5: Heat treatment)
As described above, elasticity is imparted to the laminated sheet 15 by the elastic member 5 disposed inside the laminated sheet 15. By selecting the elastic force of the elastic member 5, the surface area can be increased from 1.5 times to 5 times. For example, when the dimension required in the x direction is 800 mm in the non-tensioned state of the fabric 1, it is 1200 mm to 4000 mm in the extended state.

If 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 1 needs to be 2400 mm multiplied by the reciprocal of the shrinkage rate of the elastic member 5. However, after joining the first fibrous sheet 2, the second fibrous sheet 3, and the fiber sheet 4 via the elastic member 5, it is cut or released from the extended state by reducing the conveying speed of the conveying roll. In some cases, the shrinkage rate may be ½. Factors that cause the shrinkage rate to decrease include, for example, problems of temperature and humidity in the manufacturing plant, particularly when the temperature is low without temperature control, and the elastic member 5 alone (for example, residual strain of the elastic member 5), the elastic member 5 Examples thereof include a decrease in shrinkage of the elastic member 5 due to the curing of the adhesive 17 applied to the fiber, and the rigidity of the fiber sheet 4. Moreover, the application conditions (application temperature, application amount, viscosity, etc.) of the adhesive 17 may also be affected. Similarly, the application conditions (application temperature, application amount, viscosity, etc.) of the adhesive 7 may also be affected.

Therefore, in the second embodiment, the shrinkage rate of the elastic member 5 is increased by heat-treating the laminated sheet 15 to remove the residual strain of the elastic member 5. In the heat treatment step, the laminated sheet 15 is conveyed in an extended state (a state where the laminated sheet 15 is extended to some extent).
As shown in FIG. 8, in the production line 200, non-contact heating by the heating device 215 and contact heating by the heating roll 216 are performed as the heat treatment. However, either one may be omitted.
The heating device 215 is a non-contact heating device that supplies hot air of 30 to 80 ° C., for example. The plurality of heating rolls 216 are heated to 30 to 80 ° C., for example.
