　以下、本発明の実施形態について、図面を用いて詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
　（実施形態１）
　本発明の実施形態１に係る下半身用使い捨て衣類として使い捨てパンツ１００を例に説明する。 (Embodiment 1)
A disposable pants 100 will be described as an example of the lower-body disposable garment according to the first embodiment of the present invention.
　図１は、本発明の実施形態１に係る使い捨てパンツ１００の正面図であり、図２は、図１に示す使い捨てパンツ１００の展開図である。以下、これらの図を参照して使い捨てパンツ１００について説明する。 FIG. 1 is a front view of a disposable pants 100 according to Embodiment 1 of the present invention, and FIG. 2 is a developed view of the disposable pants 100 shown in FIG. The disposable pants 100 will be described below with reference to these figures.
　使い捨てパンツ１００は、前身頃１１０、後身頃１２０、股下部１３０の各生地片から主に構成される。使い捨てパンツ１００を構成する生地１の詳細については後述するが、生地１は、単一方向に伸縮性を有し、複数のシートが積層された積層シートである。 The disposable pants 100 are mainly composed of pieces of cloth of a front body 110, a back body 120, and a crotch portion 130. Although the details of the cloth 1 constituting the disposable pants 100 will be described later, the cloth 1 is a laminated sheet which has stretchability in a single direction and in which a plurality of sheets are laminated.
　前身頃１１０は、例えば矩形状の生地１よりなり、矩形状の生地の１つの長辺を所定の長さ分内側に折り返して形成されたウェスト部１１５を有する。前身頃１１０においては、生地１が着用時に横方向（着用者の胴回り方向）に伸張するように用いられている。 The front body 110 is made of, for example, a rectangular cloth 1 and has a waist portion 115 formed by folding back one long side of the rectangular cloth by a predetermined length. In the front body 110, the fabric 1 is used so as to extend in the lateral direction (the waistline direction of the wearer) when worn.
　また、後身頃１２０は、前身頃１１０と同様、例えば矩形状の生地１よりなり、矩形状の生地の１つの長辺を所定の長さ分内側に折り返して形成されたウェスト部１２５を有する。後身頃１２０においては、生地１が着用時に横方向（着用者の胴回り方向）に伸張するように用いられている。 Further, the back body 120 is made of, for example, a rectangular cloth 1 like the front body 110, and has a waist portion 125 formed by folding back one long side of the rectangular cloth by a predetermined length. In the back body 120, the fabric 1 is used so as to stretch in the lateral direction (the waistline direction of the wearer) when worn.
　前身頃１１０の一方の短辺と後身頃１２０の一方の短辺とが接合され、前身頃１１０の他方の短辺と後身頃１２０の他方の短辺とが互いに接合されて筒状をなす。すなわち、前身頃１１０と後身頃１２０とを重ねたとき、向かい合う短辺同士が接合される。 One short side of front body 110 and one short side of back body 120 are joined, and the other short side of front body 110 and the other short side of back body 120 are joined to each other to form a tubular shape. That is, when the front body 110 and the back body 120 are stacked, the facing short sides are joined.
　股下部１３０は、例えば矩形状の生地１よりなる。股下部１３０においては、生地１が、着用時に主に前後方向及び又は上下方向に伸張するように用いられている。股下部１３０は、一方の短辺が前身頃１１０のウェスト部１１５を形成する折り返し部分に挟まれた状態で前身頃１１０に接合され、他方の短辺が後身頃１２０のウェスト部１２５を形成する折り返し部分に挟まれた状態で後身頃１２０に接合される。また、股下部１３０と、前身頃１１０及び後身頃１２０とが接合されることにより、股下部１３０と前身頃１１０及び後身頃１２０との間に着用者の脚部を挿通可能な脚部開口部が形成される。また、股下部１３０は、前身頃１１０の脚部開口部側において横方向（幅方向）中央の一部を含む領域と接合され、接合線１３３が形成される。また、股下部１３０は、後身頃１２０の脚部開口部側において横方向（幅方向）中央の一部を含む領域と接合され、接合線１３６が形成される。これにより、前身頃１１０及び後身頃１２０と、股下部１３０とが互いの伸縮性を阻害しあうことを低減できる。このため、股下部１３０を横方向（幅方向）に大きくしても、前身頃１１０及び後身頃１２０が大きく伸張するので、着用時に脚部開口部を大きく確保することができる。 The crotch portion 130 is made of, for example, a rectangular cloth 1. In the crotch portion 130, the fabric 1 is used so as to extend mainly in the front-rear direction and / or the up-down direction when worn. The crotch portion 130 is joined to the front body 110 in a state in which one short side is sandwiched between the folded portions forming the waist portion 115 of the front body 110, and the other short side forms the waist portion 125 of the back body 120. It is joined to the back body 120 in a state of being sandwiched between the folded portions. Also, the leg opening can be inserted between the crotch 130 and the front body 110 and the rear body 120 by joining the crotch 130 with the front body 110 and the rear body 120. Is formed. In addition, the crotch portion 130 is joined to a region including a central portion in the lateral direction (width direction) on the leg opening side of the front body 110, and a joint line 133 is formed. Further, the crotch portion 130 is joined to a region including a central portion in the lateral direction (width direction) on the leg opening side of the back body 120, and a joint line 136 is formed. As a result, it is possible to reduce that the front body 110 and the back body 120, and the crotch portion 130 interfere with each other's stretchability. For this reason, even if the crotch portion 130 is enlarged in the lateral direction (width direction), the front body 110 and the rear body 120 are greatly stretched, so that the leg opening can be largely secured when worn.
　本実施形態では、上記構成により、股下部１３０の短辺がウェスト部と接合されるため、股下部１３０の短辺を脚部開口部側の長辺と接合する場合に比べ、股下部１３０を長く確保することができ、股下部１３０の伸縮性を大きくすることができる。これにより、脚部開口部を大きく開口させることができ、着用者の足の出し入れを容易とすることができる。 In this embodiment, since the short side of the crotch portion 130 is joined to the waist portion by the above configuration, the crotch portion 130 is compared to the case where the short side of the crotch portion 130 is joined to the long side on the leg opening side. A long length can be secured, and the stretchability of the crotch portion 130 can be increased. Thus, the leg openings can be widely opened, and the wearer's feet can be easily put in and out.
　また、本実施形態では、図３、図４に示すように、着用者が着用した状態で、使い捨てパンツ１００の外観をボクサータイプの外観とすることができる。これにより、意匠性を向上させることができる。 Moreover, in this embodiment, as shown to FIG. 3, FIG. 4, the appearance of the disposable pants 100 can be made into the appearance of a boxer type in the state which the wearer wore. Thereby, the designability can be improved.
　なお、使い捨てパンツ１００は、年齢、性別、体形を問わずに使用することができ（子供用、大人用、男性用、女性用など）、また、人以外の動物にも適用することができる。例えば、子供用のパンツは、使用する生地の量が少なく伸縮性に限度があるが、使い捨てパンツ１００を上記構成とすることにより、十分な伸縮性を確保することができる。 The disposable pants 100 can be used regardless of age, gender, or body shape (for children, adults, men, women, etc.), and can also be applied to animals other than humans. For example, although children's pants have a small amount of fabric used and have limited stretchability, sufficient stretchability can be secured by using the disposable pants 100 as described above.
（生地１）
　図５は、実施形態１に係る使い捨てパンツ１００に利用可能な生地１を示す概略平面図である。図５において、生地１は、その生地１の面に沿った長手方向に連続するものである。図５の例では、生地１の長手方向は、Ｘ方向である。生地１は、積層シート３０（図８、図９参照）から形成されている。積層シート３０は、原材シートと、原材シートに設けられた弾性部材５からなる弾性構造体とからなる。生地１においては、その内部に弾性部材５が設けられる。図５に例示された生地１においては、弾性部材５は、複数の弾性体を含み、複数の弾性体は、生地１の長手方向を横切る方向に互いに間隔をあけて設けられている。また、それぞれの弾性部材５の伸びる方向は、生地の長手方向に一致している。生地１においては、多数の弾性部材５の復元力により、図５に示すように生地１の長手方向に沿って凹部と凸部が交互に形成され、凹凸面が形成されている。また、生地１の長手方向に沿って交互に形成された凹部と凸部とからなる凹凸列は、生地１の長手方向を交差する方向（図５の例では、Ｙ方向）に複数列ならんで形成されており、これら複数の凹凸列で襞部が形成されている。また、隣り合う凹凸列の少なくとも一部は、互いに隙間をあけて形成されており、その隙間の形成位置は、弾性部材５の敷設位置に対応する位置となっている。 (Dough 1)
FIG. 5 is a schematic plan view showing the cloth 1 that can be used for the disposable pants 100 according to the first embodiment. In FIG. 5, the dough 1 is continuous in the longitudinal direction along the surface of the dough 1. In the example of FIG. 5, the longitudinal direction of the dough 1 is the X direction. The dough 1 is formed of a laminated sheet 30 (see FIGS. 8 and 9). The laminated sheet 30 is composed of a raw material sheet and an elastic structure made of an elastic member 5 provided on the raw material sheet. In the fabric 1, the elastic member 5 is provided inside thereof. In the fabric 1 illustrated in FIG. 5, the elastic member 5 includes a plurality of elastic bodies, and the plurality of elastic bodies are provided spaced apart from each other in the direction transverse to the longitudinal direction of the fabric 1.

（積層シート３０を形成する原材シートの層数及び層構成）
　図８、図９に示す例では、積層シート３０を形成する原材シートは、少なくとも一部を第１繊維シート２、第２繊維シート３、及び第３繊維シート４の３層の積層構造とするものであるが、原材シートをなす３層の層構成が、第２繊維シートを第３繊維シートに置き換えた層構成とされてよい。原材シートは、第２繊維シートを取り除いた２層の積層構造とされてもよく、また、第３繊維シートを取り除いた第１繊維シートと第２繊維シートの２層の積層構造とされてもよい。 (Number of Layers and Layer Configuration of Raw Material Sheet Forming Laminated Sheet 30)
In the example shown in FIGS. 8 and 9, the raw material sheet forming the laminated sheet 30 has a laminated structure of at least a part of the three layers of the first fiber sheet 2, the second fiber sheet 3 and the third fiber sheet 4 However, the layer structure of the three layers forming the base material sheet may be a layer structure in which the second fiber sheet is replaced with the third fiber sheet. The raw material sheet may have a laminated structure of two layers from which the second fiber sheet is removed, and may also have a laminated structure of two layers of a first fiber sheet from which the third fiber sheet is removed and a second fiber sheet It is also good.
　生地１を、使い捨てパンツ１００を形成するための材料として使用する場合、原材シートにおいて、体液（尿、汗、血液、リンパ液等）についての液拡散性を有する点で、第３繊維シート４としてセルロース系の成分を含有するシート、例えば、紙（ティッシュペーパー、クレープ紙等）又はエアレイド不織布等を用いることが好ましい。また、第１繊維シート２、第２繊維シート３は、それぞれ身体から発せられる汗などの成分や体液との関係において通気性を有する点で、親水性の不織布を用いることが好ましい。具体的には、第３繊維シート４として紙が用いられ、第１繊維シート２、第２繊維シート３としてそれぞれサーマルボンド不織布、スパンレース不織布、スパンボンド不織布等のうちいずれかの不織布が用いられることが好ましい。なお、通気性の観点からは、第１繊維シート２、第２繊維シート３として紙を用いることもできるが、第１繊維シート２、第２繊維シート３のいずれかが不織布とされていることが好ましい。一方で、生地１において、第１繊維シート２、第２繊維シート３、第３繊維シート４のいずれも紙とした場合、生地１が体液を吸収すると生地１に崩壊箇所が生じてしまう虞がある。 When the dough 1 is used as a material for forming the disposable pants 100, it is used as the third fiber sheet 4 in that the raw material sheet has a liquid diffusibility for body fluid (urine, sweat, blood, lymph, etc.) It is preferable to use a sheet containing a cellulose-based component, for example, paper (tissue paper, crepe paper, etc.) or air-laid non-woven fabric, etc. Moreover, it is preferable to use a hydrophilic non-woven fabric as the first fiber sheet 2 and the second fiber sheet 3 in that they have air permeability in relation to components such as sweat emitted from the body and body fluids. Specifically, paper is used as the third fiber sheet 4, and any one of thermal bond nonwoven fabric, spun lace nonwoven fabric, spun bond nonwoven fabric, etc. is used as the first fiber sheet 2 and the second fiber sheet 3. Is preferred. Although paper can be used as the first fiber sheet 2 and the second fiber sheet 3 from the viewpoint of air permeability, either the first fiber sheet 2 or the second fiber sheet 3 is made of a non-woven fabric. Is preferred. On the other hand, when the first fiber sheet 2, the second fiber sheet 3, and the third fiber sheet 4 are all paper in the fabric 1, there is a possibility that the material 1 may absorb the body fluid to cause the fabric 1 to collapse. is there.
（積層シート３０を形成する原材シートの接合）
　図８、図９の例において、原材シートを形成する第１繊維シート２と第３繊維シート４は、弾性部材５を介して部分的に接合されている。 (Joining of Raw Material Sheets Forming Laminated Sheet 30)
In the example of FIG. 8 and FIG. 9, the first fiber sheet 2 and the third fiber sheet 4 that form the raw material sheet are partially joined via the elastic member 5.
　図８、図９の例において、原材シートを形成する第２繊維シート３と第３繊維シート４は、向かい合う全面領域で接合されていてもよいが、互いに部分的に接合されていることが好ましい。第２繊維シート３と第３繊維シート４が部分的に接合されていることで、第２繊維シート３と第３繊維シート４との間に形成される非接合部分により空間９（図１０参照）を形成することができる。そして、このような空間９が形成されていることで、生地１の水分蒸散性（吸水速乾性）、放熱性および透湿性は、より一層優れたものとなる。 In the example of FIG. 8, FIG. 9, although the 2nd fiber sheet 3 and the 3rd fiber sheet 4 which form a raw material sheet may be joined by the facing whole area | region area, it is mutually joined partially. preferable. Since the second fiber sheet 3 and the third fiber sheet 4 are partially joined, a space 9 is formed by the non-joining portion formed between the second fiber sheet 3 and the third fiber sheet 4 (see FIG. 10). Can be formed. And, by forming such a space 9, the water transpiration property (water absorption fast drying property), the heat dissipation property and the moisture permeability of the dough 1 become even more excellent.
　図１１は、生地の他の一例を模式的に示す概略断面図であり、図７のＢ－Ｂ線断面図に対応する断面図である。図８、図９の例において、原材シートを形成する第１繊維シート２と第３繊維シート４は、図１１の例に示すように、互いに部分的に接合されているのが好ましい。これにより、第１繊維シート２と第３繊維シート４との間に非接合部分、即ち、空間４０を形成することができる。そして、このような空間４０が形成されていることで、空間９が形成されている場合と同様に、生地１の水分蒸散性、放熱性および透湿性は、より一層優れたものとなる。 FIG. 11 is a schematic cross-sectional view schematically showing another example of the fabric, and is a cross-sectional view corresponding to the cross-sectional view taken along the line BB in FIG. In the example of FIG. 8 and FIG. 9, it is preferable that the first fiber sheet 2 and the third fiber sheet 4 which form the raw material sheet are partially joined to each other as shown in the example of FIG. Thereby, the non-joining part, ie, the space 40, can be formed between the first fiber sheet 2 and the third fiber sheet 4. And, as in the case where the space 9 is formed, the moisture transpiration property, the heat dissipation property and the moisture permeability of the dough 1 become even more excellent because such a space 40 is formed.
（積層シート３０を形成する原材シートに対する弾性部材５の接合）
　例えば、第２繊維シート３と第３繊維シート４とを接合した部分と接合しない部分とが形成されるように部分的に接合一体化した後に、第２繊維シート３と第３繊維シート４の積層体に対して弾性部材５を介在させつつ、第１繊維シート２を接合する。このように接合することで、第１繊維シート２と第３繊維シート４と第２繊維シート３の積層一体化構造を有する原材シートが形成された状態となり、且つ、第１繊維シート２と第３繊維シート４の間に弾性部材５を介在させて部分的に接合されることで原材シートに弾性部材５が接合された状態となり、積層シート３０が形成される。 (Joining of the elastic member 5 to the raw material sheet forming the laminated sheet 30)
For example, after partially joining and integrating the second fiber sheet 3 and the third fiber sheet 4 so as to form a portion where the second fiber sheet 3 and the third fiber sheet 4 are joined and a portion not joined, the second fiber sheet 3 and the third fiber sheet 4 The first fiber sheet 2 is joined while interposing the elastic member 5 in the laminate. By joining in this manner, a raw material sheet having a laminated and integrated structure of the first fiber sheet 2, the third fiber sheet 4, and the second fiber sheet 3 is formed, and the first fiber sheet 2 and The elastic members 5 are interposed between the third fiber sheets 4 to be partially joined, whereby the elastic members 5 are joined to the raw material sheet, and the laminated sheet 30 is formed.
（原材シートを形成する第１繊維シート２と第３繊維シート４の接合方法）
　原材シートを形成する第１繊維シート２と第３繊維シート４との接合方法及び原材シートに対する弾性部材５の接合方法として、接着を採用した場合、接着剤としてホットメルト接着剤を用いることが好ましい。以下、接着剤としてホットメルト接着剤を用いる場合について説明する。 (The joining method of the 1st fiber sheet 2 and the 3rd fiber sheet 4 which forms a raw material sheet)
When bonding is adopted as a method of joining the first fiber sheet 2 and the third fiber sheet 4 to form the raw material sheet and as a method of joining the elastic member 5 to the raw material sheet, a hot melt adhesive is used as an adhesive. Is preferred. Hereinafter, the case where a hot melt adhesive is used as the adhesive will be described.
　ホットメルト接着剤を用いて、第２繊維シート３と第３繊維シート４とを部分的に接合するには、図９、図１０に示すように、第３繊維シート４にホットメルト接着剤を部分的に塗布し（或いは、第２繊維シート３にホットメルト接着剤を部分的に塗布してもよい）、両者を積層して接合一体化する。このとき、第２繊維シート３と第３繊維シート４との間に接着層７が存在しない非接着部８が形成され、この非接着部８により空間９が形成される。 In order to partially bond the second fiber sheet 3 and the third fiber sheet 4 using a hot melt adhesive, as shown in FIGS. 9 and 10, the third fiber sheet 4 is provided with a hot melt adhesive. It partially coats (or, the hot melt adhesive may be partially coated on the second fiber sheet 3), and both are laminated and joined together. At this time, a non-adhesive portion 8 in which the adhesive layer 7 does not exist is formed between the second fiber sheet 3 and the third fiber sheet 4, and a space 9 is formed by the non-adhesive portion 8.
　また、第１繊維シート２と第３繊維シート４との間には弾性部材５が介在するため、弾性部材５の箇所で第１繊維シート２と第３繊維シート４とを接合することにより、第１繊維シート２と第３繊維シート４との部分的接合が行われる。すなわち、図９に示すように、所定間隔を置いて平行に多数配列されている弾性部材５の周面にホットメルト接着剤が吹き付けて塗布され、このホットメルト接着剤が塗布された弾性部材５は、第３繊維シート４の面と、第１繊維シート２との間に配置され、これらの間に弾性部材５を挟み込んで積層し、接合一体化される。図１０において特に図示しないが、弾性部材５の存在しない第１繊維シート２と第３繊維シート４との対向面は非接着部８となっており、この非接着部８により空間９が形成されている。このように、非接着部８による空間９が形成されている構造により、生地１における水分蒸散性、放熱性および透湿性の各機能が向上する。 In addition, since the elastic member 5 intervenes between the first fiber sheet 2 and the third fiber sheet 4, by joining the first fiber sheet 2 and the third fiber sheet 4 at the location of the elastic member 5, Partial bonding of the first fiber sheet 2 and the third fiber sheet 4 is performed. That is, as shown in FIG. 9, a hot melt adhesive is sprayed and applied to the peripheral surface of a large number of elastic members 5 arranged in parallel at predetermined intervals, and the elastic member 5 to which the hot melt adhesive is applied. Is disposed between the surface of the third fiber sheet 4 and the first fiber sheet 2, and the elastic member 5 is sandwiched between them, laminated, and integrally joined. Although not particularly shown in FIG. 10, the opposing surface of the first fiber sheet 2 and the third fiber sheet 4 in which 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 ing. As described above, the structure in which the space 9 is formed by the non-adhesive portion 8 improves the functions of the water transpiration, the heat dissipation, and the moisture permeability in the dough 1.
（凹凸列６及び襞部６０）
　図６には、生地１の概略斜視図が示され、図７には、図５に示す生地１の概略拡大図が示されている。また、図８には、図７のＡ－Ａ線断面図が示されている。生地１においては、図６から図８に示すように、複数の凸部６ａと凹部６ｂが形成されており、生地１に凹凸面が形成されている。生地１においては、生地１の長手方向に沿って交互に連続形成された凸部６ａと凹部６ｂとからなる凹凸列６が形成されている。凹凸列６は、生地１の長手方向に複数並んで形成されており、隣り合う凹凸列の少なくとも一部が互いに隙間をあけて形成されている。生地１の平面視上、隙間の形成された部分が弾性部材５の設置位置に対応する。そして、生地１においては、このような複数の凹凸列６が襞部６０を形成している。凹凸列６の長さは、図５および図６におけるＸ方向（第１方向）に沿って一端から他端まで一列に延びていることが、生地１をその長手方向に沿った一方端から他方端まで無駄なく使い捨てパンツ１００として利用可能とすることができる観点からは好適である。 (Uneven rows 6 and ridges 60)
FIG. 6 shows a schematic perspective view of the dough 1 and FIG. 7 shows a schematic enlarged view of the dough 1 shown in FIG. Further, FIG. 8 shows a cross-sectional view taken along the line AA of FIG. In the fabric 1, as shown in FIGS. 6 to 8, a plurality of convex portions 6 a and concave portions 6 b are formed, and an uneven surface is formed on the fabric 1. In the fabric 1, a concavo-convex row 6 including convex portions 6 a and concave portions 6 b continuously and alternately formed along the longitudinal direction of the fabric 1 is formed. A plurality of concavo-convex rows 6 are formed side by side in the longitudinal direction of the fabric 1, and at least a part of the adjacent concavo-convex rows is formed with a gap therebetween. The portion where the gap is formed corresponds to the installation position of the elastic member 5 in a plan view of the fabric 1. And in the cloth 1, such a plurality of concavo-convex lines 6 form a ridge portion 60. The length of the concavo-convex row 6 extends in a line from one end to the other end along the X direction (first direction) in FIGS. 5 and 6, from one end to the other along the longitudinal direction It is suitable from the viewpoint that it can be used as disposable pants 100 without waste to the end.
　生地１においては、襞部６０を形成する凸部６ａと凹部６ｂは、原材シートに接合されている複数の弾性部材５の伸縮力に応じて形状変形可能に形成されている。 In the fabric 1, the convex portion 6 a and the concave portion 6 b forming the collar portion 60 are formed so as to be capable of shape deformation in accordance with the stretching force of the plurality of elastic members 5 joined to the raw material sheet.
（襞部６０の形成パターン）
　生地１においては、襞部６０の形成パターンは、凸部６ａと凹部６ｂの大きさやピッチ、凹凸列６の幅、凸部６ａと凹部６ｂの不均一性などによって定められ、これらは弾性部材５の選択や、弾性部材５の配置条件などの諸条件に応じて定められる。 (Formation pattern of ridges 60)
In the fabric 1, the formation pattern of the ridges 60 is determined by the size and pitch of the convex portions 6 a and the concave portions 6 b, the width of the concavo-convex row 6, the nonuniformity of the convex portions 6 a and the concave portions 6 b, etc. It is determined in accordance with various conditions such as the selection of and the arrangement condition of the elastic member 5.
　例えば、図５や図６に示すように、弾性部材５が線状弾性体５ａである場合を想定すると、図５、図６に示すように、生地１において、線状弾性体５ａはその線状に延びる方向が長手方向（図５、図６においてＸ方向）と同一の方向に配置され、且つ所定間隔を置いて多数の線状弾性体５ａが平行に配置されている。即ち、線状弾性体５ａは、Ｙ方向に間隔を設けて多数配置されており、線状弾性体列が形成されている。なお、線状弾性体５ａをＹ方向に設ける間隔は、ほぼ均等な間隔でもよく、例えば、生地１の周辺部において間隔を短くして線状弾性体５ａを密に配置するようにしてもよい。更に、生地１の中央部から周辺部に向けて間隔を徐々に短くしてもよい。これに代えて、もしくは、これと併用して、生地１の周辺部の線状弾性体５ａの弾性力と、生地１の中央部の線状弾性体５ａの弾性力とを異ならせ、周辺部の線状弾性体５ａの弾性力を中央部の線状弾性体５ａの弾性力より強くするようにしてもよい。なお、本実施形態においては、生地１の周辺部とは、図５のＹ方向の正側の端部から中央に向けて５～３０％程度の範囲、Ｙ方向の負側の端部から中央に向けて５～３０％程度の範囲であり、中央部は周辺部を除く範囲である。 For example, as shown in FIGS. 5 and 6, assuming that the elastic member 5 is a linear elastic body 5a, as shown in FIG. 5 and FIG. The extending direction is arranged in the same direction as the longitudinal direction (the X direction in FIGS. 5 and 6), and a number of linear elastic bodies 5a are arranged in parallel at a predetermined interval. That is, a large number of linear elastic bodies 5a are arranged at intervals in the Y direction, and a linear elastic body row is formed. The intervals at which the linear elastic bodies 5a are provided in the Y direction may be substantially equal intervals. For example, the linear elastic bodies 5a may be densely arranged by shortening the intervals at the peripheral portion of the fabric 1 . Furthermore, the distance may be gradually shortened from the center to the periphery of the dough 1. Alternatively, or in combination with this, the elastic force of the linear elastic body 5a at the peripheral portion of the dough 1 and the elastic force of the linear elastic body 5a at the central portion of the fabric 1 are made different. The elastic force of the linear elastic body 5a may be made stronger than the elastic force of the linear elastic body 5a at the central portion. In the present embodiment, the peripheral portion of the dough 1 is a range of about 5 to 30% from the end on the positive side in the Y direction in FIG. 5 to the center, the end from the negative side on the Y direction The central part is the range excluding the peripheral part.
　図９には、図７のＢ－Ｂ線断面図が示されている。生地１においては、図９に示すように、第１繊維シート２と第３繊維シート４との間に複数の線状弾性体５ａが互いに所定の間隔をあけて設けられており、隣り合う線状弾性体５ａ相互の間隔は適宜設定されてよい。すなわち、単位面積当たりの線状弾性体５ａの本数は任意に設定できる。ただし、線状弾性体５ａの本数を多くして隣り合う線状弾性体５ａ相互の間隔を小さくすれば、一列の凹凸列６における凸部６ａと凹部６ｂを細かに形成することができて、汗の通路となる凹部の数を増大させることができるばかりか、その形状を保持することができる。それによって襞部６０の型崩れがなく、生地１の柔軟性、水分蒸散性、放熱性および透湿性を増大させる観点から好ましいものとなる。このような趣旨から、襞部６０相互の間隔、即ち、凸部６ａ相互間のピッチ間隔は、２．００ｍｍ～７．００ｍｍが好ましい。この凸部６ａ相互間のピッチ間隔は、３．００ｍｍ～６．２５ｍｍがより好ましい。凸部６ａ相互間のピッチ間隔を狭くすることにより、きめの細かな襞ができるので外観が美しくなり、また１つの襞当たりの肌との接触面積は小さくなるので肌触りがよくなり、更に単位体積当たりの表面積が大きくなるので汗などの吸収性が向上する。一方、凸部６ａ相互間のピッチ間隔を広くすることにより、線状弾性体５ａの弾性力を適度に抑えることができ、製造コストを低減することができる。 FIG. 9 shows a cross-sectional view taken along the line BB in FIG. In the fabric 1, as shown in FIG. 9, a plurality of linear elastic bodies 5 a are provided between the first fiber sheet 2 and the third fiber sheet 4 at predetermined intervals, and adjacent lines are adjacent to each other. The distance between the elastic bodies 5a may be set appropriately. That is, the number of linear elastic bodies 5a per unit area can be set arbitrarily. However, if the number of linear elastic bodies 5a is increased to reduce the distance between adjacent linear elastic bodies 5a, the convex portions 6a and the concave portions 6b in a row of concavo-convex rows 6 can be formed finely, Not only can the number of recesses that provide the passage for sweat be increased, but the shape can be maintained. As a result, there is no loss of shape of the collar portion 60, which is preferable from the viewpoint of increasing the softness, moisture transpiration, heat dissipation and moisture permeability of the dough 1. From such a point of view, the distance between the ridges 60, ie, the pitch distance between the projections 6a, is preferably 2.00 mm to 7.00 mm. The pitch distance 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 becomes beautiful, and the contact area with one skin per contact becomes small, so that the touch becomes good, and unit volume Since the surface area of the hit increases, the absorbability of sweat etc. is improved. On the other hand, the elastic force of the linear elastic body 5a can be appropriately suppressed by widening the pitch interval between the convex portions 6a, and the manufacturing cost can be reduced.
　なお、図５、図６では隣り合う凹凸列６を形成する凸部６ａと凹部６ｂについて、それぞれの凹凸列６を形成する凸部６ａと凹部６ｂがＹ方向に連続的につながった状態で形成されるように図示されているが、線状弾性体５ａの本数や配置の仕方などにより、凸部６ａと凹部６ｂが不連続になる部分を生じてもよい。また、隣り合う凹凸列を形成する凸部６ａと凹部６ｂの形成位置が互いにＸ方向にずれた状態で凹凸列６が形成されてもよい。このような場合、襞部６０は、隣り合う凹凸列６を形成する凸部６ａと凹部６ｂがＹ方向に不連続となるような部分を有することとなる。すなわち、襞部６０は、不均一に凸部６ａと凹部６ｂを形成したパターンにて形成される。 In FIG. 5 and FIG. 6, the convex portion 6a and the concave portion 6b forming the concavo-convex row 6 adjacent to each other are formed such that the convex portion 6a and the concave portion 6b forming the respective concavo-convex row 6 are continuously connected in the Y direction. Although it is illustrated so that it may be illustrated, depending on the number of linear elastic bodies 5a, the arrangement method, etc., a portion where the convex portion 6a and the concave portion 6b become discontinuous may be generated. Further, the concavo-convex array 6 may be formed in a state in which the formation positions of the convex portions 6 a and the concave portions 6 b forming the concavo-convex rows adjacent to each other are shifted in the X direction. In such a case, the ridge portion 60 has a portion in which the convex portion 6a and the concave portion 6b forming the adjacent concavo-convex row 6 are discontinuous in the Y direction. That is, the ridge portion 60 is formed in a pattern in which the convex portion 6 a and the concave portion 6 b are formed unevenly.
（生地１の製造方法）
　次に、生地１を製造する方法について一例を挙げて説明する。ここでは、生地１が第１繊維シート２、第３繊維シート４、第２繊維シート３の積層構造を有する原材シートを用い、弾性部材５として線状弾性体５ａを用い、線状弾性体５ａとして糸状ゴムを用い、また弾性部材５と原材シートとの接合に接着剤、具体的にはホットメルト接着剤を用いる場合を例にとり、生地１の製造方法について説明する。 (Method of manufacturing dough 1)
Next, a method of producing the dough 1 will be described by way of an example. Here, using the raw material sheet having the laminated structure of the first fiber sheet 2, the third fiber sheet 4 and the second fiber sheet 3, using the linear elastic body 5 a as the elastic member 5, a linear elastic body A method of manufacturing the fabric 1 will be described by taking a case where thread rubber is used as 5a and an adhesive, specifically a hot melt adhesive, is used for bonding the elastic member 5 and the base sheet.
　また、生地１においては、第３繊維シート４としてセルロース系の成分を含有するシートを用いることが好ましい点、および第１繊維シート２、第２繊維シート３としてそれぞれ不織布を用いることが好ましい点を考慮して、第３繊維シート４として紙を用い、第１繊維シート２、第２繊維シート３としてそれぞれ不織布（例えば、サーマルボンド不織布、スパンレース不織布、スパンボンド不織布等）を用いる場合を例に挙げて説明する。 Further, in the fabric 1, it is preferable to use a sheet containing a cellulose-based component as the third fiber sheet 4 and to use non-woven fabrics as the first fiber sheet 2 and the second fiber sheet 3, respectively. Considering the case where paper is used as the third fiber sheet 4 and nonwoven fabrics (for example, thermal bond nonwoven fabric, spunlace nonwoven fabric, spunbond nonwoven fabric etc.) are used as the first fiber sheet 2 and the second fiber sheet 3, respectively. I will list and explain.
　第３繊維シート４の材料となる紙が巻かれたロール（第３繊維シート原反）から、紙である第３繊維シート４が繰り出される。繰り出された第３繊維シート４はエンボスロールに通され、第３繊維シートがロール間で押圧されることにより第３繊維シート４を機械的に柔軟化する処理（機械的柔軟化処理）が行われる。さらに第３繊維シート４にはホットメルト接着剤が塗布される。機械的柔軟化処理は、シート材の状態を機械的な作用によって柔軟な状態とする処理を示す。機械的柔軟化処理は、特に限定されず、例えば、平ロールを用いたエンボス処理や、ロール面に多数の突起を有する噛み合せロールを用いたエンボス処理などが用いられてもよい。機械的柔軟化処理として後者のように噛み合せロールを用いたエンボス処理が用いられた場合、第３繊維シート４に多数の微細な孔を開けることができる。この場合、エンボス処理後の第３繊維シート４にホットメルト接着剤が部分的に吹き付けられた際に、第３繊維シート４に形成された微細な孔にホットメルト接着剤が浸透するようになり、後述の第２繊維シート３との接着しやすさが向上する。また、機械的に柔軟化する処理としてエンボス処理が採用される場合においては、エンボス加工装置を複数設けてエンボス処理が繰り返し行われてもよい。この場合、エンボス加工装置は同じものでもよく、複数種類のエンボス加工装置を設けてもよい。複数種類のエンボス加工装置が設けられる場合、複数種類のエンボス加工装置としては、エンボスを与える方向や、付与されるエンボスの形状およびその大きさを互いに異にする装置が採用されてよい。機械的に柔軟化する処理により、第３繊維シート４の柔軟性が向上し、肌触りを向上させることができる。なお、機械的に柔軟化する処理には、エンボス加工以外の機械加工が採用されてよい。また、機械的柔軟化処理に代えて、又は機械的柔軟化処理に加え、柔軟剤等の薬剤を用いて第３繊維シート４を柔軟化する化学的柔軟化処理を行ってもよい。 The third fiber sheet 4, which is paper, is unrolled from a roll (third fiber sheet raw fabric) on which the paper to be the material of the third fiber sheet 4 is wound. The fed third fiber sheet 4 is passed through an emboss roll, and the third fiber sheet is pressed between the rolls to perform a process (mechanical softening process) for mechanically softening the third fiber sheet 4. It will be. Furthermore, a hot melt adhesive is applied to the third fiber sheet 4. The mechanical softening process indicates a process of making the sheet material flexible by mechanical action. The mechanical softening process is not particularly limited, and, for example, an embossing process using a flat roll, an embossing process using an interlocking roll having a large number of protrusions on the roll surface, and the like may be used. When the embossing using a meshing roll is used as the latter as the mechanical softening treatment, a large number of fine holes can be opened in the third fiber sheet 4. In this case, when the hot melt adhesive is partially sprayed to the third fiber sheet 4 after the embossing process, the hot melt adhesive will penetrate into the fine holes formed in the third fiber sheet 4 The ease of bonding with the second fiber sheet 3 described later is improved. Moreover, when embossing is employ | adopted as a process which softens mechanically, multiple embossing apparatuses may be provided and embossing may be performed repeatedly. In this case, the embossing devices may be the same, or a plurality of embossing devices may be provided. When a plurality of types of embossing devices are provided, as the plurality of types of embossing devices, devices may be employed in which the directions of emboss application, the shapes of the applied emboss shapes, and the sizes thereof are different from each other. The mechanical softening treatment can improve the flexibility of the third fiber sheet 4 and improve the touch. In addition, mechanical processing other than embossing may be employ | adopted as the process softened mechanically. Also, instead of or in addition to the mechanical softening process, a chemical softening process may be performed to soften the third fiber sheet 4 using a drug such as a softener.
　一方、第２繊維シート３の材料となる不織布が巻かれたロール（第２繊維シート原反）から、不織布である第２繊維シート３が繰り出される。この第２繊維シート３は、ホットメルト接着剤が塗布された第３繊維シート４に重ね合わされた状態とされて一対の平ロールに通されることで圧着され、第２繊維シート３と第３繊維シート４の両者を積層した接合シートが製造される。この接合シートにおいて、第２繊維シート３と第３繊維シート４とは部分的に接合される。 On the other hand, the 2nd fiber sheet 3 which is nonwoven fabric is drawn | fed out from the roll (2nd fiber sheet original fabric) by which the nonwoven fabric used as the material of the 2nd fiber sheet 3 was wound. The second fiber sheet 3 is brought into a state of being superimposed on the third fiber sheet 4 to which the hot melt adhesive is applied, and is pressure-bonded by being passed through a pair of flat rolls. A bonding sheet in which both of the fiber sheets 4 are laminated is manufactured. In this joining sheet, the second fiber sheet 3 and the third fiber sheet 4 are partially joined.
　多数の線状弾性体５ａを並列状に巻回してなるロールからは、多数列の線状弾性体５ａが繰り出される。このとき、線状弾性体５ａは所定の引っ張り力で引っ張られた状態（伸長状態）を維持して繰り出される。繰り出された伸長状態の線状弾性体５ａには、接着剤としてホットメルト接着剤が吹き付けられる。線状弾性体５ａには、その長さ方向全長に亘って且つ線状弾性体５ａの全周面に連続的に接着剤が吹き付けられる。 A large number of rows of linear elastic bodies 5a are fed out from a roll formed by winding a large number of linear elastic bodies 5a in parallel. At this time, the linear elastic body 5a is drawn out while maintaining a stretched state (extended state) with a predetermined tensile force. A hot melt adhesive is sprayed as an adhesive on the stretched linear elastic body 5a in the stretched state. An adhesive is continuously sprayed to the linear elastic body 5a over the entire length in the length direction and on the entire peripheral surface of the linear elastic body 5a.
　第１繊維シート２の材料となる不織布が巻かれたロール（第１繊維シート原反）から、不織布である第１繊維シート２が繰り出される。この第１繊維シート２は、上記の接合シートと向い合わせになるように送り出される。接合シートと第１繊維シート２との間には、ホットメルト接着剤が塗布された線状弾性体５ａが挟み込まれるように送り出され、接合シートと第１繊維シート２との間に線状弾性体５ａが供給された構造体が形成される。この場合、線状弾性体５ａは接合シートの第３繊維シート４の面と、第１繊維シート２との間に供給される。 The first fiber sheet 2 which is a non-woven fabric is drawn out from a roll (first fiber sheet raw fabric) on which the non-woven fabric to be the material of the first fiber sheet 2 is wound. The first fiber sheet 2 is fed so as to face the above-mentioned joining sheet. Between the bonding sheet and the first fiber sheet 2, the linear elastic body 5 a to which the hot melt adhesive is applied is sent so as to be sandwiched, and the line elastic between the bonding sheet and the first fiber sheet 2 A structure supplied with the body 5a is formed. In this case, the linear elastic body 5 a is supplied between the surface of the third fiber sheet 4 of the joining sheet and the first fiber sheet 2.
　接合シートの第３繊維シート４の面と第１繊維シート２の面との間に線状弾性体５ａが挟み込まれるように線状弾性体５ａが供給された構造体は、平ロールに通される。このとき、平ロールにより、接合シート、線状弾性体５ａ、第１繊維シート２は互いに圧着されて積層一体化される。ここで、第１繊維シート２と第３繊維シート４とは、線状弾性体５ａを介しての接合であることから、第１繊維シート２と第３繊維シート４とは部分的に接合される。このようにして、第２繊維シート３と第３繊維シート４とが部分的に接合され、且つ、第１繊維シート２と第３繊維シート４とが部分的に接合された積層シートが形成される。積層シートには、必要に応じて機械的柔軟化処理が施されてもよい。機械的柔軟化処理としては、例えば、積層シートをエンボスロールに通す処理が採用されてよい。機械的柔軟化処理が行われることで、積層シートから形成される積層シート３０の柔軟性を向上させることができ、生地１の柔軟性をさらに向上させることができることとなる。 The structure to which the linear elastic body 5a is supplied so that the linear elastic body 5a is sandwiched between the surface of the third fiber sheet 4 of the joining sheet and the surface of the first fiber sheet 2 is passed through a flat roll. Ru. At this time, the joining sheet, the linear elastic body 5a, and the first fiber sheet 2 are pressure-bonded to each other and integrally laminated by the flat roll. Here, since the first fiber sheet 2 and the third fiber sheet 4 are joined via the linear elastic body 5a, the first fiber sheet 2 and the third fiber sheet 4 are partially joined. Ru. In this manner, a laminated sheet in which the second fiber sheet 3 and the third fiber sheet 4 are partially bonded and the first fiber sheet 2 and the third fiber sheet 4 are partially bonded is formed. Ru. The laminated sheet may be subjected to mechanical softening treatment as required. As the mechanical softening treatment, for example, a treatment of passing the laminated sheet through an embossing roll may be employed. By performing the mechanical softening process, the flexibility of the laminated sheet 30 formed from the laminated sheet can be improved, and the flexibility of the fabric 1 can be further improved.
　積層シートは、その長手方向（図５、図６においてＸ方向）における長さ寸法を所定の長さにするための裁断処理を施される。この裁断処理により、次のように第１繊維シート２、第２繊維シート３、第３繊維シート４および線状弾性体５ａを有する生地１が形成される。線状弾性体５ａの切断により、引っ張り状態にあった線状弾性体５ａは、引っ張り力から解放されて線状弾性体５ａの復元力によって、線状弾性体５ａは収縮する。このとき、線状弾性体５ａの復元力の作用に伴う収縮応力が第１繊維シート２、第２繊維シート３、第３繊維シート４に作用する。すなわち、第１繊維シート２と第２繊維シート３と第３繊維シート４は収縮する方向に力を受ける。第１繊維シート２と第２繊維シート３と第３繊維シート４は柔軟に形成されており、線状弾性体５ａの収縮方向に沿って縮む。このとき、特に、第１繊維シート２の表面には凸部６ａと凹部６ｂが形成されて凹凸面が形成される。凸部６ａと凹部６ｂは、線状弾性体５ａの収縮方向に沿って交互に並んで形成されて凹凸列６が形成される。また、線状弾性体５ａの収縮方向を横断する方向に複数の凹凸列６が並んで形成される。こうして、複数の凹凸列６が形成されて襞部６０が形成される。このようにして、襞部６０を有する積層シート３０、即ち、生地１が形成される。 The laminated sheet is subjected to a cutting process for setting the length dimension in the longitudinal direction (the X direction in FIG. 5 and FIG. 6) to a predetermined length. By this cutting process, the fabric 1 having the first fiber sheet 2, the second fiber sheet 3, the third fiber sheet 4 and the linear elastic body 5a is formed as follows. By cutting the linear elastic body 5a, the linear elastic body 5a in a stretched state is released from the tensile force, and the linear elastic body 5a contracts due to the restoring force of the linear elastic body 5a. At this time, contraction stress due to the action of the restoring force of the linear elastic body 5 a acts on the first fiber sheet 2, the second fiber sheet 3, and the third fiber sheet 4. That is, the first fiber sheet 2, the second fiber sheet 3 and the third fiber sheet 4 receive a force in the shrinking direction. The first fiber sheet 2, the second fiber sheet 3 and the third fiber sheet 4 are formed flexibly and contract along the contraction direction of the linear elastic body 5a. At this time, in particular, the convex portion 6 a and the concave portion 6 b are formed on the surface of the first fiber sheet 2 to form an uneven surface. The convex portions 6 a and the concave portions 6 b are alternately formed along the contraction direction of the linear elastic body 5 a to form the concavo-convex row 6. In addition, a plurality of concavo-convex rows 6 are formed side by side in a direction transverse to the contraction direction of the linear elastic body 5a. Thus, the plurality of concavo-convex rows 6 are formed, and the ridge portion 60 is formed. In this manner, the laminated sheet 30 having the ridges 60, ie, the dough 1 is formed.
　図５、図６に例示された生地１において、線状弾性体５ａは復元力により縮んだ状態、即ち、非引っ張り状態にあり、この非引っ張り状態にある線状弾性体５ａの長手方向（図５、図６における積層シート３０の長手方向、即ち、Ｘ方向）と直交する方向（図５、図６における積層シート３０の幅方向、即ち、Ｙ方向）に延びる凸部６ａと凹部６ｂがＸ方向に多数並んで形成されて凹凸列６が形成される。凹凸列６は、Ｙ方向に複数列並んで形成されており、全体として生地１の平面視上、襞部６０が形成されていることとなる。 In the fabric 1 illustrated in FIGS. 5 and 6, the linear elastic body 5a is in a state of being contracted due to 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 5 and 6, the protrusion 6a and the recess 6b extending in the direction orthogonal to the longitudinal direction of the laminated sheet 30, ie, the X direction (the width direction of the laminated sheet 30 in FIG. 5, FIG. 6, ie, the Y direction) A large number of concavo-convex rows 6 are formed side by side in the direction. The uneven row 6 is formed in a plurality of rows in the Y direction, and the ridge portion 60 is formed in a plan view of the dough 1 as a whole.
　積層シート３０の内部に配置された線状弾性体５ａにより、積層シート３０には弾性力が付与されている。従って、積層シート３０である生地１が図５、図６におけるＸ方向に引っ張られると、線状弾性体５ａが伸びることによって生地１も伸びて広がり、またこの状態を解放すると、線状弾性体５ａはその復元力により収縮し、それにより生地１も元の状態に復帰する。このように、生地１は伸縮性を有するので、生地１を使い捨てパンツ１００として使用した場合に身体に対するフィット感に優れたものとなる。 An elastic force is applied to the laminated sheet 30 by the linear elastic body 5 a disposed inside the laminated sheet 30. Therefore, when the cloth 1 as the laminated sheet 30 is pulled in the X direction in FIGS. 5 and 6, the cloth 1 is also expanded by the expansion of the linear elastic body 5a, and when this state is released, the linear elastic body 5a shrinks by its restoring force, thereby returning the dough 1 to its original state. As described above, since the fabric 1 has stretchability, when the fabric 1 is used as the disposable pants 100, the fit to the body is excellent.
　また、生地１が、多数の凹凸列６からなる襞部６０において隣り合う列を形成する凹凸列６が凸部６ａと凹部６ｂの形成位置をＸ方向にずれた位置として形成されたものである場合において、生地１を使い捨てパンツ１００として使用した場合には、使い捨てパンツ１００と地肌との間に汗が生じたとしても、汗が生地１の襞部６０をＸ方向に分岐しながらＹ方向に進行しやすくなることから、拡散性がより向上して、汗が限定的なエリアに滞在しにくくなり、蒸れを生じにくい使い捨てパンツ１００となすことができる。 Further, in the cloth 1 in the ridge portion 60 consisting of a large number of uneven rows 6, the uneven rows 6 forming adjacent rows are formed with the positions where the protrusions 6a and the recesses 6b are formed shifted in the X direction. In the case where the fabric 1 is used as the disposable pants 100, the sweat branches the rib portion 60 of the fabric 1 in the X direction even in the Y direction even if the sweat occurs between the disposable pants 100 and the skin. Since it becomes easy to progress, the diffusivity is further improved, it becomes difficult for sweat to stay in a limited area, and it is possible to make the disposable pants 100 hard to cause stuffiness.
　第１繊維シート２、第２繊維シート３として親水性の不織布を用いる場合には、親水性の繊維として、例えば、水硬性組成物との密着性の点から、ビニルアルコール系繊維および親水化ポリプロピレン系繊維などを用いることができる。なお、第１繊維シート２、第２繊維シート３のそれぞれの目付量は一例として１０～５０ｇ／ｍ２が好ましい。 When a hydrophilic non-woven fabric is used as the first fiber sheet 2 and the second fiber sheet 3, examples of hydrophilic fibers include vinyl alcohol fibers and hydrophilized polypropylene from the viewpoint of adhesion with a hydraulic composition. A system fiber etc. can be used. The coating weight of each of the first fiber sheet 2 and the second fiber sheet 3 is preferably 10 to 50 g / m 2 as an example.
　第３繊維シート４として紙を用いる場合には、パルプを主原料とする材料を用いることができる。原料となるパルプとしては、木材パルプ、合成パルプ、古紙パルプ等を用いることができる。また、パルプなどの天然繊維に限られず、レーヨン等の再生繊維等も用いることができる。なお、第３繊維シート４の目付量は一例として１０～５０ｇ／ｍ２が好ましい。 When using paper as the 3rd fiber sheet 4, the material which uses a pulp as a main raw material can be used. Wood pulp, synthetic pulp, waste paper pulp and the like can be used as the raw material pulp. Moreover, not only natural fibers such as pulp but also regenerated fibers such as rayon can be used. The weight per unit area of the third fiber sheet 4 is preferably 10 to 50 g / m 2 as an example.
　また、生地１が製造される過程で、第３繊維シート４に接着剤が塗布された状態を経ることとなる。第３繊維シート４における接着剤の塗布パターンは、特に限定されず、線状、点状、ストライプ状、スパイラル状、ブロック状、パターン状等に塗布する方法が挙げられる。また、生地１が製造される過程で線状弾性体５ａに接着剤が塗布された状態となる。線状弾性体５ａにおける接着剤の塗布パターンは、特に限定されず、線状、点状、スパイラル状、パターン状等に塗布する方法が挙げられる。塗布パターンとしては、それらのうちの１つが用いられても或いは複数のパターンが組み合わせて用いられてもよい。 Further, in the process of manufacturing the fabric 1, the third fiber sheet 4 is subjected to a state in which the adhesive is applied. The application pattern of the adhesive in the third fiber sheet 4 is not particularly limited, and examples thereof include a linear, dot, stripe, spiral, block, pattern and the like. Further, in the process of manufacturing the fabric 1, the adhesive is applied to the linear elastic body 5 a. The application pattern of the adhesive on the linear elastic body 5a is not particularly limited, and examples thereof include a method of applying in the form of a line, a dot, a spiral, a pattern, and the like. As the application pattern, one of them may be used or a plurality of patterns may be used in combination.

　図１５は、本発明の実施形態３に係る使い捨てパンツ３００の製造工程を表す説明図である。 FIG. 15 is an explanatory view showing a manufacturing process of the disposable pants 300 according to the third embodiment of the present invention.
　使い捨てパンツ３００は、前身頃１１０となる第１長尺体７５及び後身頃１２０となる第２長尺体７６が順次搬送されながら形成される。この時、第１長尺体７５及び第２長尺体７６は、搬送方向（図１５中、Ａ方向）に所定の張力が加えられた状態で流れている。言い換えると、これら第１長尺体７５及び第２長尺体７６は、自然長の長さに比べて、張力が加わった分だけ伸長した状態で搬送方向に流れている。この伸び量は任意に設定することができるが、第１長尺体７５及び第２長尺体７６が適度に伸長した状態（例えば、２０％伸長した状態）で搬送することが好ましい。 The disposable pants 300 are formed while the first elongated body 75 serving as the front body 110 and the second elongated body 76 serving as the rear body 120 are sequentially conveyed. At this time, the first elongated body 75 and the second elongated body 76 flow in a state in which a predetermined tension is applied in the transport direction (direction A in FIG. 15). In other words, the first elongated body 75 and the second elongated body 76 flow in the transport direction in a state in which the first elongated body 75 and the second elongated body 76 are expanded by an amount corresponding to the tension compared with the natural length. Although the amount of extension can be set arbitrarily, it is preferable to carry the first elongated body 75 and the second elongated body 76 in a state of being appropriately stretched (for example, a state of being stretched by 20%).
　このように、適度に伸長した状態で第１長尺体７５及び第２長尺体７６が搬送方向に流れていくと、第１の工程において、第１長尺体７５の一方の側縁及び第２長尺体７６の一方の側縁がそれぞれ折り板７７，７８によって折り曲げられ、折り曲げたことによって重なる部分で接合され、ウェスト部１１５、１２５が形成される。 As described above, when the first elongated body 75 and the second elongated body 76 flow in the transport direction in a state of being appropriately stretched, in the first step, one side edge of the first elongated body 75 and One side edge of the second elongated body 76 is bent by the folding plates 77 and 78, respectively, and the bent portions are joined at overlapping portions to form waist portions 115 and 125.
　ここで、股下部１６０は、第１長尺体７５及び第２長尺体７６が搬送される工程とは別の工程で製造されている。即ち、股下部１６０に関しては、生地１が長方形状に切断された状態で用意される。 Here, the crotch portion 160 is manufactured in a process different from the process in which the first elongated body 75 and the second elongated body 76 are transported. That is, regarding the crotch portion 160, the dough 1 is prepared in a state of being cut into a rectangular shape.
　次に、用意された股下部１６０は、平行に搬送される第１長尺体７５及び第２長尺体７６の間に架け渡されるように配置される。このとき、股下部１６０は、第１長尺体７５及び第２長尺体７６の搬送方向と直交する方向（図１５中、Ｂ方向）に沿って伸長するように配置される。第１長尺体７５と股下部１６０との重なり部分が接合され、また、第２長尺体７６と股下部１６０との重なり部分が接合される。これにより、それぞれ接合線１６１、１６２が形成される。 Next, the prepared crotch portion 160 is disposed so as to be bridged between the first elongated body 75 and the second elongated body 76 conveyed in parallel. At this time, the crotch portion 160 is arranged to extend along a direction (direction B in FIG. 15) orthogonal to the transport direction of the first elongated body 75 and the second elongated body 76. The overlapping portions of the first elongated body 75 and the crotch portion 160 are joined, and the overlapping portions of the second elongated body 76 and the crotch portion 160 are joined. Thus, bonding lines 161 and 162 are formed.
　そして、次の工程において、股下部１６０の中央線が折り曲げ線となるように、第１長尺体７５と第２長尺体７６とが互いに重なる位置に配置される。また、このように重ねられた後に、第１長尺体７５と第２長尺体７６とが接合される。次に、これら接合された箇所においてカッター等により切断され、使い捨てパンツ３００が形成される。この接合と切断は、ほぼ同時に行われるようにしてもよい。 Then, in the next step, the first elongated body 75 and the second elongated body 76 are arranged at an overlapping position so that the center line of the crotch portion 160 is a bending line. Also, after being stacked in this manner, the first elongated body 75 and the second elongated body 76 are joined. Next, these joined portions are cut by a cutter or the like to form disposable pants 300. The bonding and cutting may be performed substantially simultaneously.
　このようにして切断されると、第１長尺体７５及び第２長尺体７６において適度に伸長された状態が解除され、張力の付与されていない状態になる。張力が付与されなくなると、使い捨てパンツ３００が引っ張られた状態から収縮するが、これは、通常の着用時前の状態であり、通常の着用時の状態では、股下部の収縮した状態が解消されるので、見栄えがよくなる。 When cut in this manner, the first elongated body 75 and the second elongated body 76 are released from the state of being appropriately stretched, and are in a state where no tension is applied. When tension is not applied, the disposable pants 300 contract from being pulled, but this is the state before normal wearing, and in the normal wearing state, the crotchless state is eliminated Looks better.
　図示せぬ次の工程において、使い捨てパンツ３００は、裏表を逆にする裏返しが行われ、さらに折り畳み、袋詰めなどが行われる。 In the next step (not shown), the disposable pants 300 are turned upside down, and further folded, bagged, and the like.
　また、上記実施形態１～３における使い捨てパンツは、着用時に使い捨てパンツと着用者の股下との間に体液を吸収する吸収体を配置することができる。これにより、使い捨てパンツをおむつの外装体として利用することができる。 In the disposable pants according to the first to third embodiments, an absorber that absorbs body fluid can be disposed between the disposable pants and the crotch of the wearer when worn. Thereby, a disposable pants can be utilized as an exterior body of a diaper.
　（実施形態４）
　図１６は、本発明の実施形態４に係る使い捨てパンツ４００の着用状態における斜視図である。図１７は、使い捨てパンツ４００の未着用状態における正面図である。 (Embodiment 4)
FIG. 16 is a perspective view of the disposable pants 400 according to the fourth embodiment of the present invention in a worn state. FIG. 17 is a front view of the disposable pants 400 in a non-worn state.
　使い捨てパンツ４００は、前身頃２１０、後身頃２２０、股下部２６０の各生地片から主に構成される。使い捨てパンツ４００は、着用時において、着用者との間に体液を吸収する吸収体が配置される。 The disposable pants 400 are mainly composed of the fabric pieces of the front body 210, the back body 220, and the crotch portion 260. When the disposable pants 400 are worn, an absorber that absorbs body fluid is disposed between the disposable pants 400 and the wearer.
　前身頃２１０は、例えば矩形状の生地１よりなり、矩形状の生地の１つの長辺を所定の長さ分内側に折り返して形成されたウェスト部２１５を有する。前身頃２１０は、着用時に横方向（図１７中、矢印Ｄ方向）に伸張するように生地１が配置される。また、前身頃２１０には、係合手段としての面ファスナー２８０が接合される。具体的には、前身頃２１０の非肌面側に、面ファスナー２８０のうち、丸い輪状の繊維が多数織り込まれたループ面２８１が接合される。 The front body 210 is made of, for example, a rectangular cloth 1, and has a waist portion 215 formed by folding back one long side of the rectangular cloth by a predetermined length. In the front body 210, the fabric 1 is disposed so as to extend in the lateral direction (the direction of the arrow D in FIG. 17) when worn. Further, a surface fastener 280 as an engagement means is joined to the front body 210. Specifically, on the non-skin surface side of the front body 210, a loop surface 281, in which a large number of round ring-shaped fibers are woven, of the surface fastener 280 is joined.
　また、後身頃２２０は、前身頃２１０と同様、例えば矩形状の生地１よりなり、矩形状の生地の１つの長辺を所定の長さ分内側に折り返して形成されたウェスト部２２５を有する。後身頃２２０は、着用時に横方向（図１７中、矢印Ｄ方向）に伸張するように生地１が配置される。 Further, the back body 220 is made of, for example, a rectangular cloth 1 like the front body 210, and has a waist portion 225 formed by folding back one long side of the rectangular cloth by a predetermined length. In the back body 220, the fabric 1 is disposed so as to extend in the lateral direction (the direction of the arrow D in FIG. 17) when worn.
　前身頃２１０の一方の短辺と後身頃２２０の一方の短辺とが接合され、前身頃２１０の他方の短辺と後身頃２２０の他方の短辺とが接合される。すなわち、前身頃２１０と後身頃２２０とを重ねたとき、向かい合う短辺同士が接合される。 One short side of front body 210 and one short side of back body 220 are joined, and the other short side of front body 210 and the other short side of back body 220 are joined. That is, when the front body 210 and the back body 220 are stacked, the facing short sides are joined.
　股下部２６０は、例えば矩形状の生地１よりなり、着用時に主に上下方向及び又は前後方向（図１７中、矢印Ｅ方向）に伸張するように配置される。股下部２６０は、一辺が後身頃２２０と接合される。具体的には、股下部２６０は、一辺が後身頃２２０の脚部開口部側の端部付近に接合される。 The crotch portion 260 is made of, for example, a rectangular fabric 1, and is disposed so as to extend mainly in the vertical direction and / or the longitudinal direction (the direction of arrow E in FIG. 17) when worn. The crotch portion 260 is joined to the back body 220 at one side. Specifically, one side of the crotch portion 260 is joined near the end on the leg opening side of the back body 220.
　また、股下部２６０には、係合手段としての面ファスナー２８０が接合され、前身頃２１０に接合されたループ面２８１と係合する。具体的には、股下部２６０には、面ファスナー２８０のうち、多数の細かいかぎ状からなるフック面２８５が接合される。これにより、股下部２６０の前後方向における伸縮性を利用して、吸収体を装着した際に、着用者の体形に応じて、吸収体２７０を確実に押圧し、フィットさせることができる。また、着用者を介護する介護者が吸収体２７０及び使い捨てパンツ４００を装着させる際にも、介護者が容易に装着させることができるので、介護者の負担を軽減することができる。また、股下部２６０の一方端を着脱自在とすることにより、この一方端を外した場合には、左右の脚部開口部を連通させた大きな開口部とすることができ、例えば、大人用の便失禁に対応した幅広の吸収体を交換する際にも、使い捨てパンツ４００を脱がすことなく、介護者が比較的容易に吸収体を交換することができる。 Also, a hook-and-loop fastener 280 as an engagement means is joined to the crotch portion 260 and engaged with a loop surface 281 joined to the front body 210. Specifically, a large number of fine hook-like hook surfaces 285 of the surface fastener 280 are joined to the crotch portion 260. As a result, when the absorber is attached using the stretchability of the crotch portion 260 in the front-rear direction, the absorber 270 can be reliably pressed and fitted according to the wearer's body shape. In addition, even when a caregiver who cares for the wearer wears the absorber 270 and the disposable pants 400, the caregiver can easily wear it, so the burden on the caregiver can be reduced. Further, by making one end of the crotch portion 260 detachable, when the one end is removed, the left and right leg openings can be made a large opening communicating with each other, for example, for adults Even when replacing the wide absorbent body corresponding to fecal incontinence, the caregiver can relatively easily exchange the absorbent body without taking off the disposable pants 400.
