さらにこの弾性部材接合領域60の弾性部材52の他方側面に、長尺紙54の一方側面が接合され、さらに長尺紙54の他方側面に第2の長尺不織布56が接合される。これにより図12(b)に示したような断面構造を有する複合シート70が形成される(複合シート形成工程)。なお、符号28は、使用者が使い捨て下半身用衣料10を着用した際に、肌と接する肌接触面であるが、第2の長尺不織布56が肌接触面であってもよいものである。
Further, one side surface of the long paper 54 is joined to the other side surface of the elastic member 52 in the elastic member joining region 60, and the second long nonwoven fabric 56 is joined to the other side surface of the long paper 54. Thereby, the composite sheet 70 having a cross-sectional structure as shown in FIG. 12B is formed (composite sheet forming step). In addition, although the code | symbol 28 is a skin contact surface which contacts skin when a user wears the clothing 10 for disposable lower body, the 2nd elongate nonwoven fabric 56 may be a skin contact surface.
複合シート70は、図12(a)に示したように、搬送方向と直交する幅方向に、一方側端部70aから他方側端部70bに向かって順に、前身頃相当部分20c,前胴部相当部分22c,股下部相当部分24a,後胴部相当部分22d,後身頃相当部分20dを有している。

The composite sheet 70 may be simply laminated as it is, but if the composite sheet 70 is pressed by the pressing means 72 from the thickness direction, the long paper 54 can be softened in particular, and the completed disposable lower body is used later. The comfort of the garment 10 can be improved.
押圧手段72としては特に限定されるものではないが、例えば平面ロール,凹凸ロールなどが挙げられる。
The pressing means 72 is not particularly limited, and examples thereof include a flat roll and an uneven roll.
複合シート70を構成する各部材間の接合については、特に限定されるものではなく、公知の接合手段76,78を用いることができるが、例えばホットメルト系接着剤、有機溶剤系接着剤又は水溶性接着剤を用いることが好ましく、中でもホットメルト系接着剤がより好ましい。

These adhesives can be applied by at least one of planar coating, linear coating, dot coating, continuous coating, intermittent coating, spiral coating, wave coating, block coating, stripe coating, and staggered coating. It is preferable.
なお、弾性部材52として複数の弾性糸条58を用いた場合には、図12(b)に示したように、各弾性糸条58の外表面に接合手段76として接着剤を塗布し、この状態で弾性部材52の一方側面に第1の長尺不織布50を接合し、さらに弾性部材52の他方側面に長尺紙54の一方側面を接合すれば良い。本図において、長尺紙54はジグザグに表現されているが、これは後述するエンボス加工によって施された凹凸を便宜的に表したものであって、形状を限定するものではないものである。
When a plurality of elastic yarns 58 are used as the elastic member 52, an adhesive is applied as the joining means 76 to the outer surface of each elastic yarn 58, as shown in FIG. In this state, the first long nonwoven fabric 50 may be bonded to one side surface of the elastic member 52, and one side surface of the long paper 54 may be bonded to the other side surface of the elastic member 52. In this figure, the long paper 54 is expressed in a zigzag, but this is a convenient representation of the unevenness provided by embossing, which will be described later, and does not limit the shape.
また、第1の長尺不織布50の一方側面に形成された弾性部材接合領域60は、第1の長尺不織布50の一方側面の全面に設けられているか、または最低限、第1の長尺不織布50の一方側面の一部分に設けられている。
Moreover, the elastic member joining area | region 60 formed in the one side surface of the 1st elongate nonwoven fabric 50 is provided in the whole surface of the 1 side surface of the 1st elongate nonwoven fabric 50, or at least 1st elongate nonwoven fabric 50 It is provided on a part of one side surface of the nonwoven fabric 50.
弾性部材接合領域60が第1の長尺不織布50の一方側面の全面に設けられていれば、最終製品である使い捨て下半身用衣料10のウエスト部20,胴部22,股下部24の全ての部位が図1または図2において左右の方向に伸縮性を有することとなるため、使用者に心地良くフィットする使い捨て下半身用衣料10を製造することができる。
If the elastic member joining region 60 is provided on the entire surface of one side of the first long nonwoven fabric 50, all the parts of the waist part 20, the trunk part 22, and the crotch part 24 of the disposable lower body clothing 10 that is the final product. However, since it has elasticity in the left-right direction in FIG. 1 or FIG. 2, the disposable lower body garment 10 that fits comfortably to the user can be manufactured.
また、弾性部材接合領域60が一部分に設けられていても、最終製品である使い捨て下半身用衣料10の少なくとも股下部24周辺が伸縮性を有するよう、この一部分の弾性部材接合領域60が股下部24周辺に位置するようにしておけば、最低限、股下部24周辺が図1または図2において左右の方向に伸縮性を有することとなるため、使用者に心地良くフィットする使い捨て下半身用衣料10を製造することができる。
Further, even if the elastic member joining region 60 is provided in a part, the elastic member joining region 60 of this part is formed so that at least the periphery of the crotch part 24 of the disposable lower body garment 10 which is the final product has elasticity. As long as it is located in the periphery, the periphery of the crotch part 24 has elasticity in the left and right directions in FIG. 1 or FIG. 2, so that the disposable lower body garment 10 that fits comfortably to the user can be provided. Can be manufactured.
ここで弾性部材52の他方側面に接合される長尺紙54は、複合シート70が形成される前に、予めエンボス手段12にてエンボス加工が施されると良い。
Here, the long paper 54 bonded to the other side surface of the elastic member 52 may be embossed by the embossing means 12 in advance before the composite sheet 70 is formed.
長尺紙54へのエンボス加工により、長尺紙54に脆弱部としてしわを設けたり、抜き孔、パンチング、適度な孔、裂孔、切り込みなどを施すことができる。
By embossing the long paper 54, wrinkles can be provided on the long paper 54 as weak parts, punching holes, punching, appropriate holes, fissures, incisions, and the like.
しわは、複合シート70の引張りに追随して長尺紙54も伸縮するようにするためのものであるとともに、後述する印刷手段14での印刷では表現できないような、立体的なデザイン、見る角度によりニュアンスの異なるデザインなどを表現するためのものでもある。さらに別の効果としては、使い捨て下半身用衣料10において、使用者の肌や陰部が透けて見えてしまうことを防止する側面もある。この際、遮光率75%以上であれば、使用者の肌や陰部が透けて見えることがなく、使用者の装着時における抵抗感を和らげることができる。
The wrinkles are intended to cause the long paper 54 to expand and contract following the pulling of the composite sheet 70, as well as a three-dimensional design and viewing angle that cannot be expressed by printing with the printing means 14 described later. It is also for expressing designs with different nuances. As another effect, in the disposable lower body garment 10, there is also a side face that prevents the user's skin and shadow from being seen through. At this time, if the light shielding rate is 75% or more, the user's skin and shadow are not seen through, and the resistance feeling when worn by the user can be eased.
また孔は、通気性を向上させたり、長尺紙54に伸縮性を持たせるためのものである。
Also, the hole is for improving air permeability and giving the long paper 54 elasticity.
エンボス加工によって付されるしわの形状例としては、例えば図13に示した斜視図のように、断面形状として搬送方向に波打つように繰り返し付された波状の凹凸が挙げられる。なお、エンボス加工は、長尺紙54の全面に設けられていても、部分的に設けられていても良く、特に限定されるものではなく、所望の位置を適宜選択して設けることが望ましい。
As an example of the shape of a wrinkle applied by embossing, for example, as shown in the perspective view of FIG. 13, a wavy unevenness repeatedly applied so as to wave in the conveying direction as a cross-sectional shape can be mentioned. The embossing may be provided on the entire surface of the long paper 54 or may be provided partially. The embossing is not particularly limited, and it is desirable to appropriately select a desired position.
このようなエンボス加工が施される長尺紙54は、エンボス加工の前に印刷手段14にて印刷がなされても良い。
The long paper 54 subjected to such embossing may be printed by the printing means 14 before embossing.
印刷は、例えばインクジェット、フレキソ印刷などの手法を用いることができ、特にフレキソ印刷を用いることが好ましい。また印刷の表面は、ニス引き加工を行ったり、バインダーを加えたりすることにより、色落ち防止処理がなされていてもよい。バインダーとしては、PVA、CMC、EVA、アクリル、ラッカーなど、公知の材料が挙げられる。また、色落ち防止処理がなされているインクを使用することもできる。
For printing, for example, a method such as ink jet or flexographic printing can be used, and it is particularly preferable to use flexographic printing. Further, the printing surface may be subjected to color fading prevention treatment by varnishing or adding a binder. Examples of the binder include known materials such as PVA, CMC, EVA, acrylic, and lacquer. Ink that has been subjected to color fading prevention treatment can also be used.
なおフレキソ印刷法では、版と長尺紙54との間の接触面積が小さくて済む、印圧が低いなどの利点がある。このため、版から長尺紙54を剥がし易く、特に薄い長尺紙54に印刷をする場合に好適である。
Note that the flexographic printing method has advantages such as a small contact area between the plate and the long paper 54 and a low printing pressure. For this reason, it is easy to peel the long paper 54 from the plate, and it is particularly suitable when printing on the thin long paper 54.
また、フレキソ印刷法は、使えるインクの種類が多く、この点で特にノズルを通してインクを吐出させるインクジェット印刷法と比べ、インク粘度に縛られるなどの弊害が少なく自由度が高い。なお、エンボス加工後の長尺紙54に印刷として絵柄を表す場合、版によって印刷される絵柄は、弾性部材52の伸縮方向(搬送方向)に長尺紙54を引き延ばしておくことで、使用時に使い捨て下半身用衣料10の外観に所望の絵柄が表れるようにすることができる。
In addition, the flexographic printing method has many types of ink that can be used. In this respect, the flexographic printing method has less adverse effects such as being restricted by the ink viscosity and has a high degree of freedom compared to the ink jet printing method in which ink is ejected through a nozzle. In addition, when a pattern is expressed as a print on the long paper 54 after embossing, the pattern printed on the plate can be used by extending the long paper 54 in the expansion / contraction direction (conveying direction) of the elastic member 52. A desired pattern can appear on the appearance of the disposable lower body garment 10.
なお、印刷を行う際の原料中に、消臭剤、虫避剤、香料、防水剤、抗菌剤、防汚剤、柔軟剤の少なくとも一つを含有させても良い。
It should be noted that at least one of a deodorant, an insect repellent, a fragrance, a waterproofing agent, an antibacterial agent, an antifouling agent and a softening agent may be contained in the raw material for printing.
