Description

外層シート5と止着部材6とは接着剤を介して接着されている。接着剤としては、ホットメルト接着剤等の公知のものを用いることができる。
外層シート5と止着部材6との接合強度を確保しつつ、おむつ1の非肌対向面における風合いをより向上させる観点から、外層シート5と止着部材6とを接着する接着剤の使用量は、10g/m以上、より好ましくは15g/m以上であり、また好ましくは30g/m以下、より好ましくは25g/m以下であり、また好ましくは10g/m以上30g/m以下、より好ましくは15g/m 以上25g/m以下である。
The outer layer sheet 5 and the fastening member 6 are adhered via an adhesive. A known adhesive such as a hot-melt adhesive can be used as the adhesive.
From the viewpoint of further improving the texture of the non-skin facing surface of the diaper 1 while securing the bonding strength between the outer layer sheet 5 and the fastening member 6, the amount of the adhesive used for bonding the outer layer sheet 5 and the fastening member 6 is 10 g/m 2 or more, more preferably 15 g/m 2 or more, more preferably 30 g/m 2 or less, more preferably 25 g/m 2 or less, and preferably 10 g/m 2 or more and 30 g/m 2 or more 2 or less, more preferably 15 g/m 2 or more and 25 g/m 2 or less.

第1面61及び第2面62の表面接触面積率をより容易に異ならせる観点から、止着部
材6は、第1面61を形成する層及び第2面62を形成する層が積層した、2層以上の積層構造を有していることが好ましい。斯かる形態の止着部材6として、メカニカルファスナーのメス材と不織布とが積層したもの、例えば係合突起が直接係合可能な不織布と他の不織布とが積層したもの等が挙げられる。
止着部材6が前記積層構造を有している場合、第2面62の表面接触面積率を第1面61よりも容易に高くする観点から、第2面62を形成する層の坪量は好ましくは5g/m以上、より好ましくは10g/m以上であり、また好ましくは35g/m以下、より好ましくは30g/m以下であり、また好ましくは5g/m以上35g/m以下、より好ましくは10g/m 以上30g/m以下である。
From the viewpoint of making the surface contact area ratios of the first surface 61 and the second surface 62 different more easily, the fastening member 6 is formed by laminating a layer forming the first surface 61 and a layer forming the second surface 62. It preferably has a laminated structure of two or more layers. Examples of such a fastening member 6 include a laminate of a female material of a mechanical fastener and a non-woven fabric, for example, a laminate of a non-woven fabric with which the engaging protrusions can be directly engaged and another non-woven fabric.
When the fastening member 6 has the laminated structure, the basis weight of the layer forming the second surface 62 is It is preferably 5 g/m 2 or more, more preferably 10 g/m 2 or more, more preferably 35 g/m 2 or less, more preferably 30 g/m 2 or less, and more preferably 5 g/m 2 or more and 35 g/m 2 or more. 2 or less, more preferably 10 g/m 2 or more and 30 g/m 2 or less.
