Description
外側不織布層１２Ｓ及び内側不織布層１２Ｈの構成繊維としては、例えばポリエチレン又はポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維（単成分繊維の他、芯鞘等の複合繊維も含む）の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維等、特に限定なく選択することができ、これらを混合して用いることもできる。不織布層１２Ｓ，１２Ｈの柔軟性を高めるために、構成繊維を捲縮繊維とするのは好ましい。また、外側不織布層１２Ｓ及び内側不織布層１２Ｈの構成繊維は、親水性繊維（親水化剤により親水性となったものを含む）であっても、疎水性繊維若しくは撥水性繊維（撥水剤により撥水性となった撥水性繊維を含む）であってもよい。また、不織布は一般に繊維の長さや、シート形成方法、繊維結合方法、積層構造により、短繊維不織布、長繊維不織布、スパンボンド不織布、メルトブローン不織布、スパンレース不織布、サーマルボンド（エアスルー）不織布、ニードルパンチ不織布、ポイントボンド不織布、積層不織布（スパンボンド層間にメルトブローン層を挟んだＳＭＳ不織布、ＳＭＭＳ不織布等）等に分類されるが、これらのどの不織布も、外側不織布層１２Ｓ及び内側不織布層１２Ｈとして用いることができる。 The constituent fibers of the outer non-woven fabric layer 12S and the inner non-woven fabric layer 12H include, for example, olefin-based fibers such as polyethylene and polypropylene, polyester-based and polyamide-based synthetic fibers (including composite fibers such as core sheaths as well as single component fibers). In addition, recycled fibers such as rayon and cupra, natural fibers such as cotton, and the like can be selected without particular limitation, and these can be mixed and used. In order to increase the flexibility of the non-woven fabric layers 12S and 12H, it is preferable that the constituent fibers are crimped fibers. Further, even if the constituent fibers of the outer nonwoven fabric layer 12S and the inner nonwoven fabric layer 12H are hydrophilic fibers ( including those made hydrophilic by a hydrophilic agent), they are hydrophobic fibers or water-repellent fibers (depending on the water-repellent agent). It may be (including water-repellent fibers that have become water-repellent). In addition, the non-woven fabric generally has a short fiber non-woven fabric, a long fiber non-woven fabric, a spunbond non-woven fabric, a melt blown non-woven fabric, a spunlace non-woven fabric, a thermal bond (air-through) non-woven fabric, and a needle punch depending on the fiber length, the sheet forming method, the fiber bonding method, and the laminated structure. It is classified into non-woven fabrics, point-bonded non-woven fabrics, laminated non-woven fabrics (SMS non-woven fabrics having a melt blown layer sandwiched between spunbond layers, SMMS non-woven fabrics, etc.), and any of these non-woven fabrics should be used as the outer non-woven fabric layer 12S and the inner non-woven fabric layer 12H. Can be done.
