Description
（湿式不織布）
湿式不織布は、主原料に合成繊維を用いて、製紙過程と同様に水に分散させた原料を抄紙機により抄紙することにより製造された不織布をさす。主原料として使用することのできる合成繊維としては、延伸ポリエステル系繊維、未延伸ポリエステル系繊維、ポリエステル系芯鞘型複合繊維、ポリプロピレン系芯鞘型複合繊維等があり、その他の繊維として、レーヨン・ポリノジック・キュプラ等の再生繊維、アセテート・トリアセテート・プロミックス等の半合成繊維を含有してもよい。湿式不織布は、乾式不織布との接着性の観点から熱融着性を有するバインダー繊維（未延伸ポリエステル系繊維、ポリエステル系芯鞘型複合繊維、ポリプロピレン芯鞘型複合繊維の１種類以上）を含む。また、延伸ポリエステル系繊維及び未延伸ポリエステル系繊維を主成分とすることで、引裂強度と積層時の接着強度を両立することができる。
(Wet non-woven fabric)
Wet non-woven fabric refers to a non-woven fabric produced by using synthetic fibers as the main raw material and using a paper machine to make the raw material dispersed in water in the same manner as in the papermaking process. The synthetic fibers that can be used as the main raw material, drawn polyester fibers, undrawn polyester fiber, polyester core-sheath type composite fibers, there are polypropylene-based core-sheath type composite fibers, other fibers, It may contain regenerated fibers such as rayon, polynosic and cupra, and semi-synthetic fibers such as acetate, triacetate and promix. The wet non-woven fabric contains binder fibers having heat-sealing properties from the viewpoint of adhesiveness to the dry non-woven fabric (one or more types of unstretched polyester fiber, polyester core-sheath composite fiber, and polypropylene core-sheath composite fiber). Further, by using the stretched polyester fiber and the unstretched polyester fiber as main components, it is possible to achieve both the tear strength and the adhesive strength at the time of lamination.
