A composite nonwoven textile having a first face and an opposite second face, the composite nonwoven textile comprising: a first entangled web of fibers that forms, at least in part, the first face, the first face comprising a plurality of discrete chemical bonding sites; a second entangled web of fibers that forms, at least in part, the second face; and an elastomeric layer positioned between the first entangled web of fibers and the second entangled web of fibers, wherein at least some of the fibers of the first entangled web of fibers extend through the elastomeric layer and are entangled with fibers of the second entangled web of fibers.

Method of making a spunbond nonwoven laminate

A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.

通过使用热粘合提高抗起球性的复合非织造织物

本文的各方面涉及适用于服装和其他抗起球制品的复合非织造织物。复合非织造织物可以通过将化学粘合剂应用于复合非织造织物的第一面和形成热粘合位点中的一种或多种进行整理。化学粘合剂和热粘合位点有助于固定纤维末端，并最大限度地减少毛球的形成。
