US 12,005,691 B2 · Recyclable, asymmetrical-faced composite nonwoven textile having varied denier

Abstract

Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

Dependent claims

An asymmetrical-faced composite nonwoven textile having a first face and an opposite second face, the asymmetrical-faced composite nonwoven textile comprising:

a first entangled web of fibers having a first number of fibers per cm2 with a first denier and a second number of fibers per cm2 with a second denier, wherein a ratio of the first denier to the second denier is in a range of from about 1.5:1 to about 2:1, the first entangled web of fibers forming, at least in part, the first face;
a second entangled web of fibers having a third number of fibers per cm2 with a third denier and a fourth number of fibers per cm2 with a fourth denier, wherein a ratio of the third denier to the fourth denier is in a range of from about 0.3:1 to about 0.7:1, the second entangled web of fibers forming, 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.

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 the fibers of the second entangled web of fibers.

1 more element

A method of manufacturing an asymmetrical-faced composite nonwoven textile comprising:

positioning an elastomeric layer between a first web of fibers with a denier from about 1.2 D to about 3.5 D and a second web of fibers with a denier from about 0.6 D to about 1 D;
and
mechanically entangling a plurality of the fibers of the first web of fibers and a plurality of the fibers of the second web of fibers such that the first web of fibers becomes a first entangled web of fibers and the second web of fibers becomes a second entangled web of fibers, wherein subsequent to the mechanical entanglement step at least some of the fibers of the first entangled web of fibers and at least some of the fibers of the second entangled web of fibers extend through the elastomeric layer, and wherein the first entangled web of fibers forms, at least in part, a first face of the asymmetrical-faced composite nonwoven textile and the second entangled web of fibers forms, at least in part, an opposite second face of the asymmetrical-faced composite nonwoven textile.
