Embodiment 1

[0106] Example 1 - Functional double layer fabric providing thermal functionality

[0107] On the top layer, the warp is cotton in a yarn size 10’s (cotton count) and the weft is a yarn size 14’s (available from Invista) hollow yarn. The fabric construction is a 70*40 plain weave which provides insulation.

[0108] On the bottom layer, the warp is acrylic in a yarn size 10's, the weft is a wool in a yarn size 14's, and the fabric construction is a 70*40 3 / 1 twill weave that provides warmth.

Embodiment 2

[0109] Example 2 - Functional Double Layer Fabric Providing Abrasion Resistance and Warming Properties

[0110] On the top layer, the warp is nylon with yarn size 400D (filament), the weft is polytetrafluoroethylene (PTFE) with yarn size 300D, and the fabric construction is 60*40 2 / 1 twill, which can provide abrasion resistance sex.

[0111] On the bottom layer, the warp is kapok (natural hollow fiber) in yarn size 500D and the weft is infrared (IR) reflective polyester in yarn size 300D (the weft is conventional polyester where IR reflective prints such as aluminum are covered printed on the inner side of the base layer to provide warmth), the fabric construction is 60*40 3 / 1 twill, which can provide warmth.

Embodiment 3

[0112] Example 3 - Functional Double Layer Fabric Providing Water Repellency and Cooling

[0113] On the top layer, the warp (yarn size 10’s) and weft yarns (yarn size 12’s) are cotton treated with a fluorocarbon chemical to provide water repellency, and the fabric construction is a broken twill or ripstop weave, 60*40.

[0114] On the bottom layer, the warp yarns are polyester 450D with carbon-based particles to provide high thermal conductivity, the weft yarns are polyester 400D with oval-scalloped filament cross-sections to provide improved moisture absorption, and the fabric construction is 60*40 Sateen, which can provide cooling.

Abstract

A multilayer fabric includes at least a first woven fabric layer and a second woven fabric layer tacked to the first woven fabric layer. The first woven fabric layer provides a first functionality tothe multilayer fabric, the second woven fabric layer provides a second functionality to the multilayer fabric, and the first functionality is different from the second functionality. A method for forming a multilayer fabric includes weaving a first fabric layer on a loom, the first fabric layer having a first functionality, weaving at least a second fabric layer on the loom, the second fabric layer having a second functionality different from the first functionality, and tacking the second fabric layer to the first fabric layer while the first fabric layer and the second fabric layer are on the loom. The multilayer fabric may include multiple fabric layers, such as from 2 to 8 fabric layers.

Description

technical field [0001] The present disclosure relates to multi-layer woven fabrics, and in particular to multi-layer and multi-functional woven fabrics in which each layer provides different functionality to the woven fabric. Background technique [0002] Various forms of double layer fabrics are available in the apparel market. In one form, two or more individually woven or knitted fabrics are combined using lamination bonding or by stitching / sewing the fabrics together. Another form is double fleece fabric. While garments made from these types of constructions may provide certain functions, such as warming, wind protection, etc., they also suffer from various drawbacks. For example, the fabric is bulky, the process of making the fabric is costly and inefficient, the fabric lacks breathability (particularly in laminated constructions including films such as polytetrafluoroethylene), and the aesthetics of the fabric can be compromised. [0003] Aspects of the present disc...
