Embodiment Construction

[0041] The present invention provides a composite elastic yarn composed of an elastic filament combined with hydrophobic fibers and hydrophilic fibers, and a moisture management fabric made therefrom. Techniques using conventional spinning equipment with minimal modifications can be used to make the composite elastic yarns of the present invention. One of the preferred processes is the use of air jet texturing equipment. If this equipment is used under precisely controlled conditions, the elastic filaments and hydrophilic fibers in the resulting composite yarn are mainly located near the warp axis of the composite yarn while the hydrophobic fibers are concentrated in the periphery. The elastic filament is at or near the center of the composite filament and is surrounded by hydrophilic fibers concentrated around it, while between the center and peripheral regions of the yarn there is a zone containing both hydrophilic fibers and hydrophilic fibers. Mixed regions of fibers.

Abstract

A composite textile yarn and a moisture management elastic fabric made therefrom, the yarn comprising an elastic filament and hydrophilic fibers embedded at the yarn center within a matrix of hydrophobic fibers such that the hydrophobic fibers are concentrated at the periphery of the yarn, a transition area between the hydrophobic fibers concentrated about the elastic filament at the yarn center and the peripheral hydrophobic yarns in which both fiber types are present.

Description

[0001] This application is related to the pending application No. 10 / 112,957 titled "Composite Yarn and Moisture Control Fabric Made Therefrom" filed by the same applicant and filed on the same date as this application. technical field [0002] The present invention generally relates to a composite elastic yarn for use in forming moisture management fabrics composed of fibers having elastic properties. More specifically, it relates to improved moisture barrier textile composite yarns comprising elastic filaments and hydrophilic fibers embedded in a matrix of one or more hydrophobic fibers. In addition, the present invention relates to improved moisture management elastic fabrics and garments made from the composite yarns described above alone or in combination with other yarns. Background technique [0003] In recent years, "structural fabrics" (also known as "engineered fabrics") have become very popular in many commercial applications. A particularly important branch of s...
