example 1

[0148] Example 1: Low Melt Fiber: Bicomponent Fiber

[0149] Low melting point fiber LOMELA manufactured by Huvis TM Used to make composite yarns and fabrics. LOMELA(TM) is a low melting bicomponent filament with a core and sheath structure. The sheath is a low melt polymer and the core is conventional polyester. During the heat activation process, the fibers can readily develop the bonding function that requires a stable form. A yarn with 36 filaments is 75 denier. The melting temperature of the sheath component part was 165°C. When the heating temperature is lower than 150°C, the fibers look and behave as regular polyester fibers. When the temperature reaches 150°C or higher, the low melting skin begins to soften and melt. When the temperature reaches 165°C, the sheath part is completely melted and fused with the core fiber. The individual 36 filaments are fused and bonded together to form a single strand. It also connects and bonds with adjacent rigid fibers and ela...

[0150] Example 2: Low melting point fiber: single component fiber

[0151] Monocomponent fibers comprising "polyolefin" polymers are used as low-melt fibers. The fibers were spun into one filament of 40D. The fiber starts to melt at 135.65°C and reaches the melting peak at 146.26°C. The thermal activation process may be performed at a temperature in the range of about 120°C for a period of 5 seconds to several minutes. After melting, it bonds with adjacent rigid and elastic fibers to form a cross-linked structure within the fabric.

[0152] Example 3: Single Core Yarn

[0153] 40D The fiber core is surrounded by 75D / 36f low-melt bicomponent yarn. Elongated at 3.0X during coring fiber. Yarns have high recovery and surface gloss aesthetics due to the low melting point bicomponent fibers. This core yarn can be used in hosiery, pantyhose, socks as well as knitting and weaving applications.

Abstract

The present invention provides an easily settable stretch fabric comprising three types of yarns: rigid fibers, elastic fibers and low-melt fibers, wherein the low-melt fibers comprise A low melting point polymer that melts at temperatures between 200°C, which are higher than those used in common textile processes and domestic laundry, but lower than those used for heat setting elastane. The low-melt fibers may be selected from the group of fibers made from modified polyesters, nylons and polypropylenes and copolymers therefrom in staple or filament form.

Description

[0001] Cross References to Related Applications\ [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 096,762, filed December 24, 2014; and U.S. Provisional Application No. 62 / 198,243, filed July 29, 2015, the disclosures of which are specifically It is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to an easily settable stretch fabric comprising a first type 1 of rigid fibers, a second type 2 of elastic fibers and a third type of yarn 3 of low-melt fibers, wherein the low-melt The fibers comprise low melting point polymers that melt at lower temperatures than the heat setting temperature of the elastic fibers. Stabilizes fabrics at low temperatures with low shrinkage without compromising the recovery power of elastane fibers. The level of fabric stretch can be adjusted through a heat activation process. The fabric within the garment can have altered stretch levels in predetermined loc...
