Study on shape retention properties of filament/staple fiber composite yarns and fabrics

Abstract

Purpose

With the improvement of living standards and acceleration of working pace, the shape retention property of textiles has attracted more attention. Yarn spinning is the first fundamental process in making textiles and apparel, and the properties of yarn influence the performance of textiles directly. Filament/staple fiber composite yarn is a kind of yarn spun by filament and staple fiber, and comprehensive qualities of yarn can be improved. Therefore, the purpose of this paper is to study the shape retention properties of filament/staple fiber composite yarns and corresponding fabrics.

Design/methodology/approach

Four kinds of composite yarn, core-spun yarn with one 50D SPH filament feeding, sirofil wrapped yarn with one 50D SPH filament feeding from left, sirofil wrapped yarn with one 50D SPH filament feeding from right, sirofil wrapped yarn with two 25D SPH filaments feeding from two sides, were spun. The qualities of spun yarns were measured. Then, corresponding two kinds of twill fabrics were woven by core-spun yarn and sirofil wrapped yarn with two filaments, respectively. The handle parameters, crease recovery, appearance leveling after washing, dimensional change rate after washing, strength and elongation and tensile elasticity were tested by using corresponding test instruments.

Findings

The tested results of spun yarn qualities show that comparing with the core-spun yarn, the evenness of sirofil wrapped yarn is improved, the hairiness is reduced, and the breaking strength and elongation are increased. Comparing with sirofil wrapped yarn with one filament, the evenness of sirofil wrapped yarn with two filaments is improved. The measured results of fabrics properties show that under the same weaving process, comparing to the fabric woven by core-spun yarn, the dimension of fabric woven by sirofil wrapped yarn is small after desizing, and warp and weft density is large. The possible reason is that the shrinkage of the SPH filament outside the sirofil wrapped yarn happens after desizing, which also makes the dimensional change rate after washing of the corresponding fabric large, and crease recovery poor.

Originality/value

In the paper, for improving the shape retention properties of the pure cotton woven fabric, one kind of SPH filament was added to the woven fabric by spinning filament/staple fiber composite yarns. Four kinds of composite yarn, core-spun yarn with one 50D SPH filament, sirofil wrapped yarn with one 50D SPH filament feeding from the left side, sirofil wrapped yarn with one 50D SPH filament feeding from the right side, sirofil wrapped yarn with two 25D SPH filaments feeding from two sides, were spun. Two kinds of twill fabrics were weaving by core-spun yarn and sirofil wrapped yarn with two filaments, respectively.
