Highly twisted multi-strand knitting yarn and its production technology

Abstract

A high-twisted multi-strand knitting yarn is composed of three fibres, and features that its one fibre is acrylic fibre filament and another two are chosen from silk, bamboo fibre and wood pulp fibre. Its production technology includes pre-treating and double-twisting. The fabric made of it features high air permeability, hydroscopicity, and shrinking resistance.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a multi-strand high-twist knitting yarn and a production process thereof. Background technique [0002] The plied yarn on the market is generally two-ply, and this two-ply yarn is composed of a single raw material at first, and it can only be composed of one or two kinds of raw materials. Two chemical fiber filaments of the same raw material are twisted, or two chemical fiber filaments of different raw materials are twisted. The drawback brought by the singleness of the raw materials is that when the two ply yarns are used to weave fabrics, the fabrics woven are relatively poor in terms of air permeability, water absorption, shrink resistance, and wash resistance. Secondly, the twisting process of this two-ply yarn is also relatively simple, and the twist is also low. The deficiencies brought also make the woven surface poor in terms of air permeability, water abs...

AI Technical Summary

Problems solved by technology

The disadvantages caused by the singleness of the raw material composition are: when the two-ply yarn is used to weave fabrics, the fabrics woven are poor in terms of air permeability, water absorption, shrinkage resistance, and wash resistance.

Secondly, the twisting process of this two-ply yarn is also relatively simple, and the twist is also low. The deficiencies brought about also make the woven surface poor in terms of air permeability, water absorption, shrink resistance, wash resistance, etc.
