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.

Embodiment Construction

[0008] The present invention will be further described below in conjunction with embodiment.

[0009] The production process flow of multi-strand high-twisted knitting yarn of the present invention is:

[0010] Pre-treatment: Pre-treatment includes pre-treatment of silk, pre-treatment of acrylic filament, pre-treatment of bamboo fiber and pre-treatment of wood pulp fiber; the pre-treatment of silk is: the eighth single-twisted monofilaments at the same time, the single-twisted monofilaments are parallel-twisted with every two single-filaments as a group, and the four groups of yarns obtained after parallel-twisted are also parallel-twisted again with every two groups as a unit. And obtain two plied yarns, carry out final parallel twisting to these two plied yarns, finally obtain the silk with twist number 1600 twists, then winding, silk is twisted with Z twist mode in the whole twisting process; The pre-treatment of the filament is: firstly, the multi-strand filaments that ma...

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 production process of multi-strand high-twist knitting yarn. 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 absorption, shrink resistance, and wa...
