Process for making untwisted yarn cloth

Abstract

The invention is a manufacturing technology of untwisted gauze, which belongs to the field of fabric and mainly includes the following steps: twisted yarns are reversely enwound with polyvinyl alcohol to form twisted yarns; the twisted yarns are taken as weft yarns and normal yarns are taken as twist yarns to carry out weaving and form grey cloth; the grey cloth is placed into water for boiling-off, twist breaking and washing. The twist yarns play the roles of supporting and anti-pulling in fabric. Simultaneously, untwisted yarns are in the shape of ribbon sections in the fabric and becomes flat after being compressed, so that the coverage area of the fabric is enlarged. Therefore, the fabric with light weight looks thick, tight and fluffy, so as to show the characteristics of softness, warmness, lightness and transparency of the untwisted gauze like silky wool fabric.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a process for making woven fabrics by adopting untwisted yarns. Background technique [0002] Yarn is a textile fiber that is twisted by external force to make it entangled into a continuous linear object. In this process, the twist of the yarn itself will make the fibers entangled naturally and closely, which is very beneficial for weaving or knitting. Usually the higher the twist, the better the strength of the yarn. Therefore, whether it is the traditional hand-made textile industry or the textile industry produced by the chemical industry, the textile fibers must be twisted into yarns for further weaving, but the process of twisting spinning and weaving into cloth changes the texture of the fibers. Physical properties, so that the original soft, breathable, moisture absorption and other properties change. It can be seen that the amount of twisting is an important index to measure th...

AI Technical Summary

Problems solved by technology

When the fabric is in contact with a certain temperature, it will shrink highly, and if it is a garment, it will be severely deformed (its shrinkage rate is as high as 42%). Such a high shrinkage rate cannot be worn and applied at all.

(4) Untreated untwisted cloth cannot be dyed

Since the application of non-dyed cloth is greatly reduced, it will also affect the increase in color varieties

(5) The post-treatment process of untwisted cloth is complicated, the technical content is high, and the equipment requirements are harsh, so it is not suitable for production

After searching the relevant websites, there are only precedents of untwisted yarn and weaving towels with untwisted yarn, and there is no treatise on untwisted yarn weaving.
