Preparation method of full-wool wash and wear fabric

Abstract

The invention relates to a preparation method of a full-wool wash and wear fabric. The preparation method comprises the following steps: dyeing, re-washing, re-combing and pre-spinning, yarn spinning,self-spooling, doubling, two-for-one twisting, yarn steaming, warping, weaving, gray fabric checkout, after finishing and finished product obtaining. The full-wool wash and wear fabric is made from 70S Australian wool, wherein in the weaving step, a selected fabric weave is a 3 / 1 warp backed weave, an unclear shed is adopted, meanwhile, the overall height of heald frames of 3 / 1 warps is improved,the loading tension is properly increased, and a cold sizing technology is adopted to reduce hairiness so as to reduce the adhesion phenomenon of the warps when a warping beam is inverted; in the after finishing step, open-width wool fabric scouring and boiling are adopted. According to the preparation method, wool fiber is taken as a main raw material and is processed through processes of top dyeing, spinning, weaving, after finishing and the like. By adopting technological measures such as backed weave design, high-warp-density weaving, yarn cold-sizing and unclear shed adoption, after-processing technologies such as open-width wool fabric scouring, singeing and shrinkage prevention are optimized, and excellent elastic resilience and crease resilience of the product are ensured.

Description

technical field [0001] The invention relates to the technical field of production of washable and wearable fabrics, in particular to a preparation method of full wool washable and wearable fabrics. Background technique [0002] With the continuous improvement of people's quality of life, the handle and requirements for fabrics are getting higher and higher. Traditional woolen garments must be dry-cleaned and ironed, which does not meet the needs of modern life for convenience and comfort. In addition, the scope of use of woolen fabrics is expanding day by day, from the past to the development of outerwear and suits in the past to today's thin wool trousers, thin wool shirts, wool knitted underwear, etc. As far as clothing materials are concerned, no matter how the clothing style changes, people always It tends to be required to have the advantages of non-ironing, light weight, and novelty.

Problems solved by technology

In addition, the scope of use of woolen fabrics is expanding day by day, from the past to the development of outerwear and suits in the past to today's thin wool trousers, thin wool shirts, wool knitted underwear, etc. As far as clothing materials are concerned, no matter how the clothing style changes, people always It tends to be required to have the advantages of non-ironing, light weight, and novelty. The machine-washing resistance of wool fabrics is very poor, and felting occurs when it is mechanically stirred in water. The felting shrinkage rate is as high as 60%, and its excellent wearability is lost. Therefore, washable and wearable fabrics are more and more popular among people. In response to this type of demand, it is urgent to develop a preparation method for all-wool washable and wearable fabrics.
