Method for slenderizing and permanently shaping uncolored wool

Abstract

The invention discloses a method for slenderizing and permanently shaping uncolored wool. The method adopts the scheme comprising the following steps of carding, preprocessing, twisting, slenderizing, shaping, untwisting, oxidizing, washing, drying and winding the uncolored wool with the fineness of 14.5 to 27.5mum in the form of wool tops to obtain the permanently shaped wool with the fineness of 12.5 to 22.5mum. The method has the advantages of simple process and high production efficiency, the obtained slenderized wool has silky luster and hand feeling, the fineness, the dispersion rate and the short-haired rate of the wool are equivalent to those of ordinary wool with the same fineness, and the fiber strength of the wool is improved by 20% in comparison with that of the ordinary wool with the same fineness.

Description

technical field [0001] The invention belongs to the technical field of wool textile fiber material engineering, and in particular relates to a method for stretching thinning and permanent setting of uncolored wool. Background technique [0002] In recent years, high-count and light textile and garment products have become more and more popular among consumers, but so far most of the raw materials used in light and light wool fabrics are fine wool in a natural state. These wools are expensive and the output is very limited. , especially cashmere fiber, not only the fiber itself is very precious, but only cashmere goats can grow cashmere, and cashmere goats will cause great damage to the ecological environment during their own breeding and growth. Therefore, people have been studying how to obtain ultra-fine wool artificially, including the following three methods: (1) sheep breed improvement technology for high-count wool, but this method is too long and expensive. (2) The w...

Problems solved by technology

[0002] In recent years, high-count and light textile and garment products have become more and more popular among consumers, but so far most of the raw materials used in light and light wool fabrics are fine wool in a natural state. These wools are expensive and the output is very limited. , especially cashmere fiber, not only the fiber itself is very precious, but only cashmere goats can grow cashmere, and cashmere goats will cause great damage to the ecological environment during their own stocking and growth

Therefore, people have been studying how to obtain ultra-fine wool artificially, including the following three methods: (1) sheep breed improvement technology for high-count wool, but this method is too long and expensive

(2) The wool fiber is corroded by chemical corrosion. Although this method can make the fiber thinner, it will damage a lot of materials, and the performance of the wool fiber will also be affected.

(3) Wool stretching and thinning is a very effective method for obtaining thinned wool at present, but most wool stretching and thinning technologies and products have the following disadvantages: First, the wool stretching is not sufficient, and the core wool in the wool strip is stretched. The fineness after stretching and thinning is generally about 2um larger than that of wool on the surface of the wool strip after stretching and thinning; Two times of setting are adopted, and the fineness of stretched and thinned wool is unstable; third, the stretched and thinned process takes a long time, high temperature, low production efficiency, high production cost, and the stretched and thinned wool is greatly damaged and feels rough. , the gloss is not strong
