A method of stretching thinning and permanent setting of colored wool

Abstract

The invention discloses a method of colored wool stretch refining and permanency shaping. The method comprises the steps that common wool is dyed, backwashed and dried by selecting different dyes and using a traditional method according to needs; the fineness of the colored wool after drying is 14.5-27.5 mu m; and carding, pretreatment, twisting, stretch refining, shaping, untwisting, oxidation, washing, drying and winding are carried out on wool bars so as to obtain the colored wool with the fineness of 12.7-22.7 mu m and the permanency shaping. The method is simple and rapid in process and high in production efficiency; the obtained wool subjected to the stretch refining has silk-like gloss and handfeel; the colors of various wool subjected to stretch refining are brighter than the colors of the common wool; the fineness, the disperse effect and the short wool rate of the colored wool are equivalent of those of the common wool with the same fineness; and the fiber strength of the colored wool is improved by 20% compared with the common 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 colored wool. Background technique [0002] In recent years, high-count and thin textile and garment products have become more and more popular among consumers, but so far most of the raw materials used in light and thin wool fabrics are fine wool in a natural state. These wools are expensive and have limited production. Especially cashmere fiber, not only the fiber itself is very precious, but also only cashmere goats can grow cashmere, and cashmere goats have great damage to the ecological environment. People study the method of stretching to thin wool, but many fine wool products have the following disadvantages: first, the stretching of fine wool is not enough, and the difference between the core and surface fineness of the top is large, generally around 2um; Second, the set...

Problems solved by technology

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

People study the method of stretching to thin wool, but many fine wool products have the following disadvantages: first, the stretching of fine wool is not enough, and the difference between the core and surface fineness of the top is large, generally around 2um; Second, the setting effect of stretched wool is poor, the setting temperature is high (110°C-160°C), and the setting is often used twice, and the fineness of stretched wool is unstable; Third, the stretching process takes a long time, high temperature, and low production efficiency , the production cost is high, and the fine wool is more damaged, the handle is rough, and the luster is not strong

Fourth, the permanently set stretched thinned wool has poor level dyeing property and difficult dyeing, which limits the use of stretched thinned wool
