Problems solved by technology

But there are two fatal shortcomings: a. The scales on the surface of the wool fiber are destroyed and stripped by chlorination, which seriously damages the wool structure, which also changes the appearance, softness and warmth of the fabric, and reduces the wear resistance. , feels a bit rough
The mechanism of applying protease to wool for anti-felting finishing is that the cuticle of wool fiber is degraded under the action of enzymes, especially the disulfide bonds are broken into hydrophilic groups, which has an important impact on the softening of scales, but the strength drops significantly and the cost is high , not widely used
[0015] To sum up, the most commonly used and effective shrink-proof method for wool is still the chlorination method, but due to the increasingly stringent environmental protection requirements, although the shrink-proof effect of the wool treated with chlorination is better, due to the introduction of Chlorine-containing oxides are not conducive to the production of workers, and the wool fabrics produced cannot meet the high environmental protection requirements. Therefore, the replacement of chlorine-containing anti-shrinkage agents is a crucial issue at present.

Abstract

The invention relates to a non-chlorine shrink-proof method of wool fabric. The non-chlorine shrink-proof method comprises an oxidation process and a reduction process, wherein the oxidation process is proceeded in a solution which contains a non-chlorine oxidizing agent; the reduction process is proceeded in a solution which contains a reducing agent. According to the non-chlorine shrink-proof method of the wool fabric, disclosed by the invention, the fabric obtained through the non-chlorine shrink-proof method is environmental-friendly and is easy to care, and the wool shrinkage of the processed wool fabric can be controlled within 8 percent.

Description

technical field [0001] The invention belongs to the field of wool fabric care, in particular to a non-chlorine anti-shrinkage method for wool fabric. Background technique [0002] So far, the commonly used wool shrink-proof methods are as follows: [0003] (1) Low temperature plasma [0004] Glow discharge is carried out in various high-frequency oscillating power magnetic field induction methods, and ionization produces high-energy particles mainly ions. These high-energy particles can promote the etching, exchange, grafting and copolymerization reactions of the thin layer on the fiber surface. After the wool fiber surface is etched by plasma, it becomes uneven, the friction coefficient of the fiber increases, and the directional friction effect can be changed, and the cohesion of the fiber is improved, thereby achieving the effect of shrinkage prevention. This method has less damage to fibers, fast processing speed, and environmental protection, but its large-scale appl...
