Shrinkproof treatment technology for cashmere

Abstract

The invention provides a shrinkproof treatment technology for cashmere. The technology comprises the steps of immersing cashmere fibers in warm water, dewatering the cashmere fibers, treating the cashmere fibers in a protease solution, then dewatering the fibers after the fibers are subjected to a water bath, treating the cashmere fibers through a peracetic acid solution, and finally treating the cashmere fibers through Na2SO3 reducing treatment liquid. The cashmere is treated by the combination of protease and peracetic acid, so that an extremely good shrinkproof effect can be achieved; a treated wool product is high in friction performance, stretching performance and shrinkproof performance; furthermore, balling of a cashmere fabric can be reduced, the cashmere fabric is endowed with machine-washable and shrinkproof properties, the performance of the cashmere fabric is enhanced, and thus requirements of customers can be met.

Description

technical field [0001] The invention relates to an anti-shrinkage treatment process for cashmere. Background technique [0002] Cashmere is a high-quality textile raw material and has the reputation of "soft gold". Cashmere products (such as cashmere sweaters) processed with it have the characteristics of smooth, light, warm and elegant. Because the surface of cashmere fibers has a scale layer structure, the fibers have curling characteristics. During the washing process of cashmere products, the cashmere fiber aggregates are oriented and arranged under the action of damp heat and chemical reagents and repeated continuous and irregular mechanical forces. The scales will cause displacement between the fibers through friction, resulting in shrinkage, shrinkage of the fabric area, and unstable shape. This is the shrinkage of cashmere fibers. The shrinkage of cashmere makes pure cashmere fabrics that have not been treated with anti-shrinkage shrinkage, resulting in poor fabric...

AI Technical Summary

Problems solved by technology

At present, in the actual production of the factory, the chlorination method, the oxidant plus resin method, etc. are mainly used for the anti-shrinkage treatment of plush. Although it has a certain effect, it produces a large amount of organic halogen AOX, which seriously pollutes the environment.
