Problems solved by technology

Cashmere anti-shrinkage treatment processes the fiber, so that the fiber shrinkage uniformity obtained by this treatment is better, and the washing rate of the anti-shrinkage washed wool is high, but the scale layer of the fiber is destroyed by the anti-shrinkage treatment, which reduces the fineness of the fiber. The high degree of strength, elasticity and bending stiffness make the fiber more prone to hair particles in the subsequent processing of combing, which will increase the difficulty of spinning and other problems.
At present, the industrial application of chlorine oxidation process to process cashmere will produce a large amount of organic halides, which have toxicological properties, carcinogenicity, and non-biodegradability

Abstract

The invention discloses a cashmere yarn shrink-proof process. The cashmere yarn shrink-proof process comprises the following steps of pretreatment, potassium permanganate oxidation treatment, washing, reduction treatment, secondary washing, softening treatment, drying and plasma treatment. The shrink-proof process is easy to operate and high in security; the whole procedure is environment-friendly; prepared cashmere yarns are high in shrink-proofing performance and decoloration resistance.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to an anti-shrinkage process for cashmere yarns. Background technique [0002] Known as "soft gold", cashmere fiber is a natural fiber with a long history and one of the precious natural textile raw materials in the world. Its textile products are favored by people for their unique lightness, softness and slipperiness favorite. The pure cashmere products processed from cashmere are comfortable to wear, have strong thermal insulation, plump suede, soft handle, and soft luster. However, the typical scale structure of cashmere fiber makes it have special shrinkage. Appropriate milling can enhance the thermal insulation performance of the fabric and be full of elasticity. However, in the process of use, milling reflects its unfavorable side that cannot be ignored. Clothing will be felted due to milling during wearing and washing, making the fabric feel hard and rough, shrinking and...
