Problems solved by technology

[0003] During the processing process, wool fabrics have to go through the steps of scouring, combing, dyeing, etc., and will be affected by processing temperature, pH, mechanical force and chemicals, which will cause damage to the chemical structure and physical and mechanical properties of the fiber. At the same time, due to Due to the nature of wool’s natural protein fiber, wool fabrics are prone to fluffing and pilling, and are not easy to care for. After wearing and washing, the surface of wool fabrics is more prone to fluffing and pilling.
Not only will it affect the hand quality of wool fabrics, but it will also cause irreparable quality problems
The existing processing method mainly reduces the directional friction by adding an oxidizing agent or a reducing agent. A kind of anti-pilling finishing process of wool fiber fabric disclosed in Chinese invention CN201210181666.2 improves the anti-pilling of wool fiber fabric to a certain extent property, but there is a large damage to the fiber, the overall effect is not very ideal, and the process parameters are slightly deviated. damage

Abstract

The invention relates to the technical field of textile industry development, and discloses a processing method for improving pilling resistance of a wool fabric. An anti-pilling finishing agent is prepared by a polymerization reaction; after finishing the wool fabric, a uniform breathable coating layer can be formed on the surface of a wool fiber, the relative breaking strength and the relative breaking elongation are improved to a certain extent, the wet mechanical performance is improved, the electrostatic phenomenon is significantly improved, both the static friction coefficient and the dynamic friction coefficient of the wool are substantially reduced, a fiber scale layer can be effectively fixed, and the stability of wool keratin is improved, so that the hair shaft can resist the erosion of external machinery, chemicals, etc., the wool gloss, the hand feeling and the comfort are maintained, the anti-pilling performance of the wool fabric is improved, and the wool fabric can be subjected to machine wash; and the process can well solve the problem of large fiber damages caused by the fact that the existing anti-pilling method destroys and removes the fiber scale layer by usingchemical reagents.

Description

technical field [0001] The invention belongs to the technical field of textile industry development, and in particular relates to a treatment method for improving the pilling resistance of wool fabrics. Background technique [0002] The main component of wool is keratin, which is composed of a variety of α-amino acid residues, which can be linked into long-chain helical molecules, which contain carboxyl groups, amine groups and hydroxyl groups, etc., forming salt bonds and hydrogen bonds etc. The long chains are linked by cross bonds formed by cystine disulfide bonds. The chemical structure described above determines the properties of wool. Wool fibers are soft and elastic, and can be used to make textiles such as woolen wool, woolen yarn, blankets, and felt. Wool textiles have the advantages of good elasticity, strong moisture absorption, good warmth retention, and good comfort. They are favored by consumers and become one of the high-quality natural fiber materials wide...
