Problems solved by technology

[0003] At present, great progress has been made in the research of wool fabrics, such as the application of antibacterial agents such as heavy metal particles silver or heavy metal complexes, chitin, biological lysozyme, and cationic quaternary ammonium salts for antibacterial finishing of wool, but due to the special structure of wool itself And its chemical composition, usually wool textiles without pretreatment can not directly react with the finishing agent with antibacterial activity
Because of this technical difficulty, antibacterial wool textiles have not been commercialized on a large scale

Abstract

The invention discloses an antibacterial anti-shrinkage finishing process of a wool fabric. The process comprises the steps of pretreatment, antibacterial finishing, anti-shrinkage finishing and the like. (1) According to the finishing process of the invention, an immersion treatment way is mainly used, an antibacterial anti-shrinkage finishing solution can be easily arranged on the surface of thewool fabric by virtue of a series of pretreatment steps; and (2) the wool fabric after being finished by the finishing process of the invention has good antibacterial and anti-shrinkage performance,and the antibacterial durability and size stability of the fabric after being repeatedly washed are relatively good.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a functional wool fabric, in particular to an antibacterial and shrink-proof finishing process of the wool fabric. Background technique [0002] In a suitable temperature and humidity environment, natural fibers, especially protein fibers, become a good medium for microbial growth. The massive growth of microorganisms in textiles can cause textiles to degrade, produce spots, bad smells, etc. Antibacterial finishing of textiles is one of the ideal methods to solve these problems. Antimicrobial finishes can kill bacteria or inhibit their growth. [0003] At present, great progress has been made in the research of wool fabrics, such as the application of antibacterial agents such as heavy metal particulate silver or heavy metal complexes, chitin, biological lysozyme, and cationic quaternary ammonium salts for antibacterial finishing of wool, but due to the special structure of wool ...
