Abstract

The invention discloses an antibacterial peptide finishing process for a wool fabric, wherein the process comprises three steps of oxidation pretreatment of the wool fabric, treatment with an antibacterial peptide buffer solution and curing crosslinking treatment. Antibacterial peptides are defensive polypeptides having an effect of resisting exogenous pathogen pathogenicity and produced by a biological immune defensive system, and have broad-spectrum antibacterial activity and relative small molecular weight; through two finishing procedures, the wool fabric is finished and can be endowed with excellent antibacterial properties, the washing fastness of the wool fabric is effectively improved, and the wool fabric is safe to human health and also has a certain health-care function.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to an antibacterial peptide finishing process for wool fabrics. Background technique [0002] As a natural protein fiber, wool has many excellent properties that other fibers cannot match, such as: good elasticity, soft luster, strong hygroscopicity, not easy to stain, good warmth retention, etc., so it has always been favored by consumers. Under suitable temperature and humidity, natural fibers, especially wool fibers, can provide a good growth environment for microorganisms. Bacteria and microorganisms growing on textiles not only affect the physical properties of textiles, produce bad smells, stains, etc., but also cause skin allergies and other adverse symptoms more seriously. Antibacterial finishing can solve these problems. A range of antimicrobial finishing products has been launched on the market. Although some progress has been made in antibacterial research o...
