Abstract

The invention provides a preparation method of cuprous oxide antibacterial textile. The preparation method includes: pretreating cellulose fiber fabric with a low-temperature plasma, introducing an amino group to the surface of the fabric, and meanwhile, etching the surface of the cellulose fiber fabric; coating with a silk peptide solution; soaking and rolling with a copper acetate solution, reducing the water solubility of silk peptides and improving the binding fastness of silk peptides and copper ions to the textile by using -COOH and -HN2 coordination on copper ions and silk peptide molecules; performing in-situ formation of cuprous oxide on the textile to obtain the antibacterial textile. The textile is good in antibacterial resistance and resistant to washing.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for preparing cuprous oxide antibacterial textiles. Background technique [0002] With the improvement of living standards, people's health awareness is increasing day by day. Porous textile fibers can easily absorb human sweat glands, and microorganisms can easily grow and reproduce under appropriate temperature and humidity. The existence of microorganisms on textiles not only makes textiles mildew, but also endangers the health of users. Therefore, it is very necessary to carry out antibacterial finishing to fabrics. [0003] Antibacterial finishing agents can be divided into three categories: inorganic antibacterial finishing agents, organic antibacterial finishing agents and natural antibacterial finishing agents. Inorganic antibacterial finishing agent has broad-spectrum antibacterial and strong bactericidal ability. Studies have shown that nano-cuprous oxide ...
