Abstract

The invention provides a method for preparing cuprous oxide antibacterial textiles. The method first uses low-temperature plasma to pretreat cellulose fiber fabrics, introduces amino groups on the surface of the fabrics, and simultaneously etches the surface of the cellulose fiber fabrics; Covering silk peptide solution; then padding copper acetate solution, using copper ions and ‑COOH and ‑NH on silk peptide molecules 2 Coordination effect reduces the water solubility of silk peptide, improves the binding fastness of silk peptide, copper ions and textiles; and then forms cuprous oxide in situ on textiles to obtain antibacterial textiles. The obtained fabric not only has good antibacterial property, but also is washable.

Description

Technical field [0001] The present invention belongs to the field of textile technology, and more particularly to the preparation method of oxide antibacterial textile. Background technique [0002] With the improvement of living standards, people's health awareness is increasing. Porous textile fibers are easily absorbed in human sweat gland, at a suitable temperature, under humidity, microbes are extremely susceptible to grow, reproduction. The presence of microorganisms on textiles not only produces molds, but also hazards the health of the clothing. Therefore, it is necessary to antibacterial finishing for the fabric. [0003] Antibacterial finishing agent can be divided into three major categories: inorganic antibacterial finishing agents, organic antibacterial finishing agents and natural antibacterial finishing agents. Inorganic antibacterial finishing agents have broad-spectrum antibacterial and strong bactericidal capabilities. Studies have shown that nano-oxide copper c...
