Problems solved by technology

Silk is easy to attach and breed various bacteria and molds, which will cause peculiar smell and stains and reduce the strength of silk fabrics, causing great economic losses and even affecting the wearer's health
[0003] Due to the difficulty in the treatment of biological fibers, there are more antibacterial researches on natural plant fibers in my country, but less research on biological fibers.
The antibacterial treatment method of natural silk fabrics mostly adopts physical dipping method, and the antibacterial agent uses inorganic metal ions, so the antibacterial silk produced in this way is not resistant to washing, and the antibacterial persistence is relatively poor.
[0004] With people's repeated wearing and washing, the antibacterial property is greatly reduced, which affects the health of the body, which seriously restricts the development of natural silk fabric antibacterial treatment technology

Abstract

The invention relates to an antibacterial treatment method for a natural silk fabric surface. The method includes: adopting silicon dioxide loaded nano-silver as an antibacterial agent, leaving it and a coupling agent to undergo a high temperature reaction, and then letting the reaction product react with a silk fabric. The method employs a chemical grafting method to link the antibacterial agent with a silk fiber surface by the coupling agent so as to form a washable antibacterial functional layer. SEM analysis show that the antibacterial layer on the natural silk fabric surface is uniform, and the grafting effect is good.

Description

technical field [0001] The invention relates to an antibacterial treatment method for the surface of natural silk fabrics, in particular to a method for treating the surface of natural silk fiber fabrics with nano-silver antibacterial agent loaded on silicon dioxide. Background technique [0002] Silk fiber is the earliest animal fiber used by human beings. It is one of the lightest, softest and thinnest natural fibers. It is widely used in various industries and is a green product respected by the world. The structure of silk is very similar to human skin, so it is comfortable to wear. Silk fiber is a protein fiber, composed of 18 kinds of amino acids, containing about 97% pure protein. Silk is easy to attach and breed various bacteria and molds, which will cause peculiar smell, stains and strength reduction of silk fabrics, cause great economic losses, and even affect the wearer's health. [0003] Due to the difficulty in the treatment of biological fibers, there are mor...
