Antibacterial finishing method of silk fabric

Abstract

The invention discloses an antibacterial finishing method for silk fabrics. The method comprises the following steps: first adding water to the finishing agent to prepare an impregnating solution, then putting the fabric into the impregnating solution for padding, with a residual rate of 70-80%, and finally washing with water for 2 -3 times, it can be dehydrated and dried; the finishing agent is composed of the following components in parts by weight: 10-15 parts of polyoxyethylene ether, 3-8 parts of sodium polystyrene sulfonate, 2-methyl-4 - 15-20 parts of isothiazolin-3-one, 1-3 parts of oleoyl amino acid sodium, 3-6 parts of benzyltrimethylammonium chloride, 2-6 parts of sodium xylenesulfonate, 2-6 parts of starch ether 10-20 parts of propylene glycol, 3-6 parts of chitosan, 5-8 parts of isooctyl palmitate, 1-6 parts of acrylamide, 5-8 parts of vinyltrimethoxysilane, 2-7 parts of borax and 55-65 parts of deionized water. The silk fabric finished by the invention has good antibacterial performance, especially high inhibition rate to Escherichia coli and Staphylococcus aureus, can reduce the probability of people getting sick due to microorganisms attached to the fabric, and meet people's living needs.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an antibacterial finishing method for silk fabrics. Background technique [0002] Silk fabrics are made of silk or synthetic fibers, rayon, short silk, etc.; the general term for fabrics that are purely woven or interwoven with silk or rayon. After years of hard work, China has won the dominant position in the world silk market. The silk industry has become the country's pillar industry for foreign exchange, and a relatively complete silk industry system has been established. Silk products have been sold in more than 100 countries and regions around the world. [0003] Real silk is composed of protein fibers, which has excellent biocompatibility with the human body. In addition, its surface is smooth, and its frictional stimulation coefficient to the human body is the lowest among all kinds of fibers, only 7.4%. Good moisture absorption and dehumidification. Silk p...

In addition, bacteria also decompose human secretions and produce odorous substances such as ammonia, resulting in dirty body odor, leading to the spread or infection of skin diseases and affecting human health

Although the antibacterial finishing used on fabrics can reduce the bacteria on the surface of the fabric, it has poor washability and short antibacterial time. Some antibacterial finishing agents are irritating to the skin and have an unpleasant smell.
