Abstract

The invention relates to a preparation method of antibacterial flame-retardant silk fabric, belonging to the field of spinning. Aiming at the problems of bad antibacterial property, unsatisfactory flame-retardant effect and low durability of existing silk fabric, the preparation method provided by the invention comprises the following steps: extracting natural antibacterial substances and lipid substances in honeysuckle and herba andrographitis to obtain antibacterial liquid; with sodium silicate as a flame-retardant substrate and in a bromoacetic acid environment, enabling the sodium silicate to react with carbamide peroxide and phosphoric acid under the catalysis of zinc chloride to obtain a composite flame retardant; mixing the composite flame retardant and adding hydrogen peroxide for blanching to obtain treatment liquid; and soaking silk fabric in the treatment liquid, wherein due to the specific amino acid active group on the surface of the silk fabric and through the excitation of X-ray irradiation, the silk fabric reacts to be combined with the hydroxyl and carboxyl substances in the composite flame retardant and antibacterial substances to obtain antibacterial flame-retardant silk fabric. The silk fabric prepared by the method has the advantages of good flame retardance, durability, strong antibacterial ability and environment-friendly materials.

Description

technical field [0001] The invention relates to a method for preparing an antibacterial flame-retardant silk fabric, which belongs to the field of textiles. Background technique [0002] Silk fabrics refer to fabrics whose raw materials are woven from silk. There are two kinds of weaving methods: knitting and weaving. In our daily life, textile fabrics are widely distributed in various fields, such as clothes, curtains, and car decoration fabrics. Data shows that the number of fires caused by textiles accounts for about 50% of the total number of fires in the year, and most of the textiles are in direct contact with the human body. The burning of textiles can cause burns to human skin. The existing antibacterial silk production method Some use TiO2 to improve the antibacterial ability of silk fabrics, soak them in traditional Chinese medicine liquid and then dry them, and add antibacterial agents to silk fabrics, but the existing silk fabrics do not have good antibacterial ...
