Embodiment 1

[0022] Dissolve chitosan in 1% acetic acid solution, heat and stir after the dissolution is complete, add 2% hydrogen peroxide solution, until the reaction is complete, filter and wash, dissolve in citric acid solution to obtain a particle size of 100nm chitosan solution;

[0023] Add 0.2 g of sodium phosphate to the attapulgite solution with a mass fraction of 1%, to promote the dispersion of attapulgite, adjust the pH value to 6, and ultrasonically stir until the attapulgite particles are uniformly dispersed to obtain a nano attapulgite particle solution with a particle size of 100 nm. The chitosan solution and the attapulgite nano particle solution are uniformly mixed with a volume ratio of 1:1 to obtain a mixed solution;

[0024] Soak the soaked silk fabric in a mixed solution at 30°C for 20 minutes, bath ratio 1:40, take out the excess rate of 100%, dry at 60°C, wash with water, and dry to obtain antiseptic and antibacterial silk fabric. Through the test of Escherichia c...

Abstract

The invention discloses a preservative and antimicrobial finishing method of silk fabrics. The preservative and antimicrobial finishing method is used for improving the preservative and antimicrobial properties of the silk fabrics, wherein chitosan and nanoscale attapulgite clay particles are used as main raw materials. The preservative and antimicrobial finishing method comprises the following steps: evenly mixing a chitosan solution obtained by degradation under an acidic condition with a nanoscale attapulgite clay particle solution to form a mixed solution, putting the silk fabrics in the mixed solution for padding, drying and washing with water, and then drying to obtain preservative and antimicrobial silk fabrics. The preservative and antimicrobial finishing method of the silk fabrics has the advantages that the preservative and antimicrobial properties of the silk fabrics are improved by the combining of the chitosan and the nanoscale attapulgite clay particles, the treated silk fabrics are free from toxics, safe, environmentally friendly, high in preservative and antimicrobial capacity and lasting in preservative and antimicrobial properties, and consequently, the silk fabrics have a relatively high health care function.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, in particular to an antiseptic and antibacterial finishing method for silk fabrics. Background technique: [0002] Silk fabric has excellent wearing properties, and is especially suitable for making underwear boxes and baby clothes that have high requirements for antiseptic and antibacterial properties. However, silk fabric itself is a protein fiber and is a good food for mold and bacteria. In order to improve the antiseptic and antibacterial wearability of silk fabrics, the technology is divided into two types: one is to prepare antiseptic and antibacterial fibers and then weave them into fabrics; Antibacterial agent is one of the main directions to improve the antiseptic and antibacterial properties of silk fabrics. [0003] Antiseptic and antibacterial agents for textiles mainly include quaternary ammonium salts, organosilicon quaternary ammonium salts, chitin, inorganic salts and ...
