METHOD FOR MANUFACTURING ANTIBACTERIAL FABRIC WITH OIL-, WATER, AND DIRT-REPELLENT PROPERTIES Russian patent published in 2021 - IPC D03D15/00 

FIELD: textile industry.

SUBSTANCE: invention relates to the textile industry, it can be used in the manufacture of protective fabrics with antibacterial, water-, oil-, and dirt-repellent properties for sewing special clothing, clothing for doctors, school uniforms. The method includes weaving by interlacing the warp and weft of a mixed yarn based on cellulose-containing and synthetic fibers in the mass ratio (20-80):(80-20), respectively, or polyester yarns, preparatory processing and final finishing. The final finishing consists in impregnation with a composition containing, wt.%: 3.0-5.0 of water dispersion of a fluoropolymer based on perfluoroacrylate (5%), 0.1-0.3 of water dispersion of perfluorocarboxylic acid amides with a molecular weight of 1000-1200 (5%), 0.5-1.0 of preparation based on nanoscale silver particles, 0.02-0.04 of acetic acid and water up to 100, drying, heat treatment and sanforization of the fabric. v

EFFECT: improvement of the performance properties and preservation of the protective properties of the fabric after repeated washings.
