Influence of antimicrobal treatment on change of hygroscopic properties and permeability of knitted clothes

Purpose. The purpose of this work is to study the hygroscopic properties and permeability of knitted fabrics after treatment by biocidal substances with thiosulfonate structure. The development of different methods for obtaining and studying the properties of materials with antimicrobial properties has received considerable worldwide attention. However, despite the large amount of work in this area, many questions need to be solved. In particular, the urgent task is to create environmentally friendly textile materials and knitted fabrics with antimicrobial properties, which are stored during wet treatments. Methods. The methods provided by current state standards that allow determining the hygroscopicity, capillarity and water resistance of the studied cotton knitted fabrics were used in the research. Results. Possibility and reasonable expediency of using in domestic textile and knitwear production of thiosulfonate processing preparations for the antimicrobial treatment of cotton knitted fabrics with the purpose of their effective protection against microbiological destruction was studied. In the process of antimicrobial treatment of the studied cotton knitted cloths with ethyl, methyl and allyl biocides no noticeable changes in their hygroscopic properties, which can impair the durability and hygiene of these cloths during their operation was determined. Scientific novelty. As a result of the research, it was found that thiosulfonate antimicrobials ETS, MTS and ATS are not only able to protect effectively the cotton knitted fabric led biodegradation, but also improve the hygienic properties. Practical importance. It is established that antimicrobial treatment with thiosulfonate drugs does not lead to a deterioration of the adsorption properties of knitted fabrics, but rather leads to an increasing of such indicators as hygroscopicity, capillarity, air permeability and others
