Мартиросян І. Formation of quality and safety of textile products with biocidal processing.

Object of research - cellulose-containing textile materials treated with biocidal products of thiosulfonate structure. The purpose of the dissertation research is to increase the wear resistance and biosafety of cellulose-containing textile products by treating them with biocidal drugs of thiosulfonate structure, which will provide stable antimicrobial protection in special working conditions. Research methods - used standard research methods for textile products, including methods of instrumental and visual colorimetry, atomic absorption spectrometry. Mathematical and statistical methods of data processing using computer applications are used. The own technique of definition of biostability of text products is developed. Studies have been conducted in both laboratory and real operating conditions. The expediency of using biocidal products of thiosulfonate structure to give antimicrobial properties to textile materials and products is substantiated and experimentally confirmed. For the first time, the use of new biocides has been proposed - ethylthiosulfanilate (ETS), methylthiosulfanilate (MTS) and allylthiosulfanilate (ATS) to provide textile materials and products with antimicrobial properties; the influence of BPTS on the biostability of cellulose-containing textile materials based on them for protection against fiber-destroying microorganisms, molds and soil marine microflora is theoretically substantiated; the regularities and mechanisms of interaction of the fibrous composition of the substrate, the concentration of the biocide and the physiological group and the type of microflora for the formation of a rational antimicrobial effect are determined. The scientifically substantiated resource-saving method of obtaining safe textile products with high long-acting antimicrobial properties is proposed. A new assortment variety of textile products with special purpose antimicrobial properties has been introduced. The research results were implemented in the production conditions of Novolog LLP (Act on production tests dated 06.11. 2018); LLP "OLIS" (Act on implementation and production tests from 24.02.20); LLP «Teodora Sewing Production» (Act on production tests dated 20.02.20) and Khimtex State Enterprise (Act on production tests dated 29.12.19), industrial testing of textile materials processing in the production conditions of PJSC «ChShK» was carried out. The research results were implemented in the educational process of the National University "Lviv Polytechnic" (Acts of implementation from 28.05.20). Technical solutions are protected by two patents of Ukraine: a utility model and an invention.
