ДОСЛІДЖЕННЯ СВІТЛОСТІЙКОСТІ ПОФАРБУВАНЬ БАВОВНЯНОГО ТРИКОТАЖУ, ОБРОБЛЕНОГО НОВИМИ ТІОСУЛЬФОНАТНИМИ ПРЕПАРАТАМИ

Abstract

Purpose. The purpose of this work is to introduce the new types of antimicrobial preparations to the cellulose production to provide at the same time bio-resistance, weather resistance and environmental safety to cotton, polyester, multi-component materials. The most demanded creation is producing similar materials for the products of linen assortment, which are directly in contact with the skin, safe for human health and environment. Products from such materials can be used both at home and in medical institutions, in the food industry, in trains of long-distance trafficking, in the army, etc. A lot of attention all over the world is paid for the development of various methods for obtaining and studying the properties of materials with antiseptic attributes. However, despite the large amount of work in this area, many issues are still far from their solution. In particular, the actual task is to create environmentally friendly textile materials and knitted cloths with antimicrobial properties, which are stored in wet treatments, washing, light exposure, that is necessary in using underwear in real conditions.\xa0 The problems associated with reducing the cost to obtain such materials are equally important. Therefore, the purpose of our research is to analyze the light-fastness of paints and the substrate of linen cotton knitted fabrics treated with antimicrobial thiosulfonate preparations of ETS, MTS and ATS. \nMethod. The methods provided in applicable state standards that determine the lightness of colors (color tone, lightness, saturation, overall color contrast) and the breaking characteristics of the cotton linen fabrics were used in the studies. \nResults. The possibility and feasibility of using thiosulonate preparations including ETS, MTS and ATS in the domestic textile and knitwear production for antimicrobial treatment of cotton linen knitted cloths of the summer range for the purpose of their effective protection against biodestruction by cellulose-destroying pathogenic and soil microorganisms are substantiated. In the process of antimicrobial treatment of the studied cotton knitted fabrics by ETS, MTS and ATS preparations, no noticeable changes in their mechanical (breaking strength) properties are observed, which may worsen the wear resistance and hygienic performance of these fabrics during the operation of products from them.\xa0No negative influence of treatment with ETS, MTS and ATS preparations on the change of color characteristics (lightness, saturation, color tone and general color contrast) and light stability of coloring of studied knitted fabrics by cubic dyes was found. The main advantage of thiosulfonate treatments is that their use guarantees simultaneous achievement on knitted cotton linen and clothing cloths of high atmospheric resistance without degradation of their mechanical properties.\xa0Scientific novelty. As a result of the research, thiosulfonate antimicrobial preparations including ETS, MTS and ATS are found to able to effectively protect the cotton linen knitted linen of the summer range from prolonged exposure to solar radiation. \nPractical significance. The thiosulfonate preparations chosen by us, such as ETS, MTS and ATS, are revealed to suitable not only for effective protection against microbiological destruction, but also from the long-lasting effect of light clothing of cotton knitted linen of summer assortment (working clothes, sportswear).
