INVESTIGATION OF MECHANICAL PROPERTIES OF COTTON-POLYESTER FABRICS WITH BIOCIDAL TREATMENT

Abstract

This article is devoted to the study of some aspects of increasing the biostability of cellulose-containing textile materials with new ecological biocidal products. This paper considers the study of the possibility of application for antimicrobial treatment of clothing cellulose-containing textile materials, new biocidal products of thiosulfonate structure and evaluation of changes in some of their mechanical properties. The influence of biocidal treatment on the rupture characteristics of tissues of different fibrous composition has been studied. New biocidal preparations of thiosulfonate structure of domestic production are used for biocidal treatment, which are synthetic analogues of natural phytoncides – garlic, onion and certain types of cabbage – ethylthiosulfanilate (ETS), methylthiosulfanilate (MTS) and allylthiosulfanilate (AТS). The aim of the article is to study the effect of new biocidal drugs of thiosulfonate structure on the change of the main mechanical properties that determine wear resistance. The efficiency and expediency of the use of these biocides are shown. As a result of the analysis of the received experimental data it is established that new biocidal drugs ETS, ATS, MTS not only protect fabrics from undesirable microbiological destructions, but also do not lead to deterioration of physical and mechanical properties of investigated fabrics. As a result of treatment with biocidal products of thiosulfonate structure of pure cotton and cotton-polyester fabrics for special purpose clothing, there is no significant reduction in the breaking load. This is due to the fact that when treated with the studied biocidal products as a result of modification there is no increase in the mutual mobility of cellulose macromolecules, so the possibility of load redistribution within the fiber and tensile strength fall on more structural elements.
