RESEARCH AND DEVELOPMENT OF ANTIMICROBIAL COMPOSITIONS FOR WOOL MATERIALS

Abstract

The article analyzes the existing methods of imparting antimicrobial properties to textile materials and assesses their effectiveness. The purposeof the work. Production of woolen materials with antimicrobial properties. Methodology.The work uses scientific, logical, objective research methods. Results and discussion.Technologies for obtaining antimicrobial woolen materials have been developed. Studies have been conducted on the influence of the proposed compositions on the coefficient of resistance to microbiological destruction of woolen materials. It was found that the antimicrobial effect in all compositions is achieved at a minimumconcentration of polyhexamethyleneguanidine hydrochloride, more than 80%. Studies on the resistance of antimicrobial properties of modified samples to repeated washings have shown that the coefficient of resistance to microbiological destruction is reduced by 10-16%. It follows that the proposed formulations have a residual antimicrobial effect. The influence of the developed compositions on the physico-chemical and physico-mechanical properties of textile materials has been studied. The properties and structure of the objects of research are studied, and the mechanism of interaction of the components used is investigated. Parameters of application and heat treatment, the optimal modes of the technological process of finishing textile materials have been established. Conclusions.The developed technology provides antimicrobial activity of textile material while maintaining the hygienic and operational properties of woolen materials. Studies have shown that modified woolen textile materials acquire antimicrobial properties, and are not destroyed by microorganisms under operating conditions, and the quality indicators of textile materials do not deteriorate after processing.
