Abstract
The article presents research on the development of a biocidal preparation for the appret of cotton textile materials. The appret developed by the authors on the basis of salicylic acid and liquid glass provides high rates of biostability of cotton fabric, does not reduce quality indicators and meets the environmental requirements for appret compositions. The coefficient of resistance to microbiological destruction in cotton textile materials treated with a biocidal preparation in all cases was above 80%. The work also assessed the safety and quality of cotton materials treated with a new biocide.
