THE INFLUENCE OF LOW-TEMPERATURE PLASMA ON PERMANENCE OF ANTIMICROBIAL NANO-FINISH

Abstract

This paper describes the effect of low-temperature plasma on increasing permanence of surface finish of textile materials using an antimicrobial nanosol. Selected textile materials (polyester and polyamide woven fabrics, polypropylene non-woven fabric) were pre-treated by surface activation with low-temperature plasma at atmospheric pressure and subsequently finished using an antimicrobial (AMB) nanosol with a concentration of 60 ppm Ag+, 120 ppm Ag+ in the application solution. The goal was to increase the permanence of AMB nano-coating of textiles after washing and drying. To verify the effect of low-temperature plasma on increasing the permanence of the nanolayer, washing and drying was performed in accordance with the STN EN ISO 6330 standard. To determine antibacterial activity and effectiveness of the nano-coated textile materials, a quantitative test method was used in accordance with the technical standard AATCC TM 100. Evaluation of the antibacterial activity of the textile materials was performed before washing and after 20 washing cycles.
