ВЛИЯНИЕ НАНОКОМПОЗИЦИИ СЕРЕБРА И КАРБОКСИМЕТИЛКРАХМАЛА НА ЦВЕТ И АНТИБАКТЕРИАЛЬНЫЕ ХАРАКТЕРИСТИКИ ОКРАШЕННЫХ РЕАКТИВНЫМИ КРАСИТЕЛЯМИ ХЛОПЧАТОБУМАЖНЫХ ТРИКОТАЖНЫХ ТКАНЕЙ

Abstract

This study discusses the change in color and antibacterial activity of cotton knitted materials dyed with reactive dyes in orange (Orange 2R) and purple (Rapeko red L) colors after treatment with a nanocomposition of silver and carboxymethyl starch of various concentrations. Antibacterial activity was tested against gram-negative E. coli bacteria and gram-positive S. aureus bacteria. Dyed knitted fabrics treated with AdKMC nanocomposition showed excellent antibacterial properties regardless of the concentration of nanosilver. The color change of knitted fabrics depends on the content of Ag nanoparticles. The stability of these nanocomposite knitted materials has been tested for wet treatments. Knitted fabrics demonstrate excellent antibacterial properties and excellent resistance to washing. After withstanding 10 washing cycles, the resulting fabrics still showed excellent bacterial resistance against Bacillus subtilis and Staphylococcus aureus. Thus, this method for the preparation of antibacterial dyed cotton knitted materials shows great potential applications in socks and medical textiles.
