Abstract
This paper presents the improvement of the antimicrobial character of woven fabrics based on cotton. The woven fabrics were cleaned in oxygen plasma and treated by padding with silver chloride and titanium dioxide particles. The existence of silver and titanium on woven fabrics was evidenced by electronic microscope images (SEM, EDAX) and by flame atomic absorption spectrophotometry. The antimicrobial tests were performed with two fungi: Candida albicans and Trichophyton interdigitale. The obtained antimicrobial effect was considerably higher compared to the raw fabrics. Treatment of dyed fabrics with a colloidal solution based on silver chloride and titanium dioxide particles does not considerably influence colour resistance of dyes.
Highlights
Cotton is a common material for the production of textiles for sports, leisure, or medical uses
A microbial reduction of 49.81% was noticed for the Ibp fabric, possibly due to the formation of reactive chemical species which lead to chemical reactivity phenomena with the biological material
After treating types of fabrics (type I) and type II white/not dyed fabrics with the silver ion-containing solution, the following behaviour is highlighted in both cases: (1) DL∗ values are negative, which means that samples treated with AgCl and sTaimOp2 lesso;lu(t2i)onvaalureesdoarbktaeirnethdanforthDe Cc∗orareresppoonsdiitnivge,cownhtircohl means that samples treated with AgCl and TiO2 solution are more saturated than corresponding control samples; (3) as far as values obtained for DH∗ are concerned, for antimicrobially treated 100% cotton samples, type I and type
Summary
Cotton is a common material for the production of textiles for sports, leisure, or medical uses. Fluffy staple fiber that grows in a boll, or protective capsule, around the seeds of cotton plants of the genus Gossypium. The fiber is almost pure cellulose (Scheme 1). The cotton bolls will tend to increase the dispersion of the seeds. The chemical composition of cotton is as follows: cellulose 91.00%, water 7.85%, protoplasm, pectins 0.55%, waxes, fatty substances 0.40%, and mineral salts 0.20% [1]. The ability of cotton fibers to absorb large amounts of moisture makes them more prone to microbial attack under certain conditions of humidity and temperature. Cotton fibers are treated with numerous chemicals to get better antibacterial cotton textiles
