“…To load silver nanoparticles on the surface of fibers, the fibers are usually exposed to a silver nanoparticle sol, resulting in random attachment of nanoparticles on the surface [17][18][19]. The problem in this case is the weak binding of nanoparticles on the surface, so that after a few times washing they are completely removed.…”

“…ion could be very active in reducing bacteria population on agar media [8]. Metal and metal oxide nanoparticles, such as silver and magnesium oxide, were also found to be effective against bacteria [9][10][11]. On the other hand, nanoparticles in liquid systems are known to suffer from the aggregation due to the presence of bacteria, hence leading to decrease in their biocidal activities [9].…”
We report the antibacterial efficacies of silver and/or silver chloride containing titania xerogels synthesized with modified single step sol-gel methods against Escherichia coli bacteria. As the silver loading in TiO 2 increases, the amount of the xerogel required to inhibit the growth of the bacteria decreases and also we found that pure TiO 2 was not bactericidal. Among modified single step sol-gel methods used in this study, the additional HCl treatment sol-gel route III was very effective to obtain only AgCl crystallites in TiO 2 . Based on viable cell count method, 0.125 g/L of 29%Ag/TiO 2 (made with HNO 3 solgel route I) was enough to inhibit the growth of E. coli whereas 0.6 g/L of 29%Ag/TiO 2 (made with the additional HCl treatment sol-gel route III) was required. However, antibacterial activity of 29%Ag/TiO 2 (made with HNO 3 sol-gel route I) after 6 usages was the same as 29%Ag/TiO 2 (made with the additional HCl treatment sol-gel route III).
“…Smart silver-enhanced fibers can be used to create odor-resistant undergarments, hats, gloves, socks, T-shirts, sweaters, carpets and more [100][101][102].…”
The present article reviews recent developments in different treatments that confer functional characteristics on wool and some synthetic fibers such as acrylic, polyamide and polyester of these functionalities mention is made of shrinkage-resistance, felt proofing, ant pilling, antimicrobial, surface properties (hydrophilic, soil -resistance, water and oil-repellency), self-cleaning, anti odor and flame retardant. The article also illustrates nanotechnology applications to improve and / or to induce some of these properties. Improvement of these properties can give the fibres an important position between the textile fibres which make them more convenient in different uses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
