The stabilization of nano silver on polyester filament for a machine-made carpet

Abstract

Nowadays, polyester filament yarns with permanent anti-bacterial characteristics are known as an innovative yarn in the textile industry for machine-made carpets and garments. Different methods, such as chemical modification, entrapment and encapsulation, have been applied to stabilize the silver nanoparticles on polyester filament yarn for use in machine-made carpets. In this article we modified the nano-silver particles by a chemical reaction in order to produce a polyester filament yarn with permanent anti-bacterial characteristics using a spraying method. The anti-bacterial tests were carried out on the nano-silver-coated machine-made carpet according to ATCC 27853, 25923 and 25922 some 72 h before and after the washing process. The results showed that the nano-silver-coated polyester machine-made carpet has a permanent anti-bacterial characteristic.

Razli~ne metode, kot so kemijska obdelava, ujetje in enkapsulacija, so bile uporabljene za stabilizacijo nanodelcev srebra na vlaknih poliestrske preje za strojno izdelavo preprog.^lanek predstavlja modifikacijo nanodelcev srebra s kemijsko reakcijo z napr{evanjem za izdelavo vlakna poliestrske preje s stalno protibakterijsko odpornostjo. Protibakterijski preizkusi so bili opravljeni na strojno izdelani preprogi, prekriti z nanodelci, skladno z ATCC 27853, 25923 in 25922, 72 h pred pranjem in po njem. Rezultati so pokazali, da ima strojno izdelana preproga iz poliestra, prekritega z nanodelci srebra, trajno protibakterijsko odpornost.

Mycosynthesis of silver nanoparticles using Aspergillus caespitosus: Characterization, antimicrobial activities, cytotoxicity, and their performance as an antimicrobial agent for textile materials

“…Additionally, the environmental conditions on textiles are favorable for microbial adherence and growth. [ 16 ] The spreading the microorganisms from fabric surfaces to the human skin is a major health concern. Therefore, antimicrobial textile finishing is one of the significant research areas and the fastest growing sector in the textile industry.…”
