Abstract

The surface of the polyester nonwoven fabric was covered with a layer of silver and copper-based nanoparticles obtained from their salts and reduced using tannic acid. Polyester nonwoven MILIFE® without surface modification was used as a carrier of the metallic layer. The repetitive technological steps of preparing the conductive layer led to an increase of color intensity of fabric with bronzing effect, which also manifested in their decreased electric resistance. Simultaneously, all the samples were tested for resistance to selected G+ and G- bacteria.
