Polyvinyl pyridine metal complex as permanent antimicrobial finishing for viscose fabric.
Viscose fabrics were treated with polyvinyl pyridine (PVP) using padding technique, followed by oxidation with hydrogen peroxide or peracetic acid, which was prepared by the reaction of tetra acetyl ethylene diamine (TAED) with hydrogen peroxide. Peracetic acid gives higher oxidation of PVP than hydrogen peroxide. FTIR study proved the formation of N-oxide as a result of oxidation. Incorporation of copper and silver ion onto oxidized PVP was also proved by FTIR. The antimicrobial study emphasise that Cu/oxidized PVP and Ag/oxidized PVP have retarded the growth of bacteria significantly, and Ag/oxidized PVP has a far better biocidal activity. The antibacterial activity of both metal ions survived after washing 10 times.
