Cotton Fabric Finished by WPU/LPAA Modified Nano-ZnO for Antibacterial Applications

Abstract:

An antibacterial agent (ZPU) was prepared by surface modification of nanoZnO with aliphatic aqueous polyurethane (WPU) and polyacrylates sodium of lower molecular weight (LPAA). Then two kinds of cotton fabrics were dipped in ZPU and finally finished by paking-baking process. ZPU and the finished cotton fabrics were characterized by SEM, TEM and DLS. The antimicrobial properties of the cotton fabrics were investigated. The results indicated that ZnO retained nanosize with little aggregation on the fabric surface. The finished cotton fabrics showed obviously antibacterial activity against S. aureus and E. coli with the 24 h antibacterial rate of 99%.
