Abstract:
In order to fabricate antibacterial cotton fabric with excellent antibacterial property and laundering durability, amino functional silver nanoparticles (Ag NPs) were prepared by one-step reaction with amino-terminated hyperbranched polymer (HBP-NH(2)) and grafted on the oxidized cotton fabric subsequently. The synthesized amino functional Ag NPs and Ag NPs grafted oxidized cotton fabric (Ag-GOCF) were characterized which indicated that the average size of Ag NPs was 10.8 nm with narrow size distribution and the Ag NPs have been grafted on the cotton fabric. 99.43% and 99.45% bacterial reduction rates were obtained for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) respectively in case the cotton fabric was treated with 10 mg/L Ag NPs solution to produce Ag-GOCF with 149.88 mg/kg Ag content. After 50 washing cycles, the Ag content of this Ag-GOCF was maintained at 116.08 mg/kg with its antibacterial activity at over 96% reduction level.
