摘要：
An amino-terminated hyperbranched polymer (HBP-NH2) was grafted to cotton fabric by a reaction between the aldehyde groups of oxidized cotton fabric and the amino groups of the HBP-NH2 to provide cotton fabric with durable antimicrobial properties. The antimicrobial activities of the HBP-NH2 aqueous solutions and the HBP-NH2 grafted cotton fabrics were evaluated quantitatively against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The results indicated that the HBP-NH2 grafted cotton fabric showed 92% of bacterial reduction to S. aureus and 95% of bacterial reduction to E. coli, respectively. The antimicrobial activities of the HBP-NH2 grafted cotton fabrics were maintained at over 91% reduction level even after being exposed to 20 consecutive home laundering conditions. Several influence factors, which may affect the amount of HBP-NH2 grafted onto the cotton fabrics, were also discussed.
