摘要: γ-(β-Hydroxy-γ-5,5-dimethylhydatoin)-propyltriethoxysilane, a N-halamine precursor, was synthesized with 3-aminopropyltriethoxysilane and 3-glycidyl-5,5-dimethylhydantoin. The precursor tethered to the cotton fabric through ether linkages. treated fabrics can be rendered excellent antimicrobial activity bleaching process. It inactivate 100% of Staphylococcus aureus Escherichia coli O157:H7 contact time 10 min 30 min, respectively. Over 30% chlorine could regained after equivalent 50 machine washes rechlorination. coatings resulted in significant increase hydrophobicity samples. In addition, wrinkle recovery angle increased some degree. Copyright © 2014 John Wiley & Sons, Ltd.
