Abstract

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