Abstract
An advanced method with an initiator pretreatment was developed for the coating of nylon/cotton fabrics with the hydantoin‐containing monomer 3‐allyl‐5,5‐dimethylhydantoin and two water‐soluble crosslinkers N,N′‐methylene bisacrylamide and poly(ethylene glycol) 200 diacrylate. The formulations were applied to textiles by either batch coating or dip coating. In the dip‐coating process, the influence of individual parameters on the fabric modification was investigated and evaluated. After treatment with chlorine, the hydantoin structure was transformed into antimicrobial active N‐halamines. The modified fabrics exhibited potent antibacterial properties against Staphylococcus aureus and Escherichia coli. Our method, based on an initiator pretreatment and water‐soluble crosslinkers, outperformed current technologies in the degree of fabric modification. © 2010 Wiley Periodicals, Inc.
