Antimicrobial Finishing of Cotton with Zinc Pyrithione

Abstract
Solutions of a zinc complex of pyrithione in aqueous polyethylenimine were applied to cotton fabric by a conventional pad-cure procedure. When the solutions also contained urea, pyrithione was bound in the fabric. Fabric treated by one process still completely inhibited growth of Staphylococcus aureus after fifty launderings. It also completely inhibited growth of Trichophyton mentagrophytes, but this antifungal activity had poorer durability to laundering.
