Abstract:
1. A process for finishing a woven or non-woven textile to render it resistant against colonization by mites, comprising the step of applying a formulation comprising zinc pyrithione and an antimicrobial active agent selected from the group consisting of triclosan, 2-n-octylisothiazolin-3-one, 1,2-benzisothiazolin-3-one, didecyldimethylammonium chloride, dimethyltetradecyl-[3-(trimethoxysilyl) propyl]ammonium chloride, didecylmethy-[3-(trimethoxysilyl)propyl]ammonium chloride, dimethyloctadecyl-[3-(trimethoxysilyl)propyl]ammonium chloride, poly(hexamethylenebiguanide) hydrochloride, and mixtures thereof to said textile, wherein the formulation comprises 2 wt % to 60 wt % zinc pyrithione, 3 wt % to 15 wt % antimicrobial active agent, a polymeric binder, and a hydrophobicizinq agent; wherein the textile is a furniture covering fabric or mattress ticking; wherein the formulation is applied by a padding process, a blade process, a spraying process, or a foam coating process, or as a powder or from a polymer melt; and wherein the concentration of zinc pyrithione, based on the dry finished textile, is between 600 and 10,000 ppm.
