The use is described of zinc pyrithione for finishing woven and non-woven textiles to render them resistant against colonization by house dust mites. Zinc pyrithione is used alone or in combination with other actives with or without other textile chemicals. The formulations comprising zinc pyrithione are applied to the textiles using the standard processes of textile finishing, such that there is a concentration of preferably 1000 to 6000 ppm of zinc pyrithione on the textile. This gives on uncoated sheetlike textiles a very distinct reduction in the mite population in testing; ideal finishes even eliminate the mite population completely.

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-b
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; andwherein the concentration of zinc pyrithione, based on the dry finished textile, is between 600 and 10,000 ppm. 2. A process according to claim 1, wherein the formulation comprising zinc pyrithione and the antimicrobial active agent optionally comprises another antimicrobial active agent or a textile chemical and is applied to the textile such that the applied concentration of zinc pyrithione, based on dry fabric weight of the textile to be finished, is between 600 and 10,000 ppm. 3. A process according to claim 2, wherein the applied concentration of zinc pyrithione, based on dry fabric weight of the textile to be finished, is between 1000 ppm and 6000 ppm. 4. A process according to claim 3, wherein the applied concentration of zinc pyrithione, based on dry fabric weight of the textile to be finished, is between 1500 and 3000 ppm. 5. A process according to claim 1, wherein the formulation comprises 10 wt % to 50 wt % zinc pyrithione. 6. A process according to claim 5, wherein the formulation comprises 10 wt % to 30 wt % zinc pyrithione. 7. A process according to claim 1, wherein: the formulation comprises 10 wt % to 50 wt % zinc pyrithione, 3 wt % to 15 wt % triclosan, and the hydrophobicizing agent is a fluorocarbon hydrophobicizing agent;the formulation is applied by padding or a blade coating process; andthe concentration of zinc pyrithione, based on the dry finished textile, is between 1,000 and 6,000 ppm. 8. A process according to claim 7, wherein: the formulation comprises 10 wt % to 30 wt % zinc pyrithione and 3 wt % to 15 wt % triclosan; andthe concentration of zinc pyrithione, based on the dry finished textile, is between 1,500 and 3,000 ppm. 9. A process according to claim 1, wherein: the formulation comprises 3 wt % to 35 wt % zinc pyrithione; andthe concentration of zinc pyrithione, based on the dry finished textile, is between 1,000 and 6,000 ppm. 10. A process according to claim 9, wherein: the formulation comprises 5 wt % to 15 wt % zinc pyrithione and 3 wt % to 15 wt % triclosan; andthe concentration of zinc pyrithione, based on the dry finished textile, is between 1,500 and 3,000 ppm.
