Abstract
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.
