Abstract: A method for the antimicrobial finishing of synthetic fibers, in which an aqueous solution of an organic primer component (P), such as, for example, gallic acid, and, as antimicrobial component (K), at least one organic quaternary ammonium compound, and a metal salt component (M) are applied at the same time or at a different time to the fibers, permits permanent antimicrobial finishing.

Abstract: An antimicrobial composition comprising an organic antimicrobial component (K) and at least one metal salt component (M) and also, where appropriate, a solvent (L) and further auxiliary components, which comprises as organic component (K) at least one compound of the general formula (I) where the radicals independently have for example the following meanings: R1 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R2 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R3 is a branched or unbranched alkyl radical having 1 to 12 carbon atoms, R4 is a branched or unbranched alkyl radical having 1 to 18 carbon atoms, R5 is a branched or unbranched alkyl radical having 1 to 18 carbon atoms, R6 is a branched or unbranched alkyl radical having 8 to 18 carbon atoms; n is an integer from 1 to 6, and which comprises as metal salt component (M) at least one salt of a di- to pentavalent metal, is useful for durable finishing of textiles.

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.

Abstract: The invention relates to a process for the production of silyl quaternary ammonium compounds comprising reacting a tertiary amine with a trialkoxy silane in the presence of a catalytic amount of an alkali metal or earth alkali metal iodide. The resulting compounds can be used directly without a further purification step.
