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.

Claims

1-28. -28. (canceled)

29. A method for the antimicrobial finishing of textiles, fibers, or yarns which consist essentially of synthetic materials, comprising the step of applying to a textile, fiber, or yarn, at the same or a different time:

an aqueous solution of an organic primer component (P), which increases the hydrophobicity of the surface of the textiles or fibers, and is selected from the group consisting of;

an aromatic mono- or dicarboxylic acid, which may be substituted by hydroxy groups;

an aromatic mono- and diamine;

an aromatic mono- or dialcohol;

an aliphatic mono- or dicarboxylic acid having 6 to 26 carbon atoms, which each may be substituted by hydroxy or amino groups;

aliphatic, primary, secondary or tertiary amines having 6 to 26 carbon atoms;

an aliphatic, primary or secondary alcohol having 6 to 26 carbon atoms;

an aliphatic, primary mercaptan having 6 to 26 carbon atoms;

an amino acid; and

mixtures thereof;

an antimicrobial component (K) of at least one organic quaternary ammonium compound of the general formula (I)
