Abstract

Fibers and filaments of synthetic polymers containing from 0.1 to 5%, by weight, based on polymer, of an azole compound corresponding to the following general formula: ##STR1## and from 0.1 to 5%, by weight, based on polymer, of a dihydroxydiphenylmethane derivative corresponding to the following general formula: ##STR2## wherein n represents 0 or 1; PA1 m represents 0, 1 or 2; PA1 R.sub.1 represents halogen, halophenyl or phenyl; PA1 R.sub.2 represents --CO--C(CH.sub.3).sub.3 or --CHOH--C(CH.sub.3).sub.3 ; and PA1 R.sub.3 and R.sub.4 represent halogen, show laundry-stable, antimicrobial activity.
