ABSTRACT:
Antimicrobial activity is imparted to nylon during its preparation by adding to the nylon-forming monomer(s), a zinc compound (e.g. zinc ammonium carbonate) and a phosphorus compound (e.g. benzene phosphinic acid). The compounds are added in amounts sufficient to form in situ a reaction product containing at least 300 ppm of zinc, based on the weight of nylon prepared. Fibers made from the resulting nylon contain the reaction product uniformly dispersed therein and have antimicrobial activity of a permanent nature.
