Abstract
The present disclosure relates the polymer compositions, fibers, and yarns having near-permanent antimicrobial activity, and a method of producing the same. In one embodiment, the antimicrobial polymer composition from 50 wt % to 99.9 wt % of a polymer, from 5 wppm to 1000 wppm of zinc, and from 0.005 wt % to 1 wt % of phosphorus, wherein fibers formed from the polymer composition demonstrate a zinc retention rate of greater than 20% when tested in a dye bath test.
