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.

Abstract: A method for measuring the attraction propensity of fabric including the steps of charging a neutralized test fabric, optionally by contacting with a charging fabric, presenting the charged test fabric a predetermined distance from a static-influenced agent such that at least a portion of the static-influenced agent attaches to the charged test fabric, and determining the quantity of attached static-influenced agent.
