Abstract
Provided is a textile made of filament yarn comprising a polymer composition that is durable and reusable having permanent or near-permanent antiviral properties and that includes a polymer, a metal ion, preferably a zinc and/or copper ion, and an optional phosphorus compound, wherein fibers and/or fabric formed from the polymer composition demonstrate antiviral properties and wherein the polymer is hygroscopic. The present disclosure also describes methods of forming the polymer compositions and methods of preparing fibers from the polymer composition.
