Zusammenfassung:	The present disclosure relates to a nonwoven polyamide structure having antimicrobial properties comprising: nonwoven polyamide fibers comprising less than 4000 ppm zinc dispersed within the nonwoven polyamide fibers; and less than 2000 ppm phosphorus. The fibers have an average fiber diameter of less than 25 microns; and the polyamide structure demonstrates a Staphylococcus aureus reduction of at least 90%, as measured by ISO 20743-13.
