본 발명은 50 중량% 내지 99.99 중량%의 중합체, 10 wppm 내지 900 wppm의 아연, 1,000 wppm 미만의 인, 및 10 wppm 미만의 커플링제 및/또는 계면활성제를 포함하는, 항균 특성을 갖는 중합체 조성물에 관한 것으로서, 이때 아연은 중합체 내에 분산되고; 중합체 조성물로부터 형성된 섬유는 ISO20743:2013을 통해 측정된 0.90 초과의 클렙시엘라 뉴모니아에 로그 감소, 및/또는 ASTM E3160(2018)을 통해 측정된 1.5 초과의 에스케리치아 콜라이 로그 감소를 나타낸다. A polymer composition having antimicrobial properties, the composition comprising from 50 wt % to 99.99 wt % of a polymer, from 10 wppm to 900 wppm of zinc, less than 1000 wppm of phosphorus, and less than 10 wppm coupling agent and/or surfactant, wherein zinc is dispersed within the polymer; and wherein fibers formed from the polymer composition demonstrate a Klebsiella pneumonia log reduction greater than 0.90, as determined via ISO20743:2013 and/or an Escherichia coli log reduction greater than 1.5, as determined via ASTM E3160 (2018).
