Definitions

  • the present disclosure relates especially to textile industries, and, more particularly, to a polymeric yarn and composition having antimicrobial and/or antibacterial properties.
  • Textile industry has conventionally been using both natural and synthetic fibers for manufacture of various products. Each having their own advantages and shortcomings related to strength, comfort, softness, longevity and the like. With ever-increasing demand to provide enhanced quality fibers manufacturers apart from enhancing traditional properties, have started incorporating more functional elements to fibers to provide better comfort, freshness, and hygiene to users.
