Abstract (en)
A polymeric yarn composition having antimicrobial and/or antibacterial properties includes: (i) an herbal masterbatch in a range of 0.01%w/w to 10%w/w, and (ii) a base polymer in a range of 90%w/w to 99.99%w/w. The base polymer includes one of polybutylene terephthalate (PBT) or polyethylene terephthalate (PET), or polyamides, or polypropylene. Further, the herbal masterbatch includes: (a) an herbal component includes Neem or Turmeric or combination thereof in a range of 1%w/w to 75%w/w, and (b) a carrier polymer in a range of 25%w/w to 99%w/w. The carrier polymer may be the same as the base polymer and includes one of: PBT, PET, polyamides or polypropylene. To make a polymeric yarn, the herbal masterbatch and the base polymer are melted and extruded together to obtain the polymeric yarn having the herbal component in a range of 0.01% to 10% in weight of the polymeric yarn.
