Abstract: The present disclosure discloses a high resilience and stain resistant bulked continuous filament yarn. The yarn comprises a plurality of continuous filaments of polybutylene terephthalate (PBT), wherein the polybutylene terephthalate (PBT) has intrinsic viscosity in the range of 0.8 to 1.3. The yarn is obtained by a process comprising melt spinning of the plurality of continuous filaments of PBT; extrusion of the plurality of continuous filaments; quenching of the extruded filaments; drawing of the quenched filaments; texturizing of the drawn filaments; cooling of the texturized filaments, overfeeding of the cooled-texturized filaments; and winding of the overfeed filaments with or without tangling for obtaining the high resilience and stain resistant bulked continuous filament yarn. The high resilience and stain resistant bulked continuous filament yarn has a stain resistance rating of more than 3 and a hexapod rating of 2 or more after 12000 cycles.

Abstract: 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 may include one of polybutylene terephthalate (PBT) or polyethylene terephthalate (PET), or polyamides, or polypropylene. Further, the herbal masterbatch may include: (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 same as the base polymer and may include one of: PBT, PET, polyamides or polypropylene. To make a polymeric yarn, the herbal masterbatch and the base polymer may be 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.

Abstract: A process and system for manufacturing twisted and textured yarns are provided. The process includes drawing a first material yarn from a first supply source under predetermined tension; heatingly extending the first material yarn through at least one first heating godet; drawing a second material yarn from a second supply source under predetermined tensions; heatingly extending the second material yarn through at least one second heating godet; feeding at least one of the first material yarn and the second material yarn in an Air Textured Unit (ATY) to obtain a third material yarn; winding the third material yarn exiting from the ATY, wherein the winding is a pirn winding process; twisting the first material yarn, the second material yarn and the third material yarn; and rewinding the twisted third material yarn.
