Abstract (en)
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.
