Abstract (en)
A core spun yarn comprising a bi-component polyester filament and an elastomeric fiber. The polyester filament has a denier from about 20 to about 150 and the elastomeric fiber has a denier from 20 to 140. The polyester filament is about 2 weight percent to about 60 weight percent, based on total weight of the yarn and the elastomeric fiber is from about 1 percent to about 40 percent, based on total weight of the yarn. The elastomeric fiber may have higher draft than the bi-component polyester fiber. The polyester filament comprises poly (trimethylene terephthalate) and at least one polymer selected from the group consisting of poly (ethylene terephthalate) and poly (tetramethylene terephthalate) and said elastomeric fiber is spandex. The yarn may include a sheath of at least one staple fiber. The disclosure also includes a fabric of the bi-component polyester filament and an elastomeric fiber.
