Abstract:
An article including a woven fabric comprising warp yarns and weft yarns, wherein at least one of either the warp yarns or the weft yarns includes: (a) a corespun elastic base yarn having a denier and including staple fiber and an elastic fiber core; and (b) a separate control yarn selected from the group consisting of a single filament yarn, a multiple filament yarn, a composite yarn, and combinations thereof; having a denier greater than zero to about 0.8 times the denier of the corespun elastic base yarn; wherein the woven fabric includes (1) a ratio of corespun base yarn ends to control yarn ends of up to about 6:1; or (2) a ratio of corespun base yarn picks to control yarn picks of up to about 6:1; or (3) both a ratio of corespun base yarn ends to control yarn ends of up to about 6:1; and a ratio of corespun base yarn picks to control yarn picks of up to about 6:1.
