Abstract (en)
An improved cationic-dyeable copolyester draw-texturing feed yarn that is novel in that the filaments are concentric sheath/core bicomponent filaments, the sheath consisting essentially of the cationic-dyeable polyester, whereas the core consists essentially of homopolymer, whereby such feed yarn may be draw-textured on commercially-available machines to give textured yarns with lower broken filament counts and improved bulk at economically viable costs.
