ABSTRACT:
A cationic-dyeable copolyester draw-texturing feed yarn of concentric sheath/core bicomponent filaments, with a sheath of cationic-dyeable polyester, and a core of homopolymer, whereby such feed yarn may be draw-textured on commercially-available machines to give cationically-dyeable textured yarns with a combination of good tensile properties, low broken filament counts and good bulk at economically viable cost.
