ABSTRACT:
Polyester filaments in spin-oriented feed yarns, such as DTFY, and in draw-textured and other drawn yarns therefrom, and in fabrics and garments of such yarns, are prepared by an improved process involving treatment of the freshly-extruded polyester filaments with caustic in the spin-finish, so as to improve moisture-wicking properties.
