ABSTRACT:
A process for producing a feed yarn which can be draw-textured, without difficulty with filaments melting or sticking together, to have a programmed distribution of deeper-dyeing sections along the resulting false-twist textured yarn. The feed yarn is prepared by passing a spin-oriented polyester yarn in substantially undrawn condition past a source of heat where it is heated intermittently along its length to provide a programmed distribution of heat-treated sections. When drawn, the heat-treated sections will draw to a lesser extent and will then dye to deeper shades than the rest of the yarn.
