ABSTRACT:
An improvement in the draw-texturizing process by the double heater method provides for application of pre-heat to the undrawn yarn so as to impart to the yarn sufficient tenacity to permit stringup. When stringup is completed, the undrawn yarn may be separated from the source of the pre-heat.
