  • Spun-like hand yarn process
    Patent number: 4110965
    Abstract: Yarn comprising filaments of high and low elongations is false-twist heat-set. The yarn tension upon passage through the false twisting device is increased to a level sufficient to break the low elongation filaments, giving a yarn with a spun-like hand.

  • False-twist texturing process
    Patent number: 4028875
    Abstract: Thermoplastic multifilament feed yarns, such as polyester feed yarns are heatset in a twisted state at a temperature and under a tension so as to produce a torque yarn; and thereafter continuously, and at substantially the same tension, cooled, detwisted, and subjected to a second heat treatment so as to reduce the torque. If undrawn or partially drawn feed yarn is employed, the yarn may be orientation drawn during the texturing process.
