    摘要: This invention concerns the false twisting of strands as for example, yarns, tapes and films. The false twisting is effected as the strand is continuously travelled around a freely rotatable roller in the form of a loop, the beginning and end of which constitutes a close simple knot in contact with the roller periphery. The frictional contact of the strand with itself at the knot causes false twist to run back in the strand. The stand leaves the roller in a non-tangential direction. This method of false twisting may be used as a substitute for known methods in the production of modified continuous filament yarns, or to produce preliminary or additive false twist in such cases; in the treatment of wet-spun linen yarns to improve their characteristics; and in the treatment of film either to separate pre-formed filaments therein or to fibrillate it.

    摘要: Yarn is false twisted first in one sense and then in the opposite sense to produce an essentially zero torque texturized yarn. For this purpose, false twist spindles are provided to twist the yarn in opposite senses.

    摘要: The present invention is an apparatus and method of making yarn for carpet that exhibits a high degree of color pop. More specifically, in one aspect, the present invention comprises an apparatus and method that comprises supplying a plurality of yarns, false-twist the plurality of yarns, and passing the consolidated yarn through a downstream entangling assembly to tack at least a portion of the consolidated yarn. Another aspect of the present invention passes at least one of the plurality of yarns through one of a plurality of second entangling assemblies positioned upstream of the false-twist apparatus.

    摘要: A method of producing a bulky yarn having a controlled residual torque, which comprises subjecting a thermoplastic synthetic filament yarn to a series of twisting, heat-setting on a first heater, and untwisting, feeding the yarn into a second heater while rotating it by means of a fluid nozzle and re-heat-setting the yarn in the second heater, the yarn being maintained in a substantially relaxed state during the rotation by the fluid nozzle and the re-heat-setting by the second heater.

    摘要: A process for the continuous production of moderately elastic crimp yarn from unstretched synthetic filaments by false-twist crimping, wherein the unstretched synthetic filaments are initially fully stretched under heat with a slight false-twist, after which they are subjected in the same operation to falsetwist crimping under heat in the opposite direction and wound up under relaxation. Stretching is carried out at stretching ratios of from 1:3 to 1:6 and at temperatures of from 80* to 180* C.
