    摘要: A process is disclosed for producing a continuous multifilament yarn of melt-spinnable, polymeric material which is essentially free from stretch and which comprises draw-texturing a first continuous filament yarn end, combining the first end with a second flat continuous filament yarn end, and feeding the combined textured and flat ends through a jet interlacer in an overfeed condition with the textured end being fed at a greater rate of overfeed than that of the flat end. An alternate process is disclosed wherein draw-texturing of the first textured yarn end and drawing of the second flat yarn end are performed simultaneously prior to jet interlacing of the overfed combined ends. Also disclosed is the spun-like continuous multifilament yarn produced by the novel process as well as resulting fabric made from the yarn.

    摘要: A yarn is twist-drawn on an apparatus employing a 2-for-1 twist spindle; at least one guide roll positioned above the spindle; means suitable for receiving a yarn from said guide roll and drawing the yarn; and means suitable for winding the drawn yarn, wherein the guide roll comprises a cylindrical surface mounted on a shaft which is attached to a base suitable for positioning the cylindrical surface so that the yarn rides on the surface of the roll in a relatively fixed position and a substantial amount of twist is not trapped in the yarn ahead of the guide roll.

    摘要: In processing thermoplastic yarn a value is monitored to determine whether said value is above or below a predetermined value. The monitored value is related to the denier of the yarn and associated with a yarn plug. The interval for the monitored value associated with said yarn plug to oscillate with respect to said predetermined value is timed and the yarn is processed in response thereto.

    摘要: A yarn is twisted by passing the yarn wound on a package to a tensioning zone and then passing the yarn to a 2-for-1 twist spindle and twisting the yarn. The tension applied to the yarn in the tensioning zone is the result of the sinusoidal path of the yarn through the tension zone and is a function of the amplitude of the yarn passing through the sinusoidal path.
