摘要： A process and apparatus for making alternate S and Z twist plied yarn from individual singles yarns includes the steps of tensioning the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction, snubbing the yarn to restrain ply twisting so the twist in the singles yarn can equalize itself, stopping the forward movement of the yarn, then bonding the ply-twisted yarns at a node while applying twist, stopping the twisting operation, then repeating the procedure while twisting in the opposite direction. The ply twisted yarn has a lower defect level of less than 2.5 defects per 100 inch length of yarn.

摘要： A pile yarn for a carpet and a cut pile carpet.A bulky yarn of a polyamide multifilament is fed to a false twisting and heat setting device where filaments in the yarn are thermally and partially adhered to each other while the yarn is false twisted. A bulky cohesive continuous multifilament yarn thus obtained has alternate twists therein along the lengthwise direction thereof and a latent torque therein, and after it is heat treated under a constrained condition, preferably by means of saturated or superheated steam, so that the torque in the yarn is lowered, it is tufted on a substrate of a carpet as a pile yarn and the piles are cut.

摘要： An apparatus for twisting a fibre strand to have repeated along its length alternating zones of opposite twist comprises a fluid vortex device having two fluid inlets and a valve controlling fluid flow to the inlets. The valve comprises a hollow cylindrical rotatable valve member and a sleeve having a number of outlet ports surrounding the member. Fluid supplied to the hollow member is distributed to the outlet ports by rotation of the member. Plastics dry bearings between the member and the sleeve act to prevent improper flow of air along the abutting surfaces. The vortex device comprises a member formed with a bore, the bore having a wide port into which the fluid is injected through the inlets and a restricted port forming a venturi of diameter of the order twice that of the yarn. A plug through which the yarn passes at the end of the bore remote from the venturi inhibits escape of air from that end.

摘要： A stable plied yarn is produced by false-twisting two or more singles yarn strands with false-twist jets and passing the strands around a yarn wheel whereon the nodes are joined. The strands leave the wheel and ply together. The plied yarn is collected and can be tufted into carpet. The pressure of the fluid (air) supplied to the false-twist jets is varied to product varying amounts of twist in the singles strands which results in a range of twist amounts in the yarn plied therefrom, thereby avoiding streak effects in products made from the yarn.

摘要： Self-twist plural yarn strands are produced by a system wherein at least two singles yarn strands are individually twisted to form twisted strands each having longitudinally spaced nodes, and strands are brought together in a parallel relationship with the nodes of one strand substantially aligned with the nodes of each other strand. The corresponding nodes from one strand are fastened to those of each other strand, and the strands are allowed to ply. The node fastening means comprises a rotating member having a contact surface for fastening the nodes by gathering and twisting of the fibers from one strand with those of another strand at the nodes of each respective strand. Ply yarn twist uniformity is assured through the use of improved twist insertion jets, together with a means for holding singles yarns separate to allow longitudinal levelling of singles yarn torque prior to plying. .

摘要： Disclosed are novel yarns comprised of at least two, and preferably three, strands of filaments, being twisted about the other strands in random "s" and "z" directions in variant degress with filaments of each strand being interlaced together to produce a cohesive commingled yarn. The individual strands although interlaced with the other strands maintain substantial integrity in the commingled yarn and preferably have different dye affinities. Methods of manufacturing the novel yarns are also disclosed.
