  • Publication number: 20130037163
    Abstract: A bulked yarn comprising a bulked single spun yarn obtainable from a composite twisted yarn in which a single spun yarn and a water-soluble yarn together in a direction opposite to the twisting direction of the single spun yarn by dissolving and removing the water-soluble yarn in a hydrophilic solvent from the composite twisted yarn is prepared. When the bulked yarn with a length of 100 cm is hung down in a state where both ends of the yarn are fixed at a distance of 10 cm from each other in a direction perpendicular to the direction of gravitational force, twisting does not occur or an average value of the distances from the uppermost end of a twisting section to the first and second fixed ends of the yarn is 30 cm or more. The bulked yarn has excellent texture, lightweight properties, and anti-pilling properties, as well as excellent weaving and knitting properties and productivity.

  • Patent number: 5996328
    Abstract: Individual differently colored or colorable feed filament ends are withdrawn from respective creel-mounted packages and passed through a separation guide. The separation guide serves to "normalize" the filament end-to-end positions and tensions. That is, the separation guide will cause the individual feed ends to be in specific predetermined positions relative to the other feed ends regardless of the position of the package on the creel. In addition, the separation guide will effectively cause a short length of each feed end to be parallel to, and separated by a substantially uniform distance from, corresponding lengths of the other feed ends. This parallel alignment of individual end lengths and the substantially uniform filament end-to-end positioning thereby imparts substantially uniform tensions on the feed ends while substantially maintaining their respective positions in the combined yarn product relative to one another.

The cotton novelty yarn is made by separating cotton sliver into cotton fibers, and acting on the cotton fibers with a negative wire combing roll, and then twisting the cotton fibers into the cotton novelty yarn. The negative wire combing roll has a tooth angle of about -0.01 to -15.degree. (e.g. about -2.degree.). The novelty cotton yarn is combined with at least 10% conventional novelty yarn or non-slub open end or ring spun yarn and made into a warp of about 54-100 ends per inch, and may be ring dyed (with indigo, vat, sulphur, pigment or reactive dye) so that the core of the yarn remains white. The warp is woven with a filling yarn to produce a denim fabric with a weight of about 5 oz. -17 oz. per sq. yd. having the weave and yarn size selected so that a tight construction is provided which highlights the slubs.

  • Patent number: 5404706
    Abstract: Method and apparatus for high speed false twist texturing of yarns, which makes it possible to perform false twist texturing smoothly at a yarn speed of 1,000 m/min or higher. The number of false-twists inserted per meter of yarn is determined by Equation 1, while the yarn is false-twisted at a yarn speed satisfying Equation 2 and at a short yarn path length satisfying Equation 3: ##EQU1## wherein T is the number of false-twists inserted per meter of yarn, V is the yarn speed of false twist texturing (m/sec), L is the yarn path length from teed rollers to a false twister (m), and A is a cross sectional area of the yarn (m.sup.2), which is obtained by dividing the denier of the yarn by the density of the yarn. The false-twist texturing apparatus includes feed rollers feeding yarn to a false-twisting zone, a heating device bringing the yarn into direct contact with steam, a cooling device bringing the yarn into direct contact with water, a false twister and delivery rollers, in this order.

  • Patent number: 5392588
    Abstract: A method for spinning yarn produce the yarn having properties generally comparable to those of ring spun yarn. A rotatable hollow shaft having an entrance at one end and an exit at the other is rotatable about an axis extending in a direction A. A number of free fibers are fed in the linear direction A in a fiber mass, certain of the fibers having free trailing ends. The fiber mass is passed into the interior of the hollow rotatable shaft through the entrance. An air flow is established with respect to the shaft to effect separation of the free trailing ends of the fibers, preferably by establishing an air flow path that is initially substantially unidirectionally in direction A and then is deflected to move at an angle with respect to the direction A away from the shaft. The shaft is rotated at high speed about its axis so that the trailing ends of the fibers wrap around other portions of the fiber mass to produce a yarn, and the yarn is withdrawn through the exit of the shaft.

  • Patent number: 5372004
    Abstract: A draw texturing machine comprises a first heater for heating a yarn, a false twisting device for imparting twists to the yarn, and a cooling plate, disposed between the first heater and the false twisting device, for cooling the yarn which has been heated by the first heater and for inhibiting vibration of the yarn so as to allow the yarn to run in a stable manner. The cooling plate is provided with a yarn threading groove member having a bottom portion with which the yarn runs in contact and wall portions connected to the bottom portion to form a concave, downwardly directed opening. The wall portions of the yarn threading groove member are provided with a plurality of holes, and the bottom portion of the yarn threading groove member is provided with no holes.

  • Patent number: 5226271
    Abstract: A reverse stranding apparatus for the reverse stranding of conductors to produce cables or the like and to a method in connection with stranding and reverse stranding. The conductors are drawn from a distributor into a nozzle or equivalent through peripheral tubes circumferentially surrounding a central tube and being twistable about the central tube recurrently in opposite directions. To facilitate the passage of the conductor, a pressurized fluid is fed through the peripheral tubes upstream ends and into the peripheral tubes during the drawing of the conductors to produce oscillation, whereby the conductors passing through each peripheral tube remain substantially detached from the inner surfaces of the peripheral tubes.

  • Patent number: 5141780
    Abstract: The invention is directed to a process for producing bulked synthetic multifilament yarn comprising a plurality of continuous synthetic filaments having deposited thereon at intermittent intervals an adhesive polymer component having a melting temperature below that of the continuous synthetic filaments. The process comprises texturizing synthetic multifilament yarn to obtain desired bulk characteristics by directing heated yarn in a current of heated fluid against a yarn plug contained in a texturizing chamber, applying said adhesive polymer component in a molten condition to the surface of said yarn plug, and continuously discharging texturized yarn from said texturizing chamber at a lower linear rate than the feed rate of said yarn to said texturizing zone while said adhesive polymer component is still in a molten but solidifying state, resulting in bulked synthetic multifilament yarn having the adhesive polymer component deposited thereon at intermittent intervals.

  • Patent number: 4974302
    Abstract: For continuously crimping thermoplastic filaments, a filament bundle is blown by a jet nozzle into a stuffing chamber of a texturing wheel to produce a crimped filament bundle in the stuffing chamber. The stuffing chamber has a receiving zone, a treatment zone and a delivery zone. The filament bundle is subjected to a texturing or crimping treatment in the receiving zone and, depending upon the fiber material to be processed, undergoes a heating or cooling treatment in the treatment zone. The heating or cooling treatment is accomplished by a blowing agent which blows a gaseous medium into the stuffing chamber. At the delivery zone, the crimped filament bundle is taken-off or lifted-out of the stuffing chamber by fiber bundle-lifting means and moved towards a suction drum receiving the filament bundle.
