Definitions

  • the treatment develops the latent bulkiness of the yarn and imparts some entangling of the filaments of the yarn.
  • the resulting yarn has the bulk and filament coherency so that it can be utilized in high speed tufting machines with excellent mill efficiency.
  • the procedure involves gear-crimping of filamentary yarn and then passing the yarn under reduced tension through a jet wherein a pressurized heated fluid develops the latent bulkiness and entangles the filaments thereof.
  • the present invention provides a simple and effective way of controlling the uniformity of crimped yarn that is tangled and bulked in a jet device. Any variation from one end of yarn to another end is minimized.
  • a device for treating continuous multifilament yarn to bulk same and to entangle the filaments uniformly from one yarn end to another includes a yarn jet having a bore extending axially therethrough wherein the yarn is treated with a heated fluid as the yarn is overfed and moves longitudinally therethrough.
  • the device is preferably employed in the yarn path just after the yarn has been gearcrimped.
  • An eccentrically adjustably mounted guide adjacent the yarn entry port of the jet is used to deflect the yarn laterally as needed to assure tangle uniformity of the yarn from one processed yarn and to another end.
  • the yarn treated in the jet device is tested for tangles using known needle slip tests. If the measured number of tangles per unit of yarn is lower or higher than an established number, the extent to which the yarn is deflected is adjusted by proper movement of the eccentric guide.
  • FIG. 1 is a schematic representation of a preferred embodiment used for practicing the invention showing the jet device in longitudinal section.
  • FIG. 2 is an enlarged top view of the eccentric yarn guide shown in the first figure.
  • FIG. 3 is a central section showing an embodiment in which the jet insert and eccentric yarn guide are in a position that the yarn moving through the jet is not deflected as though no guide were used.
  • FIG. 4 is a schematic representation of another embodiment illustrating a different eccentric yarn guide.
  • FIG. 5 is a top view in partial section taken along line 5-5 in FIG. 4 showing the eccentric yarn guide.
  • FIG. 6 is an elevational view partly in section showing a part of the eccentric yarn guide of FIG. 5.
  • FIG. 1 apparatus is shown for crimping yarn and then bulking and tangling the filaments thereof in a controlled manner.
  • Numeral 1 denotes longitudinally moving synthetic thermoplastic filament yarn, such as nylon or polyester.
  • the yarn is drawn or partially drawn.
  • Crimp is imparted to the yarn by being passed through the mesh of crimping gears 2 and 3.
  • the yarn is shown as passing through the gears once, it is advantageous particularly for heavy denier yarns of 500 denier and up to pass the yarn between the gears two, three, or more times by using a separator roll (not shown) as is well known.
  • yarn 1 is overfed through an elongated yarn fluid jet device 4.
  • the device comprises a housing 5 having a fluid or steam inlet conduit 6 and a fluid or steam outlet conduit 7.
  • the fluid flows through the housing plenum 8 to provide a heated environment for the yarn as it passes through the device.
  • a venturi jet insert 10 is secured within the housing.
  • Such a jet is more particularly described in Lamb et al. US. Pat. No. 3,609,834.
  • the overfeed of the yarn through the jet is normally in the range of l5-60 percent.
  • the fluid is preferably steam of to 235C. moving at a high velocity.
  • Jet 10 as shown herein is composed of a cylindrical body 11 having a central yarn passage with flaring ends 12 and 13 and being constricted at point 14.
  • a plurality of fluid inlets are provided in the flaring end 13 .
  • a first inlet 15 is diametrically opposed to a second inlet 16 and just downstream is a third inlet 17.
  • the treating fluid is emitted in a direction sloping toward the point of yarn exit from the jet; and the emission is adjacent the point where the yarn passes through the expansion section of the jet venturi.
  • Treating fluid from plenum 8 flows through conduit 18 and via an annular chamber through the inlets into treating contact with yarn 1.
  • the yarn is collected in package form using, for example, a conventional winder and a paper tube.
  • Adjacent flaring end 12 of insert is a disc secured to the housing 5 by means of a set screw 21 in collar 22.
  • the collar is bolted to the housing by means of bolts 23.
  • Extending through the disc is an eccentrically arranged hole 24.
  • the disc is rotatably adjustable.
  • the disc has indicia for indicating the rotational position of the disc with reference to the departure of zero reference from the fixed line scored on collar 22.
  • the jet disc has been rotated to shift the yarn from taking a straight path through the jet to 15 one where the yarn is guided nearer the right side of the jet by the eccentric disc 20.
  • the disc is eccentrically mounted and is rotated to a position that the eccentric hole 24 is in alignment with the yarn passage through the insert 10 in which event the disc does not deflect the yarn to one side or the other.
  • the disc does not deflect the yarn to one side or the other.
  • it is not possible to align the eccentric hole with the yarn passage of the insert.
  • FIGS. 4-6 a different eccentric guide arrangement 25 is shown.
  • a collar 26 is bolted to the housing 5 just above the insert 10. Extending from collar 26 are a plurality of ears 27 adapted to mate with corresponding slots 28 on the internal surface of guide-carrying ring 29.
  • a yarn pigtail guide or eyelet 30 is secured to an upright portion 31 of the ring 29.
  • the guide is horizontally adjustable to deflect the yarn from a normally straight path taken through the collar and jet. By rotation of the ring 29 and horizontal movement of the guide 30, the precise entry angle of the yarn into the jet can be adjusted and controlled.
  • An illustrative example of the practice of the invention follows.
  • the yarns issuing from the hot-stretch gear crimping operation possessed a latent crimp or bulkiness that can be developed by heating the yarn under conditions of low tension as is well known.
  • the yarns were passed through separate fluid jets as disclosed in U.S. Pat. No. 3,609,834.
  • the amount of overfeed to the jet was 2 3 percent and the temperature of the stream used in the treatment was 185C.
  • the twenty ends of the resulting textured yarns were collected at a speed of 400 yards per minute on a paper tube using a conventional winder. Thereafter, the yarns were tufted into a woven jute backing material to make a pile carpet of high-low loop construction. During the commercial dyeing and finishing of the carpet the high pile sections were sheared.
  • the tangle counting device consists of a wheel having a peripheral groove with needles set therein to engage the yarn.
  • the wheel is set on a shaft that is loaded to resist turning, with the load being predetermined. Yarn undergoing testing is pulled over the 10 wheel with a needle slipping between the filaments.
  • a cam-switch assembly counts the number of times the wheel is advanced per unit length of yarn.
  • a system of guides and tensioning devices is used to maintain yarn position so that one needle is in contact with the yarn at all times during the test. Also, means for advancing the yarn at a uniform rate during testing is provided. The tangle count measured from 10 per 10 feet for one end up to 85 per 10 feet for another end of the 20 ends processed.
  • a device for treating continuous multifilament yarn to bulk same and uniformly to entangle the filaments thereof comprising:
  • a housing having a bore extending axially therethrough wherein the yarn normally is treated with a fluid as the yarn moves longitudinally therethrough;
  • a yarn processing assembly comprising in combifluid treatment from one such device to another c. a yarn guiding eyelet eccentrically adjustably Such devicemounted adjacent the yarn entry into said jet;
