Definitions

  • ATTORNEYS YARN TEXTURING Synthetic fibers are commonly produced by extruding molten polymer through a spinneret.
  • a texturing process In order to produce yarns which have properties approximating those of wool or other natural materials, it is common practice to subject the extrudate from the spinneret to a texturing process. This can be ac complished by a'variety of procedures known in the art, such as stuffer-box crimping, false twisting, and fluid jet texturing.
  • One particularly effective procedure involves contacting the fiber with a high velocity fluid stream in a turbulent zone at an elevated temperature. The turbulence imparted to the fiber produces crimps which give the fiber a textured appearance.
  • the textured yarn from a fluid crimping zone is passed through an elongated chamber which contains a plurality of discrete members, such as balls or rods.
  • the textured yarn forms an elongated yarn wad which is surrounded by the stacked members. These members exert a force on the sides of the wad to confine the wad in a generally cylindrical or oval configuration.
  • the fluid introduced into the turbulent zone is permitted to escape through the voids between the individual members.
  • the resulting textured yarn can easily be removed from the top of the wad as it emerges from the removal chamber.
  • FIG. 1 illustrates a first embodiment of the apparatus of this invention which is employed to texture yarn.
  • FIG. 2 is a top view of a second embodiment of the apparatus.
  • FIG. 1 there is shown fluid texturing apparatus generally designed by reference numeral I0.
  • This apparatus comprises an elongated sleeve II which has a hollow needle 12 positioned in the inlet section thereof.
  • An elongated plug 14 is disposed in the outlet section of sleeve 11.
  • Plug 14 has a central opening 14b therethrough.
  • the inlet of opening l4b is tapered to provide a seat 14a adjacent the tip of needle 12.
  • the outlet of central opening 14b constitutes a flared section 140 of increasing diameter.
  • a conduit 17 communicates with sleeve 11 adjacent needle 12 to introduce a fluid, such as steam or air, at an elevated temperature.
  • a hollow chamber 18 having an inlet tube 18a is mounted immediately above sleeve 11 to receive yarn which is crimped in apparatus 10.
  • a large number of relatively small balls 19a and 19b are disposed within chamber 18.
  • Chamber 18 can be provided with an outlet conduit 21 which is connected to a drain or to a source of reduced pressure, not shown.
  • a screen 210 is positioned across conduit 21 to retain balls 19a and 19b within chamber 18.
  • one or more filaments a are inserted through needle I2 into the central passage of plug l4. These filaments can be delivered to the apparatus by any suitable feed means, not shown. In the normal start-up operation, the filaments are threaded completely through the apparatus. Fluid is introduced through conduit 17 and flows upwardly through plug 14 into chamber 18. The fluid so introduced surrounds needle 12 to elevate the temperature of the incomingfilaments. The velocity of the introduced fluid is sufficiently high to produce a zone of substantial turbulence in the flared outlet region Me of plug 14.
  • This turbulence imparts crimp to the filaments to produce textured yarn 20b.
  • the yarn passes upwardly to form an elongated generally cylindrical wad 200 in the center of chamber 18. This wad is surrounded and confined by balls 19a and 19b.
  • the yarn is cooled in passing through chamber 18 so that permanent crimps are imparted.
  • the resulting textured yarn 20d is removed through a take-up device 22 and passed to a storage zone, not shown.
  • the velocity and temperature of the fluid introduced through conduit 17 are such as to impart the desired degree of crimp in the yarn in the flared outlet section of plug 14 and in tube 18a.
  • an external heater can be employed to assist in elevating the temperature of the crimping apparatus 10.
  • the texturing fluid passes upwardly and escapes from the open top of chamber 18. When steam is employed as the texturing fluid, it may be desirable to provide vent conduit 21 to remove any condensate which may be formed. Balls 19a and 19b provide sufficient force to retain the yarn wad in a confined central region of chamber I8 for a period of time sufiicient to allow the yarn to be cooled to retain a permanent crimp.
  • balls 19 can be formed of metal, glass or any other material which is inert to the yarn at the temperatures encountered.
  • the balls are advantageously of spherical configuration, but this is not essential to the operation of the invention.
  • balls 19a are larger than balls 19b to provide better packing.
  • the balls can all be the same size.
  • the height of the balls in chamber 18 should be sufficient to permit the yarn to be cooled before removal from the chamber.
  • Any type of synthetic fiber which can be textured by the application of external forces at elevated temperatures can be treated by the process of this invention.
  • Typical fibers which can be so treated are polyolefins, nylons and polyesters, for example.
  • needle 12 has an internal diameter of about 0.06 inch.
  • the end of needle 12 is tapered at an angle of about 45, as is flared inlet 14a of plug 14.
  • the central passage 14b is about 1% inches in length and has an internal diameter of about 0.125 inch.
  • the flared outlet Me is about one-quarter inch in length and has an outlet diameter of about one-half inch.
  • Balls 19a have a diameter of about one'quarter inch; and balls 1% have a diameter of about one-eighth inch. Approximately percent of the total number of balls in chamber l8are balls 19a.
  • Chamber 18 has an internal diameter of about 3 inches, with the depth of balls being about 6 inches.
  • a bundle of I26 polypropylene filaments having a denier of about L800 (approximately l4 denier per filament) is introduced at a velocity of about 750 meters per minute.
  • Steam at I00 psig is introduced at a rate of about 20 pounds per hour.
  • the textured yarn is removed at a velocity of about 500 meters per minute.
  • a plurality of generally cylindrical rods 25 are disposed in chamber 18' in place of the balls. These rods are stacked in the chamber in the same manner as are the balls of FIG. I.
  • the resulting yarn wad 20c tends to be of oval cross-section.
  • the rods can be solid or hollow, and need not be of circular crosssection.
  • the individual rods can be the same or of different sizes.
  • the stack of rods exerts a force on the yarn wad in substantially the same manner as does the stack of walls in FIG. 1.
  • the chamber above apparatus l0 can contain individual members of various configurations having generally convex outer surfaces to facilitate stacking and exerting a confining force on the yarn wad.
  • a method of texturing yarn which comprises: passing yarn to be textured through a first passage into an enlarged zone which has a greater cross-sectional area than said passage;
  • Apparatus for texturing yarn comprising:
  • first passage through which yarn to be textured canbe directed, said first passage having an inlet and an outlet for the yarn;
  • conduit means communicating with the inlet of said first passage to introduce a fluid
  • said stacked members comprise rods which are stacked on one another and which extend in generally horizontal directions when said apparatus is positioned so that said chamber is located vertically above said second passage.
