Definitions

  • PTL 1 discloses a related art. Further relevant prior art is described in JP S62 85042 A and JP H01 104839 A .
  • a production device for a fancy yarn including a main yarn and a decorative yarn intermittently cut and tangled in the main yarn is provided with a confluence region to put the decorative yarn along the main yarn; a main feeding creel for feeding the main yarn to the confluence region; a jet nozzle for feeding the decorative yarn along with air flow to the confluence region; a cutter to intermittently cut the decorative yarn; and a twisting device to create a real twist or a false twist in the main yarn with the decorative yarn, wherein the production device is configured that the cut decorative yarn is blown by and flies with the air flow of the jet nozzle toward the main yarn to be put along the main yarn and into confluent motion therewith.
  • a device is preferably applicable to production of a fancy yarn 10 at least including a main yarn 1 and decorative fibers 5c, into which a raw fiber is intermittently cut, tangled in the main yarn 1, and capable of including a sub yarn 3 as well, as shown in FIGs. 6A through 6C .
  • the fancy yarn 10 may be used in fabrics or knits for example to cause decorative effects thereon.
  • the device is in general provided with a main feeding creel 11 for feeding the main yarn 1, a decorative yarn creel 15 for feeding a decorative yarn 5, a twisting device 23 and a winder 31.
  • the main yarn 1 runs from the main feeding creel 11 through a confluence region 17 to the twisting device 23.
  • any yarn guides such as rings and rollers may be disposed properly.
  • the device is further provided with a jet nozzle 19 for guiding air flow A1.
  • the decorative yarn 5 is made to pass through the jet nozzle 19, intermittently cut by means of a cutter 21 into the decorative fibers 5c, and fed by means of the air flow A1 to the confluence region 17 to start flowing together with the main yarn 1 there.
  • the device may further include a sub yarn creel 13 for feeding a sub yarn 3.
  • the twisting device 23 is disposed downstream from the confluence region 17 or, in a case where the sub yarn 3 flows together, disposed downstream from the area at issue.
  • the twisting device 23 is for example a false twister and the whole of the yarns 1, 3 and the decorative fibers 5c is thereby given a false twist to form the fancy yarn 10 and then taken up by the winder 31.
  • a real twist may be given thereto as described later.
  • additional feeding creels may be further added in order to feed two or more main yarns or sub yarns.
  • two or more decorative yarns may be available and, in such a case, a set of a decorative yarn creel, a jet nozzle, a cutter and a confluence region should be added.
  • Two or more decorative yarns may vary in color and/or in thickness.
  • the jet nozzle 19 is for example an elongated hollow tube, one end of which is connected to an air-blast device such as a blower and the other end of which is opened toward the confluence region 17.
  • an air-blast device such as a blower
  • the air flow A1 by the air-blast device steadily flows through the jet nozzle 19 from the one end to the other.
  • the decorative yarn 5 is drawn out of the decorative yarn creel 15, led through around the one end into the jet nozzle 19, and expelled out of the other end along with the air flow A1.
  • the cutter 21 is disposed in the jet nozzle 19 or between the jet nozzle 19 and the confluence region 17.
  • the cutter 21 is for example an edged hook.
  • the decorative yarn 5 expelled from the jet nozzle 19 steadily flutters and then touches the cutter 21, thereby being cut.
  • scissors or clippers are applicable to the cutter 21 and a driver device such as a motor mechanism or a solenoid mechanism may be provided in order to drive the scissors or the clippers.
  • any thermal means or a laser may be used to cut the decorative yarn 5.
  • the device may be provided with one or more walls 33 in order to rectify the air flow at the confluence region 17. At least one of the walls 33 may be disposed in a direction and at a position adapted to rectify the air flow A1 toward the main yarn 1. As well, another of the walls 33 may be disposed to rectify the air flow in a direction where the main yarn 1 runs for example. These walls are beneficial in tangling the decorative fibers 5c into the main yarn 1.
  • the cutter 21 may be, besides, outside the jet nozzle 19 as shown in FIG. 2 . but may be disposed inside the jet nozzle 19 as shown in FIG. 4 . Moreover, downstream from the cutter 21, the device may be provided with a second clamp 19B. According to this construction, the decorative fibers 5c cut in advance get ready there and are, as the second clamp 19B releases them, fed to the confluence region 17 in sequence.
  • a swirling nozzle such as an air nozzle 23 may be used, which swirls the air flow to give a false twist to a yarn.
  • the swirling nozzle swirls the main and sub yarns 1, 3 to promote incorporation of the decorative fibers 5c into the main and sub yarns 1, 3. This is beneficial in preventing the decorative fibers 5c from falling off.
  • a hollow spindle for example may be used. Further in place thereof or in addition thereto, heat or such may be made to act thereon.
  • an interlace nozzle may be instead used.
  • a yarn processing device such as a combination of a hollow spindle or a friction-type twisting device and a heater may be used.
  • heating and adhesion are applicable.
  • a heater, a laser oscillator and an ultra-sonic generator may be exemplified.
  • This structure can be arbitrarily changed depending on the length of cutting the decorative yarn and intervals between adjacent structures can be arbitrarily changed by changing intervals of cutting the decorative yarn. Moreover, needless to say, as two or more decorative yarns can be used, distinct colors could be given to the respective structures.
  • a production device which provides a new option for the art of fancy yarns.
