Definitions

  • the following disclosure relates to a device for producing a fancy yarn constituted of a main yarn and decorative fibers interlaced with the main yarn.
  • PTL 1 discloses a related art.
  • decorative fibers are supplied sideways onto a running main yarn and further a sub yarn is interlaced with them to produce a fancy yarn with the decorative fibers tangled therein.
  • this art enables production of a fancy yarn by a simple device, decorative fibers could happen not to get tangled in desired sites in the main yarn and, in a worst situation, fail to get tangled in the main yarn and then fall off.
  • a production device for producing a fancy yarn from first and second yarns, which interlace with each other and thereby form a main yarn, and a decorative yarn is provided with: a first feeding creel for feeding the first yarn; a second feeding creel for feeding the second yarn; a confluence region to make the first yarn and the second yarn flow together along an axial direction; a cutter to intermittently cut the decorative yarn into decorative fibers; an ejection nozzle for feeding the decorative fibers to the confluence region; and a processing device to bundle the first yarn, the second yarn made to flow together with the first yarn, and the decorative fibers.
  • upstream and downstream are defined with respect to a direction where a main yarn runs and a term “axial direction” means the same direction unless otherwise described.
  • a device is preferably applicable to production of a fancy yarn 10 at least including a main yarn 1, 3 and decorative fibers 5c, into which a raw fiber is intermittently cut, interlaced with the main yarn, as shown in FIGs. 6A through 6C .
  • the fancy yarn 10 may be used in fabrics or knits for example to give decorative effects thereto.
  • the device is in general provided with first and second feeding creels 11, 13 for feeding first and second yarns 1, 3 constituting the main yarn, a confluence region 17 where the yarns 1, 3 and the decorative fibers 5c get to flow together, a twisting device 23 and a winder 31.
  • These feeding creels 11, 13 are not necessarily disposed symmetrically as illustrated whereas preferably these elements are so disposed that the yarns 1, 3 run in an axial-symmetrical form at least in the confluence region 17. Any yarn guides such as rings or rollers may be properly arranged to guide the yarns 1, 3 in such a form.
  • the device is further provided with an assembly for feeding the decorative fibers 5c to the confluence region 17.
  • This feeding assembly is for example provided with a third feeding creel 15 for feeding the decorative yarn 5, an ejection nozzle 19 for guiding an airflow A1, and a cutter 21.
  • the decorative yarn 5 fed from the third feeding creel 15 is made to pass through the ejection nozzle 19, intermittently cut by the cutter 21 into the decorative fibers 5c, and then fed by the airflow A1 to the confluence region 17, thereby forming a confluent flow with the yarns 1, 3.
  • the ejection 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 ejection nozzle 19 from the one end to the other.
  • the decorative yarn 5 is drawn out of the decorative yarn creel 15, introduced through the upper end into the ejection nozzle 19, rides on the airflow A1, and is then expelled from the lower end.
  • the cutter 21 is disposed for example between the ejection nozzle 19 and the confluence region 17.
  • the cutter 21 is for example an edged hook.
  • FIG. 2 illustrates that the cutter 21 is disposed outside the ejection nozzle 19, alternatively it may be inside the ejection nozzle 19.
  • the decorative yarn 5 is steadily given tension by the airflow A1 and is, when touching the cutter 21, readily cut off.
  • the decorative yarn 5 may be intermittently fed and, for this purpose, the decorative yarn creel 15 may be provided with a servomotor.
  • the roller guiding the decorative yarn 5 may be provided with a servomotor.
  • an intermittently working clamp may be used. The clamp may be disposed outside the ejection nozzle 19 or built in the ejection nozzle 19. The running decorative yarn 5, when being halted by these means, touches the cutter 21 and is thereby cut.
  • the cutter 21 may be alternatively scissors or clippers instead of the edged hook, and may be provided with a driver device such as a motor or a solenoid mechanism for driving them. Still alternatively, any thermal means or a laser may be used to cut the decorative yarn 5.
  • the device for cutting the decorative yarn 5 may be disposed upstream of the ejection nozzle 19.
  • the device may be provided with a clamp for temporarily holding the decorative fibers 5c.
  • the decorative fibers 5c cut in advance get ready there and are, as this clamp releases them, fed to the confluence region 17 in sequence.
  • the cut off decorative fibers 5c ride on the airflow A1 and fly toward the confluence region 17.
  • the ejection nozzle 19 should be so oriented that the decorative fibers 5c reach a field just where yarns 1, 3 get to flow together. This particularly urges the decorative fibers 5c to tangle with the yarns 1, 3 without falling off.
  • the direction of the ejection nozzle 19, the direction of the airflow A1 and the direction where the yarns 1, 3 run after the confluence may be made mutually consistent. This further urges the decorative fibers 5c to tangle with the yarns 1, 3.
  • the direction of the ejection nozzle 19 or the direction where the yarns 1, 3 run or both may be made vertical and in this case the ejection nozzle 19 may be disposed vertically upward from the confluence region 17.
  • These configurations may further urge the decorative fibers 5c to tangle with the yarns 1, 3.
  • to be vertical is not essential but they may be oblique or horizontal and even in this case the decorative fibers 5c could ride on the airflow A1 to reach the confluence region 17.
  • Such a single feeding assembly may be used whereas the device may be provided with plural sets of feeding assemblies.
  • the device may respectively feed mutually distinct kinds of yarns in terms of colors, thickness or any other properties.
  • the confluence region 17 may be an open space or properly confined.
  • a guide for guiding the yarns 1, 3 and the decorative fibers 5c may be used.
  • the guide is provided with a hollow cylinder 39 elongated in its axial direction for example.
  • the cylinder 39 is opened at one end (normally its lower end) where the introduced yarns 1, 3 along with the decorative fibers 5c are expelled out.
  • the interior of the cylinder 39 is provided with an internal space elongated along the axial direction, which is so dimensioned as to allow the yarns 1, 3 to swirl to some degree around the axial direction.
  • the cylinder 39 may be, on its side faces for example, further provided with openings 41, 43 for respectively introducing the yarns 1, 3.
  • the decorative fibers 5c are introduced through the other end (normally its upper end) of the cylinder 39 and guided to the yarns 1, 3.
  • the other end of the cylinder 39 may be continuous to the ejection nozzle 19 in order to introduce the fibers or may be opened away from the ejection nozzle 19.
  • the other end of the cylinder 39 may be as shown provided with tubes 45a, 45b and 45c.
  • a single tube, or a plurality of tubes 45a, 45b, 45c correspondingly to the plural sets of feeding assemblies as shown, may be used.
  • the tubes 45a, 45b, 45c may be continuous respectively to the ejection nozzles 19 or may be opened away from the ejection nozzles 19.
  • the tubes 45a, 45b, 45c are all continuous to the cylinder 39 and also in spatial communication with its internal space.
  • the cutter 21, and also the aforementioned clamps, may be built in the tubes 45a, 45b, 45c or interposed between the tubes 45a, 45b, 45c and the cylinder 39.
  • the combination of the tubes 45a, 45b, 45c and the cylinder 39 guides the decorative fibers 5c to the yarns 1, 3.
  • a swirling nozzle 23 which is disposed just downstream from the confluence region 17, particularly from its guide.
  • the swirling nozzle 23 is an air nozzle creating an airflow swirling around the yarns.
  • a processing device 29 may be used and one of its examples is an interlacing nozzle.
  • the interlacing nozzle is disposed downstream from the confluence region 17, and from the swirling nozzle 23.
  • any publicly known interlacing nozzle is applicable to the processing device 29.
  • the interlacing nozzle is for example provided with a guiding hole 51 through which the yarn passes and an air duct 53 in communication with the guiding hole 51.
  • the air duct 53 is connected to an external air-blast device such as a blower and is made thinner at least at its end toward the guiding hole 51, thereby ejecting relatively high-speed air flow A4 into the guiding hole 51.
  • the air flow A4 ejected in the guiding hole 51 creates relatively high-speed turbulent flow around its outlet, which gives interlacement to the yarns passing through the guiding hole 51.
  • the interlacing nozzle may be provided with a water nozzle for applying a small amount of water to the yarns, or the water nozzle may be installed upstream from the interlacing nozzle.
  • the yarns 1, 3 and the decorative fibers 5c given water pass through the interlacing nozzle, the yarns 1, 3 are bundled together and are, along with the decorative fibers 5c, interlaced with each other, thereby the fancy yarn 10 as shown in FIG. 6C is provided.
  • the fancy yarn 10 is taken to the winder 31.
  • a publicly known interlace nozzle may be instead used, or any false-twist device such as a combination of a hollow spindle or a friction-type twisting device and a heater may be used.
  • any real-twist device is applicable.
  • a real-twist device is a combination of a twister and a spindle for example.
  • the spindle can also function as a winder.
  • a real twist can cause the decorative fibers 5c to securely tangle in the yarns 1, 3, and thus the yarns 1, 3 are more tightly bundled together.
  • heating and adhesion are applicable.
  • heating means a heater, a laser oscillator and an ultrasonic generator may be exemplified.
  • the fancy yarn 10 has structures with relatively long naps constituted of shortly cut decorative fibers 5c. Although each structure resembles naps, they less likely fall off as real naps do because they firmly tangle in the yarns 1, 3.
  • each structure may have each modified magnitude and modified interval.
  • distinct colors could be given to the respective structures.
  • the decorative fibers 5c are thrown into the yarns 1, 3 that are swirling and simultaneously form a confluent flow, and just to sites where the yarn 1 and the yarn 3 tangle together. Therefore the decorative fibers 5c are prevented from failing to tangle with the yarns exactly at desired positions or falling off.
  • a production device which provides a new option for the art of fancy yarns.
