Definitions

  • the apparatus comprises an elongated body having a straight yarn passageway with at least three orifices substantially equally spaced about the periphery of the body at substantially the same level.
  • the orifice center lines are offset so that at least two do not intersect with the center of the effective diameter of the yarn passageway, yet all pass within an imaginary circle having a diameter about one-third the effective diameter, and the same center as the effective diameter, at the orifice level.
  • at least two of the center lines extended from the orifices should pass outside the imaginary circle at the orifice level section having the same center but only 0.02 of the effective diameter of the yarn passageway.
  • the plane at the orifice level must be located within a length one-half the length of the yarn passageway and centered on the midpoint of the yarn passageway. These orifices communicate with a source of high pressure fluid.
  • the high pressure fluid flows through the orifices into the yarn passageway causing a vortex of swirling fluid so that any yarn passing linearly through the passageway would have filaments commingled with one another.
  • This improved process of entangling multififiment yarn can operate at from about 3,000 to about 8,000 feet per minute by passing continuous multifilament yarn through the above-described vortex.
  • At least three air orifices are spaced substantially equally at substantially the same level about the periphcry of the yarn passageway.
  • the orifice center lines are offset so that at least two do not intersect with the center of the effective diameter of the yarn passageway, yet all pass within an imaginary circle having a diameter about one-third the effective diameter, and the same center as the effective diameter, at the orifice level.
  • the resulting turbulent jet streams impinge asymmetrically in an annular area about the center line of the effective diameter of the yarn passageway and create a highly turbulent whirlpool or vortex that entangles or commingles the individual filaments in a continuous running strand of multifilament yarn.
  • the plane at the orifice level must be located within a length one-half the length of the yarn passageway and centered on the midpoint of the yarn passageway.
  • the improved apparatus for commingling continuous multifilament yarn of this invention comprises an elongated body having a straight yarn passageway passing through the elongated body and at least three orifices substantially equally spaced about the periphery of the elongated body at substantially the same level.
  • These orifices communicate with the passageway so that the center line of all the orifices, if extended, would pass within an area defined by a circle in a cross section at the orifice level having the same center as the effective diameter and having a maximum diameter of about 0.3 times the effective diameter of the yarn. passageway.
  • At least two of these extended center lines must pass outside the circle in the same cross section having the same center and about 0.02 times the effective diameter of the passageway.
  • the orifices communicate with a source of high pressure fluid.
  • the high pressure fluid flows into the orifice into the yarn passageway causing a vortex of swirling fluids so that any yarn passing linearly through the yarn passageway would have filaments commingled with one another.
  • effective diameter is meant a diameter of the largest circle which fits within and yet is tangent to the opposite sides of the narrowest dimension across the yarn passageway.
  • a circular yarn passageway has the same effective diameter as the actual passageway diameter.
  • a polygonal passageway such as a rectangle would have an effective diameter equal to the narrowest dimension of the polygon.
  • a rectangular yarn passageway would have an effective diameter equal to the narrowest dimension of the rectangle.
  • yarn guides can be placed about 2 inches above and below the entangling device to guide the yarn bundle through the highly turbulent whirlpool or vortex generated by the mixing of the three turbulent jet streams.
  • the device is slotted. Both the yarn passageway and the orifices admitting the commingling fluid may have circular or polygonal cross sections.
  • the preferred range of the inner diameter of the annular target area is from about 0.02 to about 0.03 times the effective diameter and from about 0.23 to about 0.3 times the effective diameter for the outer diameter of the annular area.
  • the fluid can be any fluid which can be jetted through an orifice such as nitrogen, steam or possibly even liquids. However, the preferred fluid is air.
  • the fluid pressure of between 30 and 90 psig is preferred. This results in a maximum air consumption of about 10 standard cubic feet per minute for each commingling device.
  • Tension on the yarn passing through the commingling device can be any tension which gives the desired amount of commingling. The preferred range is from about 0.03 to about 0.2 gram per denier.
  • the commingling device and method can be used on yarns of any denier but has been preferably used on 1,300 denier yarn or two ends of 1,300 denier yarn resulting in 2,600 denier yam.

  • Yarn entanglement as measured by a special entanglement tester can be as high as 50 or more entanglements per meter for 2,600/I40 denier yarns (two ends of 1,300 denier 70 filament) at 3,000 and 5,000 feet per minute. The following correlation has been obtained from experimental data at 3,000 feet per minute; E.P.M. 21.6 4.16:: 6.91.1, 0.061,, 0.0M,"
  • the dimensions of the commingling device used for this example were as follows.
  • the circular yarn passageway length was one inch.
  • the yarn passageway diameter was 0.180 inch.
  • Three orifices were used at one-half inch from top. Each orifice diameter was 0.055 inch.
  • At least two orifice center lines, extended, were outside a circle having the same center as the yarn passageway but having a 0.004 inch diameter. All three orifice center lines extended were within an outer circle having 0.060 inch diameter.
  • the special entanglement test is based on the hookdrop test in US. Pat. No. 2,985,995, May 30, 1961. This test has been modified to the special entanglement per meter test as follows. An entanglement among the filaments in the yarn bundle is so identified when it has the cohesion to hold a gram hook which is allowed to slowly move down through the yarn.
  • the entanglement tester counts the number of times a needle with a 40 gram trigger pull" in a horizontally moving yarn is stopped.”
  • the instrument counts the stop, raises the needle, moves a fresh portion of yarn under the needle, inserts the needle, and starts the yarn moving.

  • Inner body 1 has yarn passageway 2 passing longitudinally through it.
  • Inner body 1 also has off-set orifices 3 spaced substantially equally about the diameter of yarn passageway 2. These orifices are off-set so that the center line of each orifice, if extended, would not pass through the center line of the yarn passageway 2.
  • Orifices 3 communicate with manifold 4 which in turn communicates with large orifice 7 in register with tube fitting 6 which is secured to outer body 5.
  • Outer body 5 also contains string-up slot defined by the surfaces labeled 8 and 9. The string-up slot has a flared opening 10.
