Definitions

  • ABSTRACT [22] Filed: Mar. 22, 1973 An improvement in an apparatus for commmglmg m- PP Flo-1343399 dividual filaments in multifilamcnt yarn is disclosed.
  • the prior art commin'gling jet is a body having a gas [52] US. Cl. .L 28/l.4 passageway intersecting with a yam plssagcwuy' The [51] Int.
  • Cl D02g 1/16 improvement is using a noncircular Orifice near the [58] Field of Search 28/l.4 72.12 exit of the gas Passageway at the intersection gas passageway with the yarn passageway so that gas [56] References Cited issues from the noncircular orifice to impinge on any UNITED STATES PATENTS yarn present in the yarn passageway.
  • This invention relates to an apparatus for commingling individual filaments and multifilament yarn. More particularly, this invention relates to a commingling jet with a body having a yarn passageway and gas passageway intersecting with the yarn passageway and an improvement comprising having a noncircular orifice near the intersection in the gas passageway so that gas issues from the noncircular orifice to impinge on the yarn present in the yarn passageway.
  • This invention is an improvement on the commingling jet disclosed in U.S. Pat. No. 3,473,315, issued Oct.
  • This invention is an improved apparatus for commingling individual filaments in a multifilament yarn.
  • the apparatus is a commingling jet with a body having a yarn passageway and a gas passageway intersecting the yarn passageway.
  • the improvement is providing the gas passageway with a noncircular orifice near the intersection with the yarn passageway so that gas issues from the noncircular disclosed to impinge on any yarn present, such as a continuous running length of yarn, in the yarn passageway as disclossed in U.S. Pat. No. 3,473,3l5 to LeNoir, incorporated by reference above.
  • the cross section of the noncircular orifice may be polygonal, preferably square.
  • the more preferred cross section is a V-shaped cross section having an are opposite the apex of the V so that the cross section of the orifice opening looks like a piece of pie.
  • This improved noncircular orifice of the gas passageway exit applies particularly to the apparatus for commingling individual filaments in the multifilament yarn at high speed where the body of the commingling jet has a yarn passageway made up of an inlet passageway and an outlet passageway where the inlet has a larger diameter than the outlet.
  • the inlet and the outlet are directly aligned on the same axis and the gas passageway intersects the yarn passageway at the junction of the inlet and the outlet at an angle of between about to about 75 as measured between axis of the gas passageway and the outlet of the yarn passageway.
  • This improved invention uses noncircular such as square or pie-shaped orifices to intensify the turbulent fluid stream at the impact point and increase the severity of entanglement and extend the working range of a commingling jet to achieve over 30 entanglements per meter at speeds of between 5,000 and 8,000 feet per minute.
  • the air entry tube in the prior art jet disclosed in U.S. Pat. No. 3,473,315 was replaced with a thin wall tube having at the exit end a V-shaped insert having a 60 V-angle.” Tests on a running length of yarn showed entanglement increased more than 10 entanglements per meter over the standard tube.
  • a similar tube equipped with a square port reduced the critical adjustment required with the single round port commingling jets and eased operability requirements.
  • yarn run was 2600 denier, textured yarn. This improvement in entanglement'level was achieved with no deleterious effect on properties of the yarn.
  • FIG. 1 is a cross sectional elevation of the jet commingling device of this invention.
  • FIG. 2 shows a cross section at the exit of the gas passageway.
  • FIGS. 1 and 2 show the preferred embodiment of this invention.
  • FIG. 1 is a cross section view of the body of the apparatus of this invention. Yarn enters yarn passageway 1 through yarn inlet 6 into yarn inlet passage- EXAMPLE
  • the device of this invention as shown in FIG. I, was successfully used to commingle a running length of 2600 denier, 140 filament textured nylon 6 carpet yarn at 5,000 feet perminute.
  • a special entanglement test based on the hook drop test is U.S. Pat. No. 2,985,995 (May 30, 1961 was used. 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 10 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, movesa fresh portion of yarn under the needle, inserts the needle, and starts the yarn moving.
  • an apparatus for commingling individual filaments in a multifilament yarn comprising a body having a yarn passageway and a gas passageway intersecting with said yarn passageway the improvement comprising said gas passageway having a noncircular orifice near said intersection with said yarn passageway, said noncircular orifice having a V-shaped cross-section with an arc opposite the apex, so that gas issues from said noncircular orifice to impinge on any yarn present in said yarn passageway.
  • an apparatus for commingling individual filaments in a multifilament yarn comprising a body having a yarn passageway made up of an inlet passageway and an outlet passageway said inlet having a larger diameter than said outlet, said inlet and outlet being directly aligned on the same axis, said body having a gas passageway intersecting said yarn passageway at the junction of said inlet and said outlet at an angle of between about 15 to about as measured between the axis of said gas passageway and said outlet yarn passageway, the improvement comprising said gas passageway having a noncircular orifice near said intersection with said yarn passageway.
  • said noncircular orifice having a V-shaped cross-section with an are opposite the apex, so that gas issues from said noncircular orifice to impinge on any yarn present in said yarn passageway.
