Definitions

  • This invention relates generally to the continuous production of a warp beam of a multiplicity of merged or entangled yarns from a plurality of bobbins mounted in a creel.
  • Figure 1 is a side schematic view of the new and improved process and Figure 2 is a top view taken on line 2-2 of Figure 1.
  • the reference numbers 10 and 12 represent a false twisted single ply, 250 denier, 100 filament polyester yarns that are being supplied from bobbins 13 on a creel 14.
  • the yarn 10 is light grey and the yarn 12 is a dark grey in order to form a heather yarn 18 but it should be understood that other synthetic filament yarns, such as nylon, of different deniers, numbers of filaments and colours can be used within the scope of the invention.
  • the yarns 10 and 12 are delivered from the creel 14 to feed rolls 20 and 21 through a comb 22 which supplies one yarn 10 and one yarn 12 to each air entanglement jet 24 mounted on the air manifold 26 supplying air to each air jet 24 so that they operate at a pressure between 30 - 90 psi, preferably 60 psi, to entangle each pair of yarns 10 and 12. Since the yarns 10 and 12 are different colours, the entangled yarn 18 has a heather appearance and is basically a two ply, 250 denier, 200 filament yarn.
  • the output feed rolls 30 and 32 are supplying yarn to the warper 34 at a rate of 400 metres/minute which the input feed rolls are supplying yarn at a rate of about 409 metres providing an overfeed of yarn of about 2.3%.
  • This overfeed can vary between 1 and 4%.
  • the entangled yarns 18 Prior to the output rolls 30 and 32 the entangled yarns 18 each pass through a separate space in the dent 36 to maintain them separate as the feed rolls 30 and 32 feed them to the warp beam 38 of the warper 34.
  • the above described process provides an entangled yarn, preferably a heather yarn, warped and ready for use in a single continuous process from bobbins to the warp beam eliminating the intermediate steps of winding bobbins and recreeling at the warper to form a warp beam. Furthermore, the continuous system described provides a yarn having a heather hand and appearance especially when knit or woven into a fabric.
