Definitions

  • This invention relates to'an apparatus and method for spinning synthetic filament yarns and to special filament yarns produced therefrom. More particularly, this in-- vention relates to a novel method and apparatus for quenching thermoplastic filaments and to special bumpy filament yarns produced therefrom.
  • Freshly spun molten filaments are quenched by passing them through a cooling unit referred to as a quench chimney, a quench chamber, or a quench box.
  • Freshly spun molten filaments issuing from a spinneret pass through the quench chimney and extend to a convergence guide mounted at the bottom thereof where the filaments are bundled into a yarn.
  • One side of the chimney is open to a plenum chamber from which air under pressure is cross-directed into the path of the filaments. The filaments are cooled by the airstream, and the air is then exhausted through an open side of the chimney.
  • heat from the filaments is transferred by convective circulation of air and depends on the film coefficient and the temperature difference between the filament surface and the ambient gas.
  • a further object is to produce special bumpy filament yarns.
  • an elongated, tapered tube is adapted to be uprightly positioned beneath a spinneret to receive freshly spun molten filaments issuing therefrom.
  • the tapered tube is adapted byjoining an air manifold and an air induction means therewith to effect a fluidized bed of fine particles in the path of the filaments as they pass through the tube.
  • the air ,manifold means provides an airstream in the tube which flows counter to the direction of the filaments and the air induction means provides a source of fine particles which are entrained within the airstream.
  • inert type particles the particles contact the filaments and absorb the heat therefrom, thus promoting cooling of the filaments.
  • fine inert particles of harder structure than the spun filaments the filaments are impinged upon and are dented so that the resulting filaments are pitted or pockmarked.
  • fusible type fine particle the particles fuse to the filaments and provide a novel nubby yarn.
  • FIGURE 1 is an elevation view with parts cut away showing the novel quench apparatus and method
  • FIGURE 2 is a cross section view taken through 22 of FIGURE 1,
  • FIGURE 3 is an elevation view showing a nubby type novel yarn of the invention.
  • FIGURE 4 is an elevation view showing a pockmarked type of novelty yarn of the invention.

  • the sections 3, 4, and 5 are sealingly and clampingly connected therebetween by means of flanges 6 provided at the joining ends of the sections, gaskets 7, and bolts and nuts S.
  • Upper section 3 is relatively short in length and has a wide funnelform mouth at its top and extends downwardly therefrom at a high degree of taper to join with intermediate section 4.
  • a spinneret 9 for extruding filaments 10 of thermoplastic material is positioned adjacent the funnelform mouth of section 3.
  • Section 4 is the longest section and has a constantly decreasing degree of taper from its upper to lower end where it joins with section 5.
  • Section 5 is substantially of the same width along most of its length. Section 5 extends from the lower end of section 4 for a distance and then is provided with a flared portion that terminates at its lower end in a cylindrical portion having a flange 11 formed about its outer periphery inwardly from the end thereof.
  • An air manifold 12 having a pressure chamber 13 defined therein is sealingly and clampingly connected to the flange 11 surrounding the cylindrical portion of section 5 by a gasket 14 and bolts 15.
  • the cylindrical portion of section 5 depends into the pressure chamber 13 and has a space defined therearound.
  • Manifold 12 has a chimney or sleeve member 16 of a smaller diameter than tube 1 which is coaxially arranged therewith.
  • Manifold 12 extends upwardly into section 5 and defines an annular space 17 between chimney 16 and the wall of section 5.
  • chimney 16 is tapered so that it gets progressively wider as it extends into section 5.
  • a smooth surfaced collar is provided at the inner end of chimney 16 to prevent damage to filaments that normally enter the chimney.
  • Annular space 17 permits communication between chamber 13 in manifold 12 and chamber 2 of tube 1.
  • a gas such as air under pressure from a source thereof, is normally delivered to pressure chamber 13 of manifold 12 by lines 18 adapted to be connected to suitable connectors press-fitted in ports provided in manifold 12.
