Definitions

  • This invention relates to an apparatus for spinning synthetic filament yarns and to special filament yarns produced therefrom. More particularly, this invention relates to a novel apparatus for quenching thermoplastic filaments and to special bumpy filament yarns produced therefrom.
  • 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 coeflicient and the temperature difference between the filament surface and the ambient gas.
  • 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 by joining 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 2-2 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 pockm'arked type of novelty yarn of the invention.
  • a preferred construction of the novel spinning apparatus embodying the invention comprises an elongated vertically positioned tapered tube or vessel 1 having an axial chamber 2 extending thereth-rough.
  • Tube 1 can be of integral construction but, preferably, is constructed in three sections: an upper section 3, an intermediate section 4, and a lower section 5.
  • 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 8.
  • 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 is tapered. The smaller end of section 4 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 pressurechamber 13 defined t-herein 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 Band 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 extend-s into section 5.
  • a smooth surfaced collar is provided at the inner end of chimney 16 to prevent d-amage 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.
  • Drain plug 19 is provided in manifold 12 to permit removal of particles which settle therein.
  • Support members 20 are affixed to tube 1 at opposite sides thereof by suitable bracket 21 and bolt and nut assemblies.
  • Support members 20 are mounted on respective fixed clamp-s 22 which extend through the slots of support members 20 and which provide vertical adjustment of tube 1 to permit access to spinneret 9.
  • covered aperture or window 23 is rovided in section 4 of tube 1.
  • An induction device 25 is provided to introduce fine particles or other particulate matter into annular space 17.

  • Duct 30 is connected at its one end to an air inlet fitting fixed to the lower end of section and opening into annular space 17 and at its opposite end the duct is connected and open to mixing chamber 27.
  • a recirculating pipe 31 is connected at one end to an adapter mounted in an inlet port formed at the upper end of section 3; and at its opposite end the recirculating pipe is connected to an adapter mounted in an inlet port formed in section 5.
  • the recirculating pipe 31 is provided to stabilize the level of the bed and to collect fluidized particles which become disengaged from the bed and to return them to space 17.
  • Filaments 10 after passing through tube 1, are directed through a convergence guide 32 which converges the filament bundle for forming a yarn 33.
  • Yarn 33 is then advanced through a pigtail guide 34 and thence through a traverse guide 35 before being collected on a bobbin 36 of a take-up device 37.
  • tube 1 is adjusted by clamps 22 to be axially aligned with spinneret 9, with the top end of tube 1 approximately two feet below the spinneret 9.
  • a polyrner compound such as nylon for forming filaments is pumped through spinneret 9 and a bundle of filaments are extruded therefrom.
  • a vacuum device such as an aspirator gun inserted within chimney 16
  • filaments 10 are pulled downwardly through chamber 2 of tube 1 and through chimney 16.
  • Filaments 10 are then threaded through the convergence guide 32, advanced through pigtail guide 34, forwarded to the traverse guide 35 and then laid on driven bobbin 36 of the take-up device 37. Air under pressure is then delivered to pressure chamber 13 of manifold 12through lines 18.
  • the particles move at random within the bed and consequently collide or impinge upon the filaments 10 traveling therethrough.
  • the differential in temperaturethe filaments being relatively hot and the particles having a lower temperature-causes heat from the filaments to be transferred to the particles thus promoting cooling of the filaments.
  • the particles having gained heat from the filaments then transfer the heat one to another and to the airstream as well as to the walls of tube 1 upon contact therewith.
  • a high rate of heat trans e results from The large particle surface availa-ble ror fluidsolid contact.
  • the temperature within the bed remains substantially uniform.
  • nubby filament yarn 39 As shown in FIGURE 3, fine particles such as polyethylene powder or powdered sugar of fusible characteristic are used to establish the fluidized bed. Under this condition, the particles partially fuse to the filaments and when the filaments are cooled a nubby type yarn is produced.
  • Various effects and profiles can be provided by using particles of different shapes: spheroidal, cubical, cylindrical, etc. Dissolution of soluble particles adhering to the filaments (such as sugar) have irregular craters in the yarn surface, resulting in yarn illustrated in FIG- URE 4.
  • Aerosol fogs of water, inorganic, or organic liquids may be generated and delivered to the quench tube 1.
  • Highly volatile liquid droplets provide great heat absorption capacity.
  • Localized surface nubs are formed at the point of droplet impingement upon the still molten filament to yield a pimpled or wart-like surface. 7
