Definitions

  • This invention relates to the manufacture of artificial silk and particularly to the process known as dry spinning.
  • artificial silk is manufactured by the extrusion of filaments or threads of cellulose acetate or other cellulose derivatives through nozzles into a chamber in which a stream of air or any other suitable gas heated to a suitable temperature serves to dry the threads and carry away the evaporated solvent.
  • the present invention consists of artificial silk manufacturing apparatus in which the extruded threads are subjected to the action of a current of air while passing through a drying chamber, wherein the current of air is passed through the drying chamber in the same direction as that in which the extruded filaments are moving.
  • Means may be provided whereby the velocity of the current of air leaving the drying chamber will be greater than that entering it, and this increase in velocity may be arranged to be gradual.
  • the current of air and the threads may be arranged to pass through a conical tube or other tube of gradually decreasing cross sectional area.
  • the main drying chamber having an insulating jacket 26, and in the centre of which is provided a tube 3 through which the threads 5 extruded from the jet nozzle 4 pass downwards together with a stream of air or gas.
  • the tube 3 is of conical shape so as to ensure constant acceleration of the stream of air or gas passing through it. I l n
  • the tube 3 has an enlarged open upper end 3a to admit air passed from an inlet 2a'up. through a heating device 6 and the annular space between the vessel 2 and the tube 3, and is-provided with radiating ribs 36.
  • the filaments 5 passunder a guide pulley 7 and through 'a lateral outlet 20 to any suitable collecting device.
  • the 35 stream carrying the plurality of threads 5 can be utilized to pass the filaments or threads through any suitable device of a rotary typeadapted to twist the threads together so that at the exit 20 from the cabinet the threads 00 appear as a single twisted thread ready for any other operations such as winding on bobbins or whatever is required in any specific case.
  • Apparatus for the manufacture of artificial silk by the dry spinnin process com prising a drying chamber, a lament extrusion nozzle within the upper portion of the chamber, a gas inlet in the lower end of the drying chamber, a gas outlet also in the lower end of the drying chamber, a central tube within the chamber, a heater for the gas in the drying chamber, the upper end of the tube being open to the gas space within the" chamber ,while the lower end of the tube forms an outlet for the filaments and the gas at the lower end of the chamber, the central tube being of gradually decreasing cross sectional area throughout its length, and the gas heater arranged on the outside of the central tube.
  • Apparatus for the manufacture of artificial silk by the dry spinning process comprising a drying chamber, a filament extrusionnozzle within the upper portion of the chamber, a gas inlet in the lower end of the drying chamber, a gas outlet also in the lower end of the drying chamber, a central tube within the chamber, a heater for the gas in the drying chamber, the upper end of the tube being open to the gas space within the chamber while the lower end of the tube forms an outlet for the filaments and thegas at the lower end of the chamber, the central tube being of gradually decreasing cross sectional area throughout its length, and the gas heater arranged at the lower end of the drying chamber.
  • Apparatus for the manufacture of artificial silk by dry spinning process comprising a drying chamber, an insulating jacket surrounding said drying chamber, a central tube within the chamber, a nozzle within the upper portion of the chamber for extruding V V filaments into said central tube, an inlet and outlet for the drying gas, means whereby the drying gas can be passed through said central tube in the direction of movement of the filaments, means within the chamber for heating the drying gas, a lateral outlet for the dried filaments near the lower end of the chamber, and a filament guiding pulley, the said central tube being of gradually decreasing cross sectional area throughout its length and the pulley arranged at its lower end so that the dried filaments can pass through the lateral outlet, while the drying gas passes through the gas outlet, independent of the filament outlet. 7
