Definitions

  • This invention relates to the conversion of viscose into artificial threads and the like, by protruding the viscose through a suitable nozzle into an acid precipitating bath.
  • the thread after leaving the precipitating bath is led over a rotating wheel, and thence practically vertically downwards onto or round a second rotating wheel, while water, or other liquid is allowed to act on the thread as it passes round the second wheel.
  • This action of the liquid on the thread may be brought about by allowing the lower part of the wheel to dip into a bath of the liquid, or the liquid may be allowed to drip onto the wheel or onto the thread as it reaches the wheel, or one or more of these methods may be employed simultaneously in order to ensure that the liquid will act on the thread, as it passes round the said second wheel.
  • the thread After leaving the second wheel, the thread may be led over a third such rotating wheel, and thence to the collecting device, such for example as a rotating box, or a revolving bobbin, or the thread may pass directly to such collecting device, without the interposition of a third rotating wheel.
  • the thread may also be treated with water or other liquid, in a manner similar to that already described in connection with the second rotating wheel.
  • the surface speed of the second wheel may be the same as, or greater than, that of the first wheel, and in the latter case the thread will be stretched between the two wheels. If by the action of the water or other liquid on the second wheel, or by any other means, a contraction of the thread takes place, it may be desirable to adjust the speed of the third wheel to less than the speed of the second wheel.
  • This invention is particularly suitable for use when producing threads from viscose, by spinning into a bath containing a large proportion of acid, for instance per cent or more of sulphuric acid, as described in the British s ecification of British Letters Patent No. 2 7 4521, or 45 per cent to 55 per cent of sulphuric acid as described in the British specification of British Letters Patent No.
  • A represents the nozzle dipping into the precipitating bath contained in the vessel B.
  • the viscose, issuing fromthe nozzle A takes the form of a thread A which is passed over a first wheel C, then Vertically downwards to a second wheel D,
  • the thread after passing round the wheel D, is taken to a third wheel F, and thence through a funnel G into a spinning box H.
  • the three wheels C, D and F are practically in one plane, while in Figure 2, the wheels D and F are in a plane which is at right angles to the plane of the wheel 0.
  • the thread after leaving the precipitating bath, in the vessel B, may pass lightly over a guide rod K, as shown in Figure 2. Care should be taken to ensure that the wheel exercises the necessaryy grip on the thread, for example, if the wheels are of small diameter, the threads can be passed once or more times round the wheels.
  • a spinning nozzle adapted to dip into a precipitating bath, a rotating wheel, practically on a horizontal level with the spinning bath, a second rotating wheel situated practically vertically below the first rotating wheel with means for causing fluid to act onthe thread under treatment and a collecting device for receiving the thread from the second rotating wheel.
  • a spinning nozzle adapted to dip into a precipitating bath, a rotating wheel practically on a horizontal level with the spinning bath, a second rotating wheel situated practically vertically below the first rotating wheel with means for causing fluid to act on the said thread, a third rotating wheel adapted to receive the thread from the second rotating wheel, and a collecting device to which the said. thread is finally passed.
  • apparatus for the production of artificial threads or the like from viscose as claimed in claim 4 including means for adjusting the speed of the third wheel to less than that of the second Wheel substantially as and for the purpose described.
