Definitions

  • cop hydroxide deposits are separated of! in t a spinning device,more particularly at 5 the outflow pipe of the 'spmnin'g nozzle. These deposits offer a resistance to the bunchof threads drawn through, which may easily cause threads to break. Hitherto it has been necessary temporarily'to stop the machine or at least the separate spinnin'g-devicesun order to clean the pipe.
  • this cleaning may beeflected during working without it being necessary to interrupt the spinning operation and consequently break the thread.
  • a cleaning fluid is caused to flow at a suitable point into the spinningnozzle' or at the tapered'lower outlet-of the same, which fluid dissolves the copper. hydroxide.
  • suitable cleaning fluid is a dilute acid, .for
  • a spinning device suitable for carrying out the cleamng method'just described may be constructed in such a manner that the spinning nozzle is connected by a se' arate pipe at a suitable point to the vessel or the cleaning fluid.
  • the requisite excess pressure of the dim fluid may be obtamed by placing the said vessel in an elevated position. It ma also be obtained by raising the vessel only or the period, during whichthe cleaning fluid is to flow through. This ren-' ders cocks in the supply pipe superfluous.
  • the vessel may on the other hand he placed 7 so low that only as-much fluid can be withdrawn at a'time as has been poured into the vessel above atititain level.
  • A'vessel b, Fi'. 3 is fixed in'such a manner that, when a ut halffull of acid, the level of the fluid bis the.same as the level in the vessel w.
  • the said acid will at once flow through a, as the levelin is raised, owing to the addition of fresh acid.
  • the level in b immediately assumes the same level as that in w and the flow of acid'cease's.
  • the pipe a is introduced laterally into the pipe 8, which. enters above the tapered part 6 of the nozzle, This pipe can of course be connected at any other On the cock lb being opened the cleaning fluid will flow in, will mix with-the precipitating fluid and will efparts of the formed.
  • the spinning device shown in Fig. 5 shows a tapered nozzle within a cylindrical part F.
  • the precipitating fluid enters through a pipe (1 at the bottom of the cylindrical part, rises in the latter and falls into the tapered part e.
  • This s inning device has already been described, or instance in German Patent 220,051.
  • the cleaning fluid is supplied through a pipe (2 having a cock h in such a manner that the two fluids are already. mixed before enter- In this case as well the pipe may be connected elsewhere.
  • That method of cleaning spinning devices employed in the manufacture'of artificial silk threads from copper oxide ammonia cellulose solutions without necessarily interrupting the passage of the threads through said device which consistsin introducing dilute sulphuric acid into the spinbination of a spinning nozzle; means for introducing a setting fluid for the threads into said nozzle; a vessel located exteriorly of the nozzle and adaptedto containa cleaning fluid; and aflexiblepipe connecting said vessel with the spinning nozzle whereby when the vessel is elevated liquid may flow 'from'said vessel into the nozzle and when lowered such flow will be cut ofi.
