Definitions

  • the invention relates to the production of artificial silk, for example copper oxide ammonia silk by the stretch spinning process.
  • This process has been carried out previously by using the collecting device for the spun thread, for example, a reel or a bobbin, at the same time as the device for giving the required tension to the thread during the spinning process, that is to say, the collecting device was at the same time a drawing device.
  • the thread was laid upon the bobbin or reel employed under considerable tension, which rendered necessary, particularly in the case of reels, a relatively heavy construction, since a considerable mechanical stress is produced by the silk wound on the reel in many turns.
  • the thread is previously formed in a stretch spinning apparatus, is then subjected to a considerable stretching by a suitable drawing device, and. is conducted from the latter drawing device to the winding-on device under adjustable tension or without tension.
  • This process not only avoids the disadvantages described, but has the advantage that the resistance of the thread can be considerably increased by the second stretching of the thread outside the spinning funnel.
  • Apparatus of various kinds may be used to carry out the process according to the invention.
  • a drawing device rotating at a higher speed introduced in front of the device for collecting the thread, whether the latter is a bobbin or reel.
  • the drawing device consists as a rule of a roller more or less encircled by the thread.
  • Fig. 1 is a diagrammatic side elevation of one form of the invention
  • Fig. 2 is a view similar form of the invention
  • Fig. 3 is a form of the invention similar to that shown in Fig. 1 with a reel being substituted for the spool shown in Fig. 1.
  • l is a spinning device of the usual kind.
  • the thread first travels from this around a guide rod 3, then through an acid treatment channelled member 4, over a drawing roller 5 and finally through a thread conductor 6 to the winding-on bobbin 1.
  • the thread encircles the to Fig. 1 of a modified roller 5 and then runs through the thread guide which is moved backwards and forwards in the direction of the double-headed arrow I, then on to the bobbin 1.
  • the angle through which the thread is wound round the roller 5, the adhesion ratio, as well as the material of the roller 5, are so selected that as far as possible the thread does not slip upon the roller 5.
  • a further drawing roller 8 is provided in front of the drawing roller 5, and a spout 9 is provided in place of the acid treatment channelled member 4 in front of the roller 5.
  • the spout 9 conducts acidifying liquid on to the roller 5.
  • a channelled member I is disposed below the roller in order to catch the acidifying liquid.
  • the bobbin 1 and the thread conductor 6 are, in this case, arranged below the roller 5. In this arrangement, stretching again takes place between the rollers 8 and 5 to an extent determined by the speed of the rollers.
  • a process for the production of artificial thread comprising forming the thread preliminarily by the cuprammonium stretch spinning process in a stream of precipitating liquid, then subjecting the thread to a considerable stretching, and winding the thread upon a rigid winding device under reduced tension.
  • a process for the production of artificial thread comprising forming the thread preliminarily by the cuprammonium stretch spinning process in a stream of precipitating liquid, then subjecting t e thread to a considerable stretching and app ying a setting solution to the thread while under tension, and winding the thread upon a rigid winding device under reduced tenslon.
  • a process for the production of artificial thread comprising forming the thread preliminarily by the copper oxide ammonia stretch spinning process in a stream of precipitating liquid,
  • a process for the production of artificial thread from cellulosic solutions comprising forming the thread by the stretch spinning process in a stream of precipitating liquid, then subjecting the thread to a further considerable stretching by drawing it without substantial slippage upon a drawing rollerrotating at a regulated speed, and thereafter collecting the thread upon a rigid receiver upon which the thread is wound from the interior outwardly, said receiver being rotated so as to have a slower peripheral speed than that of the drawing roller.
  • a process for the productionof artificial thread comprising extruding the filaments and subjecting them while plastic to a considerable stretching, applying a iixing solution to the illsments whileunder tension and thereafter wind- :18 them upon a rigid holder under reduced ten- 7.
