Definitions

  • a cellulose in suitable solvents usually either a cuprammonium solution or caustic alkalis and carbon bisulfide.
  • suitable solvents usually either a cuprammonium solution or caustic alkalis and carbon bisulfide.
  • the solution prepared by either of these methods, is forced through spin-'- ning nozzles into suitable precipitating baths, whereby a very sensitive thread is produced.
  • This thread is fully hardened by suitable agents during its subsequent handling.
  • the freshly spun thread is first wound on collecting devices, such as spools or reels, or into spinning centrifuges, whereby the hardening liquid is given a sufiicient length of time to act upon the thread.
  • the thread is then treated with liquids in different ways to dissolve and wash out the impurities -,originating from-the raw cellulose and solvents,
  • first quality yarn is always reduced and this reduction is due mostly to uncontrollable minor causes which result frequently in serious loss.
  • many suggestions have been made to use a continuous process for the manufacture of artificial threads from the cellulose. It has been suggested that the thread be led in a single operation from the spinning nozzle, through the different baths and over a drying device to a take-up spool. It has also been suggested that use be made of endless conveyors or bands.
  • the process forms an artificial thread of a quality not hitherto obtained.
  • the fineness of the thread is as good as pure silk; but surpasses the latter to a considerable extent, in regard to the formation of a filament of great length free from knots.
  • the thread is also especially uniform with respect to its denier and dyeing qualities.
  • the troublesome irregularities known as Barre-effect
  • the cause of which has unsuccessfully been searched for a long time do not arise.
  • the invention also comprises an apparatus for carrying out the process.
  • the apparatus consists of a spinning funnel of well known construction, one or more rollers associated with thread guide bars on which the wet treatment is carried' out, and, finally, of a heated roller for drying the thread. Thread guides and turnin means are placed between the different devices.
  • the end of the apparatus is provided with a reel
  • the roller may have the form of cylinders or may be tapered in stages or in a conical manner. In the two latter; cases it is possible to pro Jerusalem a shrinkage or a stretching of a thread in a simple manner, if desired.
  • the treating liquid may be applied in difierent ways, for example, the rollers may be rotated in troughs.
  • the thread may also be effectively and advantageously treated on the rollers by spraying, whereby the liquid flows along the entire surface of the cylinders, thus insuring an effective treatment.
  • the counter current principle may also be used by the use of a vertical, slightly inclined; arrangement of the rollers.' The rollers may also be perforated to insure-an easier treatment of the threads at all points.
  • Figure 1 shows an arrangement for the continuous manufacture of fine filaments formed by the-use of a spinning funnel
  • the thread I for example, is treated with a flowing precipitating liquid in the spinning funnel 2 and led over a thread guide 24 to a channel 3 which is fed by the pipe l-with some setting liquid, such as an acid.
  • some setting liquid such as an acid.
  • the thread After passing over the rod 24 the thread is placed in a helical path upon a rotating roller 5 and the different windings are placed in the hooks I2 of The roller 5 is journalled in bearings I, I by stub shafts 5, 6' and dips into a vessel. 8 fed with liquid, such as water, according to the counter current principle by means of the pipe 9.
  • the used liquid is drawn away by the overflow pipe III.
  • the arrows A and B indicate the counter current movement of the liquid.
  • the completely wet handled thread is next taken by means of guides 24' and 24" to a heated drying roll I3 rotating by means of shafts IS, IS in bearings I I, H.
  • the temperature of the roller is kept constant by the use of hot steam, gas flames or by axially fed circulating hot oil as illustrated by numeral l3.
  • the different thread windings are again placed in hooks I5 of the guide bar I4.
  • the thread After the thread is dried to the desired degree, it is led to the spool I8 by means of a thread guide I9 which moves in the usual manner, and is wound upon said spool I8 or some analogous collecting device.
  • the thread also of the the filament type, namely of about 2 deniers, is placed in a helical path on a roller 5 supported at one end by a shaft 6 in bearings I, 'I'.
  • the roller is so shaped as to equalize the shrinkage of the thread.
  • the thread becomes stretched, this being sometimes desirable.
  • Hooks I! provided on the guide bar II again insure the uniform winding of the thread.
  • the liquid treatment (water, desulphurizing baths and the like) is carried out by spraying the rollers 5 from above, from several pipes 26 and 26', having small openings 21 and 21 formed therein for that purpose.
  • the number of the pipes and the length of the roller may be increased depending upon the desired treatment and the duration thereof.
  • the liquids flow over the surface of the roller into a vessel 8 in which they are accumulated.
  • Several separate rollers and a corresponding number .of receiving vessels may also be used in case it is advantageous to separately collect the liquid.
  • the thread I is led from the roller 5 over an additional turning bar or guide 24 onto a heated cylinder I3 which is tapered by means of the collar I3, the shaft I6 of the roller being journalled in a bearing IT.
  • the helical path of the thread is obtained by the use of guide bars I4, l4 provided with hooks I5.
  • the thread is dried on the smaller surfaces of the drying cylinders I3, then led over a wet roll 20 in a container for liquid 2
  • the drying of the thread may also be performed so that the thread will-first pass from the larger to the smaller surfaces after being re-moistened between these surfaces. However, the drying may also be carried out in stages, that isthe thread dried on one surface about 50% and completely dried on the second surface.
  • the disk 20 rotates in the trough 2
  • the shaft 6 of the roller 5 is supported vertically or nearly vertically in the bearing 1.
  • the surface of'the roller -5 is .wet with treating liquids fed from the pipe which is located in such a manner that the liquids strike the roller tangentially.
  • thethread is led toward the flow of the liquid in accordancewith the counter current fiow principle.
  • the perforations in' the surfaces of the roller are advantageous because it permits the liquid to completely envelop the thread at all points, thereby insuring a more complete action of the liquid on the thread.
