Definitions

  • Figure 1 shows a sectional o -view of an apparatus used for the process of the present invention.
  • Figure 2 shows a plan View of the rotating table on which the fiber material is laid.
  • Figure 3 is a sectional view of an apparatus 5 used for the process with means for imparting a to and fro movement to said apparatus.
  • the invention consists of a system for this purpose and may be described as follows:
  • the freshly precipitated bundle of fibers is guided over a roller or similar device and is laid'afte-r a short suspension path on a support which is rotating about a vertical or slightly inclined axis, advantageously a slowly rotating plate. It is of advantage to lay the bundle on the plate in a form which fills the plane as much as possible, for instance in a zigzag form, by moving it to and fro, or in a spiral formp In this manner it becomes possible tobring onto a plate of 1 meter to 1.2 meter diameter, rotating once per minute, meters or more of the band.
  • the fibers are still acid after the spinning, it generally suffices to retain them for a time corresponding with the 100 meters onthe rotating plate inorder that the decompo: sition of the residual 'xanth'ate may be complete.
  • the bundles of fibers is thenled, if desired with simultaneous pressure, over a further'roller onto a second, third, fourth and if necessary still furbe desirable the thread is subjected to the necày step of the treatment, the threads being ther rotating plates, on each of which as may simultaneously pressed once or more often on the rotary plate.
  • the plates may be perforated, in which case the fibers may easily be washed on the plate by slow sprinkling with water of the desired temperature.
  • the Washing process may be reinforced or accelerated by squeezing the fibers.
  • a suction device there may be arranged under the perforated rotary plate, particularly under the last part of it, a suction device. If the rotary plate is embedded in a closed casing, the cellulose wool may be subjected to a treatment with gas or vapor at any desirable stage.
  • the cylindrical hollow space thus provided may serve as a bath and the fibrous bundle may be laid in'this bath in the manner described above.
  • the liquid may be allowed to flow through the bath or if the fiber consumes a chemical in the operation such chemical may be introduced into the bath in a proportion to keep the strength thereof constant.
  • the process of the invention is applicable also to the treatment of cut fibers. These are laid upon the rotary plate by a depositing device and after treatment are removed by a lifting device and transported further.
  • the system is extraordinarily simple. It requires, for example, a space of 10 meters long,
  • Figure 3 shows a device in which the whole rotating support is moved toand fro.
  • the device shown in Figures 1 and 2 is arranged on a chassis ch supported on the wheels 1/ and moving on the rail .r.
  • the device is only partly shown in Figure 3, the bell H and part of the SupDQrt C being shown.
  • the rest of the mechanism is the same as in Figure 1.
  • the motor m serves to drive therotating plate by means of the cogged wheels :22.
  • the whole arrangement is moved to and fro inthe direction of the arrows by the wheel 1071 which is connected therewith by the rod r1 which is connected to the turning points 113 and 274.
  • annular ring is separated from the plate on which the fiber bundle is laid and on which a series of rollers W are acting. Between the rollers the sprays D are located.
  • the fiber material is impregnated by the sprays with the treating liquids and squeezed by the rollers which are driven by adhesion to the rotating plate. Behind each roller when looking in direction of the arrow a spray may be arranged which on this side moistens the roller and thereby prevents a sticking of the squeezed dried material to the roller.
  • the squeezed-off treating liquid runs either through the perforations 0 arranged at the side of the rollers, or in the case the plate is perforated in sieve-like manner, through the perforations d into the receiving device, for instance F.
  • the treating liquid may also besucked off by means of a suction device G as it is shown on the right-hand side of the drawing.
  • a suction device G is arranged for each treating or washing liquid beneath the corresponding spot of the rotating plate.
  • the spraying devices are The washing liquids, for instance Water or different treating liquids are circulated through the spraying devices. may be after-treated on this apparatus if a cutting device is arranged before E.
  • the Whole rotating plate maybe put into a bell H which at J is connected with a suction device so that detrimental gases may be removed. Gases or vapors may be introduced through the opening K so that also an after-treatment of the fiber with these latter may be carried out.
  • the bell H has only been shown in a diagrammatic manner.
  • a device for the continuous treatment of threads which comprises a plate rotating about a substantially vertical axis, means for laying the threads onto said plate in zig-zag form, means for impregnating the threads with treating agents, means for removing said treating agents, and means for continuously withdrawing said threads from said plate.
  • a device for the continuous treatment of Instead of fiber bundles also cut staples threads which comprises a plate rotating about a substantially vertical axis, means for laying the threads onto said plate in zig-zag form, means for impregnating the threads with treating liquids on said plate, means for removing said treating liquids, and means for continuously withdrawing said threads from said plate.
  • a device for the continuous treatment of threads which comprises a plate rotating about a substantially vertical axis, means for laying the threads onto said plate in zig-zag form, means for impregnating the threads with treating gases on said plate, means for removing said treating gases, and means for continuously withdrawing said threads from said plate.
