Definitions

  • Our present invention relates to a process and apparatus for washing and after-treating practically endless, thick bundles of freshly coagulated artificial threads of high total titer and for feed- 5 ing them after washing, subsequently treating and drying in a finished form to a receiving apparatus.
  • the invention is based on the observation that 1 it is possible to free freshly spun bundles of threads from the adhering constituents of the precipitating bath; also to subject them to further treatment, to washing, to bleaching and to soaping in such a very short time, that the operation of washing and. the subsequent treatment may be performed in an uninterrupted mannerduring the passage of the fiber bundles from the spinning bath to the receiving device, this passage even beinga straight line.
  • the process consists, therefore, in conducting the freshly spun bundles of threads of high total titer through successively arranged baths for washing and other treatment, between which pressure rollers of rubber are arranged, which are so driven that the speed of the draft which they produce can be varied.
  • the fiber bundle is caused to pass through each bath at such a speed that it is placed under no tension, or only under a very low tension. Moreover, the liquids adhering to the fiber bundles,- are removed by the squeezing rollers, so that no bath can be diluted or contaminated by liquid or the preceding bath adhering to the bundle.
  • the collected bundles of threads are guided between squeezing rollers, or even in a single-operation, around a reel through a trough of 5 meter length filled with water of a temperature of about 60-80" C. if necessary, this washing is repeated; then the bundle which is now free from acid is again led between another pair of squeezing rollers and then. passes through a desulfurizing bath,
  • the bandpasses between a pair of squeezing rollers the speed of which can be regulated.
  • the bundle of threads is held continuously under the surface of the liquid by guiding de-- vices which may be of glass.
  • a particular surprising advantage of the invention resides in the fact, that in addition to mechanical treatment with liquids a chemical treating as a de-sulfurizing operation of the bundles of threads also is possible.
  • the after-treated fiber bundle is once more subjected to squeezing and may now, after passage through the drying apparatus, be wound up as an endless band or passed through a cutting machine for producing staple fiber.
  • FIG. 1 is a plan and Fig. 2 and elevation.
  • a represents the bundle of threads, I) a pair of squeezing rollers the speed of which can be regulated by any suitable means not shown, 0 a trough or the like for receiving the bath liquid.
  • d are guiding devices.
  • An apparatus for washing and subsequently chemically treating freshly produced bundles of artificial fibers of a total titer of the order of at least 60,000 deniers on their way between the coagulation bath and the collecting device which apparatus comprises a number of troughs, and a pair ofsqueezing rollers between each pair of adjacent troughs, before the first trough and behind the last trough, each pair of rollers being independently driven and independently controllable as to speed of rotation, whereby the bundle being treated may be moved through the respective troughs under no tension.
