Definitions

  • My invention relates to improvements in the method of and apparatus for manufacturing artificial silk, bands, plates and the like from viscose.
  • the object of the improvements is to provide a method by means of which minute cavities of uniform size are produced in the threads of the artificial silk, bands, plates and the like, and in which the size and number of the cavities can be exactly controlled.
  • my invention con sists in producing minute gas bubbles in the viscose by electrolysis, the said bubbles being generated by electrolytic decomposition of the soda lye resulting in oxyhydrogen or hydrogen.
  • the electrodes are locatcd immediately before the spinning nozzles, so that the viscose having the bubbles produced therein is immediately formed into threads, and there is no time for the bubbles
  • the intensity of the current the amount of the gas developed can be exactly controlled and adapted to the flow of the viscose and the character of the threads aimed at.
  • By providing electrodes in the form of points gas bubbles of minute and even size are produced. By being carried away by the viscose immediately after being formed the gas bubbles have not time to combine into bubbles of large and irregular size, which would result in an irregular thread. .7
  • Fig.' 1 is a sectional elevation of a nozzle
  • Fig. 2 is a top-plan view of Fig. l
  • Fig. 3 is a sectional elevationshowing a modification.
  • the spinning nozzle isiin the form of a cap A provided in its top wall with bores (l, as is known in theart. are two rings 6 and c insulated from each other by a ring e of a suitable insulating medium, and each ring carries a plurality of points f one for each of'the bores 01, and the said points are directed upwardly and towards the bores d.
  • the rings 6 and 0 are connected by leads 9 to a suitable source of electric current.
  • the electrodes are in the form 'of foraminated plates or wire gauze located one behind the other in thedirection of the flow of the viscous matter and stretched across the path of the viscous matter which is therefore forced to flow through the interstices of the gauze.
  • the pipe m supplying the viscose to the nozzle a is formed with an enlarged portion comprising a cylinder h of glass, rubber or the like, the fora'ininated platesi and j being placed between the ends of the cylinder h and the adjacent parts of the pipe m.
  • the letter 70 indicates an insulating and packing medium for the electrodes 2', j.
  • the electrodes are connected by leads 9 to a source (if electric current.
  • the foraminated plate or gauze i is the cathode, while the gauze or plate j remote from the nozzle a is the anode, so that hydrogen is generated at the electrode *5 and oxygen at the plate j.
  • my invention is not limited to thus connecting the electrodes to the current supply.
  • the surface of the electrodes is considerably increased.
  • An apparatus for manufacturing artificial silk, bands, plates or the like comprising a spinning nozzle, means for supplying viscose to said nozzle, and means for causing electrolysis in the viscose prior to delivering the same through said nozzle.
  • An apparatus for manufacturing artificial silk, hands, plates or the like comprising a nozzle, means for supplying viscose to said nozzle, and electrodes disposed across the flow of viscose to said nozzle.
  • An apparatus for manufacturing artificial silk, liands, plates or the like comprising a nozzle, means for supplying viscose to said nozzle, and electrodes in the form of Wire gauze or foraminated plates.
