Definitions

  • This invention relates to apparatus for the manufacture of artificial filaments or fibers, and more particularly for the manufacture of such filaments or fibers by the dry or evaporative method, i. e., by the extrusion of spinning solutions comprising a volatile solvent through jets or nozzles into an evaporative atmosphere which effects the removal of the volatile solvent from the extruded filaments.
  • the part of a spinning jet or nozzle which is exposed to the evaporative medium is formed or provided around the or each spinning orifice with a matt surface.
  • the Whole or substantially the whole of the surface of the disc may be matt or unpolished, all the spinning orifices lying within the matt or unpolished area.
  • the area surrounding the orifices in other types of jets or nozzles may according to the invention have a matt surfaces, and the orifices of single orifice jets or nozzles may be surrounded by a similar surface.
  • Figure 1 is a vertical section through the jet
  • Figure 2 is a perspective View of the jet shown in Figure 1.
  • the jet shown consists of a dished member 3 having a flange 4.
  • Spinning orifices 5 are formed by perforating the base 6 of the dish 3, the drawing showing a circle of such orifices.
  • the outer face 7 is given a matt surface by any of the methods herein indicated, this matt surface being indicated conventionally by double cross-hatching in Fig. 2.
  • the rate of transfer of heat from the evaporative medium into which the filaments are spun to the spinning solution in the jets or nozzles is increased to some extent when the jets or nozzles are formed with matt surfaces.
  • the jets or nozzles are useful in the dry-spinning of solutions of cellulose acetate or other cellulose derivatives.
  • the matt surface may be formed on the material of the jet or nozzle at any suitable stage of its manufacture, and either before or after the provision of the spinning orifice or orifices in the jet or nozzle.
  • disc-type nozzles of the character above referred to may be formed from sheet material having the requisite surface, or the material of the disc may be treated to give it the matt surface prior to or after the formation of the orifices.
  • Various methods of surfacing the material of the jet or nozzle may be resorted to, sand blasting or etching having been found particularly suitable.
  • the jets or nozzles, or the material from which they are made may be etched with suitable acids or acid mixtures.
  • a spinning jet for the manufacture of artificial filaments by the evaporative method characterized in that the part of the jet which is exposed to the evaporative medium is provided around each spinning orifice with a matt surface.
  • a disc-type spinning jet for the manufacture of artificial filaments by the evaporative method characterized in that the part of the jet which is exposed to the evaporative medium is provided around each spinning orifice with a matt surface.
