Definitions

  • This invention relates to a process of and apparatus for avoiding, as far as possible, variations of the titer of the individual threads spun from the nozzle in the dry spinning of artificial threads.
  • This invention minimizes these difficulties in spinning highly viscous solutions by guiding the spinning solution which enters the spinning cell into symmetrically placed streams and in as thin layers as possible along the surface of a body of hi h heat capacity placed directly above nozzle.
  • Apparatus for realizing the invention may be constructedin various ways.
  • FIG. 1-6 of the accompanying drawing illustrate some of these ways, Figsbl, 3 and 5 being axial sections and Figs. 2,; 4 and dcorresponding cross sections.
  • the same letters of reference indicate the same-parts in all 'the figures.
  • two bodies of the highest possible heat capacity are arranged one within the other in such a manner that between them there is a space as narrow as may be for the passage of liquid, the opposite faces of the two bodies having any desired form; for example, as in the case shown, the bodies may be co-axial cylinders.
  • the outer cylinder a of a diameter of, for instance, 5 cm. having comparatively thin walls of a thickness of, for instance, 0.4 cm. is furnished for the purpose of increasing its heat capacity, with external ribs 9.
  • the massive, inner cylinder 19 is fitted into the outer cylinder and has perforations h for entering of the solution into the narrow annular space of a thickness of, for instance, 0.3-0.5 cm. between the two cylinders, these separate streams all issuing through the nozzle connected to the end of the outer cylinder.
  • the spinning solution enters through the duct e fixed in the cover 0, this latter being screwed on to the cylinder with interposition of the washer d.
  • Figs. 3 and 4 The form shown in Figs. 3 and 4 is essentially the same as that already described, but the attempt has been made to provide a larger surface of contact for heat exchange with the outer and inner cylinders.
  • the inner cylinder is provided with 16 peripheral grooves of a diameter of, for instance, 0.3-0.5 cm. in the axial direction through which the solution flows, the cylinder otherwise fitting closely in the external cylinder (1.
  • the equalizing body consists of a single piece a through which the spinning solution flows by way of 9 bores of the diameter of, for instance, 0.3-0.5 cm. parallel with the axis. Since these bores are narrow in comparison with the mass of the body, the desired homogenizing of the spinning solution is obtained more or less in the same manner as in the other construction.
  • our invention is not limited to the special forms of the homogenizing device as described. Thus, for instance, they may be arranged in combination with a special heating or cooling device in order to heat or cool them at any desired temperature.
  • a device for equalizing the temperature of the spinning solution before leaving the nozzle comprising in combination a hollow heat conducting body provided with an inlet for the spinning solution, a massive heat conducting body placed in the said hollow body, filling up the latter nearly completely and causing the spinning solution to flow in form of a thin layer between the inner face of the hollow body'andthe outer face of the massive body, and an outlet on said hollow body bearing the spinning nozzle.
  • a device for equalizing the temperature of the spinning solution before leaving the nozzle comprising in combination a cylindrical heat conducting hollow body provided with heat capacity increasing ribs and an inlet for the spinning solution, a cylindrical heat conducting massive body, placed in the said hollow body,
  • a device for equalizing the temperature of the spinning solution before leaving the nozzle comprising in combination a cylindrical heat conducting hollow body provided with an inlet for the spinning solution, a cylindrical heat conducting massive body placed in the said hollow body filling up the latter nearly completely and causing the spinning solution to flow in form of a thin layer between the inner face of the hollow body and the outer face of the massive body, means for asserting the heat exchange arranged on the outer cylinder and an outlet on said hollow body bearing the spinning nozzle.
  • a device for equalizing the temperature of a spinning solution before leaving the nozzle which comprises a body of high heat capacity, placed in the path of the spinning solution directly above the nozzle, of such a character that the spinning solution flows finely distributed over a substantial distance across said body of high heat capacity.
