Definitions

  • This invention relates to a process for treating with water vapor or steam products such as fibers,
  • Another object of my invention is the provision of a method of treating the extruded products under such conditions that the certainty of successful operation and improved results are assured.
  • Another object of 'my invention is to provide out in a particularly advantageous manner by causing the water vapor to act on the products while they are moving over at least one vertically arranged pair of horizontal rollers.
  • the steam or water vapor may be mixed with other vaporous or gaseous substances influencing the properties of the products, for example those having a hardening action, such as for instance ammonia, methanol, sulfur dioxide,
  • the steam or water vapor may be made to act on the products by directing a steam jet onto the prcducts, but the rollers over'which the products are passed according to my present invention may also be arranged in a room in which a damp and more or less warm atmosphere prevails, which is preferably obtained by blowing steam into the room. It is not necessary to obtain a high temperature by means of the water vapor since the favorable action is effected even at a temperature as low as approximately 40 C.
  • a salt solution such as one containing sodium sulfate in an amount of approximately 10-15% can be used as a bath in which the rollers revolve.
  • Fig. 1 is a diagrammatic side view of an em-. bodiment for carrying out the process according to the invention
  • FIG. 2 is a diagrammatic side view of a pair of rollers with another arrangement of the steaming device
  • Fig. 3 is a diagrammatic side view of a pair of bottom roller revolving in a bath
  • Fig. 4 is a diagrammatic front view of a pair of rollers around which the threads are conducted several times;
  • Fig. 5 is a diagrammatic side view of a curling device comprising a profiled top roller of the pair of rollers, which cooperates with a profiled third roller;
  • Fig. 6 is a diagrammatic side view of a curling device comprising a profiled top roller of the pair of rollers, which cooperates with a third rubber roller;
  • Fig. 7 is a diagrammatic front view of a pair of conical rollers for stretching the thread.
  • Fig. 8 is a diagrammatic front view of a pair of stepped rollers for stretching the thread.
  • Fig. 1 the protein solutionis ex truded into spinning paths 1 through series of spinnerettes 2, the single thread bundles being drawn away by drawing rollers 4.
  • Thegcombin'ed thread bundles 5 are passed over vertically arranged pairs of horizontal rollers 6 and the liquid dripping from the threads and the rollers is collected in baths 1..
  • Fig. 2 illustrates how the steam pipe 8 may be arranged between the rollers of one pair and Fig.
  • the threads may be wound around the rollers several times, which embodiment is illustrated by Fig. 4 in which the numerals indicate the same parts as in the Figures 1-3. In this case 'the threads may beseparated with the aid of thread guides or other means.
  • the products can be roller of the pair a profile roller cooperating with 2.
  • Fig. 5 shows how the top roller 6 speed than the preceding pair.
  • Fig. shows how the thread is passed several times around a pair of conical departing from the invention or rollers l0 and Fig. 8 illustrates how the same result may be obtained by using stepped rollers I 1.
  • The. process' which comprises extruding an alkaline protein solution into 'a coagulatingv bath, thereupon conducting the extruded product through a path comprising substantially vertical portions; and blowing steam onto said product as it is conducted through the saidpath.
  • curling device consisting of the profiled top roller 6 of the pair of rollers, which cooperates with a said path.
