Definitions

  • Fig. 1 is an elevation partly in section of one apparatus and Fig. 2 is a similar illustration of a modified arrangement according to the invention.
  • a perforated bobbin 2 upon which is wound the artificial silk arn or thread 3, is placed in a receptacle 1.
  • e bobbin is closed at the top end in a water-tight manner by means of a plug 4, and is closed in a similar manner at the bottom by another plug 5 having a discharge opening so that the washing liquid which enters the washing receptacle at 6 can leave the receptacle through the discharge conduit 7 only by pass- I ing through the yarn or threads 3, the perforated bobbin and the lower plug 5 through which the discharge conduit passes.
  • a number of bobbins 2 2 2 2, arranged side by side and above each other, may be washed at the same time. All the bobbins are placed in the same receptacle 1. The bobbins are closed at their upper ends by plugs 4 4 The plugs 4 4 inserted between two bobbins arranged above each other are double plugs and are provided with internal bores or ducts 8 through which the washing liquid may pass in a downward direction.
  • the lower bobbins are closed at the lower ends by plugs 5 5 having ducts 7 and 7 2 opening into the common discharge conduit 7.
  • the perforated bobbins carrying as usual the artificial silk are placed in the receptacle, which bobbins are closed at the ends by means of the plugs.
  • the receptacle is then filled with washing water orliquid until the bobbins are completely covered.
  • a vacuum or suction pump operating through the discharge conduit carries off the washing liquid by drawing it through the silk wound on the perforated bobbin into the hollow core and thus out. If a suction or vacuum corresponding to say 200 to 300 millimeters of mercury is used, a bobbin may be completely washed in about one hours time.
  • the admission of fresh washing liquid at 6 may be regulated in such a manner as to maintain a constant level of liquid in the receptacle dur ing the whole operation. This process does not in any way damage the yarn or threads and subjects them to a lesser strain than known processes.
  • the method forming the subject of the present invention not only provides a complete washing but also makes a great reduction in the time required for this and subsequent operations, such as the drying.
  • the elimination of the coagulation liquid or precipitation bath may be carried out without the necessity of a separate operation. It is sufiicient for this purpose to subject the bobbins placed in the washing receptacle in the manner above described to the action of a suction or vacuum before carrying out the washing operation as such, namely before the empty receptacle is filled with the washing liquid. In this manner a considerable quantity of the liquid of the precipitation bath adhering to the yarn or'threads may be rapidly and esaily removed. The precipitation liquid thus recovered may be again used in the manufacture, and the duration of the washing operation considerably reduced.
  • the above described method and a paratus has a great advantage in that it ena les several operations, such as the removal of-the precipitation or coagulation liquid, the washing of the product and the removal of the washing liquid, to be carried out in one operation, without a repeated handling of the bobbins and without any risk of damaging the yarn or threads.
  • a process for rapidly washing artificial fibers wound upon perforated bobbins or the like, and disposed in a tank which consists in first, causing the liquid residues of the coagulatmg bath or the like to be drawn inwardlv through the material and the perforations (if the bobbins by suction produced within the bobb ns; secondly, filling the tank with washing liquid and causing the washing liquid to pass once only through the material and the perforations of the bobbins by a continuation of the suction within the bobbins; and thirdly, cutt ng-off the supply of washingliquid and causing, by maintenance of the suction within the bobbins, the residue of the washing liquid to pass through the material and the perforations of the bobbins.
  • a process for rapidly washing artificial f bers, wound upon perforated bobbins or the l ke and disposed in a tank which consists in first, causing the liquid residues of the coagulating bath or the like to be drawn inwardlv through the wound fibers and the per foratioiis ot the bobbins by suction produced within the bobb ns; and secondly; filling the tank with washing liquid and causing the washing l quid to pass once only through the wound fibers and the perforations of the bobbins by iLfCOntlIlLlfltlOn of the suction within the bobins.
