  Verfahren zum Entfernen von Fällbadrückständen jeglicher Art aus gespulter Kunstseide. 
 EMI1.1 
 
Die gespulte Kunstseide wird zur Entfernung des   Fällbades   bis zur neutralen Reaktion gewaschen. 



  Das geschah bisher nach drei Verfahren. Nach dem ersten setzte man die Spule in fliessendes oder von Zeit zu Zeit erneuertes Wasser. Ein solches Waschen erfordert 6-8 Tage, je nach Art der Spule, der Wicklung und der Menge des Fasergutes. Nach dem zweiten Verfahren erfolgt das Waschen durch systematisches Berieseln. Auch dies erfüllt die Hoffnungen nicht vollständig. Einerseits verlangt es viel Handarbeit und komplizierte Einrichtungen, indem die Spulen im Gegenstrom dem Wasserstrahl entgegengeführt werden müssen, aber auch dann kommt es stets vor, dass man auf unvollständig ausgewaschene Spulen stösst, die beim Trocknen Schaden leiden. Nach diesem Verfahren kann im grossen nur mit einem sehr grossen   Überschuss   an Wasser und aufgewendeter Waschzeit ein befriedigendes Ergebnis erhalten werden.

   Das dritte Verfahren ist die sogenannte Druckwässerung, die auf dem gleichen Prinzip beruht wie die   Spulen-und Copsbleieherei und-färberei. Auch   hier liegen Schwierigkeiten bei der Apparatur und der Arbeitsweise vor und es sind   Unregelmässigkeiten   im Waschen und damit   Schädigungen   der Spulen schwer zu vermeiden. 



   Die genannten Übelstände lassen sich dadurch beseitigen, dass man die   bruckwässerung   und die Berieselung mit dem Waschen in fliessendem oder zeitweise erneuertem Wasser vereinigt. Man unterzieht die Spulen auf geeigneten transportablen Aufsteckvorrichtungen einer Vorwäsche durch Berieseln oder durch Durchpumpen von Wasser und stellt dann das ganze Gestell in Bottiche, wo man mit Hilfe von fliessendem oder periodisch wechselndem Wasser die Waschung zu Ende führt. Diese Nachwaschung

  Process for removing precipitation bath residues of any kind from spooled rayon.
 EMI1.1
 
The spooled rayon is washed to remove the precipitation bath until it is neutral.



  So far, this has been done using three procedures. After the first, the coil was placed in running water or water that was refreshed from time to time. Such washing takes 6-8 days, depending on the type of bobbin, the winding and the amount of fiber. In the second method, washing is carried out by systematic sprinkling. This, too, does not fully meet hopes. On the one hand, it requires a lot of manual work and complicated equipment, in that the coils have to be guided in countercurrent to the water jet, but even then it always happens that one comes across incompletely washed out coils that suffer damage when drying. According to this method, a satisfactory result can be obtained on the whole only with a very large excess of water and the washing time used.

   The third method is the so-called pressurized washing, which is based on the same principle as the bobbin and cop lead mill and dye mill. Here, too, there are difficulties with the apparatus and the mode of operation, and irregularities in washing and thus damage to the bobbins are difficult to avoid.



   The abovementioned inconveniences can be eliminated by combining the pressure watering and sprinkling with washing in running or temporarily renewed water. The bobbins are subjected to a pre-wash by sprinkling or pumping through water on suitable portable attachments and then the entire frame is placed in vats, where the washing is completed with the help of running or periodically changing water. This post-wash
