Description
Verfahren zum Auswaschen von Fällbadrückständen aus gespulter Kunstseide. 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 sechs bis acht Tage, je nach Art -der Spule, der Wicklung und der Menge des Fasergutes. Durch die lange Einwirkung des Wassers büßte der fertige Faden an Festigkeit ein. Nach dein zweiten Zerfahren erfolgt das Waschen durch systematisches Berieseln. Auch dies erfüllt die Hoffnungen nicht vollständig, weil es stets vorkommt, daß man auf unvollständig ausgewaschene Spulen stößt, die beim Trocknen Schaden leiden. Die Einwirkung des Wassers auf die Spulen ist oft nicht gleichmäßig. Nach diesem Verfahren kann im großen überdies 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 Copsbleicherei und -färber'ei. Hier wird zwar an Waschzeit gespart, doch sind Unregelmäßigkeiten im Waschen und damit Schädigungen der Spulen schwer zu vermeiden. Wenn auch der Wasserdruck des zugeführten Waschwassers überall gleich ist, so sind doch die Spulen nicht gleich dicht gewickelt und bieten dem Wasser verschiedenen Widerstand.Process for washing out precipitation bath residues from spooled rayon. The spooled rayon is used to remove the precipitation bath until it reacts neutral washed. So far, this has been done using three procedures. After the first one set the Coil in running or occasionally refreshed water. Such a washing requires six to eight days, depending on the type of coil, the winding and the amount of the fiber material. Due to the long exposure to the water, the finished thread lost Firmness one. After your second disintegration, the washing is done systematically Sprinkle. This also does not completely fulfill hopes, because it always happens that you come across incompletely washed out bobbins that damage when drying To suffer. The action of the water on the coils is often not uniform. To Moreover, this process can only be used with a very large excess Water and washing time spent, a satisfactory result can be obtained. The third method is the so-called pressurized watering, which is based on the same principle like the bobbin and cop bleaching and dyeing works. Here is washing time saved, but there are irregularities in washing and thus damage to the bobbins difficult to avoid. Even if the water pressure of the washing water supplied is everywhere is the same, the coils are not equally tightly wound and offer that Water different resistance.
Die genannten Übelstände lassen sich dadurch beseitigen, daß man die Druckwässerung oder 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 verlangt noch, je nach der Gründlichkeit der Vorwaschung, 1a bis 48 Stunden Zeit. Man erreicht bei kürzerer Waschzeit dadurch ein völlig gleichmäßiges Auswaschen, und es ist jegliche Schädigung des Fadens ausgeschlossen. Man kann den Wasserverbrauch verringern, indem das Wasser der Nachwaschung, die natürlich auch warm erfolgen kann, für die Vorwaschung verwendet wird. Man braucht bei ordnungsmäßigem Arbeiten derart wenig Waschwasser, daß man darin die Säure so anreichern kann, daß dieses saure Wasser zur Bereitung des Fällbades mit Vorteil zu verwenden ist.The abovementioned evils can be eliminated by the Pressurized watering or sprinkling with washing in flowing or intermittent renewed water. One subjects the bobbins on suitable transportable ones Attachment devices for a pre-wash by sprinkling or by pumping through Water and then puts the whole rack in vats, where you can run with the help of or periodically changing water to complete the washing. This post-wash still requires 1 to 48 hours of time, depending on the thoroughness of the pre-wash. A completely even washout is achieved with a shorter washing time, and any damage to the thread is excluded. You can see the water usage decrease by the water of the post-wash, which of course also take place warm can be used for pre-washing. You need to work properly so little washing water that the acid can be so enriched that this acidic water is to be used with advantage to prepare the precipitation bath.
