Description

Verfahren zur Herstellung schlauchartiger Zellulosehäute aus Zelluloselösungen. Bei der Herstellung von Zelluloseschläuchen aus Zelluloselösungen muß auch die Innenwand von der Fällungsflüssigkeit bespült, koaguliert werden, damit sie nicht verklebt. In der Patentschrift 24.7¢r8 und der britischen Patentschrift 17495 (igi4.) finden sich Beschreibungen von Vorrichtungen, die hierzu dienen. Bei der Ausführung dieser Verfahren bewegt sich das Fällungsbad mit dem Schlauch zusammen fort. Um die weitere Bearbeitung der Schläuche zu erleichtern, erschien es erwünscht, das innere Fällungsibad nur eine kurze Strecke weit auf die Schlauchwände einwirken zu lassen.Process for the production of tubular cellulose skins from cellulose solutions. In the production of cellulose tubes from cellulose solutions, the inner wall must also be washed and coagulated with the precipitation liquid so that it does not stick together. In the patent specification 24.7 [r8] and the British patent specification 17495 (igi4.) There are descriptions of devices which are used for this purpose. When performing this process, the precipitation bath moves along with the hose. In order to facilitate the further processing of the tubes, it seemed desirable to allow the inner precipitation bath to act only a short distance on the tube walls.

Dies ließ sieh durch eine besondere Anordnung der Badzuführung ermöglichen, ohne die Schlauchwand zu beschädigen, und zwar dadurch, daß man durch eine besondere Röhrenanordnung dem eingeleiteten Bade wieder Gelegenheit gibt, rückläufig abzufließen.This was made possible by a special arrangement of the bath supply, without damaging the hose wall, namely that you go through a special Tube arrangement gives the introduced bathing opportunity again to flow backwards.

Man kann das Bad im gleichen Sinne wie die Abzugsrichtung des Schlauches eintreten lassen. Besser noch führt man es nach dem Gegenstromprinzip. Eine einfache Vorrichtung ist folgende, die durch beiliegende Zeichnung erläutert wird.You can use the bath in the same sense as the direction in which the hose is pulled let in. It is even better to run it according to the countercurrent principle. A simple one Device is as follows, which is explained by the accompanying drawing.

Eine ringförmige, in das äußere Fällungsbad (Spinnbadwanne 5) eintauchende Düse i dient in bekannter Weise als Mündung der Stoffzufuhr. Im Inneren der Zufuhrleitung 2 und Düse ist ein Glasrohr 3 angeordnet, das ein Stück über sie hinausragt. Durch das Glasrohr wird das Fällungsmittel für die innere Seite des Schlauches eingeführt, strömt infolge des Zusammenfallens des Schlauches auf dem Aufwickelorgan rückläufig entgegen dem Gangdes koagulierten Schlauches in dem Zwischenraum q. zwischen Glasrohr und Düseninnenwandung zurück und wird aus diesem abgeleitet. Der Schlauch wird hierbei koaguliert und nimmt weiterhin noch so viel Bad mit, daß ein Zusammenkleben nicht mehr stattfindet. Er ist aber praktisch innen leer und kann auf Walzen oder Trommeln aufgewickelt und leicht weiterbehandelt werden. Das Verfahren eignet sich für Röhrengebilde der verschiedensten Größenöffnungen.An annular, immersed in the outer precipitation bath (spinning bath tub 5) Nozzle i serves in a known manner as the mouth of the substance feed. Inside the supply line 2 and nozzle, a glass tube 3 is arranged, which protrudes a little over them. By the glass tube is used to introduce the precipitant for the inner side of the hose, flows backwards due to the collapse of the hose on the winding element against the passage of the coagulated tube in the space q. between glass tube and nozzle inner wall back and is derived from this. The hose is doing this coagulates and continues to take so much bath with him that sticking together does not occur more takes place. But it is practically empty inside and can be placed on rollers or drums wound up and easily treated further. The method is suitable for tubular structures of various size openings.
