Description

Verfahren und Einrichtung zur Erzeugung sogenannter Luft- oder Leichtseide aus Viskose Es ist bekannt, daß man beim Verspinnen schlecht entlüfteter Viskose Fäden erhält, welche mit Luftblasen durchsetzt sind, was im normalen Betrieb als Produktionsfehler gilt. Es ist ferner bekannt und durch Patente geschützt, daß man solche Fäden absichtlich erzeugen kann, indem man die Viskose mit Luft oder anderen Gasen emulgiert. Das Verfahren leidet aber an dem Übelstand, daß man die Luftmenge nicht dosieren kann, und daß es nicht gelingt, den Luftblasen gleiche Größe zu verleihen. Weiter ist bekannt, der Viskose Stoffe, z. B. Soda, zuzusetzen, welche bei der Umsetzung mit dem SpinnbadKohlensäure erzeugen. Auch dieses Verfahren liefert aber keine einwandfreie Ware, vielleicht, weil dieEntwicklung derKohlensäure nicht gleichmäßig genug erfolgt.Process and device for the production of so-called air or light silk from viscose It is known that poorly vented viscose is used when spinning Receives threads, which are interspersed with air bubbles, what in normal operation as Production error applies. It is also known and protected by patents that one Such threads can be created on purpose by touching the viscose with air or another Emulsified gases. However, the method suffers from the drawback that the amount of air is reduced can not dose, and that it is not possible to give the air bubbles the same size. It is also known that the viscose substances such. B. Soda, add which in the implementation generate carbonic acid with the spinning bath. However, this method also does not provide a flawless one Goods, maybe because the carbon dioxide is not evolving evenly enough.

Vorliegendes Verfahren vermeidet die beschriebenen Übelstände dadurch, daß es durch Elektrolyse der Natronlauge der Viskose Knallgas bzw. Wasserstoff unmittelbar vor dem Verspinnen erzeugt. Die entwickelte Grasmenge kann durch die Stromstärke genau geregelt und dem Viskosedurchfluß angepaßt werden. Durch spitzenförmige Ausbildung der Elektroden können die Gasblasen möglichst klein und von gleicher Größe gehalten werden. Da sie gleich nach ihrer Bildung von der strömenden Viskose mitgenommen werden, haben sie nicht Zeit, zu größeren Blasen zusammenzufallen und dadurch Ungleichmäßigkeiten im Faden hervorzurufen. Wenn man dafür sorgt, daß innerhalb der Düse ein gewisser Druck herrscht, sprengen die Gasblasen nach dem Verlassen der Düse die Wand des Fadens und dieser nimmt dadurch bandförmige Gestalt an. An der Anode wird nur wenig Sauerstoff entwickelt, da dieser zum größten Teil durch Oxydation der vorhandenen, Schwefelverbindungen verbraucht wird. Dües ist ein weiterer Vorteil des Verfahrens, da dadurch die beim Spinnen stets auftretende Schwefelwasserstoffentwickl'ung vermindert wird. Durch Verringerung der Stromdichte an der Anode kann man die Sauerstoffentwicklung vollständig verhindern.The present method avoids the abuses described by that by electrolysis of the caustic soda the viscose oxyhydrogen gas or hydrogen directly generated before spinning. The amount of grass developed can be determined by the strength of the current precisely regulated and adapted to the viscose flow. Through pointed training of the electrodes, the gas bubbles can be kept as small as possible and of the same size will. Because it was carried away by the flowing viscose as soon as it was formed they do not have time to collapse into larger bubbles and thus irregularities to evoke in the thread. If you make sure that there is a certain inside the nozzle If there is pressure, the gas bubbles burst the wall of the after leaving the nozzle Thread and this takes on a ribbon-like shape. Little is done at the anode Oxygen is developed, as this is largely due to the oxidation of the existing, Sulfur compounds is consumed. Dües is another advantage of the process, as this reduces the hydrogen sulfide evolution that always occurs during spinning will. By reducing the current density at the anode, one can reduce the evolution of oxygen completely prevent.

Beiliegende Zeichnung zeigt eine schematische Ausführungsform des Verfahrens. Die Düse ist mit a bezeichnet, b ist ein Ring, der die negativen, Elektrodenspitzen trägt, c ein weiterer Ring mit den positiven Elektrodenspitzen.The accompanying drawing shows a schematic embodiment of the method. The nozzle is denoted by a, b is a ring that carries the negative electrode tips, c another ring with the positive electrode tips.
