Description

Verfahren zur Herstellung von Viscosekunstseide Es ist bereits bekannt, die Ziehfestigkeit von Viscose durch Zusatz von Türkisclirotöl oder anderer sulfurierter Öle zu verbessern (E. Patent 340 56¢). Diese Zusätze erleichtern das Filtrieren und besonders das Verspinnen der Viscose, namentlich auch bei der Herstellung feinfädiger Seide, und ermöglichen die Anwendung hoher Abzugsgeschwindigkeiten an der Spinnmaschine.Process for the production of viscose rayon It is already known the tensile strength of viscose through the addition of turquoise blue oil or other sulfurized To improve oils (E. Patent 340 56 ¢). These additives make filtering easier and especially the spinning of the viscose, especially in the production of fine threads Silk, and enable the use of high take-up speeds on the spinning machine.

Es wurde nun gefunden, daß diese Vorteile auch erreicht werden können, wenn man der Viscose Cholansäure oder deren Derivate zusetzt. Diese Stoffe besitzen die Eigenschaft, wasserunlösliche Körper in Wasser oder Alkalien in Lösung zu bringen. An Stelle der genahnten Monocarbonsäuren selbst können auch Salze oder Kondensationsprodukte derselben Verwendung finden.It has now been found that these advantages can also be achieved when cholanic acid or its derivatives are added to the viscose. These substances own the ability to dissolve water-insoluble bodies in water or alkalis. Instead of the aforementioned monocarboxylic acids themselves, salts or condensation products can also be used find the same use.

Der technische Vorteil dieser Zusätze besteht darin, daß bereits sehr geringe Mengen der genannten Stoffe ausreichen, die Viscose in spinntechnischer Beziehung bedeutend zu verbessern. So wird zum Beispiel bereits mit 0,02 % cholsaurem Natrium, auf die Viscose berechnet, ein erheblicher Effekt in dem angegebenen Sinne erzielt, selbst wenn nicht die reinen Körper, sondern die viel billigeren Rohprodukte Anwendung finden, wie z. B. die ,unter dem Handelsnamen Fel tauri bekannten Produkte. Der Zusatz der genannten Stoffe zur Viscose erfolgt zweckmäßig gleichzeitig mit dem Lösen des Xanthates, jedoch können dieselben auch bereits dem Xanthat selbst oder der Löselauge oder schließlich der fertigen Viscose in irgendeinem Stadium zugesetzt werden.The technical advantage of these additives is that they are already very Small amounts of the substances mentioned are sufficient to make the viscose in spinning technology Significantly improve relationship. For example, 0.02% is cholic acid Sodium, calculated on the viscose, has a considerable effect in the sense indicated achieved, even if not the pure body, but the much cheaper raw products Find application such. B. the products known under the trade name Fel tauri. The substances mentioned are expediently added to the viscose at the same time dissolving the xanthate, but the same can also be done with the xanthate itself or the dissolving liquor or finally the finished viscose at some stage can be added.

Es wurde ferner gefunden, daß man Kunstseide von besonders hoher Festigkeit erhält, wenn man die mit den angegebenen Zusätzen versehene Viscose unter erhöhter Streckung verspinnt.It has also been found that rayon of particularly high strength can be used obtained when the viscose provided with the specified additives is increased Stretching spun.

So erhält man beispielsweise durch Verspinnen der erwähnten 0,02 'lo cholsaures Natrium enthaltenden Viscose in normale Spinnbäder (Müllerbäder) Fäden mit einer Festigkeit von 2,4 g/den. und einer Dehnung von 18 010, wenn man mit 50 0j0 Streckung spinnt.For example, by spinning the mentioned 0.02 'lo Viscose containing sodium cholic acid in normal spinning baths (Müller baths) threads with a strength of 2.4 g / den. and an elongation of 18 010 when you are at 50 0j0 stretching is crazy.
