Verfahren zur Herstellung von Fäden und Films aus Viskose.
Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Fäden und Films aus Viskose. Bei den bisher bekannten Verfahren wurden zur Fällung Säuren, Kochsalz, Alkohol, Chlorammonium und andere Ammoniumsalze verwendet.
Gemäss vorliegender Erfindung wird durch die Einwirkung von Lösungen der Salze organischer Basen, wie z. B. Naphthylamin, Pyridin u. a. das Ausfällen der Viskose aus der Lösung bewirkt.
Man bringt die Viskose in die gewünschte Form (Fäden oder Films), was entweder vermittelst Durchführung der Lösung durch entsprechende Öffnungen oder Bedeckungen von Oberflächen erreicht wird und leitet die gebildeten Fäden oder Films hierauf in die Lösung von Salzen verschiedener organischer Basen. Hiebei wird die Zellulose in un-

Process for making threads and films from viscose.
The present invention relates to a method of making threads and films from viscose. In the previously known processes, acids, common salt, alcohol, chlorammonium and other ammonium salts were used for the precipitation.
According to the present invention, the action of solutions of the salts of organic bases, such as. B. naphthylamine, pyridine and. a. causes the viscose to precipitate out of solution.
The viscose is brought into the desired shape (threads or film), which is achieved either by passing the solution through appropriate openings or coverings of surfaces, and the threads or films formed are then passed into the solution of salts of various organic bases. In this case, the cellulose is

To obtain the salts from the separated bases, one either saturates the losing ones with the vapors of the corresponding acids, or one adds an acid with a certain titer to the solution.
One can add indicators such as lakmus to the salts themselves.

1. The removal of the organic bases from the cellulose that is being formed can be done more easily than before. sieve the difficult or not at all volatile

2. During the production of threads and film, the latter can be colored immediately (e.g. aniline black or also direct coloring), which results in great savings and simplification of the production process.
The procedure is carried out in the following way:
