Verfahren zur Herstellung einer als Spinn lösung dienenden KupferoxydammoniakZelluloselösung.
EMI1.1
Beispiel :
EMI1.2
schnittene Baumwollfaser zu, trennt dann in Filterpressen die Flüssigkeit, welche das entstandee Glaubersalz enthält, von dem Faserteig. Der letztere enthält jetzt das Kupferhydroxyd nebst den organischen Substanzen. Nun gibt man 1000 cm3 Ammoniak von 910 spezifisches Gewicht hinzu. Gleichzeitig mit dem Ammoniak oder auch nachträglich kann man noch weitere Mengen organischer Substanzen hinzufügen.
In kurzer zeit entstehen auf diese Weise völlig homogene Lösungen, welche sich vorzüglich zur Herstellung selbst der feinsten Fädchen eignen.

Process for the preparation of a copper oxide ammonia cellulose solution serving as a spinning solution.
EMI1.1
Example:
EMI1.2
cut cotton fiber, then separates the liquid, which contains the Glauber's salt, from the fiber dough in filter presses. The latter now contains the copper hydroxide together with the organic substances. Now 1000 cm3 of ammonia with a specific weight of 910 are added. At the same time as the ammonia or afterwards, you can add further quantities of organic substances.
In this way, completely homogeneous solutions are created in a short time, which are ideal for producing even the finest threads.
