Zusatz zum Patente 228872 vom 20. Februar 1908.*)Addendum to patent 228872 of February 20, 1908. *)
Patentiert im Deutschen Reiche vom 26. Juni 1908 ab. Längste Dauer: 19. Februar 1923.Patented in the German Empire on June 26, 1908. Longest duration: February 19, 1923.
Nach dem Hauptpatent werden Kohlehydrate, wie Mono- und Polysaccharide, der mittels Kupferoxydammoniak gelösten Zellulose einverleibt. Auf diese Weise wird eine Spinnmasse mit besonders wertvollen Eigenschaften erhalten.According to the main patent, carbohydrates such as mono- and polysaccharides, the incorporated cellulose dissolved by means of copper oxide ammonia. This way it becomes a spinning mass with particularly valuable properties.
Es wurde nun gefunden, daß nicht allein die mehrwertigen Alkohole, die zu den Kohlehydraten gerechnet werden, die Eigenschaft besitzen, Zelluloselösungen in vorteilhafter Weise zu verändern, sondern auch noch eine Reihe anderer Alkohole, wie z. B. Mannit, Dulcit. Vermischt man derartige Stoffe mit der Zelluloselösung, entsprechend der im Hauptpatent gegebenen Vorschrift, so erlangen die Lösungen ebensolche wertvollen Eigenschaften wie nach dem Verfahren des Hauptpatentes. It has now been found that it is not only the polyhydric alcohols that make up the carbohydrates are expected to have the property of changing cellulose solutions in an advantageous manner, but also another Number of other alcohols such as B. mannitol, dulcitol. If you mix such substances with the cellulose solution, according to the regulation given in the main patent the solutions have just as valuable properties as after the process of the main patent.
