Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Nach vorliegendem Verfahren werden Lösungen von Alginsäure zur Herstellung von Kunstfäden benutzt.According to the present process, solutions of alginic acid are used for the production of artificial threads used.

Es wurde die überraschende Tatsache gefunden, daß derartige Lösungen, die nach bekannter Arbeitsweise aus feinen Öffnungen in geeignete koagulierende Bäder gespritzt werden, zusammenhängende und verspinnbare Fäden ergeben, die als künstliche Seide, künstliebes Roßhaar u. dgl. Verwendung finden können. Man bedient sich zweckmäßigerweise wäßriger Auflösungen der alginsauren Alkalien mit einem Gehalt von etwa io Prozent festen " Bestandteilen.It has been found the surprising fact that such solutions, according to known Working method from fine openings are injected into suitable coagulating baths, coherent and spinnable Threads result that can be used as artificial silk, artificial horsehair and the like. It is expedient to use aqueous solutions of the alginic acid alkalis with a content of about 10 percent "solid" components.

' Als brauchbare Fällungsmittel für vorliegenden Zweck haben sich u. a. Lösungen von Metallsalzen erwiesen und unter diesen wieder als die besten die löslichen Kalk-, Strontium- und Bariumsalze.As usable precipitants for the present purpose, inter alia. Solutions from Metal salts and among these again the best soluble lime, strontium and barium salts.

Besonders gute Ergebnisse erzielt man dadurch, daß man die koagulierenden Bäder bei erhöhter Temperatur (etwa 70 bis 8o° C.) einwirken und die Trocknung unter Spannung erfolgen läßt. Während durch die erhöhte Temperatur die Verspinnbarkeit begünstigt wird, bewirkt die Trocknung unter Spannung eine Herabsetzung des Quellungsvermögens des Endproduktes. Gegenüber den bisher geübten Verfahren besitzt das vorliegende u. a. den Vorzug der Einfachheit und Billigkeit.Particularly good results are achieved by using the coagulating baths act at elevated temperature (about 70 to 80 ° C.) and the drying under tension can be done. While the spinnability is favored by the increased temperature, Drying under tension reduces the swelling capacity of the end product. Compared to the previously practiced method, the present has inter alia. the merit of simplicity and cheapness.

Man hat zwar nach der britischen Patentschrift 6700/1898 bereits die gelatinierende Substanz aus Seepflanzen zur Herstellung von Kunstfäden benutzt. Dabei handelt es sich indessen um die Agar-Agar genannte und nur in der Wärme flüssige Gelose, während beim vorliegenden Verfahren die kalt verwendbaren, nicht gelatinierenden, chemisch und physikaAccording to British patent specification 6700/1898, the gelatinizing one already has Substance from sea plants used to make artificial threads. It is about meanwhile gelose called agar-agar and only liquid when heated, while with The present processes are cold, non-gelatinizing, chemical and physical

lisch verschiedenartigen Alginsäurelösungi
Verwendung kommen, deren Verspinnbarkeit in Verbindung mit geeigneten Koagulationsmitteln auch ganz unvergleichlich besser ist als diejenige von Geloselösungen. Auch aus der bereits bekannten Tatsache, daß man Alginsäurelösungen zu biegsamen Häutchen eintrocknen und diese durch koagulierende Stoffe, z. B. Metallsalze, unlöslich machen kann (vgl. Meyer, Vareleksikon, 2. Udgave 1907, Kopenhagen und Kristiania, S. 763; Chemiker-Zeitung 1910, S. 1149 und 1150), war nicht zu erkennen, daß die Alginsäurelösungen in Berührung mit koagulierenden Stoffen bzw. beim Durchgange durch fällende Bäder ganz plötz-, · lieh diese überraschende Bildung von abspulbaren und verspinnbaren Fäden zeigen würden.different types of alginic acid solution
Use, whose spinnability in connection with suitable coagulants is also incomparably better than that of solution solutions. Also from the already known fact that you can dry alginic acid solutions to flexible skins and these by coagulating substances such. B. metal salts, can make insoluble (see. Meyer, Vareleksikon, 2. Udgave 1907, Copenhagen and Kristiania, p. 763; Chemiker-Zeitung 1910, p. 1149 and 1150), it could not be seen that the alginic acid solutions in contact with coagulating substances or quite suddenly when passing through precipitating baths, this surprising formation of unwindable and spinnable threads would show.
