Description
AUSGEßEBEft AM 22. SEPTEMBER 1919EXTENDED ON SEPTEMBER 22, 1919
in CHARLOTTENBURG.in CHARLOTTENBURG.
Bisher wurden die die eigentlichen Fasern umhüllenden Bestandteile durch Kochen in schwacher Natronlauge gelöst oder auswaschbar gemacht und dann durch kräftiges Spülen mit kaltem oder heißem Wasser freigelegt. Naturgemäß verwirren sich hierbei die Fasern, gleichgültig, ob das Auswaschen in Waschmaschinen oder von Hand erfolgt, in erheblichem Maße, wodurch bei der mechanischen Weiterbearbeitung (Hecheln oder Krempeln) entsprechende Verluste entstehen.Up to now, the constituents surrounding the actual fibers were cooked in weak caustic soda dissolved or made washable and then rinsed vigorously exposed with cold or hot water. Naturally, the fibers become tangled here, Regardless of whether the washing is done in washing machines or by hand, to a considerable extent, which in the mechanical Further processing (panting or carding) results in corresponding losses.
Durch das vorliegende Verfahren soll dieser Übelstand dadurch beseitigt werden, daß das Waschen zum Ausspülen des Gelösten fortfällt und diese inkrustierenden Stoffe auf mechanischem Wege entfernt werden.The present method is intended to remedy this deficiency in that there is no washing to rinse out the solute and these encrusting substances are removed removed mechanically.
Die Aufschließung der Pflanzen nach dem neuen Verfahren geschieht in folgender Weise:The digestion of the plants according to the new process takes place in the following Way:
Die Pflanzen werden, gegebenenfalls nachdem die starken Stengelteile vorher gespalten worden sind, in schwacher alkalischer Lösung (Natron- oder Kalilauge, Ätzkalklösung o. dgK) durch Kochen oder aber in einem Säurebad gelöst, auf der Zentrifuge oder durch Abtropfenlassen entwässert und dann scharf getrocknet. Hierauf läßt man die so vorbereiteten Pflanzen, welche ihre Struktur beibehalten haben, durch ein geeignetes Brechwalzwerk gehen und behandelt sie dann 3°' auf Maschinen, wie solche bei der Bearbeitung, des Flachses u. dgl. benutzt werden, The plants are, if necessary after the strong stem parts have been split up beforehand, in a weak alkaline solution (sodium or potassium hydroxide, caustic lime solution or similar) by boiling or in an acid bath, dehydrated on the centrifuge or by draining and then dried sharply. The plants prepared in this way, which have retained their structure, are then passed through a suitable crushing mill and then treated 3 ° on machines, such as those used in processing, flax and the like.
