Description
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Gewinnung von Gespinst-' fasern aus Lupinenstroh. Man hat bisher zur Gewinnung von Gespinstfasern das Lupinenstroh dadurch aufgeschlossen und die Spinnfasern freigelegt, daß man das Material mit Alkalien gekocht hat. Diese Behandlung ist aber einerseits für den in Frage kommenden Zweck nicht billig genug, anderseits ist sieThe subject of the present patent is a method for the production of web ' fibers from lupine straw. So far, lupine straw has been used for the production of web fibers opened up and the staple fibers exposed, that the material has been boiled with alkalis. This treatment is but on the one hand not cheap enough for the purpose in question, on the other hand it is
ίο geeignet, die Zellulosefaser durch Bildung von Oxyzellulose anzugreifen.ίο suitable to the cellulose fiber by forming To attack oxycellulose.
Die Erfinderin hat festgestellt, daß der gleiche Isolierungseffekt bei Lupinenstroh auf billigerem Wege und ohne Schädigung der Faser erreicht werden kann, wenn man Lupinenstroh statt mit Alkalien, mit Salzen, und zwar am ^besten der Alkalien· behandelt. Es genügen verhältnismäßig schwache Salzlösungen, und es können lösliche Salze anorganischer . 20 wie organischer Säuren verwendet werden. Insbesondere haben sich auch die billigen Stassfurter Abraumsalze oder Salzgemische als brauchbar erwiesen. Salzlösungen hat man bereits zur Gewinnung von Spinnfasern aus Pflanzen verwendet, bei der Aufschließung von Lupinenstroh sind sie aber noch nicht benutzt worden. , · - .The inventor has found that the same insulation effect on lupine straw Cheaper routes and without damaging the fiber can be achieved by using lupine straw rather than with alkalis, with salts, and preferably with alkalis. It is enough relatively weak salt solutions, and there can be soluble inorganic salts . 20 how organic acids can be used. In particular, the cheap ones too Stassfurt overburden salts or salt mixtures proved to be useful. You have salt solutions already used for the extraction of staple fibers from plants, in the digestion of But lupine straw has not yet been used. , · -.
Das Verfahren wird beispielsweise wie folgt ausgeführt:For example, the procedure is carried out as follows:
100 kg lufttrockenes Lupinenstroh · werden in etwa 5 cbm einer 1Z2- bis 5prozentigen Lösung von Kainit eingebracht und die Salzlösung wird zum Kochen erhitzt. Nach einer Kochzeit von 20 bis 40 Minuten ist die Bloßlegung der Faser erfolgt, das Lupinenstroh wird aus der Lauge herausgebracht, ausgewaschen und getrocknet. Aus der so erhaltenen rohen Fasermasse wird dann die Gespinstfaser in bekannter Weise mechanisch weiter isoliert.100 kg of air-dry lupine straw are placed in about 5 cbm of a 1 Z 2 to 5 percent solution of kainite and the salt solution is heated to the boil. After a boiling time of 20 to 40 minutes, the fibers are exposed, the lupine straw is removed from the liquor, washed out and dried. The roving fiber is then further mechanically isolated in a known manner from the raw fiber mass obtained in this way.
