Description

..' V o Verfahren zur Herstellung langer hechel- und verspinnbarer Fasern aus Getreidestroh Das Hauptpatent betrifft die Herstellung .einer verspinabaxen Faser ,aus Getreidestroh, wobei ein Glied des Herstellungsverfahrens die schonende Alkalibehandlung des Strohes ist. Diese Behandlung erfolgt dort durch etwa einstündiges Kochen in einer Lösung, die etwa o,5 bis i % Alkalihydroxyd und i bis a o;o Netzmittel enthält... 'V o A process for preparing long hechel- and spinnable fibers from cereal straw, the main patent relates to the preparation .One verspinabaxen fiber from cereal straw, wherein a member of the manufacturing process is the gentle alkali treatment of straw. This treatment takes place there by boiling for about one hour in a solution which contains about 0.5 to i% alkali metal hydroxide and i to ao; o wetting agent.

In weiterer Ausarbeitung dieses Verfahrens wurde gefunden, daß das Kochen vorteilhafterweise durch eine etwas längere Behandlung des Strohes mit den heißen alkalischen Netzmittellösungenersetzt werden kann. Diese Behandlung besteht in einem Einweichen des Strohes in der 6o bis 8o° warmen Lösung auf die Dauer von q. bis 6 Stunden. Man kann auch bei niedrigeren Temperaturen arbeiten, wobei die Einwirkungszeit entsprechend zu verlängern ist.In further elaboration of this procedure it was found that the Cooking advantageously by treating the straw with the straw for a little longer hot alkaline wetting agent solutions can be replaced. This treatment persists by soaking the straw in the 6o to 8o ° warm solution for a period of q. up to 6 hours. You can also work at lower temperatures, with the The exposure time is to be extended accordingly.

Der Angriff. der Aufschlußlösung auf die die Faser liefernde Strohsubstanz wird hierdurch erheblich abgeschwächt,- und die Inkrustierungen werden doch in ausreichendem Maße entfernt. Infolgedessen bleibt die faserliefernde Substanz fester und stärker und ist erheblich weniger zum Quellen geneigt. Das ist sowohl für die Weiterverarbeitung als auch für die Verwendung von großem Vorteil. Ausführungsbeispiel 15 kg gebündeltes und gewalztes Roggenlangstroh werden in ein heißes' Bad gelegt, das o,8 % Ätznatron und i oo hochsulfoniertes Fett enthält, 5 Stunden darin gelassen, wobei: die Temperatur zwischen 70 bis 8o' gehalteä wird, dann mehrere Male gespült, schwach abgesäuert, fast lufttrocken gemacht, in diesem Zustande gewalzt, mit 25 % einer ölemulsion gefettet und nach mehrstündigem Lagern auf Hecheln zerfasert.The attack. the decomposition solution on the straw substance supplying the fiber is hereby considerably weakened, - and the incrustations are nevertheless removed to a sufficient extent. As a result, the fiber-producing substance remains firmer and stronger and is considerably less prone to swelling. This is of great advantage both for further processing and for use. Embodiment 15 kg of bundled and rolled long rye straw are placed in a hot bath containing 0.8% caustic soda and 100% highly sulphonated fat, left in it for 5 hours, during which: the temperature is kept between 70 to 8o ', then rinsed several times, weakly acidified, made almost air-dry, rolled in this condition, greased with 25 % of an oil emulsion and, after storage for several hours, frayed on hackles.
