Claims (4)
- Verfahren zur Herstellung von cellulosischen Formkörpern, indem Cellulose in einem Gemisch aus einem tertiären Aminoxid und einem Nichtlösungsmittel für Cellulose, z.B. Wasser, aufgelöst wird, die Lösung durch ein Formgebungswerkzeug extrudiert und die erhaltenen Filamente unter Verzug über einen Luftspalt in ein Fällbad geführt werden, dadurch gekennzeichnet, daß das Fällbad im wesentlichen aus einem nichtwäßrigen Lösungsmittel für das tertiäre Aminoxid besteht, wobei das Molekulargewicht des nichtwäßrigen Lösungsmittel größer als das des tertiären Aminoxides ist.
- Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das nichtwäßrige Lösungsmittel aus der Gruppe der Glykole, Glykolether, Polyglykole und Polyglykolether stammt.
- Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß das nichtwäßrige Lösungsmittel Polyethylenglykol ist.
- Verfahren nach zumindest einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß das tertiäre Aminoxid N-methyl-morpholin-N-oxid ist.
