1. Förfarande för framställning av cellulosa-formkroppar, i synnerhet cellulosafibrer, varvid 5. ett cellulosahaltigt material tillförs en vat- tenlösning av en tertiär aminoxid för att suspendera det cellulosahaltiga materialet, - vatten avlägsnas ur suspensionen under intensiv omblandning och vid förhöjd temperatur och reducerat tryck 10 tills en lösning av cellulosan bildas, och - lösningen formas med användning av ett formverk-tyg, i synnerhet en spinningsdysa, och införs i ett fäll-bad för att fälla ut den lösta cellulosan, kanne -tecknat av att som cellulosahaltigt material i hu- 15 vudsak används sönderdelat returpapper, sönderdelade cellulosahaltiga fibermaterial och/eller sönderdelade meka-niskt och/eller kemiskt uppslutna ettariga växter.
2. Förfarande enligt krav 1, känneteck- n a t av att den för f ramställning av suspensionen 20 använda vattenhaltiga lösningen innehäller tertiär aminoxid i en hait mellan 60 och 72 vikts-%.
: 3. Förfarande enligt krav 1, känneteck- ; n a t av att som cellulosamaterial dessutom används hög- ; värdig kemisk cellulosa. 2 5
4. Förfarande enligt nägot av kraven 1 tili 3, , ·, kännetecknat av att som tertiär aminoxid an- vänds N-metyl-morfolin-N-oxid. * ·
5. Förfarande enligt nägot av kraven 1 tili 4, kännetecknat av att lösningen bildas pä sä *··: 30 sätt att: - suspensionen kontinuerligt tillförs ett evakuer- : bart, uppvärmningsbart kärl, .1··. - den tillförda suspension bredes ut mekaniskt skikt- resp. filmformigt för bildning av tvä ytor, 35. den utbredda suspensionen bringas för *...· värmetillförsel i kontakt med en yta som är uppvärmd, 114221 - den utbredda suspensionen transporteras under intensiv omblandning over den uppvärmda ytan, under transporten over den uppvärmda ytan utsätts den fran den varma ytan vända andra ytan för ett 5 reducerat tryck för att föränga vatten tills det cellulosahaltiga materialet gätt i lösning, och - lösningen kontinuerligt dras av frän kärlet. » 1 · » I · • »
