Abstract

Det er beskrevet en fremgangsmåte ved fremstilling av cellulosefibre, idet en oppløsning av cellulose i et tertiært aminoksyd ekstruderes til filamenter gjennom spinnehull i en spinnedyse, og de ekstru- derte filamenter føres inn i et i det vesentlige vandig utfellingsbad via en luftspalte, og er sær- preget ved at de ekstruderte filamenter ved førin- gen gjennom luftspalten, bringes i kontakt med en alifatisk alkohol som foreligger utelukkende i gassform. Fremgangsmåten fører til cellulosefibre med meget liten fibrilleringstilbøyelighet.
