Abstract (en)

[origin: US5601771A] The invention is concerned with a process for the production of cellulose fibres, wherein a solution of cellulose in an aqueous tertiary amine-oxide is extruded into filaments through spinning holes of a spinneret and the extruded filaments are conducted across an air gap into a substantially aqueous precipitation bath, characterized in that the extruded filaments, while being conducted across the air gap, are contacted with an aliphatic alcohol which is present exclusively in gaseous state. The process according to the invention produces cellulose fibres having a very reduced tendency to fibrillation.
