Abstract (en)

[origin: WO9607779A1] In a process for manufacturing cellulose moulded bodies, cellulose is dissolved in a mixture of a tertiary amine oxide and a non-solvent for cellulose, for example water, the solution is extruded through a shaping tool and the thus obtained filaments are drawn through an air gap into a regenerating bath. The process is characterised in that the regenerating bath essentially consists of a non-aqueous solvent for tertiary amine oxide having a molecular weight higher than that of the tertiary amine oxide. Solvent-spun fibres with hardly any fibrillation tendency may thus be obtained. Polyethylene glycols are preferably used.
