PCT No. PCT/AT95/00174 Sec. 371 Date Jun. 21, 1996 Sec. 102(e) Date Jun. 21, 1996 PCT Filed Sep. 4, 1995 PCT Pub. No. WO96/07779 PCT Pub. Date Mar. 14, 1996The disclosure describes a process for the manufacture of cellulosic moulded bodies in which cellulose is dissolved in a mixture of a tertiary amine oxide and a non-solvent for cellulose, e.g. water. The solution is extruded via a moulding tool and the filaments received are led via an air gap to a precipitation bath whilst being drawn. The process is characterised in that the precipitation bath substantially comprises a non-aqueous solvent for the tertiary amine oxide, whereby the molecular weight of the non-aqueous solvent is larger than that of the tertiary amine oxide. In this manner, solvent-spun fibers with a lower fibrillation tendency can be obtained. Polyethylene glycols are preferably used. |
