Abstract (en)
[origin: WO9501470A1] In order to produce cellulose fibres, a solution of cellulose in a tertiary amino oxide is hot-shaped into filaments, the filaments are cooled and brought into a precipitation bath in order to precipitate the dissolved cellulose. Before being brought into the precipitation bath, the shaped solution is exposed for cooling to a substantially laminar gas current.
