Abstract: To prepare cellulose mouldings, a solution of cellulose in a tertiary amine-oxide is moulded in a hot state and the moulded solution is introduced into a precipitation bath in order to precipitate the contained cellulose, wherein the hot moulded solution is cooled before introduction into the precipitation bath. Cooling occurs immediately after the moulding process and preferably consists of blowing air horizontally on to the cellulose moulding. The process according to the invention allows spinning of the cellulose solution with a high fiber density without the spun fibers sticking together after emerging from the spinneret. In spite of the high fiber density, it furthermore allows the use of a long air gap between the spinneret and the precipitation bath, by which means sufficient time is generated in the spinning process to affect the textile properties of the fibers by drawing at the die (FIG. 1).

Abstract: Apparatus for the preparation of cellulose fibers from a solution of cellulose in a tertiary amine oxide includes a spinneret having a multiplicity of spinning holes arranged essentially in a ring-shape. An inlet for cooling gas is positioned in the center of the ring-shape arrangement of the spinning holes and immediately downstream of the spinning holes. The inlet comprises a tube having a baffle plate at one end.
