Abstract (en)
[origin: WO0200975A1] The invention relates to a method for producing cellulose fibres. According to said method, a solution of cellulose in a tertiary amino oxide is extruded through the spinning holes of a spinneret and the extruded filaments are fed into a precipitation bath whilst being drawn via an air gap. The filaments are exposed to a gaseous stream in the air gap. The invention is characterised in that the temperature (T) of the gas prior to the contact with the filaments is represented by the formula: 60 DEG C < T < 90 DEG C.
