Abstract

The invention concerns a method of producing cellulose fibres, the method calling for a warm solution of cellulose in a tertiary-amine oxide to be spun into filaments which are passed across an air gap and then brought into contact with a precipitating agent in order to precipitate the cellulose, the filaments being drawn off by the action of a force which stretches them in the air gap. The force is exerted by the precipitating agent by virtue of the fact that the precipitating agent is allowed to flow in the direction in which the filaments are to be drawn off and brought into contact with the precipitating agent. The method is characterized in that, when the precipitating agent is brought into contact with the filaments, it is allowed to flow at a speed which is at least as great as the speed at which the filaments are drawn off. The invention also concerns a device for carrying out the method.
