Abstract

The invention relates to a method and device for producing Lyocell fibres from a spinning solution containing water, cellulose and tertiary amine oxide. The spinning solution is extruded to form spun threads ( 10 ). The spun threads ( 10 ) are stretched and passed through a precipitation bath ( 16 ) in order to precipitate the cellulose. It has been surprisingly revealed that the tenacity of the Lyocell fibres produced in this way can be increased when the stretched fibres are subjected to post-stretching in a post-stretching means. The post-stretched Lyocell fibres have a wet modulus of at least 260 cN/tex.
