The invention relates to a method and device for producing Lyocell(R) fibers 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 guided through a precipitation bath (16) in order to precipitate the cellulose. It has been surprisingly revealed that the strength of the Lyocell(R) fibers can be increased when the stretched fibers are subjected to a post- stretching in a post-stretching means. The post-stretched Lyocell(R) fibers have a wet modulus of at least 260 cN/tex. |
