Abstract

The invention refers to the manufacture of staple fibers of filaments (2), which are manufactured according to the lyocell method from a spinning solution containing water, cellulose and tertiary amine oxide. According to the invention it is provided that the tertiary amine oxide is not washed out of the filaments (2) before cutting by using cutting means (9). By this measure the loop strength can be increased. Particularly, loop strengths in lyocell fibers of at least 15 cN/tex, partially even at least 20 cN/tex can be achieved in the method and the device according to the invention.
