Abstract
Textile fibers of different lengths are fractionated in a liquid medium at a predetermined consistency into at least two fractions on the grounds of the fiber length, the two fractions being a first accept and a second accept. The second accept, which has longer fibers than the first accept, is led to a refining step in the liquid medium, and the refined fibers are fractionated in the liquid medium into at least two fractions on the grounds of the fiber length.
