    摘要: The invention relates to a fiber bundle containing a plurality of regenerated multi-limbed cellulose fibers (1', 2'), the cross-section of which has three or more limbs. The fiber bundle according to the invention is characterized in that at least 10%, preferably at least 20%, particularly preferably at least 50% of the multi-limbed cellulose fibers are asymmetrical fibers, in which at least one of the limbs differs from the other limbs with respect to length and in which the length of one or more limbs is greater than the length of the shortest limb(s) by a factor of 2 to 10.
