  • Patent number: 10435481
    Abstract: The present invention relates to a regenerated cellulose fiber having a multi-limbed cross-section. The fiber according to the invention is characterized in that the cross-section is formed of at least two multi-limbed basic shapes (1?, 2?, 3?, 4?), which basic shapes are connected, in each case at least at one of their limb ends, to the limb end of another basic shape and the length of the connecting limb (12) resulting from the connection of the two limb ends is longer than the length of the shortest one of the other limbs by a factor of at least 1.5, preferably of from 1.5 to 2.0.
    Type: Grant

  • Publication number: 20140148590
    Abstract: The present invention relates to a fiber bundle containing a plurality of regenerated multi-limbed cellulose fibers (1?,2?) the cross-sections of which exhibit 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, wherein at least one of the limbs deviates in its length from the other limbs and wherein the length of one or several limbs is greater than the length of the shortest limb(s) by a factor of 2 to 10.

  • Publication number: 20140147616
    Abstract: The invention relates to a regenerated cellulose fiber (1?) the cross-section of which comprises an oblong, essentially flat section (3). The fiber according to the invention is characterized in that at least one limb (4, 5, 6, 7) branches off from the oblong section, wherein the length of said limb is at most 40% of the length of the oblong section (3).
