摘要:
The invention relates to a regenerated cellulose fiber, which has a hydrophobic substance incorporated in the cellulose matrix. The hydrophobic substance is selected from the group comprising alkyl ketene dimers, alkenyl ketene dimers, alkyl succinic anhydrides, alkenyl succinic anhydrides, alkyl glutaric acid anhydrides, alkenyl glutaric acid anhydrides, alkyl isocyanates, alkenyl isocyanates, fatty acid anhydrides, and mixtures thereof.
摘要:
The invention relates to a regenerated cellulose fiber in the form of a solid viscose flat fiber having the following properties: the fiber is made of more than 98% cellulose; the ratio of the width B to the thickness D of the fiber is 10:1 or greater; the fiber surface is substantially smooth; and the fiber is substantially transparent. The fiber according to the invention is suitable in particular for producing paper.
摘要:
The invention relates to a regenerated cellulose fiber (1"), the cross-section of which has a substantially flat elongated section (3). The fiber according to the invention is characterized in that at least one limb (4, 5, 6, 7) branches off from the elongated section, the length of said limb being maximally 40% of the length of the elongated section (3).
摘要:
The invention relates to a fibre composite comprising or consisting of natural and/or synthetic fibres. Said fibre composite is characterised in that at least some of the fibres of the composite have a flat cross-section and it can be dissolved or decomposed in water or other liquids.
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.
