The present invention relates to the use of a viscose fibre for the production of a transparent cosmetic mask. The use according to the invention is characterized in that the viscose fibre is a flat fibre, the cross section of the viscose fibre has a width-to-thickness ratio of 6:1 to 30:1, and the titre of the viscose fibre ranges from 1.0 dtex to 4 dtex.

Use of a viscose fiber

The present invention relates to a modified cellulosic fiber that comprises anionic moieties in an amount of more than 0.25 mol/kg of dry fiber and has applied thereon a polymeric modifying agent in an amount of from 0.5 wt. % to 5.0 wt. %, based on dry fiber, the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5 meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fiber is in the range of from 1:1 to 25:1. The fiber according to the present invention is characterized in that the anionic moieties are incorporated in the fiber and are from carboxymethylcellulose, and that the polymeric modifying agent comprising cationic moieties is selected from the group consisting of polydiallyldimethylammonium chloride (poly-DADMAC), poly(acrylamide-co-diallyldimethylammonium chloride) (PAM-DADMAC) and mixtures thereof. The invention furthermore relates to a nonwoven product or fabric comprising the modified cellulosic fiber.

Man-made cellulosic fiber and nonwoven product or fabric comprising the cellulosic fiber

The invention relates to a regenerated cellulose fiber in the form of a solid viscose flat fiber having the following properties:

Regenerated cellulose fiber

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 ('), 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 () 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.

The present invention relates to a regenerated cellulose fiber, which is characterized by the combination of the following features: The fiber may be obtained by a process, wherein there is admixed a carbonate as well as an absorbent polymer, in particular carboxymethylcellulose, to a viscose dope.
