摘要： The invention relates to a regenerated cellulose fiber with a multi-limbed cross-section. The fiber according to the invention is characterized in that the cross-section consists of at least two multi-limbed basic shapes (1', 2', 3', 4'), each basic shape being connected to the limb end of another basic shape at at least one of the basic shape limb ends. The length of the connecting limb (12) resulting from the connection of the two limb ends is longer than the length of the shortest of the other limbs by a factor of at least 1.5, preferably 1.5 to 2.0.

摘要： The present invention relates to a filter auxiliary agent for a pre-coat filter, said agent comprising regenerated cellulose fibres. The invention also relates to a method for filtering or stabilizing an unfiltered product, comprising the steps: provision of a pre-coat filter; pre-coating of a filter means of the pre-coat filter with regenerated cellulose fibres acting as a filter auxiliary agent, in order to form a filter layer and passing of the unfiltered product through the filter layer that has been formed. Also disclosed is a filter layer comprising regenerated cellulose fibres for a plate press, plate-and-frame filter or plate filter for filtering a beverage.

摘要： The invention relates to a method for strengthening a nonwoven fabric by means of a water jet treatment. The method according to the invention is characterized in that the nonwoven fabric contains flat fibers in the form of collapsed hollow viscose fibers with a ratio of width B to thickness D of B:D ≥ 10:1.

摘要： The invention relates to regenerated cellulose fibre characterized by the combination of the following properties:- the fibre in the dry state has a collapsed hollow cross-sectional structure; - the fibre in the wet state has a cross-sectional structure with cavities; - the fibre in the longitudinal direction has segmentation as a result of dividing walls; - the fibre incorporates an absorbent polymer, more particularly carboxymethylcellulose. The fibre is obtainable by a process in which a viscose spinning composition is admixed both with a carbonate and with an absorbent polymer, more particularly carboxymethylcellulose.
