Abstract: The invention relates to a method for the production of lyocell staple fibers, comprising the steps in the following order: a) extruding filaments from a solution of cellulose in an organic solvent; b) precipitating the cellulose for the formation of continuous cellulose filaments; c) washing the cellulose filaments; d) contacting the cellulose filaments with a crosslinking agent; e) reacting the cellulose filaments with the crosslinking agent in a reaction chamber; f) washing the treated cellulose filaments; g) cutting the washed cellulose filaments into staple fibers; h) forming a nonwoven fleece from the staple fibers and pressing the nonwoven fleece; and i) finishing the nonwoven fleece and pressing the nonwoven fleece.

Abstract: The present invention relates to a three-dimensional cellulosic molded body that has an optically detectable core/shell structure, the shell having a higher density and a lower crystallinity than the core, and the core having a sponge-like structure. The invention further relates to a method for producing this molded body as well as to its use, especially in the cosmetics and pharmaceutical industries.
