Three-dimensional cellulosic molded body, which has an optically detectable core-shell structure, where the envelope has a higher density and lower crystallinity than the core and the core has a sponge-like structure, characterized in that the envelope has a density relative from 65% to 85% and the core has a relative density of 20% to 60% -referred to compact cellulose-, the thickness of the envelope ranges between 50 μ 200 μa thickness ratio of the envelope and the total diameter of the envelope molded body ranges from 1: 5 to 1:50 and the ratio of the shafts of the molded body does not exceed 3: 1. |
