摘要： A method for providing a treated cellulose-comprising starting material (110), in particular a starting material for forming a, in particular regenerated, cellulosic molded body (102) is described. The method comprises: i) supplying a cellulose-comprising starting material (101) which comprises cellulosic fibers, and treating (20) the cellulose-comprising starting material (101), to obtain the treated cellulose-comprising starting material (110), such that the cellulose fibers of the treated cellulose-comprising starting material (110) comprises a predetermined fiber length distribution. Furthermore, a method for manufacturing a cellulosic molded body (102), a treated cellulose-comprising starting material (110), and a use of used textiles are described.

摘要： The present invention relates to a fiber of the Lyocell type which has a titer of from 0.8 dtex to 3.3 dtex and is characterized by the following relationships: Höller factor F2≥1, preferably ≥2 Höller factor F1≥−0.6 Höller factor F2≤6 and Höller factor F2 minus 4.5*Höller factor F1≥1, preferably ≥3. The fiber according to the invention displays a specific combination of properties with regard to the Höller factors, the flexibility and the abrasion resistance within a planar assembly. Hence, the fiber shows a behavior more similar to viscose and can be processed in the textile chain according to viscose standard methods.
