Method for producing regenerated cellulosic fibers |
| abstract |
Method and production facility for producing regenerated cellulosic fibers. A spinning solution is extruded into a coagulation bath which contains a salt and preferably an alkali. The spinning solution comprises cellulose dissolved in an aqueous solvent comprising NaOH and ZnO and the coagulation bath has a pH-value of at least seven. The processing facility comprises a cutter to cut the fiber tow in an undried state into cut fibers, a fleece-forming device for suspending the cut fibers and collecting them in form of a non-woven fiber layer, and at least on pressing device for pressing the non-woven fiber layer, thereby imposing a natural crimp on the fibers. |
