Abstract
A method and a 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 fibers in the fiber tow are fixated and stretched to essentially their final cellulose specific diameter before being cut to staple fibers in an undried state.
