| titleOfInvention | METHOD FOR PRODUCING SOLID REGENERATED VISCOSE FIBERS |
| abstract | A viscose spinning dope is spun through a spinneret with spinning holes, into a regenerating bath to form filaments. The filaments are stretched after leaving the regenerating bath in a secondary bath and/or in air at a stretching ratio of 70-90%, preferably 80-90%, of the maximum stretching ratio. The stretched filaments are then treated with a fatty acid ester, to obtain solid regenerated viscose fibers. A viscose spinning dope is spun through a spinneret comprising spinning holes, into a regenerating bath to form filaments. The formed filaments are stretched after leaving the regenerating bath in a secondary bath and/or in air at a stretching ratio of 70-90%, preferably 80-90%, of the maximum stretching ratio. The stretched filaments are then treated with a fatty acid ester, to obtain solid regenerated viscose fibers. The viscose spinning dope has an alkali ratio of 0.7-1, preferably 0.8-0.9, immediately before spinning. At least portion of the spinning holes have a circular orifice. The regenerating bath contains (in g/l) sulfuric acid (70-120, preferably 90-110), sodium sulfate (240-380, preferably 330-370), and zinc sulfate (20-50, preferably 25-35). The regenerating bath is maintained at 45-55[deg]C, preferably 48-50[deg]C. Independent claims are included for the following: (1) regenerated solid viscose fiber; and (2) absorbent product. |
