- 3. A method of manufacturing a cellulose based fiber of high water retentivity according to claim 1, wherein the polyacrylate salt is mixed into viscose rayon, to a final content of 10% by weight or more to 200% by weight or less to the total weight of the cellulose material in the viscose, and the resulting mixture is used as a stock solution.
- 4. A method of manufacturing a cellulose based fiber of high water retentivity according to claim 1, comprising treatment with an alkaline solution after refining.
