| 摘要 |
The present invention addresses the issue of obtaining high-strength, high-elasticity, long regenerated cellulose fibers. In long regenerated cellulose fibers obtained by dissolving a cellulose raw material in an ion liquid and spinning same, the dissolving conditions are adjusted such that the type I cellulose crystal content is 0.1%-35%, and high-strength, high-elasticity, long regenerated cellulose fibers are obtained by spinning. |
