Title:
Ｉ型結晶含有再生セルロース長繊維
Document Type and Number:
Japanese Patent JP5930129
Kind Code:
B2
Abstract:
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.
