摘要：

The regenerated cellulose fibers were made by the dry-wet spinning method using ionic liquid as solvent. In this work, the influence of spinning parameters including length of air layer, draw down ratio, coagulation bath concentration and coagulation bath temperature on the mechanical properties of the cellulose fibers were investigated via orthogonal design and experiments, and then the best spinning process conditions were found. The characterizations of the fibers were also analyzed. The results show that the tensile strength and the initial modulus of the regenerated cellulose fibers are mainly influenced by coagulation bath concentration and draw down ratio, and the elongation at break of the regenerate cellulose fibers is mainly influenced by the coagulation bath temperature. The fibers have higher crystallinity, better thermal stability under appropriate technological conditions, and the surface morphology is smooth. © 2019, Editorial Board of Polymer Materials Science & Engineering.
