MANUFACTURING METHOD OF CELLULOSE FIBER CONTROLLED DEGREE OF CRYSTLLITY ACCORDING TO SOLIDIFICATION RATE AND CELLULOSE FIBER PRODUCED BY USING THE SAME

摘要

The present invention relates to a method for manufacturing cellulose fiber capable of controlling the degree of crystallinity according to a solidification rate and, more particularly, to a method for manufacturing cellulose fiber having a low microstructure owing to a low solidification rate when a cellulose solution is manufactured using an an ionic liquid solvent as a mixed solution for dissolving cellulose. Process yield and efficiency are improved when cellulose fiber is manufactured using a high-concentration spinning solution as the cellulose solution manufactured according to the present invention uses an ionic liquid with high solubility. Also, a method for manufacturing cellulose fiber having a low microstructure owing to a low solidification rate is ensured to be able to adjust the microstructure of fiber by configuring correlation between the solidification rate and the degree of crystallinity.
