Abstract

The present invention relates to a dope for spinning lyocell, comprising cotton linter pulp and an aqueous solution of N-methylmorpholine-N-oxide (NMMO), to a method for preparing a lyocell filament fiber using the dope, to a lyocell filament fiber prepared by means of the method, to a method for preparing a lyocell staple fiber using the dope, and to a lyocell staple fiber prepared by means of the method. The fiber of the present invention has a low degree of orientation and a low degree of fibrillation and exhibits high elongation even without additional processes, and therefore can be used as fibers for high-quality clothing.
