Abstract (en)
[origin: EP2589689A2] This disclose relates to dope for spinning lyocell including cotton linter pulp and an aqueous solution of N-methylmorpholine-N-oxide (NMMO), a method for manufacturing lyocell filament fiber using the dope, lyocell filament fiber manufactured by the method, a method for manufacturing lyocell staple fiber using the dope, and lyocell staple fiber obtained by the manufacturing method. According to the present invention, fiber that exhibits a low orientation degree and fibrillation degree, and a high elongation, and thus may be applied for fiber for high grade clothing, may be provided without conducting additional processes.
