摘要:
The present invention describes a method of dissolving cellulose, said method comprising: - dissolving cellulose in an alkali solution; -filtering the dissolved cellulose, thereby forming a filtered dissolved cellulose solution and a filter reject; - mixing said filter reject having a first viscosity value with a dissolution liquid having a second viscosity value, wherein the second viscosity value is lower than the first viscosity value, to provide a diluted reject stream having a third viscosity value being lower than the first viscosity value of the filter reject; and - separating inhomogeneities from the diluted reject stream.

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.
