摘要： Disclosed is a process for preparing a homogeneous cellulose solution which is capable of, forming a mixture where a cellulose pulp powder is mixed and swollen with a liquid NMMO hydrate solvent supercooled under a melting point and subjecting the mixture to a dissolution treatment, thereby producing a homogeneous cellulose solution having a substantially low decomposition characteristic. The process produces a cellulose pulp mixing powder that is first swollen in a liquid NMMO solvent supercooled under a melting point by minimizing the dissolution of cellulose by the liquid NMMO solvent and maximizing the swelling thereof by the liquid NMMO solvent, thereby resulting in a maximum homogeneity of the solution and maintains the minimized decomposition states of the cellulose and the NMMO solvent, thereby resulting in the improvement of productivity and the simplicity of the process.
