PURPOSE: To safely provide a cellulose solution for spinning solution with a simple device, by continuously supplying a cellulose suspension in a tertiary amine oxide aqueous solution onto a heated surface under a reduced pressure, spreading in layers or coats, and moving it until a homogenous solution having a specified viscosity has been formed.
CONSTITUTION: A cellulose suspension in a tertiary amine oxide (e.g.; N- methylmorpholine N-oxide or the like) aqueous solution is continuously introduced into a cylindrical vessel 2 having a stirring shaft 7 having a stirring element 8 arranged in the center through an inlet 11, the rotating speed of the stirring shaft 7 is regulated to speed the suspension on the vessel inner wall 1 heated by a heating jacket 3 in layers or coarts, the pressure in the space 15 within the vessel is reduced, the suspension is moved on the heated surface until a cellulose homogeneous solution having a viscosity of 50-15000 Pas.s has been formed, and the resulting cellulose homogeneous solution is contiguously taken out through an outlet 12, thereby, an intended solution is provided.
