    • The solution contains (a) 6-35 wt.% a cellulose, its derivative or mixture thereof, (b) a tertiary amine oxide solvent containing 5-15 wt.% water, and (c) 0.5-30 wt.% an aqueous additive which is liquid phase at the lower temperature than the melting point, 150 deg.C for the cellulose or at room temperature and is mixed well without phase separation in the tertiary amine oxide/water based solvent against the total wt.% of said component (b). In the present invention, a cellulose film or fiber having an excellent physical properties can be manufactured by using the high concentrated extruding and spinning solution as a major component.
