The manufacturing method of fine cellulose fiber containing dry solid matter

SUBJECT of the Invention The manufacturing method of the fine cellulose fiber containing dry solid matter which simply manufactures the fine cellulose fiber containing dry solid matter which is excellent in re-dispersibility with respect to solvent， such as water， is provided. PROBLEM to be solved The manufacturing method of the fine cellulose fiber containing dry solid matter of this invention includes the process dried in a comparatively low temperature state by low voltage|pressure conditions. And the sulfur introduction amount based on a sulfo group in the fine cellulose fiber containing dry solid matter manufactured by 1 aspect of this invention contains a fine cellulose fiber 0.5 mmol/g or more， Therefore It is excellent in re-dispersibility from a viewpoint of transparency， a viscosity characteristic， and the precipitation characteristic.
