| titleOfInvention | Method for producing cellulose nanofiber dispersion |
| abstract | [PROBLEMS] To reduce the average fiber width and the average fiber length of CNF in a cellulose nanofiber (CNF) dispersion with a small number of passes, and to provide a highly transparent CNF that can be used for a transparent sheet for a display or the like. Provision of a method for producing a dispersion. SOLUTION: A method for producing a CNF dispersion obtained by colliding high-pressure water of about 50 to 400 MPa with a polysaccharide made into an aqueous mixture and defibrating, wherein before the defibrating step, α -A carboxy group introduction step for introducing a carboxyl group into a pulp having a cellulose content of 60 to 99% with a compound having two or more carboxyl groups; and a washing step for washing the pulp after the carboxyl group introduction step. A method for producing a highly transparent CNF dispersion, comprising: an alkali treatment step of treating the pulp after the washing step with an alkali solution; and a washing step of washing the pulp after the alkali treatment step.
