<p>PROBLEM TO BE SOLVED: To provide a method for finely dispersing dried oxidized cellulose fiber, which can finely disperse the dried oxidized cellulose fiber in a solvent with little environmental load, easily, and economically in the same way as preparation from an undried state, the dried oxidized cellulose fiber being capable of reducing transportation costs and having an excellent shelf life, and to provide a method for producing a fine cellulose fiber dispersion and a method for producing fine cellulose fiber.SOLUTION: Provided is a method for producing a fine cellulose fiber dispersion, comprising: a hot water treatment step where dried oxidized cellulose fiber is treated with hot water; and a dispersion step where the oxidized cellulose fiber treated with hot water is dispersed in a solvent. The dried oxidized cellulose fiber is one obtained by drying oxidized cellulose fiber obtained by oxidizing a cellulose-based raw material in a reaction liquid containing an N-oxyl compound and a co-oxidant.</p> |
