Method for producing short fiber anionic cellulose modified fiber

摘要

An anionic modified cellulose fiber containing a step of dissolving a sugar chain by thermal decomposition under a temperature condition of 50 to μ Over 500 μ The method of producing a short fibrous anionic modified cellulose fiber that is less than m is an average fiber length of anionic modified cellulose fiber μ More than μ Manufacturing method which is m or less.By using a short fiber anionic modified cellulose fiber obtained by the manufacturing method of the present invention, it is possible to prepare a dispersion containing a highly concentrated cellulose fiber having a high concentration and low viscosity and high handling ability, and packaging materials for daily use goods, household electric appliances, and household appliances It can be suitably used for various industrial applications such as automobile parts and three-dimensional molding materials.
