Abstract

See full text

A method for producing shortened anionically modified cellulose fibers having an average fiber length of 1 μm or more and 500 μm or less, the method including cleaving sugar chains of anionically modified cellulose fibers by thermal decomposition under temperature conditions of 50° C. or higher and 230° C. or lower, wherein the average fiber length of the anionically modified cellulose fibers is 700 μm or more and 10000 μm or less. By the use of shortened anionically modified cellulose fibers or the like obtained by the method for production of the present invention, a dispersion containing fine cellulose fibers having a low viscosity and excellent handling property can be prepared while at a high concentration, so that the dispersion can be suitably used in various industrial applications such as daily sundries, household electric appliance parts, packaging materials for household electric appliances, automobile parts, and materials for three-dimensional modeling.
