  • Publication number: 20210087713
    Abstract: The present invention relates to a method for producing fine hydrophobically modified cellulose fibers wherein anionic group-containing anionically modified cellulose fibers are bound to a modifying group, the method including subjecting hydrophobically modified cellulose fibers having an average fiber length of 1 ?m or more and 1,000 ?m or less to a finely pulverizing treatment in an organic solvent. The fine hydrophobically modified cellulose fibers obtained by the method for production of the present invention can be suitably used in various resin manufactured articles for daily sundries, household electric appliance parts, wrapping materials for household electric appliance parts, and various industrial applications such as automobile parts.

  • Publication number: 20210054541
    Abstract: A method for producing shortened anionically modified cellulose fibers having an average fiber length of 1 ?m or more and 500 ?m 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 ?m or more and 10000 ?m 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.
