The present invention relates to a powder of modified cellulose fibers having an average fiber length of 1 μm or more and 500 μm or less, wherein the modified cellulose fibers are made from anionically modified cellulose fibers introduced at an anionic group with a modifying group; a dispersion containing a powder of modified cellulose fibers as defined above and a medium, wherein the powder of modified cellulose fibers is dispersed in the medium; a resin composition containing a powder of modified cellulose fibers as defined in above and a resin, wherein the powder of modified cellulose fibers and the resin are blended; and a resin molded article obtained by molding a resin composition as defined above. According to the present invention, a powder of cellulose fibers having excellent dispersibility in a solvent, which can be obtained by an inexpensive process, and a method for producing the same can be provided.
A powder of modified cellulose fibers having an average fiber length of 1 μm or more and 500 μm or less, wherein the modified cellulose fibers are made from anionically modified cellulose fibers introduced at an anionic group with a modifying group, and wherein the powder of modified cellulose fibers has an average fiber diameter of 0.1 μm or more and 200 μm or less.
