Title:
MODIFIED CELLULOSE FIBER POWDER
Document Type and Number:
WIPO Patent Application WO/2020/138291
Kind Code:
A1
Abstract:
The present invention relates to: a modified cellulose which is obtained by introducing a modifying group into an anionic group of anion-modified cellulose fiber, and has an average fiber length of 1-500 μm; a dispersion obtained by dispersing the modified cellulose fiber powder in a medium; a resin composition obtained by mixing the modified cellulose fiber powder and a resin; and a resin molded body obtained by molding the resin composition. According to the present invention, it is possible to provide a cellulose fiber powder which has excellent dispersibility in a solvent, and which can be obtained by means of a cheap process, and a method for producing the same.
