Abstract
An object of the invention is to provide cellulose fibers which can give a cellulose composite that renders high transparency, a reduction in linear expansion coefficient, and a high modulus of elasticity possible. The invention relates to: a process for producing modified cellulose fibers which includes a modification reaction step of reacting cellulose with an aromatic compound in an organic acid to thereby modify the cellulose with an aromatic-ring-containing substituent; cellulose fibers modified with aromatic-ring-containing substituent; a dispersion of the cellulose fibers; and a cellulose fiber composite obtained from the same.
