Abstract:
An object of the present invention is to provide a cellulose fiber assembly and a cellulose fiber composite, each having low coloration. The present invention is directed to a method for preparing a fibrillated cellulose fiber assembly, in which the cellulose fiber raw materials are subjected to a fibrillation treatment and a reduction treatment. The present invention provides a method for preparing a cellulose fiber assembly, comprising a fibrillation step of fibrillating cellulose fiber raw materials to obtain fibrillated cellulose fibers, an assembly preparation step of obtaining a cellulose fiber assembly using the fibrillated cellulose fibers, and a step of carrying out a reduction treatment. Further, the present invention provides a cellulose fiber composite comprising the prepared cellulose fiber assembly and a matrix material.
