Microfibril cellulose having cellulose type II crystal structure and molded body containing microfibrillated cellulose

摘要

In order to improve the strength of the resin and the like, microfibrillated cellulose was contained in the resin molded body, but the strength of the resin was substantially the same as that of the resin. For this reason, the present invention is to provide a more expensive resin molded body. By mixing the microfibrillated cellulose having a type II crystal structure obtained by treating the microfibrillated cellulose with an alkaline solution, the resulting product is obtained by mixing ordinary microfibrillated cellulose The tensile strength or bending strength, tensile fracture strain or bending fracture strain and fracture toughness (work amount to fracture) are greatly enhanced as compared with the molded product of the fat.
