Abstract
A fibrous cellulose having a high resin reinforcing effect and a method for manufacturing the same, and a fibrous cellulose composite resin having high strength and a method for manufacturing the same. A fibrous cellulose has an average fiber width of 0.1 μm or more, an average fiber length of 0.02 to 3.0 mm, and a fibrillation ratio of 1.0% or more. A kneaded product of this fibrous cellulose and a resin is formed into a fibrous cellulose composite resin. In manufacturing the fibrous cellulose, a raw material fiber is defibrated so as to have an average fiber width of 0.1 μm or more, an average fiber length of 0.02 to 3.0 mm, and a fibrillation ratio of 1.0% or more. The fibrous cellulose obtained by this method and a resin are kneaded to manufacture a fibrous cellulose composite resin.
