WIPO Patent Application WO/2023/162433
Kind Code:
A1
Abstract:
[Problem] To provide fibrous cellulose having a high resin reinforcing effect, a high-strength fibrous cellulose composite resin, and a method for producing fibrous cellulose having a high resin reinforcing effect. [Solution] This fibrous cellulose has an average fiber width of 0.1-20 μm, wherein part or all of hydroxy groups are substituted by carbamate groups, the rate of substitution by carbamate groups is 0.5 mmol/g or more, and fine ratio A/fine ratio B is 1.5-10. This fibrous cellulose composite resin contains said fibrous cellulose and a resin. In production of the fibrous cellulose, a disc refiner is used for miniaturization, and the initial load factor of the disc refiner is set to 65% or more.
