Document Type and Number:
WIPO Patent Application WO/2022/209157
Kind Code:
A1
Abstract:
[Problem] To provide: a fibrous cellulose-containing product having excellent dispersibility even when being dried; a production method for the fibrous cellulose-containing product; and a fibrous cellulose composite resin having excellent strength. [Solution] This product contains a fibrous cellulose and is to be added to a resin. The fibrous cellulose has average fiber width of 0.1-19 μm. A hydroxyl group in the fibrous cellulose is substituted with a carbamate group. A powder that interacts with the fibrous cellulose is contained in the product. In addition, this fibrous cellulose composite resin uses the fibrous cellulose-containing product as fibrous cellulose. Furthermore, this production method for a fibrous cellulose-containing product involves: defibrating, into an average fiber width of 0.1-19 μm, fibrous cellulose in which a hydroxyl group is substituted with a carbamate group; mixing the fibrous cellulose with a powder that interacts with fibrous cellulose to obtain a liquid mixture; and drying the liquid mixture.
