Title:
FIBROUS CELLULOSE, FIBROUS CELLULOSE DISPERSION LIQUID, AND FIBROUS CELLULOSE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/241680
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a microfibrous cellulose capable of exhibiting excellent coating suitability when added to a paint. The present invention pertains to a fibrous cellulose having a fiber width of at most 1,000 nm, wherein when the fibrous cellulose is dispersed in a dispersion solvent containing water and isopropanol to obtain a dispersion liquid having a mass ratio of water to isopropanol of 7:3 and a viscosity at 23°C of 2,500 mPa·s, and the dispersion liquid is stirred under predetermined stirring conditions, a viscosity change rate calculated by the following expression is within ±50%. Viscosity change rate (%)=(viscosity after stirring-viscosity before stirring)/viscosity before stirring×100
