Title:
METHOD FOR PRODUCING CELLULOSE NANOFIBER DISPERSION
Document Type and Number:
WIPO Patent Application WO/2019/176465
Kind Code:
A1
Abstract:
This method for producing a high-transparency cellulose nanofiber dispersion has a preliminary defibration step for beating chemically modified cellulose using a single disk-type refiner, and a main defibration step for defibrating pulp obtained in the preliminary defibration step through treatment by a high-pressure disperser at a treatment pressure of 1-400 MPa.
