Document Type and Number:
WIPO Patent Application WO/2015/080335
Kind Code:
A1
Abstract:
The present invention relates to a method for producing nanofibrillated cellulose, which allows the production of excellent cellulose nanofibrils through a simple process without an enzymatic treatment step as in the conventional art, in a manner where a cellulose aqueous dispersion is homogenized by adding an alkaline aqueous solution having a pH between 8 and 14 so that the alkaline aqueous solution aids the swelling of an amorphous region of cellulose, thereby promoting fibrillation of cellulose during the homogenizing process.
