摘要:
The present invention provides a novel production method of a cellulose nanofiber and a novel cellulose nanofiber. The method for producing a cellulose nanofiber comprises defibrating pulp by a single- or multi-screw kneader in the presence of water, the single or multi-screw kneader having a screw circumferential speed of 45 m/min. Or more.
