摘要： A cellulose nanofibrils production method comprising the steps of: identifying a desired level of cellulose nanofibrils pulp purity, partially refining pulp to produce a cellulose nanofibrils pulp purity between 5% and 15% less than the desired desired purity, and then separating out the cellulose nanofibrils from the longer fibers to produce the desired level of cellulose nanofibrils pulp purity.
