METHOD OF PRODUCING CELLULOSE NANOFIBRILS

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 n...

Beschreibung
Zusammenfassung:	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. La présente invention concerne un procédé de production de nanofibrilles de cellulose comprenant les étapes consistant à : identifier un niveau souhaité de pureté de la pâte de cellulose nanocristalline, raffiner partiellement la pâte pour produire une pureté de pâte de cellulose nanocristalline entre 5 % et 15 % inférieure à la pureté souhaitée, puis séparer les nanofibrilles de cellulose des fibres plus longues pour produire le niveau voulu de pureté de pâte de cellulose nanocristalline.
