Abstract

See full text

The present invention relates to a process for producing a nanocellulosic material based on the use of fractioning of cellulosic pulp stream from pre-treatment or mechanical defibrillation (partially refined/defibrillated pulp) in combination with stages of mechanical defibrillation, in which both the accept fraction and the reject fraction can be conveyed to stages of consistency adjustments so as to precede another distinct defibrillation stage. For example, if the accept is conveyed to a consistency adjustment preceding a second defibrillation stage while the reject is conveyed to the other independent stage of consistency adjustment to return to the first stage of mechanical defibrillation.
