Abstract
The present invention relates a process to produce microfibrillated cellulose and a microfibrillated cellulose produced according to such process. The fibrillated microfibrillated cellulose is obtained subjecting a cellulose fiber in a slurry of cellulose pulp to multiple mechanical impacts. The cycle may be repeated several times. Non-cutting bars disposed in a ring formation is the preferred method. Two rings concentrically arranged facing each other in high rotation transmit the kinetic energy to the fibers to provide the highly defibrillated microfibrillated cellulose.
