Abstract
A process for treating cellulosic fibers comprising pre-treating the fibers with an enzyme in a first enzymatic treatment followed by mechanical pre-treating the fibers in a first mechanical treatment and a second enzymatic treatment followed by a second mechanical treatment of the fibers to form micofibrillated cellulose. In this way it is possible to produce mircofibrillated cellulose (MFC) in an improved and energy efficient way.
