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

Abstract: A process for treating cellulosic fibres comprises mechanically pre-treating the fibres followed by treating the fibres with an enzyme and thereafter mixing the fibres with a solution comprising an alkali metal hydroxide followed by mechanically treating the fibres to form microfibrillated cellulose. In this way it is possible to produce microfibrillated cellulose (MFC) in an improved and energy efficient way.
