Abstract: The invention relates to a process for treating cellulosic fibres which process 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 MFC in an improved and energy efficient way.
