Abstract: The invention relates to a process for treating cellulosic fibres which process comprises 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 microfibrillated cellulose. In this way it is possible to produce MFC in an improved and energy efficient way.

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.

Abstract: The invention relates to a process for producing microfibrillated cellulose which process comprises providing a slurry comprising cellulosic fibers, treating the slurry with an enzyme, mechanically treating the slurry so that the fibers are disintegrated wherein the mechanical treatment and the treatment with the enzyme is performed simultaneously in a single treatment step. In this way it is possible to produce MFC in an improved and energy efficient way. The invention further relates to microfibrillated cellulose produced according to the process.
