PROCESS FOR PRODUCING MICROFIBRILLATED CELLULOSE |
摘要 |
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.
