    Research output: PatentPatent


    The present invention relates to a process for producing a fibrillated cellulose material. In the invention fibrillated cellulose is produced enzymatically by using a low energy demanding mechanical mixer such as plough share mixer, to enhance the fibrillation. Enzymes and process conditions are chosen so that the cellulose degradation is as low as possible, while obtaining a high yield of nanofibrils. Sugars that are produced into the end-product may also be furthermore exploited.
