Title (EN) PROCESS FOR PRODUCING FIBRILLATED CELLULOSE MATERIAL
(FR) PROCÉDÉ DE PRODUCTION DE MATÉRIAU DE CELLULOSE FIBRILLÉE
Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé de production de matériau de cellulose fibrillée. Dans l'invention, la cellulose fibrillée est produite par voie enzymatique en utilisant un mélangeur mécanique à faible besoin en énergie, comme un mélangeur en soc de charrue, pour augmenter la fibrillation. Les enzymes et les conditions de procédé sont choisies de façon à dégrader le moins possible la cellulose, tout en obtenant un haut rendement de nanofibrilles. Les sucres qui sont produits dans le produit final peuvent également être ensuite exploités.
