ABSTRACT:
The present invention relates to the production of texturized microcrystalline cellulose from raw pulp material. This texturized microcrystalline cellulose can then be used for surface treatment of paper or paper board. Additionally, the texturized microcrystalline cellulose may be used as a starting material for production of paper or paper board.
