Abstract (en)
[origin: WO2013072564A1] The invention relates to a method for manufacturing furnish for a paper product, wherein the manufactured furnish contains fibril cellulose material. The method comprises introducing first raw material to a system, which first raw material includes cellulose pulp (2), introducing second raw material to the system, which second raw material comprises cellulose fibers that are oxidized by nitroxyl-mediated oxidation of hydroxyl groups of the cellulose, conveying the first raw material and the second raw material to a refiner (8), and refining and mixing the first raw material and the second raw material in the refiner (8) in order to produce furnish comprising fibril cellulose material (4). In addition, this invention relates to a system for manufacturing furnish and to a paper product.
