    摘要: Cellulose precursor materials may be refined (e.g., fibrillated) in an ethanol medium, or other solvent medium, instead of water. Following refining, the solvent may be removed and recycled prior to incorporation into another material, or optionally, following such incorporation. The solvent may assist the incorporation of nanocellulose into another material (e.g., a polymer) for a composite, for example. In some variations, a process comprises fractionating a biomass feedstock in the presence of an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; mechanically treating the celluloserich solids, in the presence of a refining solvent, to form cellulose fibrils and/or cellulose crystals, thereby generating a nanocellulose material; recovering and recycling the refining solvent; and recovering the nanocellulose material or incorporating the nanocellulose material into a composite material.

Water is removed from the washed raw material in a pulp thickener (4), and the pulp is refined in at least one refiner (6) comprising at least a first blade and a counter piece, wherein the distance between the first blade and the counter piece determines the blade gap. In the method, the raw material is also pre-defibrated by at least one pre- defibrator (3) before the refining of the pulp in the refiner (6). The invention also relates to a system for producing mechanical pulp from cellulose-based raw material. The system comprises a washer (2), a pulp thickener (4), and at least one refiner (6) comprising a refining space and at least a first blade and a counter piece, wherein the distance between the first blade and the counter piece determines the blade gap. The system comprises a pre-defibrator (3) placed before the refiner (6). The invention also relates to the use of the method and the system in the manufacture of a paper product.

    摘要: The invention relates to pulp treatment by pulp fractionation such that the pulp is fractionated into a short fiber fraction and a long fiber fraction, wherein the short fiber fraction bypasses the refiner and the long fiber fraction is mechanically treated in the refiner, whereafter the untreated short fiber fraction and the mechanically treated long fiber fraction are mixed together or are used separately for paper production. By this fiber fractionation before refining fiber lengths distribution is optimized in order to maximize the strengths properties and to minimize the fines content. According to this mode the long fiber fraction will have a mechanical treatment which is more effective.

    摘要: A process for making fibrillated fibers includes preparing a fluid suspension of fibers, low shear refining the fibers at a first shear rate to create fibrillated fibers having a reduced CSF, and subsequently higher shear refining the fibers at a second shear rate, higher than the first shear rate, to increase the degree of fibrillation of the fibers. The refining at the first shear rate may be with a rotor at a first maximum shear rate and the refining at the second shear rate may be with a rotor at a second maximum shear rate, higher than the first maximum shear rate. The process may further include pre-treating the fibers by high shear refining with impact to stress the fibers prior to low shear refining.
