摘要： Processes disclosed are capable of converting biomass into high-crystallinity nanocellulose with surprisingly low mechanical energy input. In some variations, the process includes fractionating biomass with an acid (such as sulfur dioxide), a solvent (such as ethanol), and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; and mechanically treating the cellulose-rich solids to form nanofibrils and/or nanocrystals. The total mechanical energy may be less than 500 kilowatt-hours per ton. The crystallinity of the nanocellulose material may be 80% or higher, translating into good reinforcing properties for composites. The nanocellulose material may include nanofibrillated cellulose, nanocrystalline cellulose, or both. In some embodiments, the nanocellulose material is hydrophobic via deposition of some lignin onto the cellulose surface. Optionally, sugars derived from amorphous cellulose and hemicellulose may be separately fermented, such as to monomers for various polymers. These polymers may be combined with the nanocellulose to form completely renewable composites.

摘要： Described herein is nanocellulose produced by introducing a mixture of cellulose based fiber raw material and water through a refining gap, having a width smaller than 0.1 mm. In the refining gap, the fiber raw material is subjected to processing forces varying in the direction of introducing said mixture, by means of refining zones provided in the gap one after each other in the feeding direction, whereby the refining surfaces differ in surface patterning and/or surface roughness. The mixture of fiber raw material and water is guided past the refining surfaces in the feeding direction to different locations in the refining zone by by-pass channels provided in the stator. The width of the refining gap is maintained by the combined effect of the feeding pressure of the mixture of fiber raw material and water fed into the refining gap and the axial force of the rotor.

摘要： The invention relates to a method for processing an aqueous gel of nanofibrillar cellulose by removing water from the aqueous gel by means of an organic solvent miscible with water. In the method: aqueous gel is introduced into a volume of organic solvent miscible with water in a controlled manner so that the aqueous gel is kept as a separate phase and forms discrete physical entities containing the nanofibrillar cellulose within the phase; water is changed with the organic solvent in said discrete physical entities of nanofibrillar cellulose; and the physical entities are separated from the volume of organic solvent.

摘要： A method of making a multi-ply wiper/towel product with cellulosic microfibers. The method includes compactively dewatering a nascent web that includes at least about 10% fibrillated cellulosic microfibers and has an apparently random distribution of fibers. The dewatered web having the apparently random distribution of fibers is applied to a transfer surface. The web is belt-creped from the transfer surface utilizing a creping belt. The belt-creping step occurs under pressure in a belt creping nip defined between the transfer surface and the creping belt. The web is dried to form a dried web having a plurality of fiber-enriched hollow domed regions protruding from an upper side of the dried web. The hollow domed regions have a sidewall of a relatively high local basis weight formed along at least a leading edge thereof. The web also has connecting regions of a relatively lower local basis weight forming a network interconnecting the hollow domed regions of the dried web, and transition areas provided with upwardly and inwardly inflected consolidated fibrous regions that transition from the connecting regions into the sidewalls of the hollow domed regions formed along at least the leading edge thereof.
