Disclosed is a dean production method for bamboo fibres, comprising the following steps: bamboo pieces are separated into filaments, and the filaments are twisted into ropes to obtain rope-shaped bamboo filaments; the rope-shaped bamboo filaments are refined by means of multiple alternating cold-hot treatments and rolling and rubbing to obtain coarse rope-shaped bamboo fibres (wherein same can be directly put into a drying device and then made into coarse bamboo fibres for a composite material); the coarse rope-shaped bamboo fibres are subjected to continuous biological degumming to obtain the rope-shaped bamboo fibres; the rope-shaped bamboo fibres are fed into a cleaning device for repeated cleaning, rolling and drying are performed, and then spraying-type oiling is performed to obtain thin rope-shaped bamboo fibres; finally, the thin rope-shaped bamboo fibres are subjected to opening and carding to make bamboo fibres for a textile material.

There is provided a device, process and system for decortication of biomass comprising hurd, bark and bast, such as long stalk biomass. Typically, one or more of the bark, hurd or bast generated by the decortication process or decorticator device is fed to a downstream process or downstream device such as a counter current extractor. The liquid or fibre products of decorticator, or the decorticator in combination with the counter current extractor may be further processed into their components.

A method of producing a fine fiber, including treating a cellulose raw material with an enzyme; and fibrillating the treated cellulose raw material; treating with the enzyme under a condition where at least a ratio of endo-glucanase activity to cellobiohydrolase activity that is 0.06 or greater. The cellulose raw material may be a plant fiber. The method efficiently produces a fine fiber from a cellulose raw material at low cost and with a low environmental burden, a fine fiber, and a non-woven fabric.

Nanocellulose-reinforced cellulose fibers can increase the strength of hardwood fibers or agricultural-residue cellulose fibers, to simulate the strength of softwood fibers in pulp or pulp products (including composites). In some variations, the invention provides a method of reinforcing cellulose fibers, comprising providing cellulose fibers derived from hardwoods, agricultural residues, or a combination thereof; providing a source of nanocellulose comprising cellulose nanofibrils and/or cellulose nanocrystals; and reinforcing the cellulose fibers with the nanocellulose to increase strength of the cellulose fibers. In some embodiments, the nanocellulose is obtained from fractionating biomass in the presence of an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a liquid phase; and then mechanically refining the cellulose-rich solids to generate the nanocellulose.
