The present invention provides for a process for producing dry, water-dispersible, non-surface modified nanocellulose particles or a powderous composition r comprising said particles comprising the steps of:

Supercritical CO2 cellulose spraydrying

A low energy method for the preparation of nanocellulose using selected organic or inorganic swelling agents. The use of these swelling agents allows opening up the intercrystalline structure and partially the intracrystalline structure of cellulosic materials thereby achieving a reduction 5 in the energy required to subsequently process the resultant swollen cellulose material into nanocellulose.

Low energy method for the preparation of non-derivatized nanocellulose

The present invention is directed towards a method for spinning anionically modified cellulose comprising the steps of: (a) preparing a suspension of the anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension through a spinneret into a spinbath comprising a cationic complexing agent, and (d) isolating the sun fibers from the spin bath; as well as fibers obtained based on the method of the invention and paper or board products derived from such fibers.

Method for spinning anionically modified cellulose and fibres made using the method

The present invention is directed towards a method for spinning neutral or anionically modified cellulose comprising the steps of: (a) preparing a suspension of the neutral or anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension into an airgap region comprising at least one heated zone to obtain spun fibers, (d) subjecting the spun fibers to at least one washing stages and (e) isolating the spun fibers from the at least one washing stages; as well as fibers obtained based on the method of the invention and paper or board products derived from such fibers.
