Abstract: A method is provided for preparing a fibrous material of crosslinked microfibrillated cellulose. Dialdehyde microfibrillated cellulose is spun into a fibrous material; said fibrous material is pre- or post-treated (by reduction of pH) to provide crosslinking between the dialdehyde microfibrillated cellulose. Fibrous materials such as filaments or mats, and polymer composites comprising such materials are also described.

Abstract: A method is provided for preparing a film of crosslinked microfibrillated cellulose. Phosphorylated microfibrillated cellulose is cast or wet-laid into a film; and then said film is post-treated (e.g. by heat-treatment) to provide crosslinking between the phosphorylated microfibrillated cellulose. Films and hygiene products comprising such films are also described.
