A method for preparing a fibrous material of crosslinked dialdehyde microfibrillated cellulose by spinning

A method is provided for preparing a fibrous material of crosslinked microfibrillated cellulose. Dialdehyde microfibrillated cellulose is spun into a fibrous material; and then said fibrous material is post-treated (by reduction of pH) to provide crosslinking between the dialdehyde microfibrillated...

Zusammenfassung:	A method is provided for preparing a fibrous material of crosslinked microfibrillated cellulose. Dialdehyde microfibrillated cellulose is spun into a fibrous material; and then said fibrous material is 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.
