Beschreibung
Zusammenfassung:	The present disclosure relates to a method for consolidating a fibrous material comprising or consisting of, plant-based fibers, such as cellulose fibers and/or poly-lactic acid fibers, the method comprising the steps of; - applying to the fibrous material an aqueous solution comprising a cellulose derivative, and/or a salt thereof, and an acid, the aqueous solution having a pH within the range of from 3 to 7, optionally within the range of from 3 to 6, optionally within the range of from 3 to 4.5; and - drying the bonded fibrous material, optionally at 100⁰ C or higher. The present disclosure relates to a fibrous material formed by the method, an aqueous binder solution comprising a cellulose derivative, and/or a salt thereof, and an acid, and a nonwoven material comprising airlaid plant-based fibers being consolidated by a bio- based binder in the presence of a carboxylic acid, the bio-based binder being a cellulose derivative, and/or a salt thereof.
