ABSTRACT:
A method for making a fibrous composite, comprising blending a carboxyalkyl cellulose and a galactomannan polymer or a glucomannan polymer in water to provide an aqueous solution; treating the aqueous solution with a first crosslinking agent to provide a gel; drying the gel to provide a solid; comminuting the solid to provide a plurality of particles; combining at least a portion of the plurality of particles with an aqueous suspension comprising cellulose treated with a galactomannan polymer or a glucomannan polymer, and optionally a second crosslinking agent, to provide a mixture; and mixing the mixture with a water-miscible solvent to provide a fibrous composite.
