Assignee:

Weyerhaeuser Co. - Federal Way WA
International Classification:

B27N 3/00
US Classification:

264109
Abstract:

A method for making mixed polymer composite fibers in which a carboxyalkyl cellulose and a galactomannan polymer or a glucomannan polymer are blended in water to provide an aqueous solution; the aqueous solution treated with a first crosslinking agent to provide a gel; the gel mixed with a water-miscible solvent to provide fibers; and the fibers treated with a second crosslinking agent to provide crosslinked mixed polymer composite fibers.
