networked cellulosefasern, a faserbahn, an absorbing product and process for increasing the strength of composites with hochbauschigen fibres

摘要

Crosslinked cellulose fibers having free pendant carboxylic acid groups are disclosed. The fibers include a polycarboxylic acid covalently coupled to the fibers, and are crosslinked with a crosslinking agent having a cure temperature lower than the cure temperature of the polycarboxylic acid. Methods for producing the fibers and for producing a fibrous sheet incorporating the fibers are also disclosed.
