Individualized, polycarboxylic acid crosslinked fibers.
Disclosed are individualized, crosslinked fibers, and process for making such fibers. The individualized, crosslinked fibers have a C2 - C9 polycarboxylic acid crosslinking agent reached with the fibers in the form of intrafiber crosslink bonds. Preferably, the crosslinking agent is citric acid, and preferably, between about 0.5 mole % and about 10.0 mole % of the crosslinking agent reacts to form the intrafiber crosslink bonds. The individualized, crosslinked fibers are useful in a variety of absorbent structure application.
