ABSTRACT:
Disclosed are individualized, crosslinked fibers, and process for making such fibers. The individualized, crosslinked fibers have a C.sub.2 -C.sub.9 polycarboxylic acid crosslinking agent reacted 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 applications.
