摘要： Disclosed is a process for making individualized, crosslinked fibers which includes the steps of providing cellulosic fibers, contacting the fibers with a solution containing a C.sub.2 -C.sub.9 polycarboxylic acid crosslinking agent, mechanically separating the fibers into substantially individual form, drying the fibers and reacting the crosslinking agent with the individualized fibers to form 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.

摘要： Disclosed are absorbent structures containing individualized, crosslinked fibers. The individualized, crosslinked fibers preferably 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 between about 0.5 mole % and about 10.0 mole % crosslinking agent react to form the intrafiber crosslink bonds. Also preferably, the absorbent structures have actual dry densities greater than their corresponding equilibrium wet densities, and expand upon wetting. The absorbent structures may also contain hydrogel-forming material.

摘要： A process for making individualized, crosslinked fibers having low levels of residual crosslinking agent. The fibers are made by contacting the fibers with a crosslinking agent; reacting the crosslinking agent with the fibers to form intrafiber crosslink bonds in the substantial absence of interfiber bonds; and washing the fibers with an alkaline solution.

The individualized, crosslinked fibers have a polymeric polyacrylic acid crosslinking agent reacted with the fibers in the form of intrafiber crosslink bonds. Preferably, the crosslinking agent is a copolymer of acrylic acid and maleic acid and preferably, between about 1.0 weight % and about 10.0 weight % of the crosslinking agent reacts with the individualized fibers to form the intrafiber crosslink bonds. The individualized, crosslinked fibers are useful in a variety of absorbent structure applications. The absorbent structures may also contain hydrogel-forming material.
