Bleached polyacrylic acid crosslinked cellulosic fibers, methods for making the fibers, and products including the fibers. The bleached polyacrylic acid crosslinked cellulosic fibers are polyacrylic acid crosslinked cellulosic fibers that have been treated with one or more bleaching agents to provide crosslinked cellulosic fibers having improved whiteness.

An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.

A method for making bleached crosslinked cellulosic fibers having high color and brightness properties is disclosed. In the method cellulosic fibers which have been with a crosslinking agent in the presence of a polyol are treated with a bleaching agent to yield cellulosic fibers with high color and brightness.

A unitary absorbent composite having a plurality of strata is disclosed. In the composite, adjacent strata are separated by a transition zone integrally connecting the strata. Each stratum includes fibers and a binder, and the transition zone includes fibers from adjacent strata. Method for forming the unitary composite are also disclosed.
