Abstract
There is provided an expandable absorbent material having superabsorbent in an amount from about 1 to about 75 weight percent and crimped thermoplastic fibers in an amount from about 25 to about 99 weight percent, where said material has a density of from about 0.02 g/cc to about 0.25 g/cc. The superabsorbent may be in the form of particulate, fiber and foam. Such a composite may be used in personal care products like diapers, training pants, absorbent underpants, adult incontinence products, and the like.
