摘要： Individualized, crosslinked fiber, and process for making such fibers. The individualized, crosslinked fibers have between about 0.5 mole % and about 3.5 mole % crosslinking agent, calculated on a cellulose anhydroglucose molar basis, reacted with fibers in the form of intrafiber crosslink bonds, wherein the crosslinking agent is selected from the group consisting of C.sub.2 -C.sub.8 dialdehydes, C.sub.2 -C.sub.8 dialdehyde acid analogues having at least one aldehyde functionality, and oligomers of such C.sub.2 -C.sub.8 dialdehydes, and dialdehyde acid analogues. Preferably, the crosslinking agent is glutaraldehyde, and between about 0.75 mole % and about 2.5 mole % crosslinking agent react to form the intrafiber crosslink bonds. The individualized crosslinked fibers are useful in a variety of absorbent structure applications.

摘要： Absorbent structures having a wetlaid fluid acquisition/distribution layer with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0% NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm.sup.2 ; and a fluid storage layer positioned beneath the aquisition/distribution layer comprising at least about 15% superabsorbent material. The fluid acquisition/distribution layer comprises from about 50% to 100% chemically stiffened cellulosic fibers and from 0% to about 50% binding means.

摘要： Individualized, crosslinked fibers made by (a) defibrating moistened, cellulosic fibers and at least partially drying the fibers under substantially unrestrained conditions, i.e., in the substantial absence of interfiber bonds (b) contacting the fibers with a crosslinking agent, (c) reacting the crosslinking agent with the fibers in the substantial absence of interfiber bonds, to form intrafiber crosslink bonds, (d) subjecting the fibers, while in a moistened condition, to a second defibration step, and then at least partially drying the fibers under substantially unrestrained conditions.
