    摘要: An absorbent structure expands to a greater extent along one surface than along an opposite surface when in the presence of a liquid. The absorbent structure may include a single layer, or two or more layers intimately bonded to one another. When in the presence of a liquid, the more expandable surface causes an increase in concavity in the X-Y plane of the structure, with the concavity being in the direction of the less expandable surface. One or both surfaces can be treated to adjust the respective level of expandability. By inducing a formed shape upon hydration swelling, a trough shape can be generated to facilitate absorbent properties, containment, and fit. The invention includes absorbent articles having such an absorbent structure incorporated therein.

    摘要: A process for making an absorbent composite including absorbent fibers, superabsorbent polymer and, optionally, thermoplastic fibers and other ingredients is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent composite. Specifically, the polymerization of superabsorbent is initiated from within a plurality of absorbent and/or thermoplastic fibers, which are then formed into a web. The integrated process eliminates the need for separate manufacture of superabsorbent polymer prior to the fiber forming and web forming processes. Also, the superabsorbent polymer thus formed tends to disperse better and remain adhered to the absorbent and/or thermoplastic fibers, providing a stable and uniform absorbent composite for various end use applications.
