  • Reticulated absorbent composite
    Publication number: 20030139718
    Abstract: An absorbent composite having a reticulated core and a fibrous stratum is disclosed. The core and stratum are integrally formed, and the stratum is coextensive with a surface of the core. In one embodiment, the composite includes strata on opposing surfaces of the core. The core includes a fibrous matrix and absorbent material. The fibrous matrix defines voids and passages between the voids, which are distributed throughout the composite. Absorbent material is located within some of the voids. On wetting, absorbent material located in these voids is expandable into the void. Methods for forming the composite and absorbent articles that include the composite are also disclosed.
