  • Publication number: 20030234468
    Abstract: An absorbent material is provided with improved characteristics. A process is provided for making the absorbent material. A web is formed with at least one layer of absorbent material, and it may include a mixture of cellulosic fibers and superabsorbent material. The moisture content of the web is increased so as to increase the web density. Then, the web is compacted at an elevated temperature to further increase the web density and preferably to also effect hydrogen bonding within the web. In one embodiment a tissue layer is provided, is wetted with water, and is bonded to the layer of absorbent material.

  • Publication number: 20010031358
    Abstract: An absorbent material that can be used as an absorbent core in absorbent articles such as disposable diapers, feminine hygiene products and incontinence devices is provided. An absorbent material of this invention contains cellulosic fibers at least a portion of which cellulosic fibers have a relative crystallinity of less than about 65 percent. The absorbent material has superior absorptive, strength, and suppleness properties when compared to existing core materials. The material can be air-laid in one or more layers.
