    Abstract: A bandage for covering a wound treated with an allograft can include a liquid permeable skin adherent layer having a wound facing surface with an adhesive thereon for adhering to skin proximate the wound. A compressible support section can be supported by the skin adherent layer for maintaining the allograft in place on the wound, and an absorbent section can be positioned over the compressible support section. The absorbent section can be comprised of a liquid absorbent material and can aid in keeping the allograft hydrated. The compressible support section can be positioned intermediate the skin adherent layer and the absorbent section. A liquid permeable covering layer can be positioned over the absorbent section, and attached to the skin adherent layer.

  • Patent number: 8524355
    Abstract: A disposable absorbent article includes an absorbent mat provided between a liquid-permeable top sheet and a liquid-impermeable back sheet. Herein, the absorbent mat includes a sheet-like water-absorbent layer that contains a water-absorbent resin powder but that does not contain pulp fibers, and a fiber assembly layer that contains both the water-absorbent resin powder and the pulp fibers, the sheet-like water-absorbent layer and the fiber assembly layer arranged sequentially in this order from a top sheet side. The fiber assembly layer includes a fiber presence region in which both the pulp fibers and the water-absorbent resin powder are present, and a fiber absence region in which both the pulp fibers and the water-absorbent resin powder are absent, the fiber presence region and the fiber absence region formed to be adjacent with each other.

  • Publication number: 20130204218
    Abstract: A modified kraft pulp fiber with unique properties is provided. The modified fiber can be a modified bleached kraft fiber that is almost indistinguishable from its conventional counterpart, except that it has a low degree of polymerization (DP). Methods for making the modified fiber and products made from it are also provided. The method can be a one step acidic, iron catalyzed peroxide treatment process that can be incorporated into a single stage of a multi-stage bleaching process. The products can be chemical cellulose feedstocks, microcrystalline cellulose feedstocks, fluff pulps and products made from them.
