  • Patent number: 8604129
    Abstract: A sheet material that includes an elastic component or material (e.g., film, nonwoven web laminated to the elastic component, etc.) is provided. The elastic component is formed from a styrenic block copolymer composition containing from about 10 wt. % to about 90 wt. % of styrene-butadiene-styrene block copolymer; and from about 10 wt % to about 90 wt. % of styrene-isoprene/butadiene-styrene block copolymer. The styrenic block copolymer composition has good viscosity stability during extrusion and thus may be readily formed into an elastic sheet material. The elastic sheet material may be subsequently crosslinked to achieve the desired elastic and mechanical properties.

  • Publication number: 20130231623
    Abstract: A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid.

    Abstract: The present invention relates to an absorbent structure, preferably for use in absorbent products, such as used in the food, consumer, household, building and construction, beauty and medical industry, and as used in the personal hygiene industry. The substantially cellulose free absorbent structures continuously immobilise absorbent polymer material via initial smaller pockets and subsequently larger compartments allowing excellent fluid management of the absorbent polymer material in dry, partially and fully liquid loaded state. Preferably such absorbent structure volume increases are result of temporary secondary attachment patterns made in combination with substantially permanent primary attachment grids allowing the release of bigger volumes from the initial smaller volumes by detachment of the secondary attachments.
