  • Publication number: 20030219573
    Abstract: An absorbent product, such as a panty liner, a sanitary towel, an incontinence protection or a tampon for absorption of urine, blood or menstrual fluid, comprising a fluid permeable surface layer facing the wearer during use, a fluid impermeable backing layer facing away from the wearer during use, and an absorbent body, positioned between the surface and backing layers, the absorbent body includes superabsorbent polymers (SAP). The SAP-material includes at least two variants, the first variant is a SAP with a cross-linking degree in the interval from 0.02 to 2.0%, and the second variant is a SAP with a cross-linking degree in the interval from 3.0 to 7.0%. An absorbent product is provided which is especially adapted for absorption of both blood and urine, the SAP low cross-linking degree being suitable for absorption of water, and the SAP of high cross-linking degree being suitable for absorption of blood-containing fluids.

  • Publication number: 20030139716
    Abstract: An absorbent product, such as a panty liner, a sanitary towel, an incontinence protection, a dressing, or a tampon for absorption of blood or menstrual fluid, includes a liquid permeable surface layer facing the wearer during use, a liquid impermeable backing layer facing away from the wearer during use, and an absorbent body with one or more material layers, positioned between the backing layer and the surface layer. The absorbent body includes super-absorbent polymers (SAP), the SAP material has a contact angle smaller than 60°, as measured with defibrinated sheep blood, and the SAP material has a gel-strength which is higher than 18 kPa. Hereby, a very good absorption of blood-containing liquids is obtained.
