  • Publication number: 20090275906
    Abstract: An absorbent article such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device, wherein at least one part of the absorbent article carries a film having at least one monomolecular layer of a polymer having a functional group and an active agent, in particular to an absorbent article wherein the film is obtainable by layer-by-layer deposition of at least a first polymer having a first functional group and a second polymer having a second functional group capable of interacting with the first functional group. Moreover, the use of a film obtainable by the layer-by-layer deposition of at least one first polymer having a first functional group and a second polymer having a second functional group capable of interacting with the first functional group for releasing an active agent contained in the film upon wetting of the film by body fluids.

  • Publication number: 20090131898
    Abstract: A liquid absorbent open-cell polymeric foam material having properties which makes it suitable for use as an absorbent structure in absorbent articles such as diapers, pant diapers, sanitary napkins, incontinence guards, wound dressings, bed protections etc., at which the foam material has an absorption rate at wetting of at least 0.4 ml/s for a round sample having the diameter 50 mm, a liquid distribution capacity at an inclination of 30° of at least 15 g/g and a liquid storage capacity of at least 9% measured through CRC (centrifuge retention capacity), at which the test liquid in all cases is synthetic urine. There is further referred to an absorbent structure containing the foam material.

  • Patent number: 7396783
    Abstract: A fibrous structure testable in a series of run-off tests, wherein each run-off test includes exposing the fibrous structure to a volume of a test solution and the fibrous structure initially is hydrophobic and has been treated to be hydrophilic, wherein the fibrous structure exhibits a run-off level that is less than 5 percent by weight throughout a series of run-off tests, and wherein the series starts with a first run-off test and ends with a fifth run-off test.

  • Patent number: 6673981
    Abstract: An absorbent porous structure for use in a diaper, a pant diaper, an incontinence guard, a sanitary napkin or the like, with a liquid acquisition portion and a liquid storage portion which are an integrated unit. The liquid acquisition portion comprises a compressed polymeric open-cell foam which expands upon wetting, and the liquid storage portion comprises a polymeric open-cell foam which may be the same or different from the foam in the liquid acquisition portion. The liquid storage portion also contains a superabsorbent material, with the amount of superabsorbent material being lower in the part of the liquid storage portion that is located closest to the liquid acquisition portion than in the part of the liquid storage portion that is located furthest from the liquid acquisition portion. Other embodiments include a method for producing the absorbent structure and an absorbent article containing such an absorbent structure.

  • Patent number: 6657101
    Abstract: The invention refers to an absorbent structure in an absorbent article such as a diaper, a pant diaper, an incontinence guard, a sanitary napkin etc., the absorbent structure comprises an open-cell foam structure, the pore walls of said foam structure comprising a liquid-storing material having the capacity to store more than 7% synthetic urine defined according to the CRC method. The absorbent structure is characterized by that the pores of the foam structure contains hydrophilic fibers, at which at least the main part of the hydrophilic fibers are firmly anchored in the pore walls of the foam structure, and that the fiber amount is at least 10% by weight of the total weight of the open-cell foam in dry condition. The invention also refers to an absorbent article containing such an absorbent structure.
