  • Patent number: 11413197
    Abstract: The present invention relates to acquisition layers for use in absorbent articles, preferably of the disposable personal hygiene type. It discloses absorbent articles (7) comprising a liquid permeable topsheet (8), a liquid impermeable backsheet (9), an absorbent core (1) between the topsheet (8) and the backsheet (9) and an acquisition layer (2) between the topsheet (8) and the absorbent core (1), said acquisition layer (2) having a width (w) and a length (l) along an acquisition plane and a thickness (t) extending perpendicular thereto. The absorbent core (1) comprises at least one absorbent material selected from the group consisting of fibrous absorbent materials and highly absorbent polymers.

  • Publication number: 20220160553
    Abstract: The present invention relates to absorbent cores for use in absorbent articles, preferably of the disposable personal hygiene type. It discloses absorbent cores comprising a foam layer incorporating a nonwoven fabric and having a top surface and a bottom surface, said foam layer top surface comprising one or more indented compressed portions and one or more raised non-compressed portions. The foam layer has openings extending through the foam and the nonwoven fabric. The absorbent core further comprises, joined to the bottom surface of the foam layer, a nonwoven comprising superabsorbent polymers. Absorbent cores of the present invention provide a fast acquisition of body exudates and a good liquid retention capacity. This is further achieved in a simple and cost-effective way without complex and considerable foam formulation and processing requirements.

  • Patent number: 11007094
    Abstract: An absorbent core for an absorbent article, the absorbent core comprising at least two layers, each layer having a width w and a length l along a first plane and a thickness t extending perpendicular thereto, wherein the layers are arranged in facing relationship along the first plane, and wherein the layers comprise a polymeric foam having an open cell and interconnected porous structure. The first and second layers comprise an anisotropic cell structure having an axis of anisotropy extending substantially parallel to a longest length of a plurality of substantially neighbouring cells. The axis of anisotropy of the second layer extends substantially perpendicular to said thickness t and parallel to said first plane and the axis of anisotropy of the first layer is substantially perpendicular to the axis of anisotropy of the second layer.
