Abstract:
The present invention relates to an absorbent member comprising fine particles of chitosan material, in particular water-soluble chitosan salt, for improved fluid retention and leakage prevention, and a process for making such an absorbent member.
Abstract:
A disposable absorbent article (20) which is substantially flat prior to use for wearing adjacent a body discharge area having a longitudinal centreline (0-0) and a lateral centreline (A-A) orthogonal thereto, and defining longitudinal and lateral directions respectively. The disposable absorbent article further having a liquid pervious topsheet (24), a backsheet (25) joined to said topsheet, and an absorbent core (28) intermediate the backsheet and the topsheet. The absorbent core includes a member for expanding (46) the article into a tridimensional structure while being worn by a user. The article further includes a shrinkable member (48) for inducing forming or bending of the article in combination with the expanding member (46). Both expanding and shrinkable members (46, 48) are activatable by body fluids.
Abstract:
A disposable absorbent article (20) which is substantially flat prior to use for wearing adjacent a body discharge area having a body facing surface and a garment facing surface. The disposable absorbent article comprises a liquid pervious topsheet (24), a backsheet (26), and an absorbent core (28) intermediate the topsheet (24) and the backsheet (26). The absorbent core (28) has a body facing surface and a garment facing surface and comprises an expanding layer for expanding the article into a tridimensional structure while being worn by a user. The expanding layer is activated by body fluids, and comprises incisions (48) on its body facing surface and/or on its garment facing surface, and apertures (49) on its body facing surface and/or on its garment facing surface.

Abstract:
The present invention relates to an airlaid sheet material comprising a dry laid fibrous web and a latex coating on both surfaces thereof in selected amounts. The airlaid sheet material can be an absorbent structure for absorption of fluids.
Abstract:
The present invention relates to the field of absorbent articles for personal hygiene. Specifically, the present invention provides a multicomponent material, which is comprised of chitosan material being coated onto an inert carrier material. The multicomponent material of the present invention provides the opportunity to incorporate chitosan material in products, especially absorbent articles for personal hygiene, in a very defined and cost-effective manner. Absorbent articles comprising the multicomponent material of the present invention are also introduced herein.

The disposable absorbent article (20) includes a liquid pervious topsheet (24), a backsheet (26) joined to said topsheet (24) and an absorbent core (28) intermdiate the backsheet (26) and the topsheet (24). The absorbent core (28) includes an expanding layer (46) for expanding the article into a tridimensional structure while being worn by a user. The expanding layer (46) is activated by body fluids and has a constant thickness in the dry state prior to use. The expanding layer (46) is capable, upon full activation by body fluids, of expanding into a predetermined profile of non-constant thickness.
Abstract:
An absorbent core comprising super absorbent polymer particles and a pattern of adhesive for use in disposable absorbent articles, for example for the absorption of menses or blood.
Abstract:
Absorbent core for disposable absorbent articles, particularly for the absorption of menses or blood, comprising a relatively high amount of absorbent gelling material and a cationic polysaccharide.
