Abstract: The present invention relates to foam. In particular, the present invention relates to profiled foams and processes for profiling absorbent foam products. More particularly, the present invention relates to processes for producing a profiled absorbent polyurethane foam product, comprising the steps of foaming, curing, profiling and drying, wherein profiling occurs before drying; and absorbent aliphatic polyurethane foam products having at least one profiled surface.

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.

Abstract: A device (1) for causing the displacement of a piston (36) or diaphragm (4) comprising an enclosure containing unsaturated super-absorbent material (38) and including a piston or diaphragm; and a fluid inlet into the enclosure adapted to allow fluid into the enclosure and restrain the super-absorbent material form escaping from the enclosure; such that as fluid is allowed into the enclosure, it is absorbed by the super-absorbent material which swells against the piston (36) or diaphragm (4), causing displacement thereof. The piston (36) or diaphragm (4) may form at least one wall of the enclosure. Alternatively diaphragm may be a membrane of elastomeric material within the enclosure. The invention may be used in a drug delivery system, a air freshener, or a lavatory cleaner.
