Abstract (en)
[origin: WO2024035380A1] Devices used to absorb bodily fluids include, but are not limited to, diapers, incontinence devices, feminine hygiene products, or wound dressings, for example. Certain embodiments of these devices are produced from a top sheet, an absorbent core, and back sheet. Embodiments of the top sheet have a nonwoven polymeric sheet having both water insoluble and water soluble urease inhibiting compounds. The water insoluble and water soluble urease inhibiting compounds may be copper compounds. For example, the nonwoven polymeric top sheet have polymeric fibers and the polymeric fibers include a plurality of first particles of water insoluble copper compounds that release at least one of Cu+ ions and Cu++ ions upon contact with a body fluid embedded in the polymeric fibers and water soluble copper compounds on the surface of the polymeric fibers. The devices also include water insoluble urease inhibiting compounds within the absorbent core.
