A method for manufacturing an absorbent article including a liquid permeable layer, a liquid impermeable layer, and an absorbent layer, includes a step for forming a functional composition by mixing water-disintegrable microcapsules containing a volatile functional component with a solvent capable of keeping the functional component as contained in the microcapsules, a step for coating the functional composition on at least a portion of a surface of a layer to be coated to form a functional composition-coated region on the surface to be coated, and a step for stacking the liquid permeable layer, and the absorbent layer and the liquid impermeable layer with an adhesive-coated region coated with an adhesive interposed therebetween.

The present invention relates to a disposable absorbent article that can be fully compostable, wherein such article contains, as sole absorbent material, one or more silicon-based products selected from: hydrated aluminosilicates and fumed silica, optionally in combination with other silica-based compounds and/or natural silica, processes for the preparation of such article and for the preparation of said absorbent material.

A diaper comprising a biodegradable top sheet, a biodegradable absorbent core and a biodegradable bottom sheet, wherein the bottom sheet is liquid impervious and wherein the top sheet is configured for transmission of bodily fluids to the absorbent core. The absorbent core comprises a first and a second non-woven layer comprising pulp fibers, and in between thereof a composting-stimulating layer comprising charcoal.

Adhesive compositions are described which include one or more gelling agents in combination with one or more non-gelling disintegrants. The adhesive compositions exhibit relatively high fluid handling capacities and static absorption properties, thus enabling their use in a wide range of medical applications. Various adhesive articles such as dressings and related methods of use are also described which utilize the adhesive compositions. In preferred embodiments the adhesive component is an acrylic adhesive, the gelling agent is selected from the group consisting of (i) carboxymethyl cellulose, (ii) superabsorbent polymer, and (iii) combinations of (i) and (ii), and the non-gelling disintegrant is selected from the group consisting of (i) fully pregelatinized potato starch, (ii) microcrystalline celluloseand (iii) combinations of any of (i)-(ii).

A novel bio-based superabsorbent polymer material based on a proteinaceous natural polymer is introduced herein. There is further disclosed a method for the manufacture of such a bio-based crosslinked superabsorbent polymer material. The method includes, but not limited to, introducing polymerizable unsaturated groups onto the natural polymer or its derivative so as to yield a macromonomer. The macromonomer can be formed by covalently binding unsaturated carbon-carbon double bonds to a proteinaceous substrate through a reaction of a selected chemical compound and the amino group on the proteinaceous substrate. The macromonomer is then copolymerized with unsaturated co-monomer(s) to form a crosslinked superabsorbent material.

A biodegradable, disposable absorbent article, such as a diaper, having a non-woven inner layer of natural fibers and a non-woven outer layer of natural fibers and a treatment applied to at least one surface thereof. The treatment includes at least one compound selected from the group consisting of waxes, urethanes, silicones, fluorocarbons, and non-fluorochemical repellents. The absorbent article has a core of natural fibers or fibrous material, and optionally polyacrylate superabsorbent particles, positioned between the inner layer and the outer layer. The article may contain polylactic acid films between the layers.
