A sanitary napkin for women includes a permeable inner sheet, which comes into contact with the skin of a wearer to thus allow secretions to pass therethrough, an outer sheet fused to the inner sheet, and an absorption pad disposed between the inner sheet and the outer sheet to absorb the secretions passed through the inner sheet, the outer sheet being a nanolaminate film composed of a nanomembrane formed by electrospinning a polymer solution and a strength-reinforcing nonwoven fabric laminated on one side of the nanomembrane.

A tackifier-free, hot melt adhesive composition comprises an amorphous, single site-catalyzed, high molecular weight propylene copolymer, preferably with a weight average molecular weight (M.sub.w) greater than 80,000 g/mol; a semicrystalline, single site-catalyzed, low molecular weight propylene copolymer, preferably with an M.sub.w less than 60,000 g/mol; and polyisobutene. The composition may optionally include a plasticizer, a butene-rich copolymer, and an antioxidant. The hot melt adhesive is especially useful for bonding substrates which swell or elongate significantly in use. Such uses include adhering superabsorbent polymers to a substrate or adhering together two substrates, at least one of which has superabsorbent polymers, such as the layers of an absorbent core of a disposable hygiene article, such as a diaper. The composition, which does not contain a tackifier, demonstrates suitable elongation at break, stress retention, and thermal stability, making it well-suited for stabilizing expanded species such as superabsorbent polymers.

A sanitary fluid capture system allows for better fluid transfer to an absorbent pad. The system places moisture capturing and transferring materials in contact with the source of the fluids. Absorbent material forms a basin to capture excess fluid flow while it is sequestered by the absorbent materials.

In an absorbent article a three-dimensional opening hole mesh sheet, having a face which faces skin of a wearer of the absorbent article and a reverse or opposite side face within the absorbent article, is combined with an absorber which includes an air-laid pulp non-woven fabric. The mesh sheet has an array of mechanically embossed concave portions forming protrusions on the skin-facing face of the mesh sheet and recesses on the reverse or opposite face, i.e., the unexposed face inside the absorbent article.

Disclosed is a moisture-retaining body having a water-absorbing surface, having a structure in which, from a water-absorbing surface side, a water-permeable layer having water disintegrability and water permeability, a moisture-retaining layer having water disintegrability, water absorbability, and water retainability, a water-repellent layer including a water-soluble film and dots of a dot-like water-repellent resin with a diameter of 5 ?m to 150 ?m dispersed on a surface side of the water-soluble film facing the moisture-retaining layer, and a support layer having water disintegrability are sequentially laminated, as a moisture-retaining body which is quickly dissolved or decomposed by coming into contact with a large amount of water when dumped in a flush toilet or the like while being prevented from being dissolved or decomposed by retained moisture.

A disposable diaper whose absorber body changes its shape to motion of the wearer for enhanced fitting and wearing comfort, without excessively increased rigidity, includes an absorbent element having an absorber body and a wrapping sheet, and provided on its body side round and oval compressed areas, respectively. The round areas includes first and second compressed areas arranged respectively at intervals in the width and front-back directions, the second areas shifted from the first areas by half the intervals in the width and frond-back directions, the oval areas includes first compressed areas arranged between adjacent first round areas and between adjacent second round areas, with its major axis being aligned to the width direction, and second compressed areas, each arranged between first and second round areas with its major axis being aligned to a line connecting the first and second round areas.

Porous sheet product and methods of making and using the same. In one embodiment, the porous sheet product may be made by a process that includes providing an extrusion mixture, the extrusion mixture including a polymeric binder, a swelling agent, a compatibilizing agent, and a superabsorbent polymer, the superabsorbent polymer being in particle form. The superabsorbent polymer may be wet-milled such that its particle size before and after milling is reduced by a ratio of at least 5:1. The extrusion mixture may be melt-extruded to form a sheet material in film form. At least a portion of the swelling and compatibilizing agents may be removed. The porous sheet product is preferably liquid permeable and may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier and disposable garments.

An absorbent core comprising: a front portion; a back portion; a middle portion positioned between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core being a multi-layer core comprising at least two distinct core layers, wherein a first core layer comprises a channel having a first shape and a second core layer comprises a further channel having a second shape and wherein the first and second core layers are disposed one on top of the other such that a third channel shape is formed along said core length and width, and wherein said first and second shapes are substantially the same and are different to said third shape.

An absorbent article which can have an improved body exudate intake capability. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent system positioned between the topsheet layer and the backsheet layer. The absorbent system can have at least a fluid intake layer and an absorbent core. The fluid intake layer and the absorbent core can together define an aligned channel in the absorbent system. The aligned channel can create a void space in the depth direction of the absorbent article wherein at least a portion of the topsheet layer can be maintained in a spaced apart relationship from the bottom of the aligned channel.

A formed film laminate includes two formed films. Each formed film includes a first side and a second side. The first side includes a plurality of elongated ridges extending from a first land area, a plurality of valleys defined by adjacent elongated ridges and the first land area, and a plurality of primary apertures located at bottoms of the valleys. The second side includes a plurality of apertured protuberances extending from a second land area. Each of the protuberances includes a continuous sidewall extending to a distal end that includes a secondary aperture substantially aligned with a primary aperture. The first and second formed films have a thickness greater than about 0.9 mm under a pressure of 0.071 psi. The first formed film and the second formed film are rotationally offset by an angle greater than 0? and less than or equal to 90?.
