An absorbent article (20) having an absorbent core comprising at least about 80% of superabsorbent polymers (SAP) by weight of its absorbent material. An acquisition-distribution system (ADS) (50) is at least partially disposed between the absorbent core and the topsheet. The ADS extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front edge to a point A2 disposed at a distance D from the back edge of the article, D being equal to 32% of the length L of the article. The ADS has a basis weight which may be at least 20% lower at the point A2 than at the point A1.

Absorbent structures and methods of manufacture are disclosed. In one embodiment, a method of manufacturing may comprise, directing a stream of particles toward a layer, spraying the stream with a first adhesive, the first adhesive contacting the stream at a first contact point, spraying the stream with a second adhesive, the second adhesive contacting the stream at a second contact point, the first contact point being different from the second contact point, depositing the intermixed particles, first adhesive, and second adhesive onto the layer, and covering the mixture of the particles, the first adhesive, and the second adhesive with a second layer.

An absorbent article (1) comprising a top sheet (2), a back sheet (3), an absorbent body (4) disposed therebetween and a second sheet (10) disposed between the top sheet (2) and the absorbent body (4), wherein the second sheet (10) is composed of a laminate having a nonwoven fabric layer (11) and a plastic film layer (12) from the top sheet side and has a plurality of through-holes (13).

The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing and positioning particulate materials in a desired pattern onto a moving carrier layer. The method allows accurate forming of a pattern of particulate material clusters at high production speed having improved attachment properties, with reduced raw material usage and relative low cost. The present invention foresees in the need for improved thin, flexible, lightweight absorbent structure having optimal absorption, distribution and retention.

Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary absorbent core may comprise a carrier sheet having a first edge region, a central region, and a second edge region and particulate material disposed on the carrier sheet through the first edge region, the central region, and the second edge region. The absorbent core may additionally have an absorbent core width and the central region may have a central region width, and the central width may comprise between 33% and 75% of the absorbent core width. Further, the central region may comprise an average basis weight of particulate material that is at least 110% of an average basis weight of particulate material within at least one of the left edge region and the right edge region.

A disposable absorbent article for wearing about the lower torso of a wearer is provided. The disposable absorbent article has a chassis including: a topsheet; a backsheet containing a polymeric film; and an absorbent core disposed between the topsheet and the backsheet. The polymeric film is at least 20 mm more narrow than the chassis. The disposable absorbent article has an opacity strengthening patch disposed on the backsheet, wherein the opacity strengthening patch is connected to one of the group consisting of the leg gasketing system, the polymeric film layer, and the backsheet by an adhesive. The adhesive includes: an amorphous polyolefin composition and a heterophase polyolefin composition having an amorphous character and crystalline blocks. The adhesive is substantially tackifier-free.

An embodiment of the undergarment can include an undergarment liner comprising a top layer; a bottom layer; an absorption layer; and a garment adhesive layer. The top layer can be oriented as the upper most layer and is the layer that comes in contact with the wearer of the liner. The absorption layer is oriented between the top layer and the bottom layer. The garment adhesive layer can comprise a coupling surface and an adhesion surface. The coupling surface opposes adhesion surface. The undergarment liner also comprises a first perforation line that extends through each layer and subdivides the undergarment liner into a plurality of subsections.

A feminine hygiene pad having a topsheet including a fibrous nonwoven web material having hydrophilic fibers, and an absorbent layer including an open-celled foam formed through polymerization of a high internal phase emulsion (HIPE) is disclosed. The topsheet and the absorbent layer are disposed in direct face-to-face relationship with each other, and attached to each other within a bonding region. Within the bonding region, each first identifiable point of attachment between the topsheet and the absorbent layer has a neighboring second identifiable point of attachment between the topsheet and the absorbent layer within a 6 mm radius of the first identifiable point of attachment.
