An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed that provides an improved immobilization of absorbent polymer material when the article is fully or partially urine loaded. This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized when wet such that the absorbent core achieves a wet immobilization of more than 50%, preferably of more than 60%, 70%, 80% or 90% according to the Wet Immobilization Test described herein.

The present invention generally relates to absorbent sanitary articles for absorption of body fluids and in particular to a sanitary article of this type including a buffer composition adapted to adjust the natural pH of the absorbed body fluid to a pH that is compatible with the pH of skin.

An absorbent article, such as a sanitary napkin, a pantiliner or an incontinence pad, which improves diffusion property of a body fluid and maintains a stable absorption amount. In FIG. 3, a sanitary napkin (1) includes an absorber (4) including an upper layer sheet (10) disposed at a skin side, a lower layer sheet (11) disposed at a non-skin side, and a highly water-absorbing polymer (12) disposed between the upper layer sheet (10) and the lower layer sheet (11). The upper layer sheet (10) is provided with a plurality of protruding portions (14) bulging out to the skin side and forming space portions (13) to be filled with the highly water-absorbing polymer (12), and a joined portion (15) in which the upper layer sheet (10) and the lower layer sheet (11) are joined to each other intermittently on the peripheral edges of the protruding portions (14) along the circumferential directions.

Disposable absorbent articles suitable for providing leakage protection for users that experience relatively small to relatively large discharges of fluids are described. The article includes a primary topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. The absorbent system includes a first absorbent core and a second absorbent core, and wherein the primary topsheet and at least the first absorbent core include a plurality of recessed areas.

The present invention can provide a sanitary absorbent article which includes a Lactobacillus formulation inside an absorbent pad to absorb bodily secretions and effectively remove odor thereof without leakage of the Lactobacillus to the outside of the absorbent pad.

A material for distributing fluid can include a first side edge, a second side edge, a first end edge, and a second end edge. The material can include a first surface and a second surface opposite from the first surface. The material can be liquid impermeable and at least one of the first surface and the second surface include at least one channel. The channel can include a channel width, a channel length, and a channel depth. The channel width can be from 0.1 mm to 2.5 mm. The channel depth can be configured such that the channel does not extend completely through the material.

An absorbent structure is disclosed. The absorbent structure includes a first fibrous layer having a first surface and a second surface and a second layer having a first surface and second surface. The first fibrous layer is substantially planar and the second absorbent layer includes voids within the layer. The absorbent structure first fibrous layer and the second layer exhibit a structural integrity substantially equal to an absorbent structure without voids.
