An absorbent article, including a liquid permeable top sheet, a pulpless absorbent core, the core including synthetic fibers and a super absorbent material, the super absorbent material being settled and stabilized by an open formation bottom high loft layer with fibers oriented in a Z direction, and a liquid impermeable backsheet, wherein the absorbent core is positioned between the top sheet and the backsheet.

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.

An absorbent core for use in an absorbent article, the absorbent core including a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate on a deposition area and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, and a second absorbent layer comprising a second substrate and a mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers deposited on the second substrate. The first and second absorbent layers are combined together such that at least a portion of the fibrous thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer.

A personal hygiene absorbent article is disclosed. The personal hygiene absorbent article includes an absorbent layer having a narrow portion between the front edge and the back edge of the absorbent layer, and a distribution layer having a narrow portion between the front edge and the back edge of the distribution layer.

A package comprising a plurality of absorbent articles such as diapers comprising a flexible package material. The articles are folded along a first fold line, which is substantially perpendicular to a central longitudinal axis and a second fold line extending transversely across a front and back waist regions along a second fold line, which is substantially perpendicular to the central longitudinal axis. The package may have a Package Out-of-Stack Compression Deflection Differential at 0.6 psi of at most 3.0 mm according to the Package Compression Test detailed herein. The second fold line may lie between the first fold line and a front waist edge of the absorbent core in the front waist region and/or lies between the first fold line and a back waist edge of the absorbent core in the back waist region.

Absorbent article (20) for personal hygiene such as diaper comprising an absorbent core (28) having two lateral absorbent zones (61, 63) disposed between respectively between a first and second longitudinally-extending channels (26a, 26b) and a first and second longitudinal edges (604, 606) of an absorbent layer (60). The lateral absorbent zones are profiled in the transversal direction, so that the basis weight of the absorbent material is higher towards the respective channel than towards the respective longitudinal side edge.
