Abstract:
An absorbent article (20) comprising a wearer-facing topsheet (24), a backsheet (26) and an absorbent core (28) disposed between the topsheet and the backsheet, characterized in that the absorbent core comprises: a first absorbent layer (1) comprising a first substrate (2), a layer (3) of first superabsorbent polymer particles deposited on the first substrate, and a fibrous layer (4) of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles; a second absorbent layer (5), the second absorbent layer comprising a second substrate (6) and a mixed layer (7) deposited on the second substrate, the mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers, the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer (4) of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer (7) of the second absorbent layer (5), and wherein the first absorbent layer (1) is placed closer to the topsheet than the second layer (5).
Abstract:
The invention relates to absorbent cores having high amounts of superabsorbent polymer material which are immobilized by adhesive. The absorbent cores have reduced peak force when subjected to the Laminate Compression Extension Test Method and also exhibit reduced delamination upon swelling of the superabsorbent polymer material.
Abstract:
An absorbent core for disposable absorbent articles comprising absorbent material having a basis weight that varies across the absorbent core is provided.
Abstract:
An absorbent core (28) for use in an absorbent article, the absorbent core comprising: a first absorbent layer (1) comprising a first substrate (2), a layer (3) of first superabsorbent polymer particles deposited on the first substrate on a deposition area (8) and a fibrous layer (4) of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles, a second absorbent layer (5) comprising a second substrate (6) and a mixed layer (7) 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.

Abstract:
The present invention refers to a process of making a fibrous structure, wherein roughly graded material is provided to rotating, apertured drums. The drums have at least one needle roll in their inside. The roughly graded material is agitated inside the drums, whereby fibers or small fiber clusters are separated from each other. These fibers and small fiber clusters are flung through the apertures to the outside of the drum, where they are directed onto a foraminous carrier to form a fibrous structure. The fibrous structures are especially useful in absorbent articles.
