Abstract
The present invention relates to a unitary absorbent structure and method thereof wherein said unitary absorbent structure comprises an absorbent core (5) and/or an acquisition (2) and dispersion (3) layer, said absorbent core (5) and/or an acquisition (2) and dispersion (3) layer comprising at least one non-woven fibrous substrate layer (23) having a void volume suitable to be penetrated by super absorbent particles, characterized in that said super absorbent particles are dispersed in the substrate layer (23) according to a size distribution gradient along the depth direction or z-direction of said absorbent core (5) and/or acquisition (2) and dispersion (3) layers.
Claims26
A unitary absorbent structure comprising an absorbent core and/or an acquisition and dispersion layer, said absorbent core and/or an acquisition and dispersion layer comprising at least one non-woven fibrous substrate layer having a void volume penetrated by super absorbent particles, wherein said super absorbent particles are dispersed in the substrate layer according to their particle size distribution gradient along the depth direction or z-direction of said absorbent core and/or acquisition and dispersion layers.
(canceled)
Absorbent article comprising:
- a unitary absorbent structure;
- a liquid pervious topsheet;
- a liquid impervious backsheet;
- wherein the
- absorbent structure is positioned between the liquid pervious topsheet and the liquid impervious backsheet, and wherein the unitary absorbent structure comprising an absorbent core and/or an acquisition and dispersion layer, said absorbent core and/or an acquisition and dispersion layer comprising at least one non-woven fibrous substrate layer having a void volume penetrated by super absorbent particles, wherein said super absorbent particles are dispersed in the substrate layer according to their particle size distribution gradient along the depth direction or z-direction of said absorbent core and/or acquisition and dispersion layers.
