Abstract:
1. An absorbent article for improved feces isolation and immobilization comprising a topsheet, a backsheet, an absorbent core positioned between the topsheet and the backsheet, and a sublayer positioned between the absorbent core and the topsheet and in contact with the topsheet, a) said topsheet comprising a liquid impermeable material and including an outermost body-faceable and body-contactable surface of the absorbent article and at least one topsheet region with a multitude of apertures configured to pass at least some feces, whereby b) said sublayer comprising at least one acquisition layer and having a topsheet-facing surface and at least one sublayer region with a multitude of holes, whereby wherein said average greatest dimension of the apertures is less than said average smallest dimension of the holes, and wherein at least one topsheet region is positioned above at least one sublayer region to form at least one overlap zone, the overlap zone having a surface area of at least 6 cm 2 and an overlap open area when measured according to the test method for determining open area, the apertures of the topsheet being positioned above, or partially above, holes of the sublayer in the overlap zone to form combined apertures, a cross-section of the combined apertures having a combined aperture surface area in a plane of the body-facing surface of the topsheet, the overlap open area being less than the topsheet open area and from 15% to 50% of the overlap zone surface area.
