Abstract:
Breathable absorbent article comprising a topsheet, a breathable backsheet and an absorbent core between said topsheet and said backsheet, said backsheet comprising an inner layer and an outer layer, said inner layer being closer to said absorbent core than said outer layer, said article being characterised in that said outer layer comprises a hydrophobic, gas-permeable fibrous fabric layer composed of polymeric fibres and said inner layer comprises a hydrophobic, gas-permeable apertured polymeric film, said apertured film having a first liquid transport direction and a second liquid transport direction opposite said first liquid transport direction, said inner layer being oriented such that said first direction is from said outer layer towards said absorbent core, said apertured film allowing a liquid transport in said first liquid transport direction which is larger than the liquid transport in said second liquid transport direction under an identical pressure drop across said apertured film.
