Abstract

Absorbent article allowing for convective gas/air transport therethrough, especially by providing absorbent cores, which have sufficient basis capacity and air/gas permeability at the same time. The absorbent core comprises a liquid storage region, and a liquid acquisition/distribution region positioned between the liquid storage region and the topsheets said acquisition/distribution region comprises an evaporation barrier layer/region.
