The present invention relates to breathable absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners. According to the present invention the articles are provided with an apertured backsheet for breathability. At least one of the breathable layers of the backsheet comprises a resilient, three dimensional web which consists of a liquid impervious polymeric film having apertures. The apertures form capillaries which are designed such that the backsheet provides an increased barrier to liquid passage out of the article and maintains water vapour permeability when the web is exposed to compressive pressure.
L'invention concerne des articles absorbants imper-respirants tels que couches pour bébés, garnitures pour adultes incontinents, et surtout serviettes hygiéniques ou protège-slips. Selon l'invention, les articles comportent une feuille support perforée qui leur confère un caractère imper-respirant. Au moins l'une des couches imper-respirantes de la feuille support comprend une nappe tridimensionnelle élastique, constituée d'un film polymère imperméable aux liquides et présentant des orifices. Ces derniers forment des capillaires qui sont conçus de sorte que la feuille support constitue une barrière renforcée contre le passage du liquide à l'extérieur de l'article et qu'elle conserve son caractère imperméable à la vapeur d'eau lorsque la nappe est soumise à une compression.
