A disposable absorbent article having a breathable fluid impervious backsheet. The disposable absorbent article preferably includes a fluid pervious topsheet, a breathable, fluid impervious backsheet secured to the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The breathable, fluid impervious backsheet exhibits substantially zero dynamic fluid transmission when subjected to an impact energy of about 1000 joules/m2, and exhibits a mass vapor transmission rate of at least about 2000 g/m2/24 hr.
L'invention a trait à un article absorbant jetable, pourvu d'une couche inférieure respirant mais imperméable aux fluides, lequel article absorbant jetable comporte, de préférence, une couche supérieure perméable aux fluides, une couche inférieure, respirant mais imperméable aux fluides, rattachée à la couche supérieure et une âme absorbante placée entre les couches supérieure et inférieure. La couche inférieure, respirant mais imperméable aux fluides, qui fait montre de propriétés de transfert dynamique de fluides quasiment nulles lorsqu'elle est soumise à une énergie de rupture d'une valeur d'environ 1000 joules/m?2¿, est dotée d'un régime de transfert de masse de la vapeur d'eau d'au moins 2000 g/m?2¿/24 heures environ.
