There is provided a feminine hygiene pad comprising a cover adjacent a capillarity fabric having regions of high and low capillarity, which is adjacent a retention layer. In a preferred embodiment, a creped spunbond layer is used as the cover material and a co-apertured intake/distribution layer and transfer delay layer are the capillarity fabric. Combining these improvements into an integrated absorbent system allows the successful achievement of variable flow management and a successful balance between intake and cover desorption properties. The result is improved multiple intake performance and a clean and dry cover surface during use.

L'invention concerne une protection hygiénique féminine comprenant un revêtement jouxtant un tissu à capillarité doté de zones de haute et faible capillarité, lequel jouxte une couche de rétention. Dans un mode de réalisation préféré, on utilise une couche filée-liée crêpée comme matériau de revêtement et, comme tissu à capillarité, une couche d'absorption/de répartition co-perforée et une couche de retardement de passage. La combinaison de ces améliorations en système absorbant intégré permet d'obtenir une gestion réussie du flux variable et un meilleur équilibre entre les propriétés d'absorption et celles de désorption du revêtement. On obtient ainsi une absorption multiple améliorée et une surface de revêtement sèche et propre durant l'emploi.
