Abstract

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.
