| 摘要 |
The present invention relates to a textured, microapertured web formed from a formed film ply which is suitable for use as a topsheet in an absorbent article. One embodiment of the present invention is a fluid permeable web comprised of a polymeric formed film ply having at least two layers, each of the layers having opposed first and second exterior surfaces. The polymeric formed film ply is provided with microapertures placing the first exterior surface and the second exterior surface in fluid communication with one another and the exterior surfaces are comprised of materials that provide a surface energy gradient between the surfaces. One preferred embodiment of the present invention is a multi-layer formed film ply having a first layer, a second layer, where one of the first or second layers is a block copolymer of a polyether and another polymer and the other layer is a hydrophobic layer as defined herein. Methods of producing such webs are also disclosed. |
