摘要:
A topsheet for a disposable absorbent article that includes a first hydrophobic plastic film layer, a second hydrophobic plastic film layer and hydrophobic thermoplastic synthetic fibrous layer disposed between the two layers. The first hydrophobic plastic film layer includes a plurality of first plane regions spaced apart from one another that extend parallel to one another in one direction and the second hydrophobic plastic first layer includes a plurality of second plane regions spaced apart from one another that extend parallel to one another in the one direction. Of the first and second plane regions, at least the first plane regions are formed with bridge regions and first rising regions.
