Non-occluding, liquid-impervious, composite backsheet for absorptive devices

摘要: A backing for an absorptive device such as a disposable diaper or sanitary napkin, said comprising combination of two layers. The first layer which does not contact the wearer's skin is preferably comprised liquid-impervious polymeric film like. second also has been made pervious to liquid by providing multiplicity relatively small protuberances, each ending in aperture, substantially across its entire surface. apertured resemble tiny volcano cross-section, exhibit soft, highly consumer preferred tactile impression sometimes characterized "silky".In backsheets present invention, oriented so that volcano-like cusps constitute exposed portion backsheet. This minimizes area between backsheet and skin. In particularly embodiment macroscopically expanded provide three-dimensional pattern surface, thereby increasing amount stand-off impermeable composite apertures prevent occlusion circulation air impervious effect enhanced even further when enhance layer. reduced reduce tendency toward perspiration sticking
