AbstractThe present invention provides a female component for engaging a complementary hook component in a refastenable fastening device. The female component of the present invention is capable of engaging a hook component that has flexible, resilient individual hook elements. The female component comprises at least two, and preferably three zones or layers. Each zone has certain of the desired individual characteristics for entangling and holding the hooks of the mating hook component. These include a first zone for admitting and engaging at least some of the hooks of the complementary hook component (the "entanglement" zone), a second zone for providing space for the hooks to occupy after they have been admitted by the entanglement zone (referred to as the "spacing" zone), and a backing adjacent to the spacing zone for providing a foundation for the entanglement and spacing zones. The present invention also provides a fastening device having a hook fastening component and a female component that comprises the multi-layer female component of the present invention. The present invention also relates to disposable articles and more particularly to a disposable diaper having such an improved fastening device.
