Abstract
Abstract Disposable absorbent articles such as a diaper or a sanitary napkin having a fastening system comprising a pressure-sensitive adhesive fastener having a textured fastening surface. The pressure-sensitive adhesive fastener comprises a backing web having bulbous surface aberrations projecting from a surface of the web and a layer of pressure-sensitive adhesive coated over and bonded to at least a portion of the surface of the bulbous surface aberrations of the backing web. When the fastening system of the present invention is affixed to a diaper, the overlapping portions of the diaper are maintained in contact with each other while the fastening system prevents separation of the overlapping waist portions because it is able to resist the wearer-generated peel forces encountered during wear and the shear stress encountered when the diaper is worn. Further, the fastening system allows the user to easily refasten and check the diaper for soiling and removing the diaper without rendering the fastening system unrefastenable or the diaper unusable.
