Abstract
A disposable absorbent article, such as a diaper, is disclosed. The topsheet of the diaper is elastically extensible and provides a relatively low contact pressure against the skin of the wearer at relatively high elongations. This arrangement provides a diaper topsheet which can be elongated to conform to the shape of the wearer without causing undue discomfort or irritation. The relatively low ultimate contact pressure at relatively high elongation may be accomplished either through a low contact force differential material, or through a material which exhibits stress relaxation over a relatively short period of time. The topsheet may be a laminate having one elastomeric lamina and an inelastic lamina. Also disclosed is a method for making such a laminate.
