Abstract
Absorbent articles with carefully controlled stretch properties are disclosed. In particular, the articles exhibit stretch not only in the lateral direction but also in the longitudinal direction. Specifically, the articles have a biaxial stretch ratio, which refers to a ratio of stretch along the hip circumference of the article to the amount of stretch in the longitudinal direction, that is from about 1.0 to about 2.5, and particularly from about 1.1 to about 1.5. Absorbent articles made in accordance with the present invention are capable of accommodating a relatively large size range of wearers. The articles also exhibit improved fit and prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.
