Abstract
An absorbent article such as a diaper includes a backsheet layer, a substantially liquid-permeable liner layer, and an absorbent body located between the backsheet and the liner. The backsheet and liner layers generally define a front waistband section, a rear waistband section, and an intermediate section, with the intermediate section interconnecting the front and rear waistband sections. The liner includes a plurality of spaced apart longitudinal upstanding ridges located at least in the intermediate section to provide barriers to transverse migration of body exudates. The upstanding ridges are formed by providing a plurality of laterally spaced apart and alternating longitudinally adhered liner portions and unadhered liner portions. Elastic members are located subjacent the unadhered portions and include a front end, a rear end, and a central portion disposed between the front and rear ends.
