Abstract
An absorbent article has an absorbent core and a liquid permeable top sheet made of polyolefin material. An acquisition layer is provided between the top sheet and the core. The acquisition layer is a nonwoven fabric made from polyolefin fibers bonded by a cured resin. The acquisition layer has a larger pore size than the top sheet and is treated with a surface active agent to render it hydrophilic.
