Abstract
The present invention describes a novel absorbent core for the absorbent article in which the top surface of the core is embossed in a pattern that is made from curves rather than straight lines or polygons. In a preferred embodiment, the top surface is embossed with a pattern made by circles with spacing between consecutive circles. The novel article is not only less rigid and smoother on the body surface, but also exhibits better absorptive capacity. Various other embodiments are described and are within the scope of the invention.
