Claim:
A method of manufacturing a breathable absorbent article, the method comprising: A. locating an absorbent body on a backing layer, the absorbent body including at least one layer and having a first and a second surface, the backing layer disposed on the second surface and formed of a liquid impermeable material; B. locating a liquid permeable surface layer on the first surface of the perforated absorbent body, the absorbent body lying between the liquid permeable surface layer and the perforated backing layer; C. subsequent to step B perforating the backing layer and at least part of the absorbent body so that the backing layer and the at least part of the absorbent body are provided with empty cavities, wherein the backing layer enters the part of each cavity disposed in the absorbent body to form at least a portion of a wall of the cavity, the cavities being substantially cone-shaped and extending in a tapering manner from the backing layer towards the first surface of the absorbent body, wherein the smallest cross section of each cavity is located closer to the liquid permeable surface layer than is the largest cross section of the cavity to facilitate the entry of drying air into the cavities; and joining the liquid permeable surface layer and the backing layer.
