ABSTRACT:
A method of manufacturing a three-dimensional fabric of the type which may be used in absorbent garments, dressings or the like involves the use of an apertured collector element which has a predetermined three-dimensional shape. The method involves positioning material adjacent to one side of the apertured collector element and developing a pressure differential between the one side of the apertured collector element and a second, opposite side to force the fabric material against the apertured collector element. The material, which has conformed to the shape of the collector element, is then solidified into its intended three-dimensional shape.
