摘要： Disclosed is a feminine hygiene pad with an absorbent system including: an absorbent foam layer having a wearer-facing surface and an outward-facing surface, having a plurality of apertures providing z-direction passageways from the wearer-facing surface to the outward-facing surface; and a porous spacer layer beneath the foam layer and underlying a majority of openings of the apertures in an outward-facing surface of the foam layer. The spacer layer functions to provide structure, beneath the absorbent foam layer, that holds open a desired amount of unoccupied space between the absorbent layer and a backsheet of the pad, into which unabsorbed menstrual fluid may flow and temporarily reside, during the time required for the absorbent layer to effectively imbibe the fluid.

摘要： The present invention is directed to methods for deforming a web comprising the steps of supplying a first layer of a web; weakening the first layer at a plurality of locations to create a plurality of weakened, melt-stabilized locations in the first layer; supplying a second layer of the web onto at least part of the first layer; and forming a plurality of first features in the first layer and a plurality of second features throughout the first and second layers of the web in the z-direction, wherein the plurality of first and second features are formed simultaneously.
