Zusammenfassung:	A multi-layer diaper includes a porous facing layer to be positioned adjacent an infant's skin, and absorbent batt, and a water-impervious backing sheet. The facing layer is provided with areas of preferential liquid flow, surrounded by areas of increased water repellency relative to the areas of preferential liquid flow. The areas of preferential liquid flow are in the form of thinned areas, areas of increased wettability or areas of normal wettability surrounded by water repellent borders. The flow paths are spread over at least the central portion of the facing layer to direct liquid to the absorbent batt.
