Abstract
A disposable absorbent garment has barrier elements on its inner liner to form barriers to flow of urine across the liner surface. In one embodiment, the barrier elements are loops formed by rows of slits through the liner material, such that the slits form rows of strips. Central portions of the strips are forced out of the plane of the liner to form wide based loops or humps on the inner surface of the garment when the garment is in place about the body of a wearer. These elevated loops form rows of raised obstructions that act as urine flow interference barriers. In other embodiments, the loops are preformed on the surface of the liner layer, or are formed from interdigitating strips. The loops are preferably provided in a target area of the garment where urine impinges the liner surface. Garments intended to be worn by males may have the loops distributed primarily throughout a front crotch region, to interfere with the substantially tangential movement of urine across the liner layer. The garment diminishes leakage of urine out of the waistband of the garment, and inhibits migration of liquid waste within the diaper. Apertures formed under the loops provide an opening through which liquid waste enters the interior of the garment.
