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.

[ We claim:] [27.]27. An elongated absorbent garment, comprising:a backsheet layer;a substantially liquid-permeable inner liner layer;an absorbent layer between the backsheet and inner liner layers;a liquid control layer on an inner surface of the inner liner layer;a front waistband and a rear waistband at longitudinally spaced regions of the article;a perineal region of the absorbent garment configured to fit against a perineum of a user;a front target region of the liquid control layer, against which urine from a male user first impinges substantially tangentially when the article is worn by the user;a series of rows of slits through the liquid control layer, wherein the rows do not overlap in a longitudinal direction, and each row extends substantially perpendicular to a longitudinal axis of the garment, the slits within each row being substantially parallel to each other and disposed at an acute angle to a longitudinal axis of the garment, the slits in each row forming a plurality of aligned strips in the liquid control layer, wherein each row of slits and strips forms a row of side-by-side loops projecting away from the absorbent layer, and the loops are configured to be in a first compressed condition within the liquid control layer when the garment is stored in a stretched condition, and the loops assume an elevated position with substantially all the loops projecting away from the garment and toward the user when the garment is in an operative position on the user, wherein at least one of the rows of loops is located in the front target region of the garment;wherein the strips in a row are substantially perpendicular to strips in an immediately adjacent row, such that each pair of adjacent rows presents side faces of the loops that lie in alternating perpendicular planes to interfere with longitudinal flow of urine along the liquid control layer;a plurality of connections between the inner liner layer and liquid control layers that transfers first and second stretching forces from the inner liner layer to the liquid control layer to move the loops to the elevated position, wherein the first stretching force is directed substantially parallel to the longitudinal axis of the garment, and the second stretching force is directed substantially perpendicular to the longitudinal axis of the garment; andwherein the loops are present in a density of 3-6 loops per square inch of liquid control layer surface area, a width of each strip is at least 2 mm, adjacent loops in a row are spaced no greater than the width of each strip, a length of each strip is at least 10 mm, and the loops are placed such that 90% of all angles that urine could travel will contact a loop projecting away from the garment within 5 cm of linear travel on the liquid control layer.
