Abstract
Abstract The durable and reusable incontinent underpads of the invention are 4-layer fabrics, incorporating a first layer of woven or knit fabric, a second layer of non-woven felt, a third layer of polyurethane film, and a fourth layer of woven or knit fabric. The first and second layers are quilted together--as by stitching, or otherwise--to form a fluid absorbing portion for the underpad. The third and fourth layers are laminated together with a urethane adhesive to form a leakage preventing portion for the pad. The second and third layers are also laminated together with the urethene adhesive to complete the underpad constructions.
