A delamination problem in fabric laminates made of a fabric laminated to a nonporous, hydrophilic organic polymer film, such as a breathable polyurethane film, was found to be caused by the hydrophilic nature of the polymer. A particular adhesive pattern was devised to overcome the delamination problem. More specifically, a wash-durable fabric laminate of a continuous, non-porous hydrophilic polymer, e.g., a breathable polyurethane, layer and a fabric layer were bonded together by a discontinuous, but interconnected pattern of an adhesive layer. The fabric laminate is water-vapor-permeable, air-impermeable and liquid water impermeable. |
