<p>A water-vapor-permeable, water-resistant composite material comprises water-resistant, water-vapor-permeable functional layer having first side and second side; material attached to the first side of the functional layer; discrete polymer spots forming discontinuous, lining-producing pattern on the surface of the second side of the functional layer; and water-vapor-permeable cover layer that is joined to the polymer spots. An Independent claim is also included for a method of making water-vapor-permeable, water-resistant composite material comprising providing water-resistant, water-vapor-permeable functional layer, attaching material to first side of the functional layer, providing discrete polymer spots forming discontinuous, lining-producing pattern on the surface of the second side of the functional layer, and joining water-vapor-permeable cover layer to the polymer spots.</p> |
