Abstract
The invention is a stretchable layered fabric laminate which is air impermeable and waterproof while being permeable to water vapor. The stretchable fabric laminate includes a stretchable composite material layer consisting of a hydrophobic protective layer of a porous polymeric material on each side of a layer of hydrophilic water-vapor-permeable synthetic polymer. The composite material layer is laminated to at least one layer of stretchable fabric. The stretchable layered fabric laminate has excellent stretch and recovery properties in both machine and transverse directions, and is useful for the manufacture of form-fitting articles of protective clothing and other end uses.
