Multilayered textile material in apparel

Abstract

Described are multilayered breathable and waterproof materials having at least two nonwoven fiber layers, each fiber layer including a plurality of unidirectionally oriented fibers coated with a matrix material. The fibers in a first one of the at least two nonwoven fibers layers form an angle of approximately 90° with respect to the fibers in another one of the at least two nonwoven fiber layers. An outer layer is adhered to a side of one of the at least two nonwoven fiber layers. A polyurethane inner membrane is adhered to another side of the at least two nonwoven fiber layers, wherein at least the inner membrane is embossed.
