| 摘要 |
The present invention provides a multi-layered, lightweight "barrier" substrate with two (optionally anti-microbial and waterproof) fabrics or layers laminated together with a film providing both adhesion and a barrier. Various processes may make water repellant textile fabrics. The term "Barrier Substrate" as used herein means essentially impermeable to water, i.e. can support a considerable column of water without water penetration through the fabric. Such behavior is sometimes termed "water resistant."The second layer providing the barrier can be either urethane (preferred), polyester or an acrylic material which can be a breathable, or non-breathable film which may be back coated after lamination or extrusion creating a third layer. Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present invention can be implemented in a variety of forms. Therefore, while this invention has been described in connection with particular examples thereof, the true scope of the invention should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the specification and claims.
