  • Patent number: 5622762
    Abstract: A multi-layer material suitable for production of divers' suits, such material eliminating the conventional waterproof material characteristic of the prior art. In one form, the multi-layer material comprises an outer layer of Lycra bonded to a first inner layer of a plush-type material which is then bonded to a second inner layer of a denser plush-type material. The bond between the Lycra and first inner plush layer is preferably formed by coating the facing surfaces with a solid film of a water resistant contact cement which resists any transfer of water between the Lycra and first inner plush layer. The first inner plush layer is then bonded to the second inner plush layer by either an adhesive or other fastening means which allows water transfer between the first and second plush-type material layers.
