Claims
- 1. A laminated fabric for protective clothing, containers and covers for protection against hazardous liquids and vapors consisting of a layer of an tear resistant fabric of high tensile fibers, an outer film layer bonded to said tear resistant fabric comprising a fusible or meltable polyhalogenated ethylene resin, and an inner film comprising an ethylene-vinyl alcohol copolymer layer bonded to said tear resistant fabric, whereby said laminated fabric prevents the passage of hazardous vapors.
- 2. The fabric for protective clothing according to claim 1 wherein said polyhalogenated resin comprises a fluorinated ethylene perfluoroalkyl vinyl ether copolymer resin.
- 3. The fabric for protecting clothing according to claim 1 wherein said polyhalogenated resin comprises a fluorinated ethylene propylene copolymer resin.
- 4. The fabric for protective clothing according to claim 3 wherein said polymer resin has a melting point between about 175 to 350.degree. C.
- 5. The fabric for protective clothing according to claim 1 wherein said high tensile fiber is selected from the group consisting of polyethylene terephthalate, poly p-phenylene terephthalamide, poly m-phenylene terephthalamide, carbonaceous polymeric oxidized polyacrylonitrile, nylon and polybenzimidazole.
- 6. The fabric according to claim 1 comprising a tear resistant fabric sandwiched between a film layer of a polyhalogenated resin film and a film layer of an ethylene-vinyl alcohol copolymer.
- 7. A fabric for protective clothing, containers and covers for protection against hazardous liquids and vapors consisting of a layer of an abrasion resistant fabric, a first film layer adhesively bonded on one surface of said abrasion resistant fabric, said first film layer comprising a fusible and/or meltable polyhalogenated ethylene resin selected from the group consisting of ##STR2## said resin having a melting point between about 175 to 350.degree. C., and a second film layer comprising an ethylene-vinyl alcohol copolymer layer bonded on the other surface of said fabric, whereby said fabric prevents the passage of hazardous vapors.
- 8. The fabric for protective clothing according to claim 7 wherein said abrasion resistant fabric comprises fibers selected from the group consisting of polyethylene terephthalate, poly p-phenylene terephthalamide, poly m-phenylene terephthalamide, nylon, carbonaceous polymer, polybenzamidazole, and oxidized polyacrylonitrile.
- 9. A fabric for protective clothing, containers and covers for protective clothing, containers and covers for protection against the penetration of hazardous liquids and vapors comprising a layer of an abrasion resistant fabric comprising high modulus fibers, a top film layer consisting of a polymer of the formula:
- [CF.sub.2 --CF--(O(CF.sub.2)CF.sub.3)--CF.sub.2 --CF.sub.2 ].sub.n
- adhesively bonded onto said fabric layer, said polymer having a melting point of about 100 to 350.degree. C., and a bottom film comprising a layer of an ethylene-vinyl alcohol copolymer which is bonded to the bottom of said fabric layer.
- 10. A protective garment fabricated in part from the fabric according to claim 1.
- 11. The garment of claim 10 including a face piece comprising an ethylene-vinyl alcohol copolymer.
- 12. A protective garment fabricated in part from the fabric according to claim 7.
- 13. A protective garment fabricated in part from the fabric according to claim 9.
- 14. The protective garment of claim 13 including a face piece comprising a layer of an ethylene-vinyl alcohol copolymer and a layer of an ionomer or nylon.
