Abstract
The invention provides a fabric for use in the manufacture of protective garments, containers and covers comprising an inner layer of an tear resistant fabric of high tensile fibers, a film layer bonded on the top surface of said tear resistant fabric comprising a meltable polyhalogenated resin and a film layer of an ethylene-vinyl alcohol copolymer bonded on the bottom surface of the tear resistant fabric.
Claims14
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.
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.
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.
