Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
83 words
A fabric for protective clothing, containers and covers for protection against hazardous liquids and vapors consisting of an inner layer of an abrasion resistant, high modulus fabric and a film layer bonded on at least one surface of said high modulus fabric, said film layer being adhesively bonded, comprising a fusible meltable polyhalogenated ethylene resin selected from the group consisting of ##STR2## said resin having a melting point between about 175° to 350° C. whereby said fabric prevents the passage of hazardous vapors.
Claim 2
Dependent Claim
83 words
A fabric for protective clothing, containers and covers for protection against hazardous liquids and vapors consisting of an inner layer of an abrasion resistant, high modulus fabric and a film layer bonded on at least one surface of said high modulus fabric, said film layer being adhesively bonded, comprising a fusible meltable polyhalogenated ethylene resin selected from the group consisting of ##STR2## said resin having a melting point between about 175° to 350° C. whereby said fabric prevents the passage of hazardous vapors.
Claim 3
Dependent Claim
20 words
