Abstract
Abstract The utilization of double knit fabrics is extended to fields other than their conventional employment in wearing apparel. This is accomplished by dimensionally stabilizing the otherwise easily distortable double knit material by applying to one surface thereof a controlled layer of a latex of a polymeric coating composition comprising a copolymer of ethylene and vinyl chloride in an aqueous vehicle. The thus coated material is properly cured and dried.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
67 words
The method of structurally stabilizing double knit fabric which comprises the step of applying to the back thereof a coating layer of a resin latex composition comprising a copolymer and ethylene and vinyl chloride having a pH of 8.5±0.5 and a Brookfield viscosity of about 15,000 as determined by RVF employing #5 spindle @ 20 RPM, and drying the coated fabric at a temperature below 400° F.
Claim 2
Independent Claim
67 words
The method of structurally stabilizing double knit fabric which comprises the step of applying to the back thereof a coating layer of a resin latex composition comprising a copolymer and ethylene and vinyl chloride having a pH of 8.5±0.5 and a Brookfield viscosity of about 15,000 as determined by RVF employing #5 spindle @ 20 RPM, and drying the coated fabric at a temperature below 400° F.
Claim 3
Dependent Claim
15 words
The method as defined in claim 1 wherein said latex comprises about 40-65% total solids.
Claim 4
Dependent Claim
14 words
The method as defined in claim 1 wherein said latex further comprises fire-retardant chemicals.
Claim 5
Dependent Claim
27 words
The method as defined in claim 3 wherein said fire retardant chemicals comprise one or more salts from the group consisting of alumina trihydrate and alkaryl phosphate.
Claim 6
Dependent Claim
27 words
The method as defined in claim 1 wherein said latex coating is applied in an amount constituting 2.9 to 3.6 ounces per square yard of the fabric.
Claim 7
Independent Claim
33 words
The method as defined in claims 1,2, or 5 wherein said drying is effected at a temperature in the range of 280° to 310° F. for a period of 1.5 to 2.0 minutes.
Claim 8
Independent Claim
59 words
The method as defined in claims 1 or 5 wherein said latex is applied by a pickup roll rotating in a reservoir of said latex composition, to a running length of said fabric; and said drying is effected during its moving through a heated environment while being maintained laterally extended to its full width in taut or tensioned condition.
Claim 9
Dependent Claim
34 words
A structurally stabilized double knit fabric suitable for use in wall covering application, said fabric containing on the backside thereof a dried and cured latex coating of a copolymer of ethylene and vinyl chloride.
Claim 10
Dependent Claim
34 words
A structurally stabilized double knit fabric suitable for use in wall covering application, said fabric containing on the backside thereof a dried and cured latex coating of a copolymer of ethylene and vinyl chloride.
Claim 11
Dependent Claim
17 words
A fabric as defined in claim 8 which further contains flame-retardant chemicals, rendering the same substantially fireproof.
Claim 12
Dependent Claim
24 words
A fabric as defined in claim 8 or 9 which contains 2.9 to 3.6 ounces of said dried coating per square yard of fabric.
Claim 13
Dependent Claim
33 words
A fabric as defined in claim 8 or 9 having a pressure sensitive adhesive layer applied to said latex coating, said adhesive comprising acrylic resin and being protected by a releasable peel-off backing.
