Abstract
Abstract An insulating, multilayer quilted wallpaper web comprising a non-woven facing sheet having fire-retardant properties, a face side provided with a decorative pattern and a back side, an intermediate insulating layer substantially coextensive with the facing sheet and having one side contiguous to the back side of the facing sheet, and a non-woven backing sheet substantially coextensive with the insulating layer and contiguous to the other side of the insulating layer. The facing sheet and the backing sheet are relatively thinner than the insulating layer and are intermittently secured to the insulating layer to form a quilted unitary web.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
An insulating, quilted multilayer wallpaper web which comprises a fire-retardant facing sheet which is a non-woven fabric web containing inherently fire-retardant fibers which do not sustain combustion but which give off a flame-dousing gas when ignited, an intermediate synthetic resin foam insulating layer of microporous structure substantially coextensive with said facing sheet and having one side contiguous to the back side of said facing sheet; and a backing sheet substantially coextensive with said insulating layer and contiguous to the other side of said insulating layer; said facing sheet and said backing sheet being relatively thinner than said insulating layer and being secured to said insulating layer by intermittent bonding to form a quilted unitary web.
Claim 2
Dependent Claim
115 words
An insulating, quilted multilayer wallpaper web which comprises a fire-retardant facing sheet which is a non-woven fabric web containing inherently fire-retardant fibers which do not sustain combustion but which give off a flame-dousing gas when ignited, an intermediate synthetic resin foam insulating layer of microporous structure substantially coextensive with said facing sheet and having one side contiguous to the back side of said facing sheet; and a backing sheet substantially coextensive with said insulating layer and contiguous to the other side of said insulating layer; said facing sheet and said backing sheet being relatively thinner than said insulating layer and being secured to said insulating layer by intermittent bonding to form a quilted unitary web.
Claim 3
Dependent Claim
35 words
The quilted insulating wallpaper in accordance with claim 1, wherein the insulating layer is a polypropylene microfoam and wherein said facing sheet and said backing sheet are intermittently bonded to said insulating layer by stitching.
Claim 4
Dependent Claim
80 words
The quilted insulating wallpaper in accordance with claim 1 wherein said non-woven fabric web contains about 75 to about 900 percent by weight polyester fiber and about 25 to about 10 percent by weight biconstituted fiber bound with a binder comprising a copolymer of vinylidene chloride and an acrylic ester, and wherein said biconstituted fiber contains about 50 percent by weight of a vinyl chloride and vinyl acetate copolymer fiber and about 50 percent by weight of a vinal fiber.
Claim 5
Dependent Claim
74 words
The quilted insulating wallpaper in accordance with claim 1 wherein said non-woven fabric web contains about 83 percent by weight polyester fiber and about 17 percent by weight biconstituted fiber bound with a binder comprising a copolymer of vinylidene chloride and an acrylic ester, and wherein said biconstituted fiber contains about 50 percent by weight of a vinyl chloride and vinyl acetate copolymer fiber and about 50 percent by weight of a vinal fiber.
Claim 6
Dependent Claim
39 words
The quilted insulating wallpaper in accordance with claim 1 wherein fire-retardant fibers which do not sustain combustion but which give off a flame-dousing gas when ignited are distributed between said facing sheet and said insulating layer secured in place.
Claim 7
Dependent Claim
62 words
The quilted insulating wallpaper in accordance with claim 5 wherein said fire-retardant fibers are biconstituted fibers and polyester fibers bound with a binder comprising a copolymer of vinylidene and an acrylic ester, and wherein said biconstituted fibers contain about 50 percent by weight of a vinyl chloride and vinyl acetate copolymer fiber and about 50 percent by weight of a vinal fiber.
Claim 8
Dependent Claim
41 words
The quilted insulating wallpaper in accordance with claim 5 wherein said fire-retardant fibers are biconstituted fibers containing about 50 percent by weight of a vinyl chloride and vinyl acetate copolymer fiber and about 50 percent by weight of a vinal fiber.
