Abstract
Abstract A foam-laminated glass fabric is produced by forming a layer of foam vinyl chloride polymer on one side of a glass fabric, the layer being in the form of foam latex containing plasticizer for the polymer comprising flame retardant phosphate ester and polyethylene glycol bis 2-ethyl-hexoate. The latex is dried to below its normal equilibrium water content, and then the laminate is compressed and heated briefly to set the foam in its compressed configuration. The fabric is useful in the manufacture of drapery.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
17 words
A process as set forth in claim 1 in which said phosphate ester is a tri-cresyl phosphate.
Claim 2
Dependent Claim
16 words
A process as set forth in claim 1 in which said latex also contains a filler.
Claim 3
Dependent Claim
15 words
A process as set forth in claim 3 in which said filler comprises titanium dioxide.
Claim 4
Dependent Claim
20 words
A process as set forth in claim 1 in which said latex is dried below the normal equilibrium moisture content.
Claim 5
Dependent Claim
33 words
A process as set forth in claim 1 in which the heating of the compressed fabric raises the temperature of the foam layer above the second order transition temperature and the polymer flows.
Claim 6
Dependent Claim
81 words
A process for manufacturing a foam-laminated fabric useful for draperies, slipcovers, upholsteries, tablecloths, wallcovering and the like, comprising: forming on one side of a glass fabric a layer of foamed latex containing vinyl chloride polymer, plasticizers for said polymer including a flame retardant phosphate ester, and a filler for said polymer comprising titanium dioxide and antimony oxide, drying said fabric and said latex, compressing the resulting laminate, and heating the compressed fabric briefly to set the foam in its compressed configuration.
