Flame retardant corrosive resistant conductive fabric article and method
First Claim
1. A flame retardant metalized fabric article comprising:
- a) a polymer fabric substrate having a reverse side and an obverse side;
b) a conductive metal layer on one side of the substrate; and
c) a flame-retardant coating intermediate the conductive metal layer and the polymeric fabric substrate.

Abstract
Disclosed is a conductive, flame-retardant polymeric fabric composed of a woven or non-woven nylon, polyester or acrylic fabric. A surface of the fabric is provided with a flame-retardant layer applied by coating the flame-retardant directly onto the fabric surface. Disposed on the flame-retardant layer is a conductive metal applied preferably by vapor deposition. The resulting article not only has a surface resistance of less than one ohm/sq, but also the article has an Underwriter Laboratories very thin material (VTM) vertical bum test rating of zero rendering the article suitable for use as an electromagnetic interference shielding fabric.

16. A conductive metalized flame-retardant fabric article comprising:
-
a) a woven or non-woven polymeric fabric;
b) a flame-retardant coating applied directly to a surface of said fabric, said coating comprising a flame-retardant material uniformly disposed in a film forming polymeric liquid wherein said liquid is applied directly to one surface of said fabric and is dried, cured or polymerized in situ to form a coating about one mil thick on said fabric surface;
c) a vapor deposited conductive metal coating applied to said flame-retardant coating; and
d) said article having an Underwriter Laboratories very thin material (VTM) vertical burn test rating of zero and a surface resistance of less than one ohm/sq.
