Abstract

A woven fabric substrate is treated with a fluorochemical stain resist agent and thereafter extrusion coated substantially on the back side with a layer of thermoplastic polymeric material so as to yield a final construction which exhibits both fluid and stain resistant properties. The fabric substrate can also be treated with an flame retardant agent, an antistatic agent, and/or an anti-microbial agent.

Claims

1. An article comprising:

a colored fabric substrate having a first side and a second side;

a liquid impermeable back coating on the second side of the substrate;

a low surface energy stain resist compound disposed on at least the first side of the substrate; and

a UV inhibitor disposed on at least the first side of the substrate.

2. An article comprising a colored textile, said article having:

a hydrostatic liquid resistance of 50 millibars or greater;

a spray resistance of 70 or greater;

a rain resistance of 2 grams or less; and

a Eof 4.0 or less when subjected to 225 kj.
