Abstract:
1. A fabric substrate comprised of at least 20% cotton fiber by weight of the total weight of said substrate, wherein said substrate has a first surface and a second surface, wherein at least one of said first surface and said second surface has been coated with a hydrophilic fluorine-containing stain release agent, a hydrophobic fluorine-containing stain repellent agent and a hydrophobic cross-linking agent selected from the group consisting of monomers with blocked isocyanates, aromatic diisocyanates, blocked diisocyanates, blocked isocyanate-containing polymers, diisocyanate-containing monomers, and diisocyanate-containing polymers; and wherein said substrate exhibits a change in surface energy in response to a change in the substrate's environment to the extent that upon exposure to a temperature of 25 degrees C. the measured surface energy is from less than about 20 millijoules per square meter, and upon exposure to a temperature of 40 degrees C., the measured surface energy is greater than about 20 millijoules per square meter.
