Estimating the term…
The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.
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;
