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/m.sup.2)
at a temperature of about 25 degrees C. and a surface energy greater than
about 20 mJ/m.sup.2 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.
