Abstract:
1. A textile fabric comprising a textile fabric substrate having a smooth surface with one or more regions of a bi-component coating disposed upon and bonded thereto, said one or more regions of a bi-component coating comprising one or more regions of a first coating material and one or more regions of a second coating material, at least a portion of the first coating material directly contacting and overlying or underlying at least a portion of the second coating material, and, in response to changing temperature, said one or more regions of the first coating material exhibiting a first characteristic thermal expansion or contraction, the first coating material comprising a polymer, the polymer comprising urethane, and the first characteristic thermal expansion or contraction comprising expanding or contracting gradually over a temperature range, and said one or more regions of said second coating material exhibiting a second characteristic thermal expansion or contraction contrasting to said first characteristic thermal expansion or contraction, the second coating material comprising a soft rubbery polymer comprising polyurethanes, silicones, or acrylates and remaining soft over the temperature range, the first coating material and the second coating material exhibiting respectively different thermal expansion or contraction in response to change in temperature over the temperature range, thereby to adjust insulation performance of the textile fabric by changing three dimensional configuration of the textile fabric substrate gradually in response to gradual temperature changes in ambient conditions.
