Abstract
A multilayer fabric for selectively blocking or transmitting particular wavelengths in the electromagnetic spectrum, such solar radiation, and far infrared (FIR) radiation. The multilayer fabric may include a microporous water vapor permeable layer that selectively filters particular wavelengths depending on the size of its pores. In some embodiments, the multilayer fabric may include a nanostructured layer that selectively filters particular wavelengths.
Claims8
A multilayer fabric, comprising:
- a microporous water vapor permeable layer comprising:
- a microporous membrane coated with a metallic layer, the metallic layer comprising a metallic material and a thickness of 10 nanometers or less, and
- pores with a pore size in a range of 1.0 micron to 14.0 microns, wherein the pores allow the transmission of far infrared (FIR) radiation and solar radiation, and wherein the pores are arranged in a repeated and consistent pattern;
- a first textile layer coupled to the microporous water vapor permeable layer;
- and
- a second textile layer coupled to the microporous water vapor permeable layer,
- wherein the microporous water vapor permeable layer is disposed between the first textile layer and the second textile layer.
