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.

First claim

What is claimed is:

1. A multilayer fabric, comprising:
a microporous water vapor permeable layer comprising a metallic layer comprising a metallic material, 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.

2. The multilayer fabric of claim 1 , wherein the microporous water vapor permeable layer consists of the metallic layer.

3. The multilayer fabric of claim 1 , wherein the microporous water vapor permeable layer is configured to allow the transmission of no less than 90% of solar radiation.

4. The multilayer fabric of claim 1 , wherein the microporous water vapor permeable layer is configured to allow the transmission of no more than 10% of FIR radiation.

5. The multilayer fabric of claim 1 , wherein the microporous water vapor permeable layer is configured to allow the transmission of no more than 10% of FIR radiation having a wavelength in the range of 8 microns to 12 microns.

6. The multilayer fabric of claim 1 , wherein the pores of the microporous water vapor permeable layer comprises a pore density of at least 5,000 pores per mm 2 .

7. The multilayer fabric of claim 1 , wherein a deviation of the pore size of the pores in the microporous water vapor permeable layer is +/−1.0 microns or less.

8. The multilayer fabric of claim 1 , wherein the metallic layer comprises a thickness in a range of 7.5 angstroms to 10 nanometers.

9. The multilayer fabric of claim 1 , wherein the metallic layer comprises a metallic coating comprising a thickness in a range of 7.5 angstroms to 10 nanometers and the metallic material is selected from the group consisting of: aluminum, titanium, silver, copper, gold, zinc, cobalt, nickel, platinum, and an alloy thereof.

10. The multilayer fabric of claim 1 , wherein the microporous water vapor permeable layer comprises a polymeric microporous membrane.

11. The multilayer fabric of claim 1 , further comprising a substrate layer coupled to the first textile layer, wherein the metallic layer is disposed on a surface of the substrate layer.

12. The multilayer fabric of claim 11 , wherein the metallic layer is deposited on the surface of the substrate layer.
