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.

Claims

1. An article of apparel, comprising:

a multilayer fabric comprising;

a microporous water vapor permeable layer comprising pores that allow the transmission of far infrared (FIR) radiation and solar radiation; and

a textile layer coupled to the microporous water vapor permeable layer,

wherein the multilayer fabric comprises a plurality of zones,

wherein a first zone of the microporous water vapor permeable layer comprises a first pore pattern and a second zone of the microporous water vapor permeable layer comprises a second pore pattern,

wherein the first pore pattern in the first zone comprises a first pore size range that allows the transmission of a first percentage of FIR radiation and the second pore pattern in the second zone comprises a second pore size range which is different from the first pore size range and allows the transmission of a second percentage of FIR radiation,

wherein the pores of the microporous water vapor permeable layer in first pore pattern and the second pore pattern have a pore size in a range of 1.0 micron to 14.0 microns,

wherein the pores in the first pore size range have a first average pore size,

wherein the pores in the second pore size range have a second average pore size greater than the first average pore size, and

wherein the first percentage of FIR radiation is greater than the second percentage of FIR radiation.

2. The article of apparel of claim 1, wherein the textile layer comprises a first textile layer, wherein the multilayer fabric further comprises a second textile layer, and wherein the microporous water vapor permeable layer is disposed between the first textile layer and the second textile layer.

3. The article of apparel of claim 1, further comprising a nanostructured layer.

4. The article of apparel of claim 1, wherein the microporous water vapor permeable layer comprises a metallic material.

5. The article of apparel of claim 1, wherein the microporous water vapor permeable layer consists of a metallic material.

6. The article of apparel of claim 1, wherein the article of apparel is selected from the group consisting of:

a shirt, pants, shorts, leggings, a sock, a jacket, a coat, a hat, a sleeve, a shoe, a sweater, a jersey, and a glove.

7. The article of apparel of claim 1, wherein the first pore pattern in the first zone further comprises a different pore density than the second pore pattern in the second zone.

8. The article of apparel of claim 7, wherein the first pore pattern in the first zone comprises a pore density of at least 5,000 pores per mm² and the second pore pattern in the second zone comprises a pore density of at least 5,000 pores per mm².

9. The article of apparel of claim 1, wherein the first pore pattern in the first zone allows the transmission of no less than 90% of solar radiation.

10. The article of apparel of claim 1, wherein the first pore pattern in the first zone allows the transmission of no more than 10% of FIR radiation.

11. The article of apparel of claim 1, wherein the first pore pattern in the first zone allows the transmission of a first percentage of FIR radiation having a wavelength in the range of 8 microns to 12 microns and the second pore pattern in the second zone allows the transmission of a second percentage of FIR radiation having a wavelength in the range of 8 microns to 12 microns.

12. The article of apparel of claim 11, wherein the first pore pattern in the first zone allows the transmission of no more than 10% of FIR radiation having a wavelength in the range of 8 microns to 12 microns.

13. The article of apparel of claim 1, wherein the pores in first zone and the second zone are open pores extending through the microporous water vapor permeable layer, and the pore size of each pore is defined by a diameter of the open pore.

14. The article of apparel of claim 1, wherein a deviation in pore size for the pores of at least one of the first pore pattern or the second pore pattern is +/−

1.0 microns or less.
