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.
Claims20
A multilayer fabric, comprising:
- a microporous water vapor permeable layer comprising pores with a pore size in the range between 1.0 microns and 14.0 microns, wherein the microporous water vapor permeable layer is configured to allow the transmission of far infrared (FIR) radiation and solar radiation, and wherein the pores are arranged in a repeated and consistent pattern;
- and
- a first textile layer coupled to the microporous water vapor permeable layer.
An article of apparel, comprising:
- a multilayer fabric comprising:
- a microporous water vapor permeable layer comprising pores that are configured to 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, and wherein a first pore pattern of the microporous water vapor permeable layer in a first zone is different from a second pore pattern of the microporous water vapor permeable layer in a second zone.
