Abstract

A textile includes: (1) a matrix; and (2) particulate fillers dispersed within the matrix. The textile has a transmittance of infrared radiation at a wavelength of 9.5 μm of at least about 40%, and the textile has a weighted average reflectivity of radiation over a wavelength range of 0.3 μm to 2 μm of at least about 40%.
