1. A textile comprising:
a matrix comprising at least one of polyethylene or polypropylene; and
particulate fillers dispersed within the matrix, wherein the particulate fillers have an average particle size in a range of about 500 nm to about 900 nm, and a number density of the particulate fillers is 0.1 to 0.5 μm−3, wherein the particulate fillers include at least one of potassium bromide, cesium iodide, potassium chloride, or sodium chloride,
wherein the textile has a transmittance of infrared radiation at a wavelength of 9.5 μm of at least 40%, and
wherein the textile has a weighted average reflectivity of radiation over a wavelength range of 0.3 μm to 2 μm of at least 40%.
