High emissivity coating for textile surfaces

High emissivity factor, I understand relates to the amount of incoming radiation that is absorbed by the body as compared to a totally black body. Therefore if I seek to increase the UV or heat absorbtivity and increase the IR radiation given out would the use of a high emissivity coating (like oil paints, zirconium silicate, etc.) work?
