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?

ISBU Report on Ceramic Coatings
· Emissivity: the ability of an object or surface to emit or deflect Infrared (IR) energy. Their emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most surfaces have emissivity values close to 0.95. Absorption and deflection are a simple way to think of emissivity. A shiny mirror deflects heat and energy and is rated Low-e.
