Measurement of the Coefficient of Absorption and Reflection in Textile Materials with the Model Spctral2

The chemical staining treatment on a textile material, define the color of each one. The dark color with a very low reflectance value, tend to reflect less light and absorb more thermal energy, on the other hand the light color with high reflectance value absorb less thermal energy. In this paper, with the SPCTRAL2 model describes that the solar irradiance flux that reaches the terrestrial surface, we calculate the absorption and reflection coefficients of certain textile materials of different colors.
