Colorimetric Properties of Photochromic Textiles

Abstract:

Photochromism is a chemical process in which a compound undergoes a reversible change between two states having separate absorption spectra, i.e. different colors. The change of color in one direction occurs under influence of electromagnetic radiation, usually UV light, and in the other direction by altering or removing the light source or alternatively by using thermal means. Based on photochromic pigment we developed simple textile sensor sensitive to UV light, which is usable for visual indication of intensity UV-A radiation. Main attention was given to colorimetric properties of photochromic textiles during decay phase of photochromic color change, such as saturation change and fatigue resistance.
