Abstract
The three chromic dyes having alkyl groups symmetrically or asymmetrically substituted on azobenzene chromophore were synthesized and investigated in their color change by exposure to acid gas like hydrochloric acid in order to produce acid-gas sensing fabrics. By the specially designed dynamic color measurement system, the color change of the dyed fabrics by exposure to hydrochloric acid gas was measured in real time. The Dye(8,2,2) of the three dyes was determined as the best one considering synthesis and purification process, heat resistance, sensitivity to acid gas, and fastness on fabrics altogether. Even at very low concentration of hydrochloric acid, the color of dyed fabrics changed substantially from bright yellow to strong red. Since the color change of the dyes can be returned to its original color by ventilation, they are reusable repeatedly without significant decrease its sensing property. The fastnesses to washing, rubbing, and light were considerably good enough for practical applications.
