In this research, to study the difference of photofading curves and photofading of different basic dyes illuminating basic dyes which mixed Meta-phenylene diamine and Isophthaloyl chloride in quartz cells. Dyeing Nomex fabric with different basic dyes, to study photofading curves and photofading rate of Nomex fabric after illuminating it. The results indicate that the influence of photofading cures and photofading rate of methane and monoazo basic dyes is adding Isophthaloyl chloride> Meta-phenylene diamine and Isophthaloyl chloride > Meta-phenylene – diamine. The influence of photofading cures and photofading rate of thiarylmethane and others basic dyes is adding Meta-phenylene diamine > Meta-phenylene diamine and Isophthaloyl chloride> Isophthaloyl chloride. Photofading curves on Nomex fabric and in D.M.F of basic dyes are the same.
