文摘The effect of simulated silk compounds- amino acids and their yellowing substances onphotofading of ary1methane dyes.and the influence of external factors such as oxygen.pH-value.the wave band of light source and nickel salt on phototfading of the dyes on real silkare investigated. The results show that tryptophan and tyrosine well as their yellowing sub-stances accelerate photofading of arylmethane dyes;the photofading process of arylmethandyes on real silk is a photooxidation process and external factors exert different influences onit.
