桑蚕丝上染料光褪色机理研究 Ⅰ.氨基酸在染料光褪色中的作用

Light Fading Mechanism of Dye on Reai Silk I. The Action of Amino Acid on Light Fading of Dye

应用类似于Stern-Volume方程的荧光测定及光褪色动力学试验,研究桑蚕丝模拟化合物—氨基酸对染料光褪色的影响。结果表明,色氨酸能显著加速染料光褪色,色氨酸具有敏化单线态氧能力,并表明使用抑制单线氧的金属络合物,能抑制桑蚕丝上染料光褪色。

The action of simulate silk compound-amino acid on light fading of dye is studied by means of the fluorescence spectrometric experiment, applying Stern-Volume equation and light fading kinetic testing. With the result that trypro-phane,with the ability of sensibilizing single oxygen, can obviously accelerate the light fading of dye, and that light fading of dye can be retarted by some metal complexes.
