摘要
本试验在模拟日光照射下,研究了真丝绸的泛黄机理。结果表明,泛黄真丝绸的黄度指数与氙灯照射时间之间是乘幂函数关系,泛黄真丝绸中的色氨酸、组氨酸及酪氨酸的损失百分率最大。其中色氨酸与酪氨酸是引起真丝绸泛黄的关键氨基酸;泛黄真丝绸的黄度指数增值与色氨酸损失率、酪氨酸损失率之间均呈线性关系,并分别求得了它们的线性方程式。
The yellowing mechanism of irradiation of silk fabric with xenon lamp has been studied. The relation between yellowness index and time of irradiation is a power function. After irradiation,the most decreased amino acids are corresponding to tryptophan, histidine and tyrosine. Tryptophan and tyrosine play an important role in the yellowing of silk. The results also showed the relations between the increase of yellowness index and the decrease ratio of tryptophan and tyrosine are liner function. Moreover,these two liner equations were obtained respectively.
