摘　　要：文章对耐唾液色牢度新旧标准唾液配方分别进行试验,分析新旧标准的不同和试验结果的差异,选取不同颜色、纤维成分的20组样品进行新旧标准试验程序对比,结果表明:大部分样品变色沾色评级结果一致;部分样品用新标准唾液配方比旧标准唾液配方的评级更低。其中,含丝或毛等蛋白质纤维的试样评级更低推测是因为旧标准唾液配方溶液的pH偏酸性,对羊毛等蛋白质纤维存在一定影响。This paper respectively tests saliva formula of the color fastness of the new and old standard saliva tolerance to analyze the difference between the old and new standard and the difference of the test results. Twenty groups of samples with different colors and fiber components are selected to compare the old and new standard test procedures. The results show that most of the samples have the same grading results of discoloration and staining;some samples used the new standard saliva formula have a lower rating than the old standard saliva formula. Among them, the lower grade of samples containing protein fibers such as silk or wool may be due to the assumption that the pH of the old standard saliva formula solution is slightly acidic, which have some impact on protein fibers such as wool.
