This standard specifies the method for determining the compatibility index of cationic dyes for dyeing acrylic fibers using the contrast dyeing method. The core principle involves using two sets of standard dye samples, yellow and blue, each containing five dyes with compatibility indices graded from 1 to 5. The test dye is mixed and dyed separately with the set that exhibits a greater difference in color tone. By comparing the colors of the dyed samples, the compatibility index of the test dye is determined, where the same index indicates consistent compatibility performance. This method serves as a fundamental approach for evaluating the compatibility of dyes in mixed dyeing. The testing instruments mentioned in the standard primarily include analytical balances for precise weighing and laboratory dyeing machines.
