GB/T 21880-2015 "Acid Dyes - Determination of Migration Property" is applicable to the determination of the migration property of acid dyes, acid-complex dyes, and neutral dyes. The method involves dyeing fabric with the dye using a laboratory dyeing machine, followed by adding white fabric for migration treatment. A spectrophotometer is used to measure the color depth of the white fabric after migration and the original dyed fabric. The migration degree is evaluated by calculating the percentage of the two values, with specified parameters such as dyeing and migration temperature and time.
