GB/T 4464-2016 "Dyes—Determination of migration property" is applicable to the testing of migration performance of various dyes and specifies the specific determination method. After applying the dye liquor to the fabric and drying it under specific temperature and humidity conditions, a spectrophotometer is used to measure the color difference in different areas of the fabric to evaluate the degree of dye migration. It clarifies the sample preparation, drying conditions, and color difference calculation methods. The deviation of parallel test results must meet the requirements, providing a basis for controlling migration issues in dye applications.
