Disperse dyestuffs - Determination of property of staining cotton

GB/T 2398-2012 "Disperse dyes - Determination of staining on cotton" specifies the method for determining the staining properties of disperse dyes on cotton fabric during high-temperature and high-pressure dyeing or thermosol dyeing of polyester fabric. The principle involves dyeing cotton fabric in contact with polyester fabric, then comparing the color difference between the original white cotton and the stained cotton to assess the staining grade. The test requires equipment such as a high-temperature and high-pressure dyeing machine, a thermosol dyeing machine, a colorimeter, and an electronic balance, with strict control over dyeing conditions. This standard provides a quality basis for controlling staining contamination in the application of dyes.
