    Reactive dyes—Determination of shade and relative strength—Low salt dyeing method

    GB/T 33788-2017 "Reactive dyes - Determination of shade and strength - Low salt dyeing method" specifies the method for determining the shade and strength of reactive dyes using low salt dyeing. It is applicable to the quality inspection of related reactive dyes. Dyeing is performed at a bath ratio of 1:20, from room temperature to 80°C, for 90 minutes. The shade and strength are evaluated by comparison with a standard sample. The test requires the use of specified dyeing equipment, an electronic balance, and volumetric flasks, while also complying with the relevant requirements for reagents and instruments in GB/T 2374-2017, meeting the environmental and testing needs of low salt dyeing.
