The GB/T 33795-2017 standard specifies a method for the determination of the hydrolysis rate of reactive dyestuff during the dyeing process. The hydrolysis rate of dyestuff is calculated by dyeing on cotton fibres and measuring the Peak area of the hydrolysis product using a liquid chromatograph. The standard applies to KN-type and M-type reactive dyestuff to help evaluate the Stability and performance of dyestuff during the dyeing process to ensure its application effect and dyeing mass.
