This standard specifies a method for determining the directness of KN and M dyestuff reactive dyestuffs. Directness is assessed by dyeing cotton fibers and calculating the percentage of dyestuff over a 30-minute dyeing time, reflecting the adsorption capacity of dyestuff on fibers. The standard is suitable for evaluating the dyeing effect of reactive dyestuffs and provides a technical basis for the performance evaluation of dyestuffs.
