GB/T 2391-2014 "Reactive dyes - Determination of fixation rate" specifies the method for determining the fixation rate of reactive dyes dyed or printed on cellulose fibers. This standard calculates the proportion of dye that has formed covalent bonds with the fiber by comparing the change in the amount of dye in the dyebath before and after dyeing, or by measuring the amount of unfixed dye eluted from the fiber. It serves as a key indicator for evaluating the application performance of reactive dyes.
