GB/T 2403-2014 "Cationic dyes—Determination of applicable pH range of dye bath in dyeing acrylic fibers" is applicable to the determination of the applicable pH range of dye baths when dyeing acrylic fibers with cationic dyes. The standard specifies a detailed test procedure, requiring the use of a pH meter to precisely adjust and monitor the pH value of the dye bath. By controlling the dyeing conditions with dyeing equipment and comparing the dyeing effects under different pH values, the optimal pH range of the dye bath is determined, providing technical reference for optimizing acrylic fiber dyeing processes and dye selection.
