• Dye affinity of levelling agent

  Principle of action: When the affinity of the levelling agent to the dye is greater than the affinity of the dye to the fiber, before the dye is adsorbed by the fiber, the levelling agent first pulls the dye, and then combines to form a stable aggregate, and the dye is separated from the levelling a
