摘　　要：由于荧光增白剂的特殊光学性能,使得含有荧光增白剂的织物配色困难。通过分析荧光增白剂的反射率曲线,应用发射区荧光染料的反射率计算公式,研究了荧光增白剂的配色方法,提出了荧光增白剂计算机配色的三波段法———即对荧光增白剂的配色分发射区、激发区和无影响区分别进行。通过20个拼色试样的染色实验和计算,证明本方法适用于荧光增白剂的配色,且方法简便。最大色差为3.94。Since fluorescent whitening agent （FWA） has unique optical properties, its color matching for fabrics is difficult. The researchers developed the color matching method of FWA through analyzing its reflectance curve and utilizing a computation formula of the reflectance of fluorescent dyes in the emission region and put forward the three-region （emission, absorption and unaffected） method of color matching . It was proved by dyeing experiments of 20 samples of mixed colors and relative computation that this color matching method is suitable for FWA. The operation is simple and convenient and the maximum color difference is 3.94 CIELAB1976 units.
