摘　　要：探讨了二价铜离子对分散红3B染色性能的影响,研究了二价铜离子存在时助剂TA(三聚氰胺)和CD(β-环糊精)对分散红3B染色性能的影响.结果表明:铜离子对分散红3B染料吸光度和染色K/S值的影响很大,K/S值的下降与铜离子浓度有关,容易引起色光向短波长偏移且得色变浅.而助剂TA和CD会使分散红3B的吸光度和K/S值下降,但是有利于染色织物色相的稳定性.The influence of divalent copper ions on the dye properties of Disperse Red 3B was discussed, and the influence of additives TA （melamine） and CD （β-cyclodextrin） on the dye properties of Disperse Red 3B in the presence of divalent copper ions were studied. The results showed that： copper ions had a great influence on the absorbance of Disperse Red 3B and K/S value of the dyeing. The decrease of K/S value was related with the concentration of copper ion, which can easily lead to light shade of dyed samples and the short-wavelength shift. In the presence of auxiliaries （TA and CD）, absorbance of Disperse Red 3B and K/S value of the fabrics dyed with Disperse Red 3B were decreased, but the stability of the hue for dyed fabric was good.
