采用铜镍合金电极作为阳极，铜片作为阴极，研究了影响还原棕BR电化学还原染色工艺的主要因素，如外加电压（U）大小、氢氧化钠（NaOH）质量浓度、三乙醇胺（TEA）质量浓度、硫酸铁（Fe2（SO4）3）质量浓度、阴极面积、还原染色温度（T）、还原染色时间（t）等．通过分析实验结果，获得最佳电化学还原染色工艺，即外加电压3V ，NaOH、TEA 和Fe2（SO4）3的质量浓度依次为8g／L ，30g／L ，5g／L ，阴极面积25cm2，还原染色温度40℃，还原染色时间70min ．同时，测得在最佳工艺参数条件下棉织物染色后的 K／S值，得到ΔK／S＝0.668，说明该工艺参数条件下织物的匀染性良好，织物的皂洗色牢度和干湿摩擦牢度均能达到4～5级．
