摘　　要：针对棉和粘胶纤维在活性染料染色过程中上染性能的差异，采用新型预聚体DyapolPED250对粘胶／棉交织物进行预处理。优化的工艺条件为：预聚体DyapolPED2503％（omf）、处理温度60～65℃、处理时间20．30min、浴比1：20；再结合筛选的活性染色工艺，可使染得的粘胶，棉交织物具有较好的同色性和较高的色牢度。In view of the different dyeing performance of cotton and viscose fiber in union dyeing OT vis- cose/cotton fabric with reactive dyes, pretreatment of viscose/cotton fabric with Dyapol PED is carried out. The optimal process is： 3%（omf） of prepolymer Dyapol PED 250, pretreatment at 60 - 65℃ for 20 30 rain with bath ratio 1 ： 20. The viscose/cotton reactive dyeings feature good union color and high color fastness.
