摘　　要：采用阳离子改性增深剂WT对棉织物进行前处理，通过改变改性剂用量、改性温度、时间和NaOH用量，优化改性工艺。试验表明，改性剂WT用量为1．0％～2．0％（owf）、NaOH2．0～2．5g／L，70℃改性30min时，可提高活性染料的上染率，使棉织物染色深度和牢度达到较为理想的效果。The cationic modifier WT was used to cotton fabrics pretreatment. The modification process was optimized by changing the dosage of modifier and hydroxide sodium, as well as temperature and time. It was shown that the dye uptake,K/S values and color fastness of reactive dyed fabric were improved under the condition of modifier WT 1.0% 0 2.0% （owf）, NaOH 2.0 -2.5 g/L, and processing at 70 ℃ for 30 minutes.
