The pad dyeing of polyester-cotton blend fabric was discussed according to the influences of curing temperature, curing time, electrolyte consumption, soda ash and steaming time on the fabric weight and soaping fastness. The optimum process was as follows: curing temperature 200 ℃, curing time 100 s, Na2CO3 30 g/L, NaCI 200 g/L. The pad dyeing effect of under this process was good and the washing fastness was over 4 grade, the levelness △E was 1.0.%通过探讨焙烘温度、焙烘时间、电解质用量、纯碱用量、汽蒸时间对织物单位面积质量和皂洗牢度的影响,优化涤棉轧染工艺.最佳工艺为:焙烘温度200℃,焙烘时间100s,Na2CO3用量30 g/L,NaCl用量200 g/L.此工艺条件下,染料的上染效果较好,皂洗牢度在4级以上；匀染性较好,△E为1.0.
