摘　　要：针对活性染料对天丝和亚麻上染性能的差异，试验了中温型活性染料用量，染色温度，Na2SO4和Na2CO3用量，以及固色时间等因素对天丝／亚麻混纺织物同色性的影响。通过正交试验，优化了染色工艺。在染料1％～4％（omf），染色温度80℃，Na2SO4质量浓度40g／L，Na2CO3质量浓度15g/L，固色时间55min的工艺条件下，天丝／亚麻混纺针织物能获得良好的同色性及较高的染色牢度。Owing to the differences of dyeing properties of Tencel and linen fibers, the effects of the con- centration of reactive dyes, dyeing temperature, concentration of salt and alkali as well as fixing time on the union dyeing property of Tencel/linen knitting fabrics are discussed. The optimum dyeing process of deep shade Tencel/linen knitting fabrics with reactive dyes is determined through orthogonal experiments. The results indicate that the Tencel blends have good union dyeing property and high color fastness under the condition of dyes 1%-4% （omf）, Na2SO4 40 g/L and Na2CO3 15 g/L at dyeing temperature 80 ℃ and fixing time 55 min.
