摘　　要：针对活性染料冷轧堆染色效率低、深浓色布面黑气重等问题,采用无盐连续轧-蒸染色工艺对纯棉、天丝/棉交织物进行染色。借助稳定性分析仪表征染液的稳定性,将专用碱应用于SNE型活性染料轧-蒸染色,并与冷轧堆染色效果进行对比。结果表明:碱剂组成和时间均会影响染液稳定性和扩散性;含混合碱的染液放置10 min时,其稳定性指数为0.72,是含专用碱剂和色丽牢染液的2.6和2.1倍;专用碱剂和色丽牢可提高染液扩散性能;经无盐连续轧-蒸染色的军蓝色、咖啡色纯棉织物表观色深Integ值较冷轧堆染色织物分别提高2.9和2.7,染色织物的色牢度大于等于3级,符合生产要求;该染色工艺同样适用于天丝/棉交织物,其生产效率高,表观得色深。In view of the problem of low production efficiency,uneven dyeing in cold pad-batch dyeing process,the cotton fabrics and Tencel/cotton fabrics were dyed with reactive dyes using salt-free continuous pad-steam dyeing process.The stability of padding solutions were measured using AGS analyzer.The special alkali was used in pad-steam dyeing with the SNE reactive dyes,and the dyeing effect was compared with that of pad-batch dyeing.The results show that the stability and diffusion properties of dye solutions are affected by alkali composition and time.When the dyeing solution with mixed alkali is placed for 10 min,the stability index is 0.72,which are 2.6 and 2.1 times higher than that of dye solutions with special alkali and Selilao.The special alkali and Selilao can improve the diffusion performance of padding solutions.The Integ values of the dyed cotton fabrics（army blue and coffee） obtained from the salt-free continuous pad-steam dyeing process are 2.9 and 2.7 times higher than that of dyed fabrics using cold pad-batch dyeing process,respectively.The color fastness of dyed fabrics is more than 3 grade,which is in accordance with the production requirements.The salt-free continuous pad-steam dyeing process can also be used in reactive dyeing for Tencel/cotton union fabrics with the advantages of high productivity and darker color depth.
