摘　　要：采用平幅轧烘轧蒸的连续染色工艺,对棉针织物进行活性染料染色。通过对常规染色试样、不均匀张力下轧烘和轧蒸的染色试样进行比较,研究张力对棉针织物平幅染色效果的影响,同时对活性染料在棉纤维中的分布和染色牢度进行评估。结果表明,张力对棉针织物平幅染色效果影响较大,活性染料在棉纤维截面上分布均匀,染色牢度好。Continuous open-width dyeing of cotton knitted fabrics using pad-dry-pad-steam process with reactive dye is carried out.The effect of tension on the open-width dyeing of cotton knitted fabrics is studied by comparing the conventional dyeing samples and the dyeing samples with non-uniform tension during pad-dry and pad-steam.The distribution of dyes in the cross section of the cotton fibers and the dyeing fastness are evaluated.The results show that tension has a great influence on the dyeing effect of cotton knitted fabrics,but the reactive dyes are well distributed in the cross section of the fibers and the knits have good dyeing fastness.
