Abstract

In this study, the effect of ionic liquids on the dyeing of cotton fabrics with reactive dyestuffs was investigated. For this purpose, 100% cotton fabrics were treated with imidazolium (1-ethyl-2,3-dimethylimidazolium ethyl sulfate- E) and ammonium (methyl-tri-n-butylammonium methyl sulfate- B) based ionic liquids with three different concentrations. To assess the effect of the treatments, the cotton fabrics were characterized by FT-IR, SEM and DSC. After this treatment, the cotton fibers were dyed with 1.0% o.w.f reactive dye. The K/S values were determined to evaluate the effect of ionic liquids on the dyeability of cotton fabrics and fastness analyses to washing, water and rubbing were conducted to examine the end-use properties of dyed fabrics. The results revealed that ionic liquids settled on the fabric surface and after each ionic liquid modification, the increasing intensity was observed with increasing ionic liquid concentrations at broad bands according to the FT-IR analysis. It was determined that the K/S value of the modified cotton fabric increased with increment in the concentration of ionic liquid E, especially. Considering the overall results, it is possible to state that ionic liquids which are implemented in this study are efficient in enhancing the dyeability of the cotton fabrics.

咪唑和氨基离子液体用于活性染料提高棉纤维可染性的研究

研究了离子液体对活性染料对棉织物染色的影响。为此，用三种不同浓度的咪唑鎓（1-乙基-2,3-二甲基咪唑鎓-乙基硫酸酯-E）和铵（甲基-三丁基铵-甲基硫酸酯-B）基离子液体处理100%纯棉织物。为了评价处理的效果，用FT-IR、SEM和DSC对棉织物进行了表征。处理后，用1.0%活性染料对棉纤维进行染色。测定K/S值以评估离子液体对棉织物可染性的影响，并进行耐洗涤、耐水和耐摩擦牢度分析以检验染色织物的最终使用性能。结果表明，离子液体沉积在织物表面，根据FT-IR分析，在每次离子液体改性后，在宽频带上观察到随着离子液体浓度的增加，强度增加。结果表明，改性棉织物的K/S值随着离子液体E浓度的增加而增加，尤其是随着离子液体浓度的增加。考虑到总体结果，可以说明本研究中使用的离子液体在提高棉织物的可染性方面是有效的。
