In this work, thiazole based azo dyes (6A and 6B) and anthraquinone dye derivatives (6C, 6D and 6E) were synthesized from commercially inexpensive starting materials.The advantage of the synthesis of these dyes are quite facile and scale-up is feasible, which favors for an industrial dyeing applications. All the dyes were characterized by spectroscopic techniques such as IR, NMR (¹H and ¹³C), HRMS and UV–vis spectroscopy. Preliminary dyeing experiments were carried out with these dye stuffs on nylon 6,6 fabrics to examine the possibility of scaling up supercritical carbon dioxide dyeing to a factory level. All the five dyes (6A-6E) showed good color strength and especially two dyes 6A and 6C exhibited excellent dye fixation. Remarkable results obtained for washing fastness (fading and staining grade of 4–5) and sweat fastness (fading and staining grade of 4–5) for all the dyes (6A-6E). Based on the results, the synthesized dyes could be hopefully applied in near future for the dyeing of nylon 6,6 fabrics on an industrial scale under the ecofriendly and energy-efficient supercritical carbon dioxide medium.

在这项工作中，由市售廉价的原料合成了噻唑基偶氮染料（6A和6B）和蒽醌染料衍生物（6C，6D和6E），这些染料合成的优点是很容易实现，并且可以放大应用，有利于工业染色应用。所有染料均通过红外，核磁共振（¹ H和¹³ C），HRMS和紫外可见光谱等光谱技术进行了表征。对这些染料在尼龙6,6织物上进行了初步染色实验，以检查将超临界二氧化碳染色扩大到工厂水平的可能性。全部五种染料（6A-6E）染料显示出良好的色强度，特别是两种染料6A和6C表现出优异的固色性。所有染料（6A-6E）的耐洗牢度（褪色和染色等级为4-5）和耐汗牢度（褪色和染色等级为4-5）获得了显着结果。基于这些结果，合成染料有望在不久的将来应用于环保，节能的超临界二氧化碳介质下工业规模的尼龙6,6织物的染色。
