1-(3-aryl)-3-(dimethylamino)prop-2-en-1-one (enaminones) derivatives and the diazonium salt of -chloroaniline were used to synthesize several novel disperse azo dyes with high yield and the use of an environmentally friendly approach. At 100 and 130 °C, we dyed polyester fabrics using the new synthesized disperse dyes. At various temperatures, the dyed fabrics' color intensity was assessed. The results we obtained showed that dyeing utilizing a high temperature method at 130 °C was enhanced than dyeing utilizing a low temperature method at 100 °C. Reusing dye baths once or twice was a way to achieve two goals at the same time. The first was obtaining a dyed product at no cost, and the second was a way to treat the wastewater of dyeing bath effluents and reuse it again. Good results were obtained for the fastness characteristics of polyester dyed with disperse dyes. When the disperse dyes were tested against certain types of microbes and cancer cells, they demonstrated good and encouraging findings for the potential to be used as antioxidants and antimicrobial agents.
1-(3-芳基)-3-(二甲基氨基)丙-2-烯-1-酮（烯胺酮）衍生物和 -氯苯胺的重氮盐被用于以高产率和环保方法合成几种新型的分散偶氮染料。在 100 和 130°C 下，我们使用新合成的分散染料对聚酯织物进行染色。在不同温度下，评估了染色织物的颜色强度。我们得到的结果表明，在 130°C 下使用高温方法染色比在 100°C 下使用低温方法染色效果更好。重复使用染浴一到两次是同时实现两个目标的一种方法。第一个目标是免费获得染色产品，第二个目标是处理染色浴废水并再次重复使用它。用分散染料染色的聚酯的牢度特性得到了很好的结果。当测试分散染料对某些类型的微生物和癌细胞的作用时，它们显示出作为抗氧化剂和抗菌剂的潜在用途的良好和令人鼓舞的发现。
