We report here the synthesis and characterisation of a new medium‐reactivity reactive dye containing 2‐sulphophenoxy‐4‐chloro‐s‐triazine, having enhanced the activity of the chlorine atom for further substitution by the functional groups carried by wool fibre. In addition, a dichloro‐s‐triazine dye was also synthesised for the purpose of comparison. The progress of synthesis reactions and purity of the dyes were determined using capillary electrophoresis and thin layer chromatography. The molecular structure and the chemical compositions of the synthesised dyes were confirmed using Fourier Transform–infrared spectral data and elemental analyses. The inks containing the synthesised dyes were formulated and ink‐jet‐printed onto wool fabrics and then the printed fabrics were steamed at 102°C. Compared with the dichloro‐s‐triazine dye, superior performance in terms of ink stability, K/S and dye fixation was observed for the new 2‐sulphophenoxy‐4‐chloro‐s‐triazine dye. In addition, the light fastness of the fabric printed with the inks containing the new dye was 0.5‐grade greater than that of the fabric printed with the inks containing the dichloro‐s‐triazine dye, and no changes in shade and staining were observed following wash fastness tests of the fabrics printed with the inks containing the new dye.

用于羊毛喷墨印花的新型2-硫代苯氧基-4-氯-s-三嗪活性染料的合成、稳定性和印花性能

我们在此报告了一种含有 2-sulphophenoxy-4-chloro-s-triazine 的新型中等反应活性染料的合成和表征，该染料增强了氯原子的活性，以进一步被羊毛纤维所携带的官能团取代。此外，为了比较，还合成了二氯-s-三嗪染料。使用毛细管电泳和薄层色谱法测定合成反应的进程和染料的纯度。合成染料的分子结构和化学成分通过傅立叶变换-红外光谱数据和元素分析得到证实。将含有合成染料的油墨配制并喷墨印花到羊毛织物上，然后将印花织物在 102°C 下蒸煮。与二氯-s-三嗪染料相比，新的 2-sulphophenoxy-4-chloro-s-triazine 染料在油墨稳定性、K/S 和染料固色方面表现出色。此外，用含有新染料的油墨印刷的织物的耐光牢度比用含有二氯-s-三嗪染料的油墨印刷的织物高0.5级，并且没有观察到色调和染色的变化。用含有新染料的油墨印刷的织物的耐洗牢度测试。
