In this research, a hybrid ink of reactive dye and cationic modifier 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) was developed. The zeta potential and stability of the hybrid ink have been specifically studied. By careful selection, the stability of the hybrid ink was improved with the surfactant Tween-80, proved by the calculations of binding constants and frontier molecular orbitals as well as the electrostatic potential maps. Importantly, the hybrid ink indicated good storage stability by analyzing the surface tension, viscosity, and pH value of the ink in a period of 90 days, meeting the requirements of commercial application. The K/S value of the cotton fabric printed with the hybrid ink (containing 30% CHPTAC) was 21.68 and the dye fixation was 91.56%, which were separately 35.33% and 26.85% higher than those of the cotton fabric printed with the reactive dye ink without CHPTAC. The higher dye fixation is beneficial to significantly reduce the content of hydrolyzed dyes in the wastewater, reducing the environmental pollution. Moreover, the fabrics inkjet printed with the hybrid ink presented a good colorfastness to laundering or crocking.

在这项研究中，开发了一种活性染料和阳离子改性剂3-氯-2-羟丙基三甲基氯化铵（CHPTAC）的混合油墨。已经特别研究了混合油墨的ζ电位和稳定性。通过精心选择，表面活性剂Tween-80改善了混合油墨的稳定性，这是通过计算结合常数和前沿分子轨道以及静电势图证明的。重要的是，通过分析90天之内墨水的表面张力，粘度和pH值，该混合墨水显示出良好的存储稳定性，满足了商业应用的要求。用混合油墨（含30％CHPTAC）印刷的棉织物的K / S值为21.68，固色率为91.56％，分别为35.33％和26。比使用无CHPTAC的活性染料墨水印刷的棉织物高85％。较高的固色率有利于显着降低废水中水解染料的含量，减少环境污染。此外，用混合油墨喷墨印刷的织物表现出良好的耐洗色或耐色牢度。
