Influence of Ultrasonic Radiation on the Dyeing of Cotton Fabric Using Reactive Yellow 145 Dye

ANSTRACT

Ultrasonic (US) radiation has a promising effect in textile processing due to its eco-friendly nature, rapid, cost and time effective tool. For the present study, the cellulosic fabric and dye solution were irradiated with ultrasonic (US) radiation for different times (10–60 min.). Dyeing was performed using nonradiated and irradiated cellulosic with nonradiated and irradiated Reactive Yellow 145 dye. Different dyeing parameters such as temperature, pH, material to liquor ratio and time were optimized using irradiated dye and irradiated cotton. It is found that US treatment of dye solution for 20 minutes gives good color strength by dyeing un-irradiated fabric at 70 °C, for 35 min using dye bath of pH 9 in the presence of 5 g/100 mL of salt as exhausting agent keeping 40 mL of dye volume. Colorfastness properties of fabrics dyed at optimum condition of various shades show that US treatment has improved the grading of fastness from fair to good. It is found that US irradiation had not only enhanced the strength of dye on irradiated fabric but also improved the dyeing properties. It is also concluded that US treatment has not only reduced the dyeing time, temperature but also reduced the amount of salt and dye volume used, which is the proof that this tool is cost, time and energy effective.

摘要

由于超声波（US）辐射具有环保、成本低、时间效率高等特点，它在纺织品加工应用中富有前景。在本研究中，用超声波（US）辐射对纤维素织物和染料溶液照射不同时间段（10-60分钟），然后分别用未照射和经过照射的活性黄145染料对未照射和经过照射的纤维素进行染色，使用经过照射的染料和经过照射的棉来优化不同染色参数，例如温度、pH值、材料/液体比率以及时间。研究发现，经过 20 分钟超声波处理的染色溶液，在5克/100毫升盐液作为排出剂并保持 40 毫升染料体积的条件下，用pH 9的染浴在70℃下对未照射的织物染色 35 分钟，可得到良好的着色强度。在各种色调的最佳条件下染色的织物的色牢度性质表明，超声波处理将色牢度的等级从“尚可”改善为“良好”。研究还发现，超声波照射不仅增强了经照射织物上染料的强度，还改善了染色性能。由此我们得出结论：超声波处理不仅能缩短染色时间、降低温度要求，而且能减少所使用的盐和染料体积的量，这证明超声波在成本、时间和能量效率上具有优势。
