聚酰亚胺阳离子染料载体染色性能
|
摘要
以阳离子蓝SD-GSL染料和载体PEA在高温高压下对聚酰亚胺织物进行染色,研究高性能聚酰亚胺纤维的染色性能。通过正交实验设计对载体、电解质和pH值3个染色影响因素进行了研究。结果表明,载体和电解质的加入可以提高聚酰亚胺的染色性能,染液pH值对染色效果影响较小。聚酰亚胺纤维在含有载体和电解质的染色体系染色后具有良好的耐洗和耐摩擦色牢度,染料与纤维原有金黄色遵循减法混色原则,染色后纤维的颜色得以改变。扫描电镜测试结果表明,高温高压载体染色对纤维的表观形貌未产生明显的影响;热重分析表明经载体染色后聚酰亚胺纤维保持了良好的热稳定性;聚酰亚胺纱线的强力拉伸断裂测试结果显示纤维的强力有所下降。
In this work, polyimide fibers were dyed with Basic Blue SD-GSL and carrier PEA at high temperature and pressure. An orthogonal experiment with three factors and two levels was designed to figure out the influence of carrier, electrolyte and pH value to the dyeing system. It turns out that dyeing properties of polyimide are improved with the addition of carrier and electrolyte, while pH value has little influence on the dyeing system. After dyeing with carrier and electrolyte, the K/S values of fibers are increased a lot. It is also found that dyeing fibers have a great washing and rubbing fastness. Other properties of dyed polyimide were also examined through SEM tests, TG analysis and breaking strength tests. It is found that there is almost no change on the morphology, fineness, and thermal stability, which suggest that the dyeing system has no influence on physical properties of polyimide fibers, but the breaking strength of carrier-dyed polyimide is decreased slightly.
