In this study,dyeing of elastane/spandex fiber with direct dyes and its dyeing behavior on elastane/spandex filament were investigated for better control of dye application properties and performance in the dyeing.The dyed sample was also studied by Fouri%为更好地控制染料的应用性能和在染色中的性能,研究了直接染料上染聚氨酯弹性纤维及其长丝的染色性能。被染样品通过傅里叶变换红外光谱加以分析,获得的动力学和热力学研究结果与傅里叶变换红外分析结果一致。
