摘要: 为提高羊毛纤维的染色性能,采用对角蛋白具有溶解能力的1-丁基-3-甲基咪唑氯盐离子液体对羊毛纤维进行改性。通过研究不同时间预处理对纤维表面形态及其弱酸染料上染速率的影响可以发现:羊毛纤维经过离子液体处理后,表层鳞片遭到破坏,染色性能得到较大改善,而且随着处理时间的延长,鳞片破坏程度加深,上染率及上染速率都得到提高,可以实现低温染色。

Abstract: 1-butyl-3-methylimidazolium chloride ionic liquid which has a good solubility for wool keratin is used to improve the dyeability of wool fibers.The morphology and weak acid dye uptake rate of the wool fibers which had been subjected to ionic liquid treatment for different durations were investigated,and it was found that the scales of the treated wool fibers were eroded and their dyeability was improved considerably.The eroding degree of wool scales deepened and the dye uptake and dyeing rate improved as the time of treatment prolonged.Thus,modification of wool fibers using ionic liquid makes low temperature dyeing of wool possible.
