合成了溴基和乙酸基离子液体(ILS)、1-丁基-3-甲基咪唑溴([Bmim]BR)、1-乙基-3-甲基咪唑溴([EMIM]BR)、1-丁基-3-甲基咪唑乙酸酯([Bmim]Ac)和1-乙基-3-甲基咪唑乙酸酯([Emim]Ac)，并将其用于羊毛表面处理。扫描电子显微镜结果表明，经乙酸化的ILS处理的羊毛表面受到的侵蚀比经溴化的ILS处理的羊毛表面的腐蚀更严重。对比研究表明，醋酸酯基离子液体处理的羊毛样品，特别是[EMIM]Ac处理的羊毛样品，其初始上染率和平衡上染率高于溴基离子液体。随着处理温度和时间的增加，醋酸酯基离子液体对羊毛的力学性能和染色性能的影响比溴基离子液体更为显著。经[EMIM]Ac在60℃下处理10min的羊毛样品具有优良的低温染色性能。色深(K/S)研究表明，醋酸酯基离子液体处理的羊毛样品比溴基离子液体处理的羊毛样品具有更深的色深。经[Bmim]BR、[Emim]BR和[Bmim]Ac处理的羊毛样品的色牢度与未处理的样品相同，而[Emim]Ac处理的样品的湿色牢度略有下降。©2011 Wiley期刊，Inc.J Appl Polym Sci，2012
Bromo-based and acetated-based ionic liquids (ILs), 1-butyle-3-methylimidazolium bromo ([Bmim]Br), 1-ethyl-3-mthylimidazolium bromo ([Emim]Br), 1-butyle-3-methylimidazolium acetate ([Bmim]Ac), and 1-ethyl-3-mthylimidazolium acetate ([Emim]Ac), were synthesized and employed for wool surface treatment. Scanning electron microscope results indicated that the wool surfaces treated with acetated-based ILs were eroded more than those treated with bromo-based ILs. Comparable studies showed that the wool samples treated with acetate-based ILs, especially [Emim]Ac, had higher initial dyeing rate and equilibrium exhaustion than those with bromo-based ILs. Along with treatment temperature and time increasing, acetate-based ILs had more remarkable effects on mechanical and dyeing properties of the wool samples than bromo-based ILs. The wool samples treated with [Emim]Ac at 60°C for 10 min had excellent low-temperature dyeing properties. The color depth (K/S) investigations showed that the wool samples treated with acetate-based ILs possessed darker color depth than those treated with the bromo-based ILs. Color fastnesses of the wool samples treated with [Bmim]Br, [Emim]Br and [Bmim]Ac exhibited the same grades as the untreated sample, while wet color fastnesses of [Emim]Ac treated sample were slightly decreased. © 2011 Wiley Periodicals, Inc.
