摘　　要：为开发腈纶染色用环保型缓染剂,采用3只咪唑类离子液体作为亚甲基蓝上染腈纶纤维的缓染剂,并与常规缓染剂十六烷基三甲基溴化铵(CTAB)作比较,探究上述离子液体对亚甲基蓝上染腈纶纤维的影响。通过对缓染剂用量、染色温度和升温上染曲线的研究,以及染色转变温度的比较,探究出不同结构离子液体的缓染性能规律。结果表明,不对称烷基咪唑类离子液体对腈纶亚甲基蓝染色具有一定的缓染作用,随离子液体烷基碳链的增长,缓染作用不断增加,离子液体对染料最终上染率有一定的影响,但影响程度与常规缓染剂CTAB相近,可作为腈纶染色时优良的缓染剂。In order to development environment-friendly retarding agent for acrylic fiber dyeing,three imidazolium-based ionic liquids were used as retarding agent for methylene blue dyeing of acrylic fabrics.And the dyeing performance was compared with conventional retarding agent cetyltrimethy-lammonium bromide（ CTAB）. The retarding dyeing laws of were explored by dosage of retarding agent,dyeing temperature and dyeing rate curves. It was found that the retarding dyeing performance was increased with the increasing of alkyl carbon chain. The addition were decreased the final dyeing uptake of acrylic fabrics,but the same effect obtained by CTAB. Imidazolium-based ionic liquids imidazolium tased inonic liquids can be used as a excellent retarding agent for dyeing of acrylic fabrics.
