摘　　要：为开发新型涤纶碱减量促进剂及其应用工艺,提高涤纶碱减量的加工效率,采用3种烷基咪唑类双子型Gemini离子液体作为涤纶碱减量加工促进剂,并与常规阳离子促进剂十二烷基二甲苄基氯化铵进行对比,探究了促进剂和氢氧化钠用量、碱减量处理温度和时间等因素对涤纶减量率的影响,测试了碱减量处理前后涤纶的强力和形貌。结果表明:烷基咪唑类Gemini促进剂可用于涤纶纤维的碱减量加工,且相同结构的促进剂对涤纶纤维的促进作用符合Traube规则;促进剂疏水性越强,涤纶的减量率越高;促进剂的加入可降低氢氧化钠的用量,促进涤纶纤维的碱减量,且碱减量加工后涤纶表面形成凹槽,纤维变细,比表面积增大。In order to exploit new alkali deweighting accelerant and its application process for polyester fabrics to improve the efficiency of alkali deweigthing , three alkyl imidazolium Gemini ionic liquids were applied as accelerants for alkali deweighting of polyester fabrics, compared with conventional cationic surfactants 1227. The influences of the amount of ionic liquid and sodium hydroxide, temperature and time deweighting ratio of polyester were analyzed. The strength and morphology of polyester fabrics were also tested. The results show that the alkyl imidazolium Gemini ionic liquid can be used for alkali deweighting, and the effect of ionic liquid accelerant with the same structure on alkali deweighing follows the Traube rule. Gemini ionic liquid accelerant can reduce the consumption of sodium hydroxide, and promote the alkali deweighting of polyester fabric. Grooves appears on the surface of polyester, the fineness becomes small, and the specific surface area becomes larger after alkali deweighting.
