摘　　要：为提高腈纶纤维的匀染性能,利用阳离子表面活性剂的特殊结构,比较不同阳离子表面活性剂对腈纶纤维匀染性能的影响。研究二溴化N,N-二(十四烷基二甲基)-3-氧杂-1,5-戊二铵作为阳离子染料的染色助剂对腈纶纤维的匀染性能。结果发现经该双季铵盐表面活性剂处理后,腈纶纤维的匀染性能优于传统阳离子表面活性剂1227和1631处理的试样,当其浓度在1.5×10-5～2×10-5mol/L范围时,匀染性较好。这3种匀染剂对K/S值的影响排序为双季铵盐>匀染剂1631>匀染剂1227,对腈纶纤维染色匀染性影响的排序也为双季铵盐>匀染剂1631>匀染剂1227。Different cationic surfactants with special structure were used as additives in order to improve the level-dyeing property of the acrylic fiber.The level-dyeing property of N,N-bis（dimethyl tetradecyl）-3-oxa-1,5-penta diammonium bromide was used as dyeing additive for cationic dyestuff on the acrylic fiber.The results show that the level-dyeing property of bis-quaternary ammonium salt was better than that of traditional cationic surfactant 1227 or 1631 on acrylic fiber.Moreover,the level-dyeing property of bis-quaternary ammonium salt was the optimum when the concentration was from 1.5×10^-5 to 2×10^-5mol/L.The influence of these levelling agents on K/S value was as follows：bis-quaternary ammonium salt levelling agent 1631 levelling agent 1227,and so with the order in terms of level-dyeing property for acrylic fiber.
