摘　　要：研究了易染型海岛PTT纤维的碱处理工艺条件,即达到最佳碱处理效果的碱浓度、碱处理时间和碱处理温度以及双烷基二甲基氯化铵(812)的浓度。结果表明最佳工艺条件为:NaOH质量分数12%,浴比1∶50,碱处理温度90℃,时间60 min。加入协同剂能明显提高纤维的碱减量率,协同剂的最佳质量分数为0.7%。In this paper,the optimal process condition of alkaline chemical treatment for easy-dyeable sea-island polytrimethylene terephthalate（PTT） drawn yarn was discussed,including alkali concentration,treatment time and temperature as well as the concentration of Collaborative emulsifier,Dioctadecyl Dimethyl Ammonium Chloride（DODMAC 812）.Results showed that optimum alkaline chemical treatment process was set as followings;concentration of sodium hydroxide was 12%（w）,liquid ratio was 1∶ 50,temperature was 90 ℃,time was 60 min,and concentration of DOOMAC 812 was 0.7%（w）.
