摘　　要：采用2,3-环氧丙基三甲基氯化铵对苎麻纱线进行阳离子改性。然后,用活性艳蓝KN-R在液氨介质中对未改性苎麻纱线和阳离子改性苎麻纱线进行染色,探讨并分析了染色时间、染料用量对竭染率、固色效率以及单位质量吸附量的影响。结果表明,活性艳蓝KN-R在液氨中对苎麻纱线进行染色时,竭染率随着染色时间的延长而上升,随着染料用量的增加而下降,但苎麻纱线单位质量所吸附染料量呈直线上升;未改性苎麻纱线比阳离子改性苎麻纱线提前到达吸附平衡,阳离子改性后苎麻纱线竭染率、固色效率和耐水洗色牢度提高,但耐摩擦色牢度降低。Ramie yarn was modified by 2,3-epoxypropytrimethylammonium chloride. Unmodified and cationic modified ramie yarns were dyed in liquid ammonia with reactive brilliant blue KN-R, the effects of dyeing time and the dosage of dyes on exhaustion rate, dyeing fixing percentage and absorption per unit mass were discussed and analyzed. The results show that exhaustion rate increases with dyeing time, declines with the dosage of dyes, but dyes absorption per unit mass increases linearly; unmodified ramie yarn can reach adsorption equilibrium in advance when compared with cationic modified ramie yam; exhaustion rate, dyeing fixing percentage and fastness to washing of ramie yam modified by cationic modifier increases, but fastness to rubbing declines.
