采用环氧丙基三甲基氯化铵对苎麻纱线进行阳离子改性.对未改性和阳离子改性的苎麻纱线使用活性橙5在液氨中于-35℃、浴比1:35、染色时间10~600 s、染料用量1%~100%(omf)进行染色.结果表明,未改性和改性的苎麻纱线在液氨染色中,染料的竭染率随染色时间的延长而增加,分别在60 s和180 s时趋于稳定,其对应的竭染率分别为24.3%和31.7%;最大竭染率在600 s,分别为26.5%和34.5%,阳离子改性提高染料竭染率约8%.在此染色条件下,活性橙5在未改性和改性苎麻纱线上的扩散系数分别为4.012×10-14和1.673×10-14 m2/s.液氨染色过程的动力学以准一级动力学模型和准二级动力学模型进行分析,结果表明,阳离子改性和未改性苎麻纱线的染色过程均符合准二级动力学模型.液氨染色过程的等温吸附模型运用Freundlich和Langmuir模型进行分析,结果表明,未改性苎麻纱线的染色吸附过程符合Freundlich等温吸附模型;而阳离子改性苎麻纱线的染色吸附过程符合Langmuir等温吸附模型.

Cationic ramie yarn was prepared with 2,3- epoxypropytrimethylammonium chloride agent. Sub-sequently, original and cationic modified ramie yarns were dyed with Reactive Orange 5 in liquid ammonia for dyeing time ranging from 10 s to 600 s with 1%~100%(omf) of dyeing concentration at- 35 ℃ and liquor ratio of 1:35. The results showed that the exhaustion percentages of both original and cationic ramie yarns were in-creased with the increase of dyeing time, and the adsorption reached a steady level at 60 s and 180 s, and the exhaustion percentage reached 24.3% and 31.7%, respectively. The highest exhaustion percentage of both ramie fibers were 26.5% and 34.5% at 600 s. The cationic modification increased the dye exhaustion per-centage about 8%. Under the special dyeing conditions, the diffusion coefficients of original ramie fiber and cationic ramie fiber were 4.012×10- 14 and 1.673×10- 14 m2/s , respectively. The dynamics of the liquid ammonia dyeing was analysed by the first- order kinetics model and second- order kinetics model. The dyeing process of the liquid ammonia dyeing of the both yarns fol owed the second- order kinetics model. The Langmuir andFreundlich models were applied to describe the experimental isotherms. The experimental data of untreated ra-mie yarn dyeing fitted the Freundlich model, but cationic ramie yarn fitted the Langmuir model.
