摘　　要：通过选择合适的染料、纤维改性方法及染色方法,对芳纶1414纱线进行染色,探讨改性条件、染料种类和用量、染浴pH值、染色温度、染色时间等对染色性能的影响。结果表明,经碱改性的芳纶用分散染料染色的最佳工艺为:染料质量分数不超过5%(omf),染液pH值5,在130℃染色60 min;碱改性染色芳纶纱线的耐皂洗色牢度4～5级,耐升华色牢度与染料品种有较大关系。经酸改性的芳纶用阳离子染料染色的最佳工艺为:染料质量分数不超过5%(omf),染液pH值4～5,在120℃染色60 min;酸改性染色芳纶纱线的耐皂洗色牢度达到4～5级,耐升华色牢度达到4级。In this paper, proper dyes, modification methods and dyeing methods are selected to dye the aramid 1414 yarns. Factors exerting influence on dyeing behaviors are studied, such as modification conditions, types and dosages of dyes, pH value of dye bath, dyeing temperature and time. The optimum dyeing process of alkali-modifying aramid with disperse dyes is determined as follows ： the dosage of dyes less than 5 % （omf）, pH value 5, dyeing at 130 ℃ for 60 min. The color fastness to washing of the dyeings is up to grade 4 -5 and the color fastness to sublimation is dependent on dye properties. The optimum dyeing process of acid-modifying aramid with cationic dyes is determined as follows： the dosage of dyes less than 5 % （ omf）, pH value 4 - 5, dyeing at 120 ℃ for 60 min. The color fastness to soaping is up to grade 4 - 5 and the color fastness to sublimation is up to grade 4.
