【摘要】 芳砜纶是一种耐高温和阻燃的高性能合成纤维,已被用于防护制品、过滤材料、电绝缘材料、蜂窝结构材料以及阻燃产业用纺织品和家用纺织品。但是,芳砜纶纤维大分子有较高的结晶度、取向度和化学结构稳定,玻璃化温度高,并具有较强的疏水性,这些导致了染料难于进入纤维内部,染色困难。解决好芳砜纶的染色问题,将能更好满足芳砜纶纤维发展的商业颜色需求,并可拓宽其应用领域。本文以芳砜纶纤维为研究对象,主要探讨了阳离子染料载体法染色以及分散染料载体法染色,研究了载体种类、用量,无机盐种类、用量以及染色保温温度和时间对芳砜纶染色性能的影响。研究结果表明:在无载体的情况下,用阳离子染料和分散染料染色,芳砜纶颜色很淡;而采用阳离子染料和分散染料载体法染色,可将芳砜纶染至中色。阳离子染料载体法染色的总体效果明显好于分散染料载体法染色,分散染料载体法染色的耐洗和耐摩擦牢度均不够理想。阳离子染料苯乙酮载体法染色,染色效果佳,耐摩擦色牢度好,耐洗色牢度稍差,强力基本不变,但存在环保问题。用Levegal C45载体染色,总体效果最好。芳砜纶阳离子染料载体法染色的最佳工艺条件为:Levegal C45用量40 ml/L、氯化钠10g/L、染色温度130℃、时间30min。更多还原

【Abstract】 Polysulfonamide(PSA) is a new kind of high tempature resistance fiber . PSA has been applied in protective products, filtering materials, insulation products, flame retardant textile material and household textile material. However, PSA has high crystallinity, orientation, glass transition temperature, stable chem. Structure as well. In addition of fibre’s hydrophobic groups, dyes enter into the inner of fiber difficultly. If the question to the dyeing of PSA was resolved, it would satisfy the commercial demands of PSA’color and broaden its application field.In this paper, PSA was studied and dyed with cationic dyes and disperse dyes at the presence of carrier. The effects of different carriers and its quantity, kinds of inorganic salt and concentration, the dyeing time and tempature on dyeing proformance were discussed. By experiment, we obtained the conclusions as follows.The color of the polysulfonamide fiber was pastel shades under dyeing in the circumstance of no carrier. However, using the dieperse dyes and cationic dyes in the existence of carrier could make it moderate color.The experiment result showed dyeing with cationic carrier was better than disper carrier. The washing and rubbing fastness of fiber with disper carrier dyeing was unideal. Dyed with cationic dyes, the carrier hypnone was better and had good rubbing fastness, poor washing fastness, the strength was unchanged. But hypnone was unfriendly to the environment. So the carrier Levegal C45 was best in general.We attained the best dyeing parameters with cationic dyes in the existence of carrier. Those were: the concentration of Levegal C45 was 40ml/L, Nacl 10g/L, the temperature of dyeing was 130℃and the time is 30 minutes.更多还原
