Ⅰ Ⅰ 改性聚芳噁二唑纤维及其混纺散纤维的染色性能研究 中文摘要 改性聚芳噁二唑纤维及其混纺散纤维的染色性能研究 中文摘要 改性聚芳噁二唑（POD）纤维兼具耐高温、阻燃、耐化学腐蚀、尺寸稳定等优异 性能，可广泛应用于特种服装、防护制品、过滤材料、电绝缘材料、摩擦材料等领域。 但是,目前对改性聚芳噁二唑纤维的研究主要集中在其可纺性能上，对其染色性能的 研究几乎处于空白，极大地限制了改性POD纤维的应用。因此，研究聚芳噁二唑纤维 及其混纺织物的染色性能是拓宽其应用前景的首要问题之一 。 本课题主要探讨了改性POD/PET混纺散纤维的染色工艺；研究了改性聚芳噁二唑 纤维的低温染色工艺，并与常规高温高压染色工艺进行织物性能对比；通过对染料的 筛选，确定了适合分散/活性一浴法染色的染料，探讨了中性电解质、碱剂对分散染 料低温染色的影响，以及染色助剂对活性染料染色的影响，确定了改性聚芳噁二唑/ 粘胶混纺散纤维一浴法染色工艺。 本研究结果表明：改性POD /PET混纺散纤维染色同色性最好的是分散蓝2BLN， 其次是分散红3B，最差的是分散黄H-3GL。以分散蓝为例，改性POD/PET混纺散纤维 的最佳工艺为：配比2:1（PET 1% owf），染色温度130℃，染色时间55min，pH值7。 染色后改性POD纤维的耐皂洗色牢度很好，但PET纤维的耐皂洗色牢度一般。 改性聚芳噁二唑纤维低温染色的最佳工艺为：染色助剂 2%-3%，温度 70℃，保 温时间 50min，pH 值 6-7。 改性 POD/粘胶混纺散纤维分散/活性一浴法染色工艺：纤维混纺比为 1:1 时，染 色助剂 0.5%，碱剂 15g/L，中性电解质 45g/L，染色温度 70℃。一浴法染色后的改性 POD 纤维和粘胶纤维的耐皂洗色牢度均较好，基本不沾色。 关键词：改性聚芳噁二唑（POD）纤维；染色；POD/PET混纺散纤维；POD/粘 胶混纺散纤维；分散染料；活性染料 作 者：张蓉蓉 指导老师：邢铁玲 Abstract Study on the dyeing of modified polyaromatic oxadiazoles fibers and its blend fibers Study on the dyeing of modified polyaromatic oxadiazoles fibers and its blend fibers Abstract Modified polyaromatic oxadiazoles (POD) fibers not only has high temperature resistance, flame retardant and resistance to chemical corrosion but has the dimension stability, etc. The fiber can be widely used in the special clothing, protection products, filter materials, electrical insulating materials, friction materials, and other fields. However, current research on modified POD fibers mainly foucsed on its spinning, dyeing performance research is nearly blank, which greatly limits the application of modified POD fiber. Therefore, study on the dyeing of modified POD fibers and its blend fabric is one of the most important issues of broadening its application prospect. In this work, dyeing process of modified POD/PET blend fibers was discussed. The low-temperature dyeing process of modified POD fibers was investigated and compared with conventional high temperature and pressure dyeing. By selection of dyes, suitable for one-bath dyeing method of dispe
