摘要(Abstract)：

采用原液着色的方法,通过湿法纺丝制备了聚间苯二甲酰间苯二胺(PMIA)着色纤维,并对其进行了机械性能、染色深度、热失重、红外光谱分析测试。结果表明:原液着色PMIA纤维的机械性能受颜料加入量的影响很小;颜料含量为3%时就能赋予PMIA原液着色纤维较好的染色深度;原液着色PMIA纤维的起始分解温度较未着色PMIA纤维有所降低,但二者在失重率15%的温度及550℃的重量保持率相似,都具有较好的热稳定性。
In this paper,dope-dyed poly(m-phenylene isophthalamide)fibers with different pigment content were prepared by wet-spinning.The mechanical properties of the fibers were tested.Infrared spectroscopy,thermogravimetric analysis,sonic orientation were used to study the structure and properties of the fibers.The results showed that the addition of pigment had little effect on the structure and properties of poly(m-phenylene isophthalamide)fibers.
