Abstract	Poly(m-phenylene isophthalamide) (PMIA) fibers play an irreplaceable role in the area of high-temperature resistance. It is usually difficult to dye PMIA fibers due to their rigid molecular structure and high crystallinity. In this study, the dope-dyed PMIA fibers with different amounts of pigment were fabricated by wet spinning. The properties of the pigment were analyzed, including size distribution and dispersive properties. The results showed that the pigment was easy to disperse in the fibers when the average diameter of the pigment was smaller than 500 nm. The color fastness of the colored PMIA fibers was tested, and their thermal properties and mechanical properties were also analyzed. The results of thermal gravity analysis (TGA) indicated that the colored PMIA fibers maintained good thermal performance. Compared to uncolored PMIA fibers, the colored PMIA fibers became lighter after exposing to simulated sunlight for 50 h. The breaking tenacity of fibers exceeded 2.0 cN/dtex, and the retentivity was above 80 % after being exposed to simulated sunlight for 50 h. These suggested the good mechanical performance of colored PMIA fibers. Dope-dyed PMIA fibers with good mechanical properties and thermal performance were successfully developed.
