Progress On Dyeing Technology of Meta-Aromatic Polyamide Fiber

In this paper, the structure and the dyeing properties of meta-aromatic polyamide fibers was described, and the recent development of dyeing technology of meta-aramid fibers was reviewed. The latest researches at home and abroad were introduced from three main aspects which included molecular structure, surface pretreatment and dyeing process. The surface modification methods are comprised of ultraviolet radiation, liquid ammonia, plasma, etc. And the improvement methods for the dyeing process contain vacuum decompression staining and carrier dyeing. In addition, the processing conditions and technologies of dope dyeing method for the colored metaaramid fibers produced were introduced in detail.
