摘要
综述了对位芳纶结构是影响其染色性能的原因,总结了近年来对位芳纶的染色方法和工艺。表明由于对位芳纶分子结构紧密,结晶度高,小分子染料很难进入到纤维大分子内部,而导致其染色困难,阻碍了对位芳纶在防护服等应用领域方面的进一步应用拓展。指出开展对对位芳纶染色理论的研究,对提高其染色性能及染品的色牢度有着重要的意义。
In this paper, the staining method of para-aramid fiber is briefly reviewed, the structure of para-aramid fiber is determined to evaluate the influence on dyeing performance. Para-aramid is difficult to be dyed due to its close molecular structure and high crystallinity, which hinders the para-aramid fiber＇s further application in the protective clothing area. The paper also point out that carrying out the research on the theory of para-aramid fiber dyeing has great significance in improving its dyeing ability and color fastness of dye product.
