摘　　要：对位芳纶纤维是一种高科技合成纤维,广泛地被应用于军事、商业、农业等领域,是现代人们生活工作之中不可或缺的材料,但是在我国研究起步较晚,生产技术较差,因此研究对位芳纶纤维具有重要的意义。本文介绍了对位芳纶纤维在国外和国内的研究发展历史,揭示了国内技术较差,但进步很快的事实,详细阐述了对位芳纶纤维的分子结构和表观结构,具体说明了短切纤维、浆粕纤维这两种不同形态芳纶纤维的的制备技术,进而充分展示了芳纶纤维密度小、强度高、模量大、耐腐蚀、耐磨损、热稳定性好、电导率低的特异性能,最后简述了芳纶纤维的基本用途,说明了对位芳纶纤维的应用前景广阔。Para-aramid fiber is a kind of high-tech synthetic fiber which is applied to military, commer- cial, agriculture and other fields, the material can not be obtained in the work of modern people＇s lives, but in our country, the research started too late and production technology is poor, so the research is great significance. This paper described the development of the para-aramid fiber in the domestic and o- verseas,and revealed the facts that domestic technology is poor, but progress is fast, in addition,this pa- per elaborated on the molecular structure and apparent structure of aramid fiber, and then chopped fiber and pulp fibers＇s preparation technology, and thus demonstrated fully the stability of para-aramid fiber, like as high strength, modulus, corrosion resistance, wear resistance, good thermal, the low conductivi- ty, in the end,this paper introduced briefly the basic use of aramid fiber, and given full recognition in our country＇s future development prospects of aramid fibers.
