摘　　要：利用KMnO4在酸性的环境中具有氧化性的特性对芳纶纤维进行表面改性研究,分析其表面形貌、强力以及拉伸性能的变化;采用扫描电子显微镜观察处理前后芳纶纤维的表面形态特征;以夹角余弦幅度法确定权重;利用模糊正交法的理论与方法处理试验数据,得出模糊综合评价值.从而得出最佳实验指标为:硫酸质量分数10%,KMnO4质量浓度5 g/L,处理温度为30℃,处理时间35 min.The surfacial modification of aramid fiber was studied by using KMnO4′s strong oxidizing properties in strong acid,and its surface morphology,strengh and change of tensile properties were analyzed.The surface morpholo-gy characteristic of aramid fiber before and after the treatment is observed with scanning electron microscopy;the empowerment weight was fixed by the method of angle cosine,and the test data were processed by fuzzy the-ory and method;the fuzzy comprehensive evaluation values were concluded,then the optimum experimental in-dex was achievedt：he amout of sulfuric acid is 10%,mass percent concentration of KMnO4 is 5 g/L,treatment temperature is 30 ℃,processing time is 35 min.
