摘　　要：采用磷酸在超声下对聚对苯二甲酰对苯二胺(PPTA)纤维进行表面改性,并根据试验条件进行了正交试验设计。对处理后的样品进行了扫描电镜、接触角、单丝断裂强度测试。结果表明该方法能够在对纤维本身力学性能无明显损伤的情况下,有效地改善其表面润湿性。另外还对试验结果进行了统计分析,对最佳试验条件的选择进行了初探,并讨论了各个因素对试验结果影响的显著性大小。In this study, PPTA（poly（p-phenylene telephthalamide）） fiber was treated by phosphoric acid in an ultrasonic environment. An orthogonal test was also used in designing the experiment. The resulted fiber was analyzed by SEM, tensile strength and wrapping angle test. The data and results proved that this method could improve the wettabiltiy of the fiber without damaging the mechanical properties of the fiber. Meanwhile, an orthogonal test was used to find the optimal condition to improver the wettablity. The effect significance of every element was also studied.
