利用氯磺酸、醋酸酐对芳纶短切纤维进行了改性处理，再用处理后的纤维配抄芳纶纸，探讨了处理工艺对芳纶纸力学性能的影响．结果表明，当氯磺酸浓度为2％，处理时间为10 m in ，处理温度为50℃时，芳纶纸的力学性能较好．用100％的醋酸酐对芳纶纤维进行处理然后配抄成纸，所得纸张的抗张指数和撕裂指数分别提高了63．8％和21．4％．另外，芳纶纤维经过醋酸酐浸泡1 min后再用甲醇处理3 min ，芳纶纸的抗张指数和撕裂指数分别提高了84．7％和38．4％．

The aramid short fiber was firstly modified with chlorine acid or acetic anhydride under different conditions respectively ,then mixed with fibrids to manufacture aramid paper and finally effect of different treatment process on the mechanical properties of aramid paper was discussed .Results show that aramid paper have better mechanical properties at the chlo-rine acid concentration of 2% ,processing time of 10min and processing temperature of 50 ℃ . T he tensile index and tear index aramid paper had increased 63 .8% and 21 .4% respectively when the fiber was modified by acetic anhydride at the concentration of 100% .In addition , tensile index and tear index of aramid paper had increased by 84 .7% and 38 .4% w hen the ar-amid fiber was soaked 1 min in acetic anhydride and treated 3 min in methanol .
