摘　　要：研究芳纶纤维NaOH处理对其成纸性能的影响。结果表明：用NaOH处理纤维使其表面被刻蚀并粗糙化,纤维表面极性基团增多,从而使纤维成纸的抗张强度和撕裂度均有所提升;最佳处理工艺为：NaOH溶液浓度为20%,处理温度40-45℃,处理时间20 min。Sodium hydrate was used in modification of aramid fiber. Aramid fiber was treated with different ways mixed with aramid pulp to manufacture aramid paper sheets. Modification of aramid fiber and its effect on aramid paper properties were studied. Results showed the best conditions are： concentration 20%, temperature 40-45℃, and time 20 min.
