摘　　要：为改善芳纶织物的表面黏结性能,采用常压氩气介质阻挡放电(DBD)等离子体处理对芳纶织物进行表面改性,研究处理时间对芳纶织物的表面形貌、表面化学成分、润湿性能、单纱断裂强力和剥离强度的影响规律。结果表明:DBD等离子体处理后,芳纶纤维的表面被刻蚀,粗糙程度明显增加;纤维表面氧、氮极性基团含量增加;纤维的表面润湿性和黏结性能均显著提高,且在处理时间为60 s时达到最优;等离子体处理对芳纶织物断裂强力的影响较小。Aramid fabric is modified by atmospheric argon dielectric barrier discharge （DBD） plasma treat- ment to improve the surface adhesion properties. The effect of treatment time on the surface morphology, surface chemical composition, wettability, single yarn strength and peeling strength of aramid fabric is studied. The results show that the surface roughness of the aramid fiber is enhanced significantly after DBD plasma treatment, and the contents of oxygen and nitrogen polar groups on the surface of the fiber are increased. When the treatment time is 60 s, the surface wettability and adhesive properties of the fiber are increased significantly, and the influence on the breaking strength is small.
