介绍射频辉光放电等离子体改善苎麻织物毛细效应的时效性的实验。分别在充入氩气、氮气、氧气的真空室中对苎麻织物进行射频辉光放电等离子体处理，在每一种处理过程中分别改变其处理时间、放电功率和真空室压强。测试了放置不同时间的经不同等离子体参数处理后的苎麻织物的毛细效应，得出各种参数的等离子体处理对苎麻织物毛细效应时效性的影响。实验结果表明，苎麻织物被等离子体离子体处理后毛细效应得到明显改善，其毛细效应随放置时间的变化为先快速下降，然后变缓，逐渐趋于稳定，这种毛细效应的改善具有良好的时效性，其中100W、40Pa的氧等离子体处理20分钟后的苎麻织物的毛细效应时效性最好。

Time effectiveness of capillary effect improvement of ramie fabrics processed by RF glow discharging

The time effectiveness of capillary effect improvement of ramie fabrics processed by RF glow discharging was studied. The ramie fabrics were processed in fulfilling with different gas (O2, N2, Ar) by different parameters (such as pressure, power and time) plasma. The capillary effect of the ramie fabrics processed by RF glow discharging was tested at different time. The results indicate that the capillary effect of ramie fabrics processed by RF glow discharging has been improved, the improvement of the capillary effect firstly decrease rapidly, then slowly, and become stable after 15 day, it indicate that improvement of the ramie fabrics capillary has good time effectiveness, and the plasma parameter for the best capillary effect improvement of ramie fabric is 100W and 40Pa processed 20mins by oxygen plasma.
