一种新的等离子体源及其在纺织材料表面改性中的应用

这里主要的工作就是采用并建立介质阻挡放电装置。在此基础上，使用空气和氩气两种工作气体进行等离子体放电，对等离子体放电电流和放电电压等参数进行较为系统的测量和诊断。由此找到适当的等离子体放电条件。这样，选择1mm宽的放电间隙，获得了较为理想且均匀的等离子体，并用其对大豆纤维进行表面改性。从扫描电镜等测试结果显示，改性后大豆纤维的表面性能有明显改善。

A New Plasma Source and Its Application in the Surface Modification of Fabric Materials

In this paper, a new dielectric barrier discharge equipment has been designed and established. We are concerned with the atmosphere pressure discharge plasma. Two different gases (air and argon) have been used for producing atmosphere pressure discharge plasma at different discharge gaps. Non-linear relationship between the discharge current and voltage at different discharge gaps is obtained. Two distinct plasma discharge features at different discharge conditions have also been observed. Based on the results above, the dielectric barrier discharge with a gap of 1 mm is used for producing a uniform plasma source. This plasma source has been used for modifying the surface of soybean fiber. Experimental results indicate that the performances of the treated fiber have obviously been improved.
