摘要
In this paper, an improved quasi-stable atmospheric pressure dielectric barrier discharge （DBD） plasma source is achieved after carefully controlled discharge voltage and current, discharge power, working gas, treatment period, and gap between the electrodes. This plasma source has been used to modify the surface of Polybutylene Terephthalate （PBT） melt-blown nonwovens and Polyester （PET） fabrics, and the various influences on surface modification and the aging effect of treated polymeric materials have been systematically investigated. In addition, the method of spectrum analysis is also used for diagnosing plasma paramneters such as electron temperature. Experimental results indicate that both the wettablity and permeation of treated PBT melt-blown nonwovens and dyeing ability of treated PET fabrics are certainly improved.
