摘　　要：采用自制介质阻挡放电连续处理装置,对涤纶和可染改性细旦丙纶进行表面改性处理,并测试经等离子体处理后试样的接触角、即时渗透性、毛效、衰减时间和K/S值,且用扫描电镜观察纤维表面变化。结果表明,经氩气常压低温等离子体处理的涤纶织物,表面性能得到了一定的改善;经氩气和氧气的混合气体常压低温等离子体处理的可染改性细旦丙纶织物,具有较强的染深效应,这可从电镜照片拍摄的纤维表面剧烈刻蚀加以证明。Surface modification of polyester and dyeable modified fine polypropylene were carried out by self-made dielectric barrier discharge （DBD） running in the environment （argon, argon/oxygen） at atmospheric pressure. Various properties such as contact angle, leakage current,wicking effect, decay time and K/S value were detected. It was found that DBD plasma can modify the surface of synthetic fibres. The wettability and the antistatic property of polyester in argon atmosphere were remarkedly increased. Plasma generated in the argon and oxygen mixed gas can impart polypropylene deeper dyeing, this can be confirmed by SEM photos as etching occurs on the surface.
