摘要
研究了湿度对介质阻挡放电等离子体处理涤纶织物性能的影响,以氩气和氧气分别为载气和反应气体,对涤纶织物进行常压介质阻挡放电处理,利用扫描电子显微镜和X光电子能谱仪分析等离子处理前后纤维表面形态和化学成分的变化,并利用水滴吸收时间表征织物吸湿性.结果表明,介质阻挡放电处理可以使涤纶织物表面的粗糙度增加,并且湿度大的织物处理后粗糙度更大.处理后,O/C比率增加,表明有新的含氧基团生成,而湿度大的O/C比率更高.刚刚处理完的试样,织物湿度对处理后的水滴吸收时间没有太大的影响,在织物洗后水滴吸收时间增加,但洗后放置一段时间后未见明显改变.大气条件下的时效性测试中,织物性能也未见明显改变.
In order to investigate how the existence of moisture affects dielectric barrier discharges (DBD) treatment, polyester fabrics were treated by argon and oxygen plasmas using DBD at different moisture conditions. The DBD treatment etched the surfaces and the roughness of the fabric surfaces was modified. It was shown that the surface roughness were higher for the wet group than that of other groups. After plasma treatment, the O/C ratios increased. This increase shows that new oxygen-containing groups were formed on the fabric surfaces, and the wet group had the higher O/C ratio. It was found that there was no significant effect on wettability gained immediately after treatment for different moisture conditions. In the aging testing, it was proved that the durable stability on surface was changed when the treated samples were placed in the ambient air. The wettability of DBD treated fabrics had no remarkable change after 2 weeks in ambient air.
