常压介质阻挡放电对涤纶春亚纺织物的表面改性

采用常压介质阻挡放电技术对涤纶春亚纺织物进行表面改性，探讨不同放电功率、放电时间下织物润湿性能的变化。使用衰减全反射红外光谱法和X射线光电子能谱技术研究织物表面改性后化学组成及元素含量的变化，利用原子力显微镜表征改性后织物表面形貌的变化，并分析改性后织物的拉伸性能和透湿量。结果表明：常压介质阻挡放电改性可以极大地提高涤纶春亚纺织物的润湿性能，这源于织物表面氧元素的含量增加及表面粗糙化；改性后织物的断裂强力和断裂伸长率有所增加，透湿量也得到明显改善。

Surface modification of polyester pongee fabric by atmospheric pressure dielectric barrier discharge techniques

Polyester pongee fabric was modified by atmospheric pressure dielectric barrier discharge technology, and the influence of dischage power and discharge duration on the wettability of the fabric was discussed. Attenuated total reflection infrared spectroscopy and X-ray photoelectron spectroscopy were used to study the surface chemical composition and element content of the fabric. The atomic force microscopy (AFM) was employed to observe the surface morphology changes of the modified fabric. The tensile properties and water vapor permeability of the fabric was analyzed. The results showed that atmospheric pressure dielectric barrier discharge could greatly improve the wetting properties of fabric, due to the increased oxygen content and the surface roughness. At the same time, the breaking strength, elongation at break and water vapor permeability were also significantly improved by modification.
