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.
