Diffuse plasma treatment of polyamide 66 fabric in atmospheric pressure air

- A cylindrical-electrode nanosecond-pulse diffuse-discharge reactor is presented.
- Large-scale non-thermal plasmas were generated steadily in atmospheric air.
- Treated PA66 fabric is etched with oxygen-containing group increases.
- The hydrophily of treated PA66 fabric improves effectively.
- Extending the treatment time is a method to reduce the treatment frequency.
