Anti-static charge character of the plasma treated polyester filter fabric

Polyester fabrics were subjected to low temperature plasma (LTP) exposure. The anti-static behaviours of the plasma treated fabric were greatly improved. The discharge power of 50 V and the electrode gap of 4 mm were recommended for an optimum result. Acrylic acid treatment further enhanced the anti-static properties of the specimens. Influences of the acid concentration, the treating duration and the temperate during the acrylic acid treatment on the anti-static properties of the fabric were revealed.
