The high value-added functionality for synthetic fiber can be considered through a plasma enhanced treatment. In this study, PET(Polyethyleneterephthalate) was treated with a glow plasma and corona treatment. Surface characteristics of treated fabric were investigated using electron scanning microscopy(SEM), contact angle, X-ray photoelectron spectroscopy(XPS), tensile and adhesion strength. It was found that the contact angle showed $85.5^{circ}$ for untreated fabric, $0^{circ}$ for plasma and corona treatment at the condition of 200W for 7min. By XPS analysis, atomic ratio of O 1s/C 1s was increased from 0.27 to 0.43 by glow plasma and 0.27 to 0.41 by corona treatment at 200W for 7min, respectively. Glow plasma and corona treatment did not significantly change the tensile strength of PET fabric. Adhesion strength showed a substantial enhancement for the surface treated with the glow plasma, while corona treatment was adversely affected.
