Effect of atmospheric-pressure air/he plasma on the surface properties of ink-jet printing fabric was studied. Air/He plasma gave hydrophilicity on polyester surface and decreased contact angle to 18°. The roughness of polyester increased and pit-like structures appeared on the surface after plasma treatment. XPS confirmed the generation of new functional groups on polyester fabric. Relationship between wettability, fixation of pigments, anti-bleeding performance and color strength.
