Atmospheric pressure plasma processing can modify the surface of the fiber and create polar functional groups on the surface of the fiber. In this study, an experiment was conducted on the hydrophilization of the ultra-hydrophobicity of polypropylene through plasma processing and surface changes before and after plasma processing. The ultra-hydrophobicity of polypropylene is the cause of impossible for dyeing and imparting functionality. Untreated polypropylene became hydrophilic, and it was confirmed that the ratio of oxygen and carbon(O/C) increased about 11 times from untreated polypropylene 0.017 to plasma-treated polypropylene 0.190.
