Polymer materials are generally insulating material. Therefore, it is easy in the course of the accumulation of electrostatic charge. It will affect the people and impact the environmental when it is discharged. In order to reduce the electro-resistance of polymer materials, we need to add the antistatic functional powder into the polymer material. The polyester polymer is one of the common textile fiber materials; surface electro-resistance up to 10^(13)Ω/sq and it is easy to produce static electricity. In this study, anti-static functional powders had been added to reduce the surface electro-resistance of the polyester polymer. By the DSC and Rheology, the thermal properties and melt viscosity would be analyzed for polyester polymer materials in the fiber spinning process.
