[0002] Polyester fabric has high tenacity, good elasticity, good thermoplasticity, good wear resistance, good corrosion resistance and light resistance, and is widely used as a garment fabric. However, polyester fabric has low moisture absorption and poor conductivity, and static electricity is easily generated by friction. Static electricity makes the fabric prone to fuzzing and pilling, easy to stain, and adheres to the skin or other clothes, resulting in uncomfortable wearing, and also causes an instantaneous impact electric shock to the human body. In particular, static electricity is easily generated when the fabric contacts the skin in winter, which makes people feel uncomfortable. This is because the polyester fiber macromolecule is covalently bonded and cannot ionize or transfer electrons. In addition, the polarity is small, the hydrophobicity is large, and the charge is not easy to escape, so the charge is easily gathered. Therefore, it is necessary to increase the antistatic property of polyester fabric. SUMMARY
