ANSYS finite element simulation software was used to simulate the heating process of silver coated yarns in fabric. The thermal filed distribution of heating fabric in different condition was analyzed by adjusting the distance between the silver coated yarns and output voltage. The heating fabric was prepared by the results of finite element simulation. The electrical heating property of heating fabric was researched and contrast with the results of finite element simulation. The result shows that, the equilibrium temperature of silver coated yarns rise with the increase of output voltage. The temperature is 109.7℃ by the output voltage is 7V. The distance of silver coated yarn in fabric is 3mm, which makes the surface temperature of heating uniform while the cost of silver coated yarns is lower. The equilibrium temperature and the heating speed rise with the increase of power density. The results of simulation are consistent with the actual results and the deviation is less than 4.5%. The results of finite element simulation can be important reference to guide the fabrication of heating fabric based on silver coated yarns.
