Polyester fabric with good heat insulation effect

The polyester fabric with the good heat insulation effect comprises a polyester fabric body, a first antibacterial layer is installed at the bottom end in the polyester fabric body, a second antibacterial layer is installed in the portion, above the first antibacterial layer, of the interior of the polyester fabric body, and the first antibacterial layer is evenly connected between the second antibacterial layer and the first antibacterial layer. An asbestos fiber layer is arranged in the polyester fabric main body above the second antibacterial layer, and heat conduction cavities are uniformly formed in the asbestos fiber layer. The asbestos fiber layer is arranged, the heat insulation performance of the asbestos fiber layer is excellent, heat can be effectively blocked, when the heat circulates in the polyester fabric body, the heat circulates in the multiple sets of heat conduction cavities, the section of each heat conduction cavity is in a Z shape, the circulation time of the heat can be effectively prol
