The utility model relates to polyester fabric with changing colors. The polyester fabric with changing colors comprises a polyester fabric layer formed by weaving warps and wefts, the warps are chinlon filaments, the wefts are multiple polyester semidull FDY filaments, the polyester fabric layer is coated with a nanometer layer and a polyurethane layer, the polyurethane layer is provided with a water permeable fabric layer and a water absorption layer, and the water absorption layer is internally provided with a macromolecule water absorbent. The polyester fabric with changing colors has the advantages that the polyester fabric layer is formed by weaving the warps and the multiple polyester semidull FDY filaments, wherein the warps are formed by the multiple sets of chinlon filaments which are arranged cyclically in an arithmetic progression mode, so that the surface of the polyester fabric layer forms a fine wave sense, colors change according to the color difference between the polyester semidull FDY filaments and the chinlon filaments, the sensitivity of colors is highlighted better through the nanometer layer, the iridescence effect is better, the practical performance is improved, water can be absorbed effectively through the water absorption layer, water permeable treatment is carried out on the water permeable fabric layer, and the waterproof performance and water permeable performance of the polyester fabric are improved effectively.
