According to the polyester yarn with the smooth and soft surface, through mutual cooperation of the structures such as the polyester wear-resisting layer, the cotton fiber layer and the hemp thread layer, the overall service life can be prolonged through the polyester yarn layer and the polyester wear-resisting layer, and then the heat retention property and the water absorption property are improved through the cotton fiber layer and the hemp thread layer, so that the overall using effect is better; through mutual cooperation of the conductive fiber layer, the carbon fiber layer, the silk layer, the modal fiber layer and other structures, static electricity can be eliminated through the conductive fiber layer, the human skin is protected through the carbon fiber layer, and the overall smoothness and softness are improved through the silk layer and the modal fiber layer, so that the device is higher in value and more convenient to use. And the practicability is better.
