The invention discloses a processing method of ceramic healthcare yarn. The method includes the steps that firstly, by weight, 90-95 parts of polyester fibers and 6-10 parts of ceramic powder are mixed and stirred to be uniform; then, the mixture is heated to 250-285 DEG C and extruded with a twin-screw extruder; then, the material extruded by the twin-screw extruder is squeezed out of spinneret orifices with a metering pump for spinning, and cellosilk is jetted into a cooling device for cooling; then, stretching treatment, low-temperature drying and high-temperature sintering are carried out in sequence, and the finished product ceramic healthcare yarn can be obtained. Toughness can be improved through the method, and the method further has the advantages that production cost is low, the healthcare effect is good, and sintering uniformity is good.
