A method of manufacturing a mixture PTFE thread using a mixture PTFE powder consisting of PTFE: 73-95 wt %, MoS2: 3-25 wt %, Al2O3: 1-5 wt %, and Al(OH)3: 1-5 wt % comprises heat-retaining step for adding 18-25 wt % kerosene of a solvent to the mixture PTFE powder and keeping it warm at 30-50° C. for 40 to 50 hours, extruding the heat-retained mixture PTFE powder into a rod shape with a circular or elliptical cross section at the cylinder temperature of 70-90° C., rolling the extrusion at 100-150° C. into a 0.3-0.7 mm thick sheet shape, multiple-folding the sheet and passing the sheet through an oven at 250-270° C. at the rate of 10-40 cm/s, and stretching the folded sheet with a stretch ratio of 200-600% in multiple stages after heating the sheet at 450-500° C.
