    摘要: The PTFE real twist yarn of the present invention is a PTFE real twist yarn obtained by twisting a polytetrafluoroethylene (PTFE) multi-filament slit yarn. The yarn has a circular cross-section with a circularity in the range of 10/8 to 10/10, where the circularity is expressed by the ratio between the major axis width and the minor axis width, the average fineness of filaments is in the range of 1.5 to 200 dtex, a fineness D is in the range of 50 to 6000 dtex, and a twist coefficient K expressed by Formula (1) is in the range of 10000 to 35000: twist coefficient K=number of twists T×(the fineness D of the PTFE real twist yarn)1/2  (1) where the number of twists T denotes the number of twists per meter and the fineness D is a total fineness.
