    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.

    摘要： A heating roller includes a cylindrical member and a winding. The cylindrical member has a cylindrical body forming first and second sides along an axial direction. Plural wiring holes penetrate the cylindrical body along the axial direction and are each open on the first and second sides. The winding has a conductive wire penetrating the wiring holes. The conductive wire extends in opposite directions through each two adjacent wiring holes and is connected to a power source. Alternatively, the heating roller includes two windings each having plural conductive wires penetrating the corresponding wiring holes, wherein the conductive wires of one of the windings are connected to the positive and negative terminals of the power source at the first and second sides respectively, whereas the conductive wires of the other winding are connected to the negative and positive terminals of the power source at the first and second sides respectively.
