[0049] Example 2: Measurement of the pulling smoothness of high-performance tubular woven fabrics at 20°C (normal temperature)
[0050] A method for measuring the smoothness of pulling out a top-entry tubular fabric, using the top-entry measuring device for the smoothness of pulling out a tubular fabric described in Example 1, the specific steps are:
[0051] ① Select a heat pipe with a head end corner radius r of 1 mm and a cavity inner diameter D of 15 mm; select fine denier PBO weakly twisted filament yarn as raw material, and design a high-performance tubular woven fabric with a diameter of 16 mm.
[0052] ② One end of the high-performance tubular woven fabric is sleeved on the outer wall of the temperature-controllable heat pipe 11, and the other end is placed between the clamp cover 21 and the plug tube 23 and clamped by the fastening screw 22.
[0053] ③ Start the heat pipe 11, and control the temperature of the wall of the heat pipe 11 to be 20° C. (normal temperature)...
