The Effect of Drawing Process on the Properties of Split-Film PTFE Fiber

Abstract:

From PTFE baseband prepared by three-dimensional drawing, after the processing of different temperature and time. And then by twisting, hot drawing and heat setting, the PTFE filament was prepared in appropriate tension conditions. The surface morphology of the resulting filaments was observed by SEM, the result shows that the uniformity of the PTFE membrane has been improved by using three-dimensional drawing process, hot drawing processes had a great effect upon the breaking strength and elongation at break of PTFE fibers. In order to keep ensure reasonable mechanical properties, the draw ratio in the range of 20 to 50 times to adjust the temperature controlled at 150°C to 300 °C.
