| Abstract: | The preparation and post-treatment of thermotropic liquid-crystalline polyarylate(TLCP) fiber with low and high molecular weight were introduced.The deformation of TLCP melt at the bottom of spinneret during the spinning was analyzed.Fiber's mechanical properties and crystal properties after thermal treatment were studied with the help of scanning electron microscope,X-ray diffraction and fiber-strength instrument.These researches would be valuable for the commercial production of polyarylate fiber. |
| Keywords: | thermotropic liquid-crystalline polyarylate spinning process post-treatment mechanical property |
