Abstract

The invention belongs to the technical field of PET industrial yarns, and particularly relates to a preparation method of a PET industrial yarn for an automobile safety belt. The ZrO2 / carbon nanomaterial prepared through hydrothermal reaction has better dispersity in PET, and the uniformity and stability of the PET modified master batch are further improved. According to the invention, the ZrO2 / carbon nanomaterial is introduced into the PET modified master batch and is further blended, added and spun to prepare the PET industrial yarn for the automobile safety belt, so that the L value of the PET industrial yarn is reduced, the surface friction coefficient of the PET industrial yarn is remarkably reduced, the wear resistance of the PET industrial yarn is further greatly improved, the influence on mechanical properties is small, and the PET industrial yarn is suitable for industrial production. The service life is effectively prolonged. The PET industrial yarn developed by adopting a stock solution coloring technology does not need to be additionally added with a coloring agent, and is environment-friendly and pollution-free. The PET modified master batch prepared by the invention is uniformly dispersed in a PET tackifying slice, and the L value of the PET industrial yarn is basically free of deviation.
