Abstract Guided by the industrial policy, the shortcomings and development trend of China's polyester industry were discussed from four aspects: raw materials, engineering technology, application and environmental protection. The production technology of ordinary raw materials is fully developed, the industrial chain is complete, and the production technology of differentiated raw materials has a large gap with foreign countries. Polyester engineering technology has made great progress, but it needs to further improve flexibility, improve efficiency and reduce production costs. The catalytic technology is single and needs to develop in the direction of green and high efficiency. High-end polyester material processing equipment depends on imports. In chemical fiber, bottle piece, film, plastic and other application fields, the breakthrough of function and performance should be speed up, and the fierce homogenization competition should be avoided. The environmental problems caused by polyester materials are very serious. Recycling and degradability are important solutions.
