Abstract: The development status-quo and prospect of synthetic technology, fiber development and application of global polyester industry were introduced in this article. In the development of synthetic technologies, the 3 reactor process improve the polymerization capacity of single-line, and processes including 2R, MTR and CC-PET reduce synthesis steps and improve the process’s flexibility. Besides, all the above technologies further reduce the investment and energy consumption of polyester production. The recycling technology, direct spinning technology, nonwovens technology, liquid phase viscosity increasing technology and online modification technology improve the competitiveness of polyester fiber. Therefore, although the price of crude oil and regional economy are not so stable, polyester is still growing at a rate of 3% globally. Nowadays, most of the new production capacity of polyester focuses on bottles, film and engineering plastics. In the future, the traditional polyester industry should pay more attention on development of new upstream raw materials, new products, new technologies and new markets.
