[0002] The high symmetry of the molecular chain structure of polyester and the rigidity of the benzene ring give the products good mechanical processing properties, chemical corrosion resistance and anti-microbial erosion properties. Moreover, due to its relatively low price and easy recycling, it is widely used in various fields such as fibers, films, and plastic products.

[0003] With the rapid growth of the national economy and the general improvement of people's living standards, the requirements for the speed, safety, comfort and economy of transportation are getting higher and higher.
