2、ain production methods : PTA (direct esterification method) and DMT method (ester exchange method). The advantages of the direct esterification method are as following: the consumption of raw materials is low, the reacti

3、on time is too short, so on, the direct esterification method has become the main technology in the synthesis of semi dull polyester chips after 1980. Polyester chip PET as raw material is not only involved in the produc

4、tion of fiber, engineering plastics, film, plastic bottles, film, packaging materials, various types of plastic products, containers, and so on. In the present production, polyester chips (PET) are mainly made of polyest

5、er fiber. Made of polyester (PET) fiber has a brilliant luster and its strength and flexibility is better than ordinary wire, but a lot of silk does not necessarily require a strong brilliant luster, so some companies in

6、 the silk additive for extinction. The principle of the extinction process is in the production process to add the appropriate amount of extinction agent (commonly used is titanium dioxide powder), matting agent in the r
