Relationship Between Polyester Quality and Processability Hands-on Experience

In particular, during the course of commercial polyester development it turned out that the use of highly purified raw materials is of paramount importance. In this respect the same principles apply to laboratory-scale chemical synthesis as those that apply to industrial-scale manufacturing. Polyester syntheses, like most

It is not the intention of this contribution to discuss phenomena that have already been expertly reported in the literature, but to create an insight into everyday polyester production that is a consequence of long years of industrial experience. For detailed mechanistic, chemical and analytical reports, readers may want to refer to a number of excellent reviews available in the literature. 

We will also attempt to link everyday experiences with fiber and film production to the industrial engineering measures taken to improve polymer quality. The similarities based on non-textbook knowledge are thus emphasized. In-depth considerations regarding special technologies would be beyond the scope of this present chapter. Therefore, the main focus is to present a modern state of knowledge regarding the relationship of polymer quality and the requirements of the processes. 

A major aspect of polymer, in particular polyester, production is the manufacturing of fibers for textile and technical applications. This section deals with the impact of the production conditions on the fiber quality. The following discussion will be mainly based on PET fibers, but by and large the problems, phenomena and their solutions are generally relevant to the production of other polymer filaments.
