Melt spinning, which is the fiber formation process of PET, Nylon, PP etc., sometimes does not categorized as polymer processing, but analogous concepts of the melt spinning theory can be applied when analyzing some kinds of polymer processing too. Many Japanese researchers have been contributing to the melt spinning theory from many phases. Kase and Matsuo did pioneering works of melt spinning theory [1], [2], [3], and Hamana et al. [4], [5] refined the theory. They caved the way of applying the theory for practical uses. These theories were developed for steady-state single-filament spinning. In succession to these theories, many extended theories, e.g. steady-state multi-filament theory by Yasuda et al. [6], were published. In this chapter, steady-state single-filament theory for PET spinning by George [7], which is said to be applicable to a fairly wide range of spinning speed, is brought up and the theory, its simulation program and calculation example are described in detail. Furthermore, modified theory for PP spinning based on George's is mentioned. [1] Kase,S. & Matsuo,T., J. Polym.
