The aim for the progress of fiber spinning technology is to analyze the phenomena occurring in the industrial fiber-producing processes and seek the way to produce fibers which would fulfill the required properties. Fiber formation behavior needs to be investigated through two different approaches, i.e., theoretical analysis of the spin-line dynamics and in situ measurement of the spin-line. Regarding theoretical analysis, after the introduction of the fundamentals of spinline dynamics, various approaches for analyzing the spin-line behavior including the melt spinning of noncircular cross-section fibers, non-steady-state spinning, higher-order structure development, and the control of the state of molecular entanglement are discussed. Regarding the in situ measurement, analyses on the structure development behavior in the spin-line through the measurements of molecular orientation and crystallization are emphasized. In addition, detailed necklike deformation behavior occurring in the high-speed melt spinning process is discussed. Lastly, recent development of various distinctive fiber spinning technologies such as the utilization of low-temperature extrusion, mimicking of the bio-spinning process applying microchip technology, fabrication of fibers with various cross-sectional configurations, and structure control through multicomponent melt spinning process are introduced.
