ResumoAbstract A critical review is presented of the development of orientation and crystallization in melt spinning. Methods of characterizing fiber structure are described. The development of molecular orientation in flow and approaches to the representation of crystallization in melt spinning processes are considered. Detailed critiques of the literature are given for the melt spinning of polystyrene, polyethylene, polypropylene, poly(vinylidene fluoride), poly(ethylene terephthalate), nylon‐6, and nylon‐66. Emphasis is given to the problems of spinline crystallization, polymorphism, orientation development, and crystalline morphology. The important role of spinline stress in determining structure development is emphasized. The influence of high speeds on melt spun fiber structure is described.
