Features: At the end of the 20th century, melt-spun polyurethane fibers began to emerge. Through the continuous efforts of polymer researchers and melt-spinning process researchers, the quality indicators of melt-spun polyurethane fibers have approached those of dry-spun products, replacing them in many fields. Since the production process of melt-spun polyurethane fibers is solvent-free, there are no environmental pollution issues. More importantly, melt-spun polyurethane fibers have a low initial modulus and exert less constraint on the human body, making them a "green" product suitable for producing elastic fabrics for underwear. This book introduces the raw material system and synthesis principles of the spinning polymers for melt-spun polyurethane fibers and their properties, with a focus on describing the spinning process, reaction principles, and characteristics of engineering equipment for melt-spun polyurethane fibers. It discusses the influence of the molecular structure, supramolecular structure, and morphological structure of polyurethane fibers on their performance, as well as the properties and applications of polyurethane fibers. The book also comprehensively introduces the post-processing technologies of polyurethane fibers, including processing, weaving, and dyeing. This book provides important reference materials for researchers, engineering technicians, and industry professionals in the fields of polyurethane fiber raw material production, fiber processing, weaving, and dyeing. It can also serve as a training textbook for technical personnel and workers, or a teaching reference for students and teachers in the field of synthetic fibers.
