Abstract
The melt-spinning technique of fiber formation is the most popular polymer method for fiber conversion owing to the robustness of machine setup, high spinning speed at low cost, and absence of concomitant environmental issues. Various components of the melt-spinning line and their significance are discussed in detail in this chapter. A number of process parameters that affect the quality of the end product are indexed. The extruder is the primary part of the melt-spinning process. Both single- and double-screw extruders are covered comprehensively. Various types of metering pumps, spin packs, spinning manifolds, and spinnerets are adequately considered. Heat energy is employed to melt the fiber-forming polymeric material to an appropriate viscosity that is acceptable for melt polymer extrusion through spinneret orifices to get continuous filaments.
