Background

Spinning, also known as chemical fiber forming, is a process for manufacturing chemical fibers. The process of forming chemical fiber by making some high molecular compound into colloidal solution or melting into melt and extruding from fine holes of spinneret. The spinning colloidal solution or melt is delivered to the spinneret by a metering pump. The forming method mainly comprises two main types of solution spinning and melt spinning. The main varieties of synthetic fibers, such as terylene, chinlon, polypropylene, and the like, are produced by melt spinning.

The melt spinning is that the high molecular polymer is heated and melted into spinning melt with certain viscosity, the spinning melt is continuously and uniformly extruded to a spinning nozzle by a spinning pump, and the spinning melt is extruded into filament flow through fine holes of the spinning nozzle, and then the filament flow is cooled and solidified in air or water and is drawn into filaments. The melt spinning has the main characteristics of high winding speed, no need of solvent and precipitant, simple equipment and short process flow. Fiber-forming polymers that have a melting point below the decomposition temperature and are meltable to form a thermally stable melt can be formed by this method.
