In this process, a polymer is melted and heated to a suitable viscosity for fiber production. The melted polymer is pushed through a spinneret, which is a type of die consisting of several small holes. Each hole produces an individual fiber, and the number of holes on a spinneret defines the number of fibers in the yarn. The melted polymer fibers then pass through a cooling region and the fibers are combined to form a yarn, and a spinfinish is applied. The yarn is then drawn using several godet rolls with very good speed and temperature control to orient the molecules in the fibers and eliminate voids, making the yarn stronger.
Melt spinning is the fastest fiber production system available in current technology. Therefore, if the polymer is thermoplastic, then melt spinning should be used for higher productivity. Most of the manmade fibers such as polyester, polypropylene, nylon, and PGA are produced using melt spinning.
Melt spinning technology is very advanced, and parameter control of the process is strong. It is possible to produce shaped fibers such as circular, triangular, and hollow fibers using melt spinning. Production of biocomponent and tricomponent fibers is also possible using this process.
