What is "Melt-spinning" - Definition & Explanation

Some polymeric fibres are spun by melting the polymer to a liquid state. The liquid is forced through the spinner opening under pressure and cooled by a jet of air to form the filament. Nylon can be spun by melting nylon polymer chips in a melt-extruder, a long heated cylinder that contains a rotating screw. The chips are melted as they travel the length of the heated zone of the tube, pumped to the spinerettes, and extruded into a cold air stream. Melt spinning requires no chemical reactions and no solvent recovery system, but is difficult to do because you need an exact temperature.
