Melt Spinning
(of fibers)

Overview

Melt spinning is the preferred method of manufacture for polymeric fibers. The polymer is melted and pumped through a spinneret (die) with numerous holes (one to thousands). The molten fibers are cooled, solidified, and collected on a take-up wheel. Stretching of the fibers in both the molten and solid states provides for orientation of the polymer chains along the fiber axis. Polymers such as poly(ethylene terephthalate) and nylon 6,6 are melt spun in high volumes.
