Wet spinning is the oldest of the five processes. This process is used for polymers that need to be dissolved in a solvent to be spun. The spinneret is submerged in a chemical bath that causes the fiber to precipitate, and then solidify, as it emerges.
The process gets its name from this “wet” bath. Acrylic, rayon, aramid, modacrylic, and spandex are produced via this process.
