Wet spinning is a fibre production method that involves extruding a polymer solution through a spinneret into a coagulation bath, where the solvent is removed and the fibre solidifies. Wet spinning is suitable for polymers that are not thermally stable or have high melting points, such as rayon, acrylic, aramid, and carbon fibre precursor.

Melt spinning is a fibre production process that involves melting a polymer and extruding it through a spinneret to form filaments. The filaments are then cooled and solidified by air or water. Melt spinning is used to produce synthetic fibres such as polyester, nylon and polypropylene.

Fibre production electro spinning is a process that uses electric fields to produce fine fibres from polymer solutions. The process involves applying a high voltage to a droplet of polymer solution, which forms a jet that is stretched and solidified by the electric field. The resulting fibres have diameters ranging from nanometres to micrometres and can be used for various applications such as tissue engineering, drug delivery, filtration and sensors.
