Spinning is a manufacturing process for creating polymer fibers. It is a specialized form of extrusion that uses a spinneret to form multiple continuous filaments. [1] If the polymer is a thermoplastic then it can undergo melt spinning.

Spinning is manufacturing process for creating polymer fibers. It is a specialized form of extrusion that uses a spinneret to form multiple continuous filaments. There are four types of spinning for polymer; wet, dry, melt, and gel spinning.

Melt spinning is the simplest extrusion process in that no addition and subsequent removal of solvent is required. It is the most popular and economic method for polymer fiber manufacturing at industrial scales. In melt spinning, the fiber-forming substance is melted for extrusion through the spinneret and then directly solidified by cooling.

There are three main types of fiber spinning methods: melt, solution, and reaction spinning. In fiber spinning, a liquid polymer is extruded through small holes in a spinneret to form thin filaments, as shown below.

Man-made fibers are manufactured by spinning the polymer. There are three major types of spinning process. They are- Melt Spinning (It is used for polymers that can be melted easily.) Dry Spinning (It involves dissolving the polymer into a solution that can be evaporated.)
