What is melt spinning?
Melt spinning is a manufacturing process used to produce continuous fibers or filaments from a variety of synthetic and natural polymers. In this process, a solid material is heated until it becomes molten and then extruded through a small orifice called a spinneret, which has multiple holes.
The extruded material is then quickly cooled, typically by passing it through a water or air quench, which solidifies the material into a continuous fiber. The resulting fiber can then be wound onto a spool or further processed into textiles, nonwovens, or other materials.
Melt spinning is widely used in the production of synthetic fibers such as polyester, nylon, and polypropylene, which are used in a wide range of products including clothing, carpets, and industrial materials. The process is also used to produce natural fibers such as silk and rayon.
