synthetic hair manufacturing process

Synthetic hair is made from various types of synthetic fibers, commonly using materials like kanekalon, toyokalon, or other specialized fibers. The manufacturing process involves several steps, which I’ll outline below:

1. Polymerization: The first step is to create the raw material for synthetic hair, which involves polymerization. Polymerization is the process of combining small molecules (monomers) to form long chains of polymers. In this case, the polymer used is typically acrylonitrile, but other polymers may also be used.
2. Extrusion: Once the polymerization process is complete, the polymer is extruded through a spinneret. A spinneret is a metal plate with very fine holes through which the molten polymer is forced. As the polymer passes through the spinneret, it forms long, continuous filaments, much like strands of hair.
3. Cooling: The newly formed filaments are then rapidly cooled to solidify them. This can be done through various methods, such as air cooling or water cooling.
4. Drawing: After cooling, the filaments are stretched or drawn to align the polymer molecules and increase the strength and elasticity of the fibers. This drawing process is similar to pulling taffy and helps improve the overall quality of the synthetic hair.
5. Texturizing: Depending on the desired final product, the hair may undergo a texturizing process. Texturizing alters the surface of the fibers to give them a more natural look and feel. This can involve crimping, curling, or other treatments to mimic the texture of real human hair.
6. Coloring: The synthetic hair is often dyed during the manufacturing process. Various dyes and pigments are applied to achieve different colors and shades.
7. Cutting and Bundling: Once the synthetic hair filaments are processed and colored, they are cut to the desired length. The cut hair may then be bundled together to create hair wefts or other hair products.
8. Styling and Packaging: The synthetic hair can be styled into various shapes, such as straight, wavy, or curly. After styling, the hair is packaged for sale, either as individual bundles, wigs, extensions, or other hair products.

It’s important to note that the specific manufacturing process can vary depending on the type of synthetic fiber used and the intended application of the synthetic hair product. Some manufacturers may also incorporate additional steps or proprietary techniques to achieve specific characteristics or qualities in their synthetic hair products.
