* Modacrylic: This is a modified acrylic fiber. Acrylic is a polymer (a long chain of repeating molecules) made from acrylonitrile. Modacrylic fibers have acrylonitrile as their primary component, but also include other monomers (like vinyl chloride or vinylidene chloride) to improve their properties, such as flame resistance, crimp retention, and a softer feel.
* Kanekalon: This is a brand name of modacrylic fiber produced by the Japanese company Kaneka Corporation. It's widely considered a premium synthetic fiber for braiding hair because of its desirable qualities.
So, the simplified answer is:
* Ingredient: Primarily modacrylic polymer, specifically acrylonitrile, with other monomers (like vinyl chloride or vinylidene chloride).
* Brand Name: The most common brand name fiber is known as Kanekalon which is produced by Kaneka Corporation.
How it's made (Simplified Process):
While the exact details are proprietary to Kaneka Corporation, the general process of making modacrylic fiber involves the following steps:
1. Polymerization: Acrylonitrile and other monomers are chemically reacted together to form a large modacrylic polymer.
2. Dissolving: The polymer is dissolved in a solvent (a liquid that can dissolve other substances).
3. Spinning: The dissolved polymer is forced through tiny holes in a spinneret (a device similar to a showerhead) to create continuous filaments (strands). This process is called *dry spinning*, *wet spinning*, or *melt spinning*, depending on the solvent and how the fibers are solidified.
4. Solidification: The filaments are solidified. This can involve evaporating the solvent (dry spinning), washing the filaments in a liquid bath (wet spinning), or cooling the melted polymer (melt spinning).
5. Drawing: The solidified filaments are stretched (drawn) to align the polymer molecules, increasing the fiber's strength and flexibility.
6. Crimping/Texturing: The filaments are often crimped or textured to give them the desired look and feel of human hair. This is crucial for braiding hair to give it volume and prevent it from being too slippery. The X-Pression brand is known for its naturally tapered ends and soft texture, which results from specialized crimping and texturing techniques.
7. Cutting and Processing: The continuous filaments are cut to the desired length and further processed, such as by blending different colors, heat setting the crimp, and packaging.
Key Properties of Kanekalon X-Pression Hair:
* Lightweight: Doesn't weigh down braids or cause scalp tension.
* Soft Texture: Mimics the feel of human hair.
* Flame Retardant: A key safety feature.
* Tangle-Resistant: Easier to work with and reduces matting.
* Hot Water Set: Can be styled with hot water to seal ends.
* Variety of Colors: Available in a wide range of shades.
Essentially, Kanekalon X-Pression hair is a carefully engineered synthetic product designed to provide the look, feel, and performance characteristics desired for braiding and hair extensions, with safety as a paramount concern.
