subject: Synthetic Fiber Of Hair Extensions [print this page] Hair extensions such as hair weft are made from a range of human and synthetic fibers. Synthetic fibers include Kanekalon and Toyokalon, and can differ from brand to brand. Synthetic hair in general is far less expensive than human hair, and is available in a wide array of colors and textures, from natural to extraordinary. However when considering hair extensions you must keep in mind that synthetic hair is just that synthetic and can not withstand hot temperatures so straightening and curling the hair is not an option as it will singe.
Synthetic hair is made of a wide array of different synthetic fibers. Synthetic hair, just as human hair, comes in hair weft and single strands for braids. Synthetic hair does not last as long as human hair because it gets quickly damaged from the sun. The quality of hair varies greatly, and if well maintained, synthetic hair can last up to a year. It will never look as human hair, as it is stiff and not bouncy at all. Synthetic hair of hair extensions is much less expensive than human hair.
Heating appliances such as curling irons and straightening combs generally should never be used on synthetic hair weft. There are newer versions of synthetic hair from some brands that claim to allow styling with lower temperatures of heating appliances. Generally people should steer clear of such claims because the golden rule with synthetic hair is that heat is not an option. Synthetic hair of hair weft is better used for shorter wigs. Typically when the synthetic hair is shaped it's best not to change it, it is "What you see is what you get".Synthetic Fibers for hair extensions are made from synthesized polymers or small molecules. These materials of hair weft are polymerized into a long, linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers of hair extensions, they generally have the same common properties.
There are several methods of manufacturing synthetic fibers but the most common is the Melt-Spinning Process. It involves heating the fiber until it begins to melt, then you must draw out the melt with tweezers as quickly as possible. The next step would be to draw the molecules by aligning them in a parallel arrangement. This brings the fibers closer together and allows them to crystallize and orient. This utilizes heat to permeate the shape and dimensions of the fabrics made from heat-sensitive fibers for hair extensions.
