Synthetic human hair wigs are made from a co-polymer of vinylchloride and acrylonitrile and is called: (a) Poly Vinyl Chloride (b) Cellulose (c) Poly Vinyl cyanide (d) Dynel

Understanding co-polymer chemistry is essential when delving into the world of synthetic materials. Co-polymers are formed when two or more different types of monomers are polymerized together to create a new material with unique properties. In the context of synthetic human hair wigs, a notable co-polymer involves vinyl chloride and acrylonitrile.

Vinyl chloride is a colorless gas used primarily to make polyvinyl chloride (PVC), known for its durability and used in numerous products. On the other hand, acrylonitrile is known for its ability to form fibers that are resistant to heat and chemicals. Combining these two monomers results in a material that harnesses the positive attributes of both, leading to improved tensile strength, resistance to chemicals, and the capacity to be dyed in various colors, which is particularly useful in the production of synthetic wigs.

The polymerization process of these monomers is initiated by catalysts and occurs under specific conditions that foster the linking of vinyl chloride and acrylonitrile units. The resulting co-polymer benefits from the plastic properties of PVC and the strong, resilient characteristics of the acrylonitrile fibers.

The demand for synthetic human hair wigs is driven by various factors, including cosmetic preference, medical conditions, and the arts industries. One of the most significant advantages of synthetic wigs is their affordability compared to natural human hair wigs.

Synthetic wigs are manufactured using specialized types of co-polymers that mimic the look and feel of natural hair. With the incorporation of vinyl chloride and acrylonitrile co-polymers, these wigs can offer users versatility in style and color. Synthetic wigs are generally easier to maintain than natural hair wigs, as the fiber used in them retains its shape after washing, requiring minimal styling.

The process of creating these wigs begins by spinning the co-polymer into fibers that can be woven into hair strands. Then, the fibers are treated and processed to achieve the desired softness, texture, and color, making them a highly customizable product for end-users.

Dynel is the trade name for a co-polymer composed of 60% vinyl chloride and 40% acrylonitrile. It has gained popularity in various applications, one of which is synthetic hair wigs. Dynel is valued for its similarity in appearance and feel to human hair, in addition to its resilience and ability to hold color.

Being resistant to heat and certain chemicals makes Dynel a practical choice for the tough conditions wigs may be subjected to, such as styling tools and environmental factors. It's worth noting that Dynel, like all synthetic fibers, does have its limitations, such as a lower resistance to high temperatures compared to some other synthetic fibers.

Choosing Dynel as a material for wigs balances the need for durability, ease of care, and aesthetic appeal. The development of Dynel and its use in synthetic wigs represents a significant achievement in material sciences, offering a high-quality option for those seeking the benefits of a synthetic option.
