Polyvinyl chloride fiber, 200x polarized light

A generic name for a manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of vinyl chloride units (Federal Trade Commission definition). Originally, Vinyon was a trademark of Union Carbide for polyvinyl chloride fibers copolymerized with Acrylonitrile called Vinyon N. Soon other variations of PVC polymers and copolymers called Vinyon were developed. By the 1950s, FTC adopted the name vinyon as a general term for PVC fibers. Vinyon fibers have good resistance to chemicals, bacteria, and insects. They soften at low temperatures and are often used to bond other fibers into nonwoven fabrics and to make heat sealable paper. They are used as flame-resistant fibers in children's clothing, blankets, draperies, and carpeting. Vinyon fibers are also used in fishing nets, twines, felts, and industrial fabrics such as tarps, awnings, and outdoor furniture.
