Vinyon Fiber: History, Properties, Advantages and Disadvantages

What is Vinyon fiber?

Vinyon is a synthetic fiber used in textiles, known for being strong and versatile. It’s often used instead of natural fibers like wool or cotton. Vinyon fibers, made from vinyl chloride, are commonly called “Vinyon” or “Vinylon.”

History of Vinyon fiber

Vinyon was a Union Carbide trademark for special polyvinyl chloride fibers mixed with Acrylonitrile, and this was called Vinyon N. Afterward, different types of PVC polymers and copolymers, also named Vinyon, were introduced. In the 1950s, the Federal Trade Commission (FTC) started using the term “vinyon” to generally describe PVC fibers.

Properties of Vinyon

Vinyon dissolves in chlorinated hydrocarbons and aromatic solvents but doesn’t dissolve in water, alcohols, concentrated acids, and alkalis. When it burns, vinyon gives off a green flame and releases HCl. The cross-section looks irregular, like polygons, circles, or dogbones. The strength ranges from 0.7 to 3.0 g/denier, and it can stretch from 12% to 125%. Unfortunately, there’s no information about moisture regain. It softens at a Melting Point of 52°C, and the Density can vary between 1.38-1.43 g/ml.

Advantages of Vinyon

High chemical resistance.
High-water resistance.
Do not burn.
Their easy dissolution in numerous organic solvents restricts their potential applications.
PVC-Rhovyl is the market name for pure polyvinyl, whereas vinyon HH is a copolymer.

Disadvantages of Vinyon

Vinyon will melt in low temperatures.
