Vinyon is a synthetic fiber made from polyvinyl chloride. In some countries other than the United States, vinyon fibers are referred to as polyvinyl chloride fibers. It can bind non-woven fibers and fabrics. It was invented in 1939.

It has the same health problems associated with chlorinated polymers. In the past, Vinyon was used a substitute for plant-based filters in tea bags.

Vinyon fiber characteristics

• doesn't flame, but softens at low temperatures(55 C)
• high resistance to chemicals
• Moisture absorption is less than 0.5% and moisture regained is less than 0.1%
• crease resistant and elastic

Major vinyon fiber uses

• industrial applications as a bonding agent for non-woven fabrics and products

Production

The U.S. Federal Trade Commission definition for vinyon fiber is "A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85 percent by weight of vinyl chloride units (—CH2—CHCl—)."

First U.S. commercial vinyon fiber production: 1939, FMC Corporation, Fiber Division (formerly American Viscose Corporation).
