First U.S. Commercial Vinal Fiber Production: (Vinal is not produced in the United States.)
Federal Trade Commission Definition for Vinal Fiber: A manufactured fiber in which the fiberforming substance is any long-chain synthetic polymer composed of at least 50% by weight of vinyl alcohol units, (-CH2CH[OH]-)X, and in which the total of the vinyl alcohol units and any one or more of the various acetal units is at least 85% by weight of the fiber. (Complete FTC Fiber Rules here.)
Characteristics and Vinal Fiber Uses Vinal fibers soften at low temperatures but have high resistance to chemicals. This makes them suitable for certain industrial uses. In some countries other than the United States, vinal fibers are referred to as polyvinyl alcohol fibers.
