Description
A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 50% by weight of vinyl alcohol units 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 (Federal Trade Commission definition). Polyvinyl alcohol (PVOH) was first made in Germany in 1924 and, in 1931 it was sold as Synthofil, a water-soluble fiber. In 1939, a formaldehyde treatment process was developed to make the vinal fibers insoluble. The fibers are very flexible, durable and have a high tensile strength. Most commercially available vinal fibers are made in Japan. Vinal is used primarily for raincoats, jackets, umbrellas, tarpaulins, fishnets, and awnings.
