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.

Physical and Chemical Properties

Good chemical resistance; Resistant to microorganisms and insects.
Attacked by formic acid, phenol, cresol and hydrogen peroxide
Fibers are smooth; Cross section = round, bean-shaped or u-shaped
Tenacity = 3.0 -8.5 g/denier (dry); 3.2-7.6 (wet)
Elongation = 9-26 (dry); 10-27 (wet)
Moisture regain = 3.0-9.0%.
Melting Point = 220-230 C
Density = 1.26-1.30g/ml

Risks

Nonflammable.
