Description
A manufactured fiber containing at least 85% by weight of a long chain polymer of vinylidene dinitrile (-CH2-C(CN)2-) and having the vinylidene dinitrile group in no less than every other unit in the polymer chain (Federal Trade Commission definition). Nytril fibers were first sold commercially in 1955 under the brand name of Darlan. This name was soon changed to Darvan, but its production in the U.S. stopped in the early 1960s. Nytril made a soft, resilient fabric that did not shrink and was wrinkle resistant. It was used for sweaters and pile fabrics. Nytril was also used in wool blends to improve dimensional stability in coats and suits. The fibers, however, were difficult to dye and never became popular.
