Enka is an unincorporated community in Buncombe County, North Carolina, United States. It lies on U.S. Routes 19, 23, and 74 Business near the interchange of Interstates 26, 40, and 240. Although it is unincorporated, it has a post office, with the ZIP code of 28728. The American Enka Company, incorporated in 1928, built what became the nation's largest rayon-producing factory. The Dutch name of the rayon company was Nederlandse Kunstzijdefabriek, and it is from the Dutch phonetic pronunciation of the initial letters N and K of the firm's name that "Enka" is derived. The alternative explanation that Enka stands for "Eerste Nederlandse Kunstzijdefabriek Arnhem" is incorrect. In 1929 the company began developing a community plan that included employee houses and became known as Enka Village.
