Mohair, animal-hair fibre obtained from the Angora goat and a significant so-called specialty hair fibre. The word mohair is derived from the Arabic mukhayyar (âgoatâs hair fabricâ), which became mockaire in medieval times. Mohair is one of the oldest textile fibres, produced exclusively in Turkey for thousands of years and achieving importance in European textile manufacture during the 19th century.
