Mohair usually refers to a silk-like fabric or yarn mae from the hair of the Angora goat. The word "mohair" was adopted into English before 1570 from the Arabic mukhayyar, a type of haircloth, literally 'choice', from khayyara, 'he chose'. Mohair fiber is approximately 25-45µ in diameter. It is one of the oldest textile fibers in use. It is both durable and resilient. It is notable for its high luster and sheen, and is often used in fiber blends to add these qualities to a textile. Mohair also takes dye exceptionally well. Mohair is also warm as it has great insulating properties. It is durable, moisture-wicking, stretch and flame resistant, and crease resistant.
