Mohair is a silky white Wool fiber that from the Angora goat, a breed of domestic goat, Capra aegagrus hircus. The angora goat is native to Turkey and Mohair was produced solely in Turkey for thousands of years, only becoming important in European textile manufacture during the 19th century. Angora goats are generally sheared twice a year. Their hair is mainly composed of long (5 - 12 inch) fibers that have flat, barely visible, overlapping scales. This makes the fibers very smooth and shiny. Mohair is strong, resilient, durable, and has good affinity for dyestuffs. The wool also contains 18% short fibers called kemp. These fibers are coarser and do not dye well. Mohair is susceptible to moths, but otherwise very durable. It is used for suits, clothing, draperies, upholstery, carpets, paint brushes, and paint roller covers.
