Angora hair or Angora fiber refers to the downy coat produced by the Angora rabbit. While their names are similar, Angora fiber is distinct from mohair, which comes from the Angora goat. Angora fiber is also distinct from cashmere, which comes from the cashmere goat. Angora is known for its softness, thin fibers, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core of the angora fibre. It also gives them their characteristic floating feel. Yarns of 100% angora are typically used as accents. They have the most halo and warmth, but can felt very easily through abrasion and humidity and can be excessively warm in a finished garment. The fiber is normally blended with wool to give the yarn elasticity, as Angora fiber is not naturally elastic. The blend decreases the softness and halo as well as the price of the finished object. Commercial knitting yarns typically use 30–50% angora, in order to produce some halo, warmth, and softness without the side effects of excessive felting.
