animal fibre obtained from the Angora rabbit and the various species of the common rabbit. Rabbits have coats consisting of both long, protective guard hairs and a fine insulating undercoat.

The fibre of the Angora rabbit (so named for the resemblance of its pelt to that of the Angora goat) is produced mainly in France and England. A silky, delicate white fibre, it is prized for its fineness, soft texture, and lustre. The fibre is used mainly for high-quality woven fabrics, knitted goods, and knitting yarns. Angora rabbits are domesticated and are usually sheared, clipped, or plucked four times yearly, allowing each growth of fibre to reach about 8–9 cm (3–3.5 inches). Each animal yields about 200–400 g (7–14 ounces) of fibre annually.

Common rabbit hair includes that of domesticated white rabbits and the less desirable fibre of gray rabbits. These coarser grades of rabbit fur are an important source of felt and are obtained chiefly from rabbits produced in Europe, especially in France. Common rabbit hair is also used for knitted goods.

Both Angora and common rabbit fibre are often used in blends with other fibres to impart warmth and softness. Rabbit fur is also used in large quantities in the fur industry, though the pelts are fragile. The soft, delicate fur is plucked, trimmed, and dyed to simulate more valuable furs, such as seal and chinchilla.
