Animal fibers are natural fibers that consist largely of particular proteins. Examples include silk, hair/fur (including wool) and feathers. The animal fibers used most commonly both in the manufacturing world as well as by the hand spinners are wool from domestic sheep and silk. Also very popular are alpaca fiber and mohair from Angora goats. Unusual fibers such as Angora wool from rabbits and Chiengora from dogs also exist, but are rarely used for mass production.
Not all animal fibers have the same properties, and even within a species the fiber is not consistent. Merino is a very soft, fine wool, while Cotswold is coarser, and yet both Merino and Cotswold are types of sheep. This comparison can be continued on the microscopic level, comparing the diameter and structure of the fiber. With animal fibers, and natural fibers in general, the individual fibers look different, whereas all synthetic fibers look the same. This provides an easy way to differentiate between natural and synthetic fibers under a microscope.
silk: is a "natural" protein fiber, some forms of which can be woven into textiles. The best-known type of silk is obtained from cocoons made by the larvae of the silkworm Bombyx mori reared in captivity. Rearing of silks is called sericulture. Degummed fibers from B. mori are 5-10 μm in diameter. The shimmering appearance for which silk is prized comes from the fibers' triangular prism-like cross-sectional structure which allows silk cloth to refract incoming light at different angles.
Spider silk is the strongest natural fiber known. The strongest dragline silk is five times stronger than steel and three times tougher than Kevlar. It is also highly elastic, the silk of the ogre-faced spider can be stretched six times its original length without damage. As of 2005, there is no synthetic material in production that can match spider silk, but it is actively being sought by the U.S. military for such applications as body armour, parachutes and rope.[1] Genetically engineered goats have been raised to produce spider silk in their milk at a cost of around $1,500 per gram.[2]
Wool is the fiber derived from the fur of animals of the Caprinae family, principally sheep, but the hair of certain species of other mammals such as goats, alpacas, and rabbits may also be called wool.
Alpaca Edit
Alpaca fiber is that of an alpaca. It is warmer than sheep .
Angora Edit
Angora wool or Angora fiber refers to the down coat produced by the Angora rabbit. There are many types of Angora rabbits - English, French, German and Giant. Angora is prized for its softness, thin fibers of around 12-16 micrometers for quality fiber, and what knitters refer to as a halo (fluffiness). The fiber felts very easily. Angora fiber comes in white, black, and various shades of brown.
Bison Edit

Bison fibers refer to the soft undercoat of the American Bison. The coat of the bison protects the animal during harsh winter conditions, and consists of a coarse shiny overcoat, a coarse bulky midcoat, and a short dense undercoat. The undercoat is composed of fine, hollow guard hairs (average diameter of 59 micrometers) and down (average 18.5 micrometers). Downy fibers are typically chosen for textile applications. Bison fibers are grey or red-brown and about 2.5 cm long.[3][4]
Cashmere Edit
Cashmere wool is wool obtained from the Cashmere goat. Cashmere is characterized by its luxuriously soft fibers, with high napability and loft. In order for a natural goat fiber to be considered Cashmere, it must be under 18.5 micrometers in diameter and be at least 3.175 centimeters long. It is noted as providing a natural light-weight insulation without bulk. Fibers are highly adaptable and are easily constructed into fine or thick yarns, and light to heavy-weight fabrics.
Mohair Edit
Mohair is a silk-like fabric or yarn made from the hair of the Angora goat. 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.
Sheep's wool Edit
Wool has two qualities that distinguish it from hair or fur: it has scales which overlap like shingles on a roof and it is crimped; in some fleeces the wool fibers have more than 20 bends per inch. Wool varies in diameter from below 17 micrometers to over 35 micrometers. The finer the wool, the softer it will be, while coarser grades are more durable and less prone to pilling.
Qiviut is the fine underwool of the muskox. Qiviut fibers are long (about 5 to 8 cm), fine (between 15 and 20 micrometers in diameter), and relatively smooth. It is approximately eight times warmer than sheep's wool and does not felt or shrink.
