Natural Fibers

In addition to wool and silk, a number of specialty fibers are also obtained from animals. In most cases, animal fibers are similar to each other. They grow in two principal coats: the shiny and stiff outer coat or hair; and the undergrowth or fur. Hair forms a protective shield around the animal's body against the elements; fur is closer to the skin and consists of shorter fibers than the hair that acts as insulation against heat or cold.

Fabrics containing specialty fibers are expensive because of the difficulties in obtaining the fibers, and the amount of processing required to prepare the fibers for use. Unlimited combinations of specialty fibers with wool are possible. Specialty fibers may be used to add softness or luster to fabrics. They also enhance the insulating properties of blended fabrics.
