Scope note
Any fiber obtained from animal sources, for example sheep wool, alpaca, mohair, angora, and silk. In general, animal fibers do not burn as readily as vegetable fibers, but instead tend to char and emit mildly nitrogenous odors characteristic of burnt hair. Except for silk, all animal fibers can be microscopically characterized by their tiny surface scales and center shaft.
