Animal fibers

Jump to: navigation, search


Any fiber obtained from animal sources. Examples are wool, alpaca, mohair, angora, and silk. In general, animal fibers do not burn as readily as vegetable fibers. Instead, animal fibers 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 (cortex).

Synonyms and Related Terms
