Background
For centuries humankind has relied upon various plants and animals to provide the raw materials for fabrics and clothing.
Silkworms, sheep, beaver, buffalo deer, and even palm leaves are just some of the natural resources that have been used to meet these needs.
However, in the last century scientists have turned to chemistry and technology to create and enhance many of the fabrics we now take for granted.
There are two main categories of man-made fibers: those that are made from natural products (cellulosic fibers) and those that are synthesized solely from chemical compounds (noncellulosic polymer fibers).
Rayon is a natural-based material that is made from the cellulose of wood pulp or cotton.
This natural base gives it many of the characteristics—low cost, diversity, and comfort—that have led to its popularity and success.
Today, rayon is considered to be one of the most versatile and economical man-made fibers available. It has been called "the laboratory's first gift to the loom."
In the 1860s the French silk industry was being threatened by a disease affecting the Crepe Fabric silkworm.
