Man-made Fiber

A class name for various fibers (including filaments) synthetically produced from fiber-forming substances which usually refer to all chemically produced fibers to distinguish them from truly natural fibers such as cotton, wool, silk, flax, etc

Regenerated Fiber: The man-made fibers, derived from naturally occurring polymers are known as regenerated fibers. For instance rayon and acetate are made of the same cellulose polymers that make up cotton. In the case of rayon and acetate, the cellulose is acquired in an altered state usually from wood-Pulp operations.

Synthetic Fiber: Another group of man-made fibers is the synthetic fibers. Synthetic fibers are made of polymers that do not occur naturally. They are produced entirely in the chemical plant or laboratory, almost always from by-products of petroleum. Fibers produced from these polymers include nylon, polyesters, acrylics, the polyurethanes, etc.

Inorganic Fiber: The man-made fiber, derived from inorganic substance is called inorganic fiber. Glass, Carbon, Ceramic & Metal are the example of inorganic fiber.

Basic Characteristics: A synthetic polymer must have to have suitable characteristics with respect to several physical and chemical properties.

These are:

1.     A high softening point.

2.     Adequate tensile strength.

3.     Solubility or melting ability for spinning.

4.     A high modulus or stiffness.
