CHAPTER I

FIBERS

All the materials used in the manufacture of clothing are called
_textiles_ and are made of either long or short fibers. These fibers
can be made into a continuous thread. When two different sets of
threads are interlaced, the resulting product is called cloth.

The value of any fiber for textile purposes depends entirely upon the
possession of such qualities as firmness, length, curl, softness,
elasticity, etc., which adapt it for spinning. The number of fibers
that possess these qualities is small, and may be classified as
follows:

_Animal Fibers:_ Wool, Silk, Mohair.

_Vegetable Fibers:_ Cotton, Flax, Jute, Hemp, etc.

_Mineral Fibers:_ Asbestos, Tinsel, and other metallic fibers.

_Remanufactured Material:_ Noils, Mungo, Shoddy, Extract, and Flocks.

_Artificial Fibers:_ Spun Glass, Artificial Silk, and Slag Wool.
