Impurities in different natural fibers:
The term impurity is used to described material other than fiber which is found in raw or processed stock. Generally, impurities must be removed during the spinning process, so the type and amount of impurity is also of importance to the yarn manufacturer.
Every natural textile fiber is made with a little bit of impurities which are totally unusable. Before use that fiber its need to remove those impurities from the fiber with keeps the useable part of that fiber. Various quantities of impurities and various types of impurities are included in textile natural fibers. Different types of natural fibers, impurities and quantities are given blew.
Impurities of Cotton Fiber:
Cotton is a uni-cellulose fiber. Cellulose is the use able and main part of the cotton fiber. 94% cellulose and 6% impurities are made a natural cotton fiber.
