Cotton is one of the most washable, wearable and durable of all fabrics. Advances in the technology of cotton cloth production provide us with more uses for cotton than for any other natural fiber. Cotton fiber comes in various grades based on color, purity, and ginning preparation. It is also classified in terms of fiber or staple length. Staple length determines the smoothness of the yarns that can be spun from cotton. Longer staple length produces a finished cloth that is soft and silky.
