The properties of yarn are determined by the properties of fiber and the structure of yarn. Therefore, the quality of cotton fiber determines the quality of yarn to a certain extent. The length, fineness and maturity of cotton fiber, specific breaking strength, foreign and colored fibers, impurities and dense dew are the most important indexes to determine the quality of cotton yarn.
