The purpose of this study was to investigate a specific character on products of Korean cotton and American cotton with cultivated in sangju city, Korea. The results of this study were as follows: Productivity of American cotton was nine times higher than those of Korean cotton. Spinning coefficient index (SCI: 140), strength (32.6 g/tex), fiber length (1.12 inch), uniformity index (83.4%), short fiber index (6.4), color grade (21) of American cotton was superior than SCI (122), strength (27.7 g/tex), fiber length (1.02 inch), uniformity index(81.1 %), short fiber index (10.6), color grade (23) of Korean cotton. Microaire (3.5), elongation (6.9%) of Korean cotton was superior than American cotton.
