Fiber quality of Indian cotton and American cotton was discussed. Six fiber quality indexes of the two kinds fiber were contrasted and analyzed, including upper half mean length, fiber uniformity index, micronaire, reflectivity, breaking tenacity and spinning consistency index. The result shows that length and breaking tenacity of Indian cotton are better than American cotton. Fiber uniformity index of the two kinds fiber is upper-middle. A grade and B grade of American cotton micronaire is higher than Indian cotton in total proportion. In reflectivity, the American cotton is the same, the distribution of Indian cotton is wider. In spinning consistency index, the Indian cotton is wider and higher than American cotton,so Indian cotton is more suitable to textile industry needs.%探讨进口印度棉与美棉的纤维品质.通过对比分析进口印度棉和美棉的上半部平均长度、纤维整齐度指数、马克隆值、反射率、断裂比强度、纺纱均匀指数等6项纤维品质指标,结果表明:印度棉的长度和断裂比强度要远好于美棉；印度棉和美棉的纤维整齐度指数均属于中等偏上；美棉马克隆值A、B两级总比例高于印度棉；反射率方面,美棉较一致,印度棉分布范围较广；印度棉的纺纱均匀指数较美棉分布广而且高,更能满足纺织业对棉花品质多层次的用棉需求.
