ª¤ Regional Distribution of Cotton Fiber Quality in China Abstract£ºThe fibre quality status is very important for super quality cotton production and diverse requirements of textile industry in China.In this study,the quality of cotton fiber samples which are collected from 13 major cotton production provinces between 2001 and 2005 were analyzed. Eight quality traits including fiber length, uniformity index, specific strength, elongation, micronaire, reflectance degree, yellow degree, and spinning consistency index were tested. The data indicated that the cotton fiber length ranged around 28 to 29 mm, the fiber uniformity index ranged from 82% to 84%, fiber strength ranged from 27 to 29 cN¡¤tex-1, micronaire ranged from 4.0 to 5.0. These fibres could satisfy the requirements of middle and low grade spinning. The fibers from the Yangtze River Valley (Jiangxi, Hubei, and Hunan Province) were superer in length, strength, and uniformity index. However, the micronaire was a little higher, the color, character was not good enough, and,the grade was lower. The fiber qualities of the Northwest Inland Region (Xinjiang) were the best in terms of micronaire, color and grade. As for the Yellow River Valley Region, the index of its fibre qualities was between the above two regions.
