In this paper are introduced the 4 times of changes of Uster statistic value since 1982, and analyzed the development trend of world yarn quality based on the changes. The problems that should be attentioned in the use of Uster statistic value are also pointed out. When in comparison of statistic value the testing conditions have to be same with a reasonable to lerance considered and a proper quality control level chosen to gain the best result.
