Abstract:

This paper makes a comparative analysis of testing stability between AFIS and aQura. After testing card sliver produced by two different experiments (twelve plans in each experiment) with AFIS and aQura, the test results are analyzed with the theory of statistical analysis and the range and average of test times that can get a reliable test result of common test parameters of AFIS and aQura are calculated. The following conclusions are drawn that for the parameters of SCN number, SCN size and total neps number, the testing stability with aQura is much better than that with AFIS. For the parameters of nep mean size, 5% length, short fiber content by weight and short fiber content by number, there is no evident difference in test stability between aQura and AFIS, and test stability of them are all very high.
