Application of principal component analysis for test data of linen yarns with Uster

The test data of linen yarns with Uster was analyzed by principal component analysis method and compared with the test data by the seriplane.A comprehensive evaluation function was developed.It was shown that it is suitable for qualitative or quantitative evaluation of yarns,and its test result is in good agreement with that by seriplane test.It is very possible to use the principal component analysis for the analysis and quality control of linen yarns with Uster test data.Uster evenness test method coupled with the component analysis will have good potential applications.The data also indicated that the seriplane test may be replaced by the Uster test after constructing a standard database.
