摘　　要：探讨DR值及其曲线与织物外观的相关性。介绍了纱线条干仪测得的各种条干不匀指标,深入地研究了DR值及其曲线的特点和应用方法,提出了几个运用偏移率预测织物外观质量的指标和图形,并从理论分析和实际测试两个方面进行了说明和验证。认为:与条干CV_(m)值相比,DR值及其曲线与织物外观质量相关性更强。Correlation of deviation rate value and its curve on fabric appearance was discussed.Various uneveness indicators measured by yarn eveness tester were introduced.Characteristic and application method of deviation rate value and its curves were studied in-depth.Several indexes and graphs for predicting fabric appearance quality which using the offset rate were proposed.From theoretical analysis and actual test,the results were described and verified.It is considered that compared with evenness CV_(m) value,deviation rate value and its curve have a stronger correlation with fabric appearance quality.
