摘　　要：研究基于视觉感知的主客观转杯混色纱颜色评价方法。简要介绍了颜色主观评价法和基于3种色差公式的客观评价法。选用红、黄、蓝3种原液着色粘胶散纤维作为试验原料,纺制53个混配比例的粘胶58.3 tex转杯纱颜色样品。对色纺纱样品对的色差进行人眼视觉评价试验和色差公式计算。通过PF/3和STRESS评价指标研究目测感知量与色差计算值两组数据的相关程度,采取误判率及反射率偏差方法对观察者数据准确性加以佐证,探究针对于色纺纱与人眼一致性程度最为相符的色差公式。研究结果显示:CMC(2∶1)、CIELAB、CIEDE2000色差公式的PF/3和STRESS值分别为19.02、22.33、41.24和24.72、28.78、40.47。在该研究范围内,CMC(2∶1)色差公式的预测性能最优。Subjective and objective color evaluation method of rotor mixed colored spun yarn based on visual perception were studied.Subjective evaluation method of color and the objective evaluation method based on three chromatic aberration formulas were briefly introduced.Original solution colored viscose fiber with three colors of red,yellow and blue were selected as test raw materials.53 blending ratios of 58.3 tex viscose color samples are spun by rotor spinning.Color difference of color spun samples was tested and calculated by the human eye vision evaluation and color difference formula.The correlation between visual perception and calculation value was studied by PF/3and STRESS evaluation indexes. The accuracy of observer data was supported by false error rate and reflectance deviation method to explore the chromatic aberration formula which was the most consistent with the consistency of the human vision about color spun yarn.Results showed that PF/3 and STRESS values of CMC(2∶1),CIELAB and CIEDE2000 were 19.02,22.33,41.24 and 24.72,28.78,40.47 respectively.Within the scope of the study,the CMC(2∶1) chromatic aberration formula had the best predictive performance.
