基于Friele模型的转杯纺黏胶混色针织物测配色系统

Color Matching Model of Viscose Color Blended Fabric Based on Friele Model

以红、黄、蓝3色原液着色黏胶短纤维为原料,采用多通道转杯纺技术,以质量比为10%的梯度纺制66种混色纱线,制备针织物样品,利用分光光度计测试其颜色特征。对Friele模型的关键参数σ在[0,1]内进行赋值以预测样品色彩,计算得出σ=0.134时双组分混色样品平均色差最小;取该值构建基于Friele模型的多通道转杯纺黏胶织物配色系统,利用全光谱配色法和所建模型预测3组分混色样品的配方比例,所得预测比例与实际比例间的平均比例误差为10.21%,平均色差为0.4561。研究结果验证了所建Friele模型的准确性,并为完善多通道转杯纺黏胶混色纺织品智能配色系统提供了依据。

66 kinds of color blended yarns were produced by using red,yellow and blue dope dyeing viscose fiber on the multi-channel rotor spinning frame with a gradient of 10%.Knitting sample fabrics were made of blended yarn and then the color were measured with a spectrophotometer.In this paper,the model parameterσof Friele model was assigned in[0,1],and the value ofσ0.134 was taken as the optimal value with the minimum average chromatic aberration of two-component mixed color samples,and a color matching system based on Friele model was constructed.Besides,the optimalσvalue was verified by full spectrum color matching method.The error of average proportion between the tested value and the predicted value of the three-component mixed color samples was 10.21%,and the value of average chromatic aberration was 0.4561.The result shows that the parameter of Friele model obtained in this paper have good prediction effect.It provides a basis to set the intelligent color matching system of viscose blended yarn in multi-channel rotor spinning.
