摘　　要：针对色纺纱行业中有色纤维混合后颜色预测流程繁琐、精度低的问题,在Stearns-Noechel模型的基础上,探究基于散纤维直接测色的颜色预测公式。通过数理分析改进颜色预测模型中的M值计算方法,提出ModelⅠ模型和ModelⅡ模型,并与已有的ModelⅢ模型和ModelⅣ模型进行对比。结果表明:新建立的两种颜色预测模型较已有的两种模型在颜色预测的精度上都得到了不同程度的提高,尤其是基于波长的ModelⅡ模型具有更高的精度。在45个混色样中,平均色差仅为1.4,色差小于3.0的个数占样本总数的100%,这表明新提出的颜色预测模型可应用于混色棉条生产中的颜色初步预测。In view of the problems of the complex process and low accuracy of color prediction after colored fibers are mixed in the color spinning industry,based on the Stearns-Noechel model,the author probes into a color prediction formula based on the direct colourimetry of loose fiber.Through mathematical analysis,the M value calculation method in the color prediction model is improved,ModelⅠand ModelⅡare proposed and compared with the existing ModelⅢand ModelⅣ.The results show that compared with the two existing models,the two new color prediction models are improved to varying degrees in terms of the accuracy of color prediction.ModelⅡbased on wavelength,in particular,has higher accuracy.Among the 45 mixed color samples,the mean color difference is only 1.4,and the number of samples with a color difference of less than 3.0 account for 100%of the total number of samples.This suggests that the newly proposed color prediction models can be used for preliminary color prediction in the production of mixed color slivers.
