摘要/Abstract

摘要：

为便于原配色丝的纺前计算机辅助设计,从光在单丝间的传播角度出发,根据单丝的透射率、反射率和排列方式,提出了一种颜色预测模型。采用红、绿、黄、蓝4种不同颜色的薄膜代替单丝,将任意2种颜色的薄膜裁剪为不同的大小,通过相互叠加的方式制作了12个复丝试样。使用Datacolor测色仪测试了试样的混合色,同时计算其与模型预测的混合色之间的色差,并通过皮尔森相关性分析对造成色差的因素进行了讨论。结果表明:预测色差均值为0.43 CMC(2∶1)色差单位;复丝的饱和度和色相角对预测色差有显著影响,即预测色差随着复丝饱和度的增大而减小,随着复丝色相角的增大而增大。

Abstract:

In order to facilitate the computer-aided pre-spinning design of original color-matching yarns, a color prediction model was proposed based on the transmittance, reflectance and arrangement of the monofilament from the perspective of light transmission between monofilaments. Red, green, yellow, and blue colored films instead of monofilament were used. The films of any two colors were cut into different sizes, and 12 multifilament samples were made by superimposing the colored films. The mixed color of the sample was tested with datacolor colorimeter, and the color difference between the mixed color tested by the colorimeter and predicted by the model was calculated. The factors causing the color difference were discussed through Pearson correlation analysis. The results show that the average predicted color difference is 0.43 CMC (2∶1) color difference unit. The saturation and hue angle of the multifilament has a significant impact on the predicted color difference, showing that the predicted color difference decreased with the increase of the saturation of the multifilament, and increases with the increase of the hue angle of the multifilament.

Key words: color mixing of fiber, reflectance prediction, chemical fiber filament, optical color mixing, computer-aided design
