多通道转杯纺混色纱的Friele配色模型

为探究多通道转杯纺的混色效果,利用Friele理论建立转杯多元基色混色纱的配色模型。将红、黄、蓝3种颜色纤维条纺制二组分和三组分样本,计算关于转杯混色纱的Friele理论模型参数,分别得到二组分和三组分的模型参数,并将其与其他研究者计算的模型参数进行比较。结果显示,无论是二组分还是三组分样本,通过实验计算得到的4种模型参数均比其他研究者推荐的模型参数对多通道多元基色转杯混色纱预测结果的准确性有所提高;其中与赋值法计算的模型参数相比,与波长相关的模型参数预测二组分和三组分的样本色差均值分别减少了0.42和0.48,容差范围为1时,样本合格率分别提高了33%和50%,在各波长下计算得到的模型参数能更好地预测多通道转杯纺多元基色混色纱的颜色。

Friele color matching model of multi-channel rotor-spun mixed color yarn

In order to explore the blending effect of multi-channeled rotor spun, the color matching model was established by Friele theory. Model parameters of the Friele model of digital mixed color mixed yarn was calculated by the reflection of the two-component and three-component samples spun by roving of red, yellow and blue, respectively, two-component and three-component model parameters were obtained and compared with model parameters calculated by other researchers. The results show that the four model parameters calculated by this experiment are better to predict the color characteristics of multi-channeled rotor spun color-blended yarn than those recommended by the other researchers for both the two-component and three-component samples. Among them, compared with the model parameters calculated by the assignment method, the model parameters related to wavelengths for predicting the average color difference value of two-component and three-component samples reduce by 0.42 and 0.48, respectively. When the tolerance range is 1, the sample qualification rate is improved by 33% and 50%, respectively. It is concluded that the model parameters calculated at various wavelengths could better predict the color of multi-channeled rotor spun color-blended yarn.
