基于原色纤维混配色织物的呈色特性与影响因素分析

Coloration characteristics and influencing factors of colored spun fabric based on primary-color fibers blending

针对色织物加工中存在颜色管理效率低下、色样传递周期长等问题,建立了基于离散Fréchet距离准则与色差分析公式的色度学指标联合表征模型;同时,以聚类分析理论为基础,构建了基于类内距离与类间距离的色度学指标差异性判别准则,并应用于原色纤维混配色织物的色度学指标主要影响因素及一般规律分析。结果表明:建立的色度学指标联合表征模型与差异性判别准则具有理想的色度学指标表征与判别能力;当原色纤维质量配比总体差异大于1%时,其色纺织物的色度学指标差异具有显著性;同时,原色纤维的长度、种类以及捻系数差异均会导致其色度学指标的显著改变。研究结果对于最终建立原色纤维混配色预测模型以及色纺企业的实践生产均具有积极参考作用。

Aiming at the problems of low efficiency of color management and long transmission cycle of color samples in color spinning industry,a colorimetry index joint model based on discrete Fréchet distance criterion and color difference analysis formula was proposed.Meanwhile,based on cluster analysis theory,the discriminant criterion of colorimetry index based on"intra class distance"and"inter class distance"was established,and used for the analysis on the coloration characteristics and influencing factors of colored spun fabric based on primary-color fibers blending.The results show that the joint model and discriminant criterion of colorimetry index has ideal stability and adaptability.When the quality ratio difference of primary-color fibers is greater than 1%,the colorimetry index of colored spun fabric has significant difference.At the same time,the difference of length,type,and twisting coefficients of primary-color fibers will cause significant differences in colorimetry index of colored spun fabric.The result has a positive guiding role in final establishment of the prediction model of the mixed color of the primary-color fibers and the practice and production of color spinning enterprise.
