色纺机织物组织结构对其呈色特性的影响

Influence of fabric weaves on characteristics of colored patterns in color-woven fabrics

针对色纺加工中机织物组织结构参数变化而导致的色纺纱线选配调整难题,提出了一种结合均匀三元结构描述子的图像混合特征提取算法,对色纺机织物组织结构与呈色一般规律展开研究。以聚类分析理论为基础,构建了基于特征类内距离的呈色特性分析模型,并用于色纺纱线与其机织物呈色特性与颜色传递的表征。结果表明:建立的图像特征提取算法与呈色特性分析模型具有理想的色度学指标表征与判别能力;对于具有不同质量配比与捻系数的色纺纱而言,不同的织造过程均会降低其呈色的差异性与层次感;同时,相较于平纹与缎纹,斜纹对织物呈色差异性弱化的能力最强。

In view of difficulties in selecting yarns caused by changes in fabric structure parameters in color weaving process,a feature extraction algorithm for hybrid images was proposed based on the use of a uniform-model three structure descriptor.According to the cluster analysis theory,a coloration characteristics analytical model based on″intra class distance″was established,and it used for color transfer and characteristics description between colored spun yarns and its fabrics.The results show that the image feature extraction algorithm and the coloration characteristics analysis model have good colorimetry index representation and discrimination ability,for the colored spun yarns with different mass ratios and twisting coefficients,different weaving processes would reduce the color difference and stereoscopy.In addition,compared with the plain weave and satin weaves,twill weaves have the strongest ability to weaken the color difference of the fabric.
