纺织材料多元色彩耦合机理和显色作用机制的研究

数码印花技术具有自动化程度高、能耗低、污染小、工艺简化等优势，可以突破传统印花的花型限制、复制精细且生动的颜色，在纺织服装业具有良好的应用前景。色彩的运用在产品设计和时尚产业的发展至关重要，然而以纺织材料为特征的面料上，数码印花色彩的选择存在色域偏小、色差较大的问题，产品最终效果与设计原样差别较大。数码印花技术依赖纸张数字印刷色彩处理方式，而纺织材料的结构特征如覆盖系数、密度和光泽度等与显色呈色的耦合关系尚不清晰。本项目以纺织基材料和青-品红-黄-黑四色墨水为研究对象，研究内容包括：（1）纺织材料的结构特征对显色呈色规律的影响；（2）适用于纺织材料的色域模型和颜色复制方案；（3）基于感性工学的多色彩颜色复制视觉评估。项目研究成果不仅有助于深入认识纺织材料显色呈色作用规律和影响因素，且为纺织材料的多色彩颜色复制提供优化建议，为现代纺织品印花技术设计和产品设计奠定理论理论和技术支撑。

Textile digital printing technology has the advantages of highly automation, low energy consumption, low water waste, and simple manufacturing process, etc. It also breaks through the limit of traditional textile print patterns, and reproduce delicate and vivid colors. It is believed that textile digital printing will be the future trend in textile and apparel industry. The application of colors is important in product design and fashion industry development. However, the selection of color on textile materials is still quite limited. The relatively small color gamut and color mismatch of color reproductions lead to big difference between original design and final product. The textile digital printing technology was developed from paper-based inkjet printing technology, so does the colorimetric data transformation. It doesn’t consider the effects from structural characteristics of textile materials, such as the cover factor, fabric density and glossiness, etc. Based on textile materials and four-color based inks (Cyan, Magenta, Yellow and Black), this project proposes to explore (1) the relationship between the structural characteristics and color performance; (2) the optimized workflow to improve the color gamut and color reproduction on the textile materials; (3) Multicolors evaluation based on Kansei engineering model. The research will not only provide a deeper understanding of the mechanism and key factors that affect color appearance and color rendering on textile materials, but also suggest the optimized workflow for color reproduction on textile materials, also support technical theoretical research for modern textile technology and product designs.
