Yarn-dyed fabric is often woven from warp and weft yarns in the same color depth to ensure a uniform color appearance. The difference in color depth between warp and weft tends to result in the uneven color of the yarn-dyed fabric. This article aims to establish a color tolerance for yarn-dyed fabric that can be woven with a qualified color appearance but from the warp and weft yarns in different color depths. A total of 27 yarn-dyed fabric samples in three color series (red, yellow, and blue) were evaluated by using the yarn-dyed fabric from warp and weft yarns in the same color depth of 2% (on weight of fabric, owf) as the standard. Visual assessment and instrumental measurement of color were carried out to establish the color tolerance ellipse that was defined as CMC (Color Measurement Committee) color differences (2:1) of no more than 1.00. It was found that the color strengths (K/S) and color differences (ΔECMC(2:1)) of these fabric samples for each color series had linear relationships with the color depths of warp and weft yarns. The color tolerance ellipses indicated that, even though the warp and weft yarns had an apparent color difference, they could be woven in fabrics with relatively uniform color appearance and meet the requirements for yarn-dyed fabric. This work provided valuable insight into the production of qualified yarn-dyed fabrics from unqualified dyed yarns.

不同色深纱线色织织物颜色容差的建立

色织织物通常由相同颜色深度的经纱和纬纱编织而成,以确保颜色均匀。经纬线色深不同,容易造成色织织物颜色不均。本文旨在建立色织织物的色度容差,该色织织物可以从不同色深的经纱和纬纱织造出合格的颜色外观。采用经纬纱色深相同2%(以织物重量计,owf ) 作为标准。进行颜色的视觉评估和仪器测量以建立定义为不超过 1.00 的 CMC(颜色测量委员会)色差 (2:1) 的颜色容差椭圆。K / S ) 和色差 (Δ E CMC(2:1) ) 的这些织物样品的每个颜色系列与经纱和纬纱的色深呈线性关系。色差椭圆表示,即使经纱和纬纱有明显的色差,它们也可以织成颜色外观相对均匀的织物,满足色织织物的要求。这项工作为从不合格的染色纱线生产合格的色织织物提供了宝贵的见解。
