Color Characteristics, Color Gamut Range and Color Value of Acer Ginnala Dyes on Wool Fabric

ABSTRACT

In this study, natural dyes were extracted from acer ginnala dried leaves and applied on wool fabric. The preferred mordant and post-mordant dyeing performance on wool fabric with Acer ginnala were confirmed by color strength (K/S). The influence of different factors on color characteristic value was revealed and qualitative analysis was carried out on the samples dyed by different concentration of dyeing solution and dyeing times. The experimental results showed that the application value of post-mordant dyeing of acer ginnala wool fabric was the largest. Moreover, the color characteristics values of post-mordant dyeing acer ginnala wool fabric influenced by different factors was lightness L* (14.89-59.57), purity C* (0.81-15.76), hue b* (0.03-15.74), hue a* (0.21-1.31) by order. The hue angle h° is between 92° and 339°, which gradually transits from yellow to orange to red and then to purple. A total of 19 colors were dyed, including 2 colors of Pantone, 4 colors similar to Pantone, 9 colors very different from Pantone, and 4 colors totally different from Pantone. All samples soap-washing fastness, rubbing fastness and light fastness are above grade 3, which showed a wide prospect of application.

摘要

本研究从干燥的茶条槭叶中提取天然染料，并将其应用于蛋白质(毛)织物上。通过染色深度（K/S）确认了染色效果最佳的媒染剂以及茶条槭上染毛织物后媒染的染色性能，探讨了不同影响因素对颜色特征值的影响，并对染液质量浓度和染色次数所染试样进行定性分析。实验结果表明，茶条槭毛织物后媒染的应用价值最大，茶条槭毛织物后媒染颜色特征值受影响因素影响的强弱依次为明度L*值、纯度C*值、色相b*值、色相a*值。明度L*值的范围在14.89-59.57之间，纯度C*值范围在0.81-15.76之间，色域范围中色相b*值范围在0.03-15.74之间，色相a*值范围在0.21-1.31之间。色相角h°在92°到 339°之间，色调从黄区至橙区至红区再向紫区逐渐过渡。共染制19种色彩，其中潘通色彩2种、与潘通色彩相近4种、与潘通色彩区别较大9种、与潘通色彩不同4种，所有试样的耐皂洗牢度、摩擦牢度及日晒色牢度均在3级以上，具有较好的使用价值。

Highlights

• Rarely applied to plant dyeing, Acer ginnala shows a massive potential for black dyeing.

• An experiment was conducted to optimize the process parameters of black dyeing by Acer ginnala and analyze the law of color change for black dyeing by Acer ginnala given different factors;

• The range of color gamut as achieved through black dyeing by Acer ginnala was determined, and color characterization was performed by using the CIE-Lab color space model;

• The commercial value of Acer ginnala in garment dyeing was confirmed by conducting the color fastness test and drawing comparison with the Pantone color card.
