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.
