The silk fabrics were matching dyed with three natural edible pigments (red rice red, ginger yellow and gardenia blue). By investigating the dyeing rates and lifting properties of these pigments, it was observed that their compatibilities were excellent in the dyeing process: dye dosage 2.5% (omf), mordant alum dosage 2.0% (omf), dyeing temperature 80 °C and dyeing time 40 min. The silk fabrics dyed with secondary colors exhibited vibrant and vivid color owing to the remarkable lightness and chroma of ginger yellow. However, gardenia blue exhibited multiple absorption peaks in the visible light range, resulting in significantly lower lightness and chroma for the silk fabrics dyed with tertiary colors, thus making it suitable only for matte-colored fabrics with low chroma levels. In addition, the silk fabrics dyed with these three pigments had a color fastness that exceeded grade 3 in resistance to perspiration, soap washing and light exposure, indicating acceptable wearing properties. The dyeing process described in this research exhibited a wide range of potential applications in matching dyeing of protein-based textiles with natural colorants. [ABSTRACT FROM AUTHOR] |
