| Résumé : |
Microbial colorants are becoming popular because they have the potential to overcome disadvantages of synthetic and natural dyes. However, for commercialization, their after dyeing characteristics especially light fastness needs to be improved preferably using natural agents to make the complete dyeing process eco-benign. Therefore, in this study, eco-friendly tannins and antioxidants were employed to improve the light fastness of wet blue goat nappa skin dyed with the colorant of Penicillium minioluteum. Their effect on color strength, fastness properties, and mechanical strength were also assessed. As a result, the only sample treated with tannic acid before dyeing showed moderate light fastness with improved perspiration, tear, and tensile strength. Further improvement in light fastness was recorded when tannic acid treated and dyed sample was padded with vitamin E - gum acacia emulsion (10% vitamin E, 10% glycerol, 4.5% gum acacia powder). Here, improvement in perspiration and rub fastness was also noticed. |
