Résumé : |
Synthetic dyes are widely used in the leather industry; some of these are carcinogenic in nature. Environmental concern leads one to seek dye products based on natural resources, which have several advantages like less toxicity, biodegradability, etc. The research work presented in this paper focuses on an eco-friendly dyeing process of the leather using aqueous henna leaves extract that contain lawsone, 2-hydroxy 1,4 naphthaquinone, the most prominent member of alpha – hydroxynaphthaquinone, natural dye class. The aqueous extraction from the henna leaves was studied and the best extraction conditions were found to be the maceration of the ground henna leaves in water, at temperature (> 80°C) for 60 minutes in a water bath without agitation. The color of the leather had become deeper with increasing amount of henna extract and multiple colors have been obtained depending on the type of mordants used. The henna dyeing had resulted in leathers with good rub (dry and wet) and perspiration fastness characteristics, while the light fastness characteristics were found to be moderate. |
