Potassium dichromate

Best insight from top research papers

The concentration of natural dyes extracted from plants plays a crucial role in textile dyeing. Different plants like Vitellaria paradoxa Shea butter tree bark, Acacia nilotica seed pods, henna leaves, and Sanamicky leaves have been studied for their dyeing properties. Higher concentrations of natural dyes generally lead to increased dye exhaustion on textile fabrics. For instance, in the case of Sanamicky leaves, optimizing dye bath concentration resulted in significant effects on color parameters and fabric fastness properties. The use of fixatives like potassium dichromate, mordants, and additives can further enhance the dyeing process and improve color retention on textiles. Therefore, controlling the concentration of natural dyes from plants is essential for achieving desired color intensity and fastness properties in textile dyeing processes.
