Increasing eco-consciousness among consumers is creating an expanding niche market for textiles coloured using natural dyes. Natural dyes are derived from different parts of plants, animals (insects and invertebrates) minerals. Although plant sources common, a growing global population makes them compete with food crops. Hence, there need to investigate alternate avenues procuring This research...

It is felt very essential to develop a knowledge base on dye chemistry and effects of dyeing process variables as well as rate of dyeing and chemical kinetics of dyeing for different natural dyes and fibres combinations to manipulate the processes of natural dyeing efficiently in order to get maximum color yield in economical way. A review on the effects of dye extraction medium, optimum concen...

Syntheses of analogues historical indigo and Maya blue pigments using an inquiry-based approach are presented. Derivatives were synthesized (in particular Tyrian purple) used as vat dyes for dyeing cotton or wool fabrics mixed with a sepiolite clay to create new hues colors blues green chemistry hydrothermal microwave synthesis. The allows very quick preparation analogue (typically 1 h) while i...

Natural products have gained worldwide favor due to their sustainable and ayurvedic nature. In this study, rose containing anthocyanin was explored as a source of yellowish–pink natural colorant for wool dyeing using various solvents (aqueous, alkaline, acidic, basified methanol). Dyeing performed by optimizing the following parameters: pH, temperature, time, salt concentration. It observed tha...
