摘要

Policies and increasing awareness of the environment are causing a revolutionary change in the textile coloration toward sustainability. The search for green alternatives for conventional synthetic pigments and binders, which frequently present severe hazards to human health and the environment, is at the heart of this movement. This review analyzes different ways to extract natural pigments and eco-friendly binders from biodegradable sources such as plants, microbes, and insects based on their respective hues while evaluating the advantages to the environment. The functionalities, effect on color quality, and scalability of extraction methods such as water-based, enzymatic, and fermentation are discussed. It emphasizes the benefits of them, such as their biodegradability and decreased toxicity to the environment. Natural pigments and binders are becoming widely used, but certification and supply chain management issues make things more complicated. In pigment printing, binders improve color permanence, adhesion, and resilience to adverse conditions by fixing pigments to the textile substrate. Beyond these challenges, breakthroughs in extraction techniques provide encouraging ways to improve the pigment's and the binder’s performance. This review indicates that these eco-innovations can significantly promote more environmentally sustainable textile practices with continued research and technical advancements. This transition is essential for encouraging eco-friendly coloration techniques and minimizing the textile industry’s environmental impact.
