Biopolymers in Sustainable Textile Dyeing and Printing

This chapter explores the role of biopolymers in enhancing textile dyeing, printing, and functional finishes. Biopolymers, derived from renewable sources, offer a sustainable alternative to conventional synthetic chemicals in the textile industry. They improve dye uptake, colour fastness, and print quality, enhancing textile performance. Biopolymers serve as natural dye carriers, promoting eco-friendly dyeing practices and reducing reliance on synthetic dyes. Additionally, biopolymer-based thickeners and binders enable precise and vibrant textile printing while supporting environmental sustainability. The development of biopolymer coatings for antimicrobial and UV-protection finishes enhances textile functionality. Comprehensive performance and sustainability assessments guide responsible manufacturing practices, ensuring environmentally conscious and socially responsible textile production. As the industry embraces biopolymers, future research is expected to advance their engineering and applications, contributing to a greener and more sustainable textile sector.
