Eco-Friendly Dyeing Techniques for Banana Fibers from Banana Application in the Sri Lankan Context. Promoting Sustainable Coloration Methods

Sustainable natural dyeing is a process that aims to minimize the environmental impact of banana fiber dyeing while promoting the use of eco-friendly and renewable resources. This approach involves the use of plant-based dyes. This study explores the application of natural dyes for banana fiber, a versatile and abundant natural material. This study explores the potential of natural dyes derived from locally sourced materials such as banana pseudostem sap (Musa acuminata) extracted juice, jamun fruit (Syzygium cumini), coconut shells powder (Cocos nucifera), Ceylon green spinach (Basella alba), and Tree Turmeri (Coscinium fenestratum) dyeing for banana fibers. Each of these natural dye sources offers a wide range of pastel color palette with diverse colors in the dyeing process. Some of these dye sources, such as banana pseudostem sap juice and jamun fruit juice, possess unique chemical properties that can create interesting visual effects. One of the key aspects explored in this study is the mordant-free dyeing techniques for banana fibers. Banana fibers in mordant-free dyeing techniques have the essential ability to provide long-lasting colors, color fastness, and dye absorption without the need for mordants. By exploring the potential of natural dye sources and mordant-free dyeing techniques for banana fibers, this chapter aims to promote sustainable and vibrant coloration options in the textile and fiber industry in Sri Lanka. The extraction processes, dyeing techniques, and color fastness properties of these natural dyes are examined to assess their viability in textile applications. By providing comprehensive information on selected natural dye sources of five (5) and their properties for dyeing banana fibers, this study aims to promote sustainable and environmentally conscious practices in the fiber and textile industry and economic opportunities for local communities in Sri Lanka. Understanding the potential of natural dyes offers opportunities for creating unique and eco-friendly textiles, enhancing the market appeal of banana fiber-based products, and contributing to a more sustainable future.
