Abstract: The textile sector ranks among the largest contributors to global pollution, with synthetic dyes playing a major role in environmental harm. This research centres on the design and creation of sustainable laptop bags utilizing annatto natural dye, a plant-derived colorant extracted from the seeds of Bixa Orellana. The objective of this study is to investigate the viability of annatto natural dye as a sustainable substitute for synthetic dyes, thereby minimizing the ecological footprint of textile manufacturing. Cotton fabric was chosen as the primary material, and the annatto dye was extracted and applied with various mordanting agents. The findings indicated that annatto natural dye can yield a spectrum of vibrant colours, ranging from yellow to orange-red, while exhibiting excellent colourfastness and durability. The laptop bags designed in this study fulfilled both functional and aesthetic criteria, showcasing the practicality of incorporating annatto natural dye in textile production. This research advances sustainable practices within the textile industry by advocating for the use of natural dyes and decreasing dependence on synthetic chemicals. The results have significant implications for the textile sector, promoting the transition to environmentally friendly production techniques and sustainable materials.
