The conventional methods of coloring and functionalizing fabrics are characterized by significant energy use, inefficiency in terms of time, and the utilization of numerous chemical substances. The urgent need for cost-effective and environmentally friendly natural dyeing and finishing has arisen in order to address the limitations associated with current methods. Herein, the natural dyes are extracted from neem wood waste and applied for natural jute fabric coloration and functionalization. The optimization of the dyeing parameters is determined using Taguchi design through L9 orthogonal array. The jute fabric dyed under optimized conditions showed higher color strength value of 1.82 as well as the satisfactory level of fastness properties of 4–5, 4, 3–4, 4–5,4 and 4–5 for wash, dry rubbing, wet rubbing, alkaline perspiration, acid perspiration and light, respectively. The structural characterization, employing both scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), provided valuable insights into the dyeing process of jute fabric using neem wood waste. SEM images, although limited to grayscale and offering insights primarily into surface morphology changes, indicated alterations in the fiber surface attributable to the dyeing process. Meanwhile, FTIR spectroscopy was instrumental in confirming the presence of specific functional groups and establishing interactions between the jute fiber and the extracted natural dyes from neem wood waste. The treated jute fabric also shown antibacterial efficiency against Escherichia coli and Staphylococcus aureus bacteria and the zone of inhibition (ZOI) are 8.78 ± 0.24 mm, and 9.44 ± 0.58 mm, respectively. Overall, the utilization of neem wood waste for the bio-based functionalization and coloring of jute fabric represents a sustainable approach within the textile industry, aligning with the goals outlined by the United Nations Sustainable Development Goals.
