Due to an increase in awareness of harmful aspects of synthetic dyes among the global community, the demand of natural dyes in textile sector has been dramatically increased. The current study has been conducted to explore new eco-friendly source of natural brown colorant from arjun bark for textile. Both bark powder and silk fabrics were microwave irradiated for 1–6 min. Dyeing was performed at different variables onto irradiated and un-irradiated silk using extracts obtained from irradiated and un-irradiated powder. To make the dyeing process more sustainable, two chemical and bio-mordants were employed at optimal conditions. The results show that acidified methanolic extract from irradiated powder (RP, 8g) has given high color strength if irradiated silk (RSi) is dyed for 65 min. at 65°C using dye bath of 1 pH in presence of 7% of Na₂SO₄ as exhausting agent. Good shades and improved fastness characteristics have been obtained by employing 1% of Fe (iron sulfate) and Al (aluminum sulfate) as Chemical and 1% of turmeric and pomegranate extracts as bio-mordants. Hence, microwave radiation has not only explored the coloring efficacy of arjun bark as potential source of natural brown dye but also made its applicability under sustainable conditions.

由于国际社会对合成染料有害方面的认识不断提高，纺织领域对天然染料的需求已大大增加。当前的研究已经进行了探索，从arjun树皮中提取出用于纺织品的天然棕色着色剂的新的生态友好来源。树皮粉和丝织物都经过微波照射1–6分钟。使用从辐照和未辐照粉末获得的提取物，以不同的变量对辐照和未辐照的丝绸进行染色。为了使染色过程更可持续，在最佳条件下使用了两种化学和生物媒介。结果表明，如果将辐射丝（RSi）染色65分钟，则来自辐射粉（RP，8g）的酸化甲醇提取物具有较高的色强度。在65°C下使用1 pH的染浴在7％Na的存在下₂ SO ₄作为排气剂。通过使用1％的Fe（硫酸铁）和Al（硫酸铝）作为化学物质以及1％的姜黄和石榴提取物作为生物媒质，可以获得良好的阴影和改善的色牢度特性。因此，微波辐射不仅探索了arjun树皮作为天然棕色染料的潜在来源的着色功效，而且使其在可持续条件下具有适用性。
