Eco-Friendly Isolation Of Colorant From Arjun Bark For Dyeing Of Bio-Mordanted Cotton Fabric

ABSTRACT

The worldwide demand has been raised to use natural dyes in all applied fields of life due to their environmental-friendly and therapeutic nature. For the current study microwave rays as an eco-friendly extraction tool has been used to explore the natural coloring potency of Arjun bark for cotton dyeing. Arjun bark powder was exposed to microwave irradiation for up-to 5 min and was used for extraction of colorant in different media. It has been found that 50 mL of acidified methanol-solubilized extract obtained from 5 min microwave-treated powder has given excellent results when employed onto MW treated cotton at 55°C for 75 min, salt of Fe as chemical mordant and extracts of acacia and turmeric as bio-mordants employed at optimum condition has shown good to the excellent fastness ratings at grey scales. It is concluded that microwave treatment has good potential for the extraction of the colorant from Arjun bark for cotton dyeing and the application of sustainable mordants has made the process more aesthetic and sustainable.

摘要

由于天然染料对环境友好、具有治疗作用，世界范围内对天然染料的需求越来越大. 本研究利用微波作为一种生态友好的提取工具，探讨了阿琼树皮对棉花染色的天然着色能力. 将阿琼树皮粉置于微波辐射下5min，在不同介质中提取色素. 研究发现，从微波处理5分钟的粉末中获得的50毫升酸化甲醇溶解提取物在微波处理的棉花上在55°C下使用75分钟，效果非常好，以铁盐为化学媒染剂，以金合欢和姜黄提取物为生物媒染剂，在最佳条件下使用，在灰阶上显示出良好的牢度等级. 结果表明，微波处理具有很好的应用前景，可持续媒染剂的应用使该工艺更加美观和可持续.
