Abstract：
The use of synthetic dyes in the textile industry is mostly non-degradable, which are carcinogenic and pollute the environment severely. Natural dyes have gained significant attention recently due to their potential to mitigate the environmental challenges associated with synthetic colorants. This investigation is centered around the extraction of natural dyes sourced from mahogany trees and the exploration of environmentally friendly techniques for coloring jute fabric. The derived dyes were procured from distinct segments of the mahogany tree: namely, the bark, fruits, and wood remnants. Employing an aqueous extraction methodology, inherent coloring agents were meticulously separated and subsequently applied to jute fabric subsequent to appropriate mordanting employing a variety of mordant categories. An exhaustive assessment encompassing wash, light, rubbing, and perspiration resistance was conducted on jute fabric that was subjected to dyeing using three distinct variants of mahogany tree-derived dyes. Notably, jute fabric treated with wood wastage-sourced dye exhibited commendable to exceptional resistance properties. The efficacy of this dyeing process was further substantiated through diverse characterization techniques, inclusive of scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR), which unequivocally affirmed the successful bonding of mahogany-derived dyes onto the surface of the jute fabric. The textile industry, particularly dyeing operations that use large, designed colors and synthetic chemicals, is wreaking havoc on the sea-going environment by dumping emissions directly into bodies of water. Synthetic colors are commonly used to dye jute fabric, which has major health and environmental consequences. Therefore, concerning the environmental challenges, the dyeing of jute fabric using naturally extracted dyes from mahogany trees can be a suitable alternative to synthetic dyes in the textile industry.
摘要：
纺织工业中合成染料的使用大多是不可降解的，它们是致癌的，严重污染环境。由于天然染料具有减轻与合成着色剂相关的环境挑战的潜力，最近获得了极大的关注。这项调查的重点是提取源自红木树的天然染料，以及探索黄麻织物着色的环保技术。衍生的染料是从桃花心树的不同部分获得的：即，树皮，水果,和木材残留物。采用水性提取方法，固有的着色剂经过精心分离，随后在使用各种媒染剂类别进行适当的媒染后，将其应用于黄麻织物。详尽的评估包括清洗，光,摩擦,并且在使用三种不同的桃花心木树衍生染料进行染色的黄麻织物上进行了抗汗性。值得注意的是,用木材废料来源的染料处理过的黄麻织物表现出值得称赞的优异的抗性。这种染色过程的功效通过不同的表征技术得到进一步证实，包括扫描电子显微镜（SEM）和傅里叶变换红外光谱（FTIR），明确肯定了桃花心木衍生染料成功粘合到黄麻织物表面。纺织业,特别是使用大量的染色操作，设计的颜色和合成化学品，通过将排放物直接倾倒入水体，正在对海上环境造成严重破坏。合成颜色通常用于染色黄麻织物，这对健康和环境有重大影响。因此,关于环境挑战，在纺织工业中，使用红木树的天然提取染料对黄麻织物进行染色可以替代合成染料。
