Recently, there has been a great deal of interest to circumvent the environmental problems associated with manufactured colouring agents by using natural dyes. This study focuses on extracting natural dyes from mango leave and mango peel and finds sustainable ways of cotton dyeing. Natural colouring agents were extracted using an aqueous extraction technique and the cotton fabric was dyed using the extracts followed by mordanting using different mordant types. The dyeing performance of extracted colouring agents were assessed in terms of colour values, dye absorption (%), colour fastness properties and colour strength. The mordanting mechanisms of the extracted dyes were also proposed. Dyes extracted from mango leaves results in more colourised material than dye drived from mango fruit extract. Moreover, the dye extract exhibited a deeper shade. Result also shows that cotton fabric dyed with the same dye extract but with different type of mordants resulted in a fabric that showed diverse colours. Moderate to good fastness values were recorded (4–5). Considering the dyes exhibited excellent colour fastness, it can be concluded that the natural dyes extracted from various parts of the mango plant could be an effective colouring agent for use on cotton fabrics.

近来，人们非常关注通过使用天然染料来解决与制造的着色剂有关的环境问题。这项研究着重于从芒果叶和芒果皮中提取天然染料，并找到了可持续的棉花染色方法。使用水性提取技术提取天然着色剂，并使用提取物对棉织物进行染色，然后使用不同媒染剂类型进行媒染。根据色值，染料吸收率（％），色牢度特性和色强度评估提取的着色剂的染色性能。还提出了提取染料的媒染机理。从芒果叶中提取的染料比从芒果果实中提取的染料产生更多的有色物质。此外，染料提取物表现出更深的阴影。结果还表明，用相同的染料提取物但媒染剂类型不同的棉织物染色后的织物显示出多种颜色。记录到中等至良好的牢度值（4-5）。考虑到该染料表现出优异的色牢度，可以得出结论，从芒果植物各个部位提取的天然染料可以是用于棉织物上的有效着色剂。
