The cleaner methods for functional colouration of textiles are in huge demand. The use of toxic metallic mordants for achieving such an objective makes the entire process unsustainable. The biomolecules present in various green extracts can be utilized for achieving functional colouration. Kigelia Africana (KA) and Terminalia chebula (TC) are known as a rich source of biomolecules possessing antioxidant and antibacterial activities. In the present work, a bio-mordant Terminalia chebula was utilized as a mordant for natural dyeing of wool using Kigelia Africana natural dye. The colouration and functional properties were assessed using standard methods. The dyed wool fabric with satisfactory colour values and fastness properties was obtained. The dyed wool displayed antioxidant activity up to 99.41%, antibacterial activity up to 97.8% and excellent UPF. The novel sustainable option for functional colouration of wool was thus explored.

纺织品功能性着色的更清洁方法的需求量很大。为了实现该目的而使用有毒金属媒染剂使整个过程不可持续。各种绿色提取物中存在的生物分子可用于实现功能性着色。非洲黑果（Kigelia Africana，KA）和白头翁（Terminalia chebula，TC）被称为具有抗氧化和抗菌活性的生物分子的丰富来源。在目前的工作中，使用了一种生物媒媒Terminalia chebula作为媒染剂，使用Kigelia Africana对羊毛进行天然染色天然染料。使用标准方法评估着色和功能特性。获得了具有令人满意的色值和牢固性的染色羊毛织物。染色羊毛显示出高达99.41％的抗氧化活性，高达97.8％的抗菌活性和优异的UPF。因此探索了羊毛功能性染色的新型可持续选择。
