The main goal of this study is to develop a facile eco-friendly method for antibacterial/ultraviolet (UV)-blocking functionalisation using various green bioactive functional additives namely neem, jojoba, argan, aloe vera, ginger, and tulsi. In addition, pigment coloration of cellulosic substrates including cotton, viscose, cotton/viscose, and cotton/linen using pigment colourants and appropriate printing auxiliaries in one step was used. The experimental results revealed that the durability, improvement in the imparted antibacterial/UV-blocking functional properties and enhancement in the depth of the obtained pigment prints followed a decreasing order: tulsi > ginger > aloe vera > argan > jojoba > neem â‰« none, keeping other parameters constant. The obtained data also demonstrated that the developed pigment prints exhibited remarkable functionalities and depth of shade after 15 washing cycles. Moreover, it was observed that improvement in the imparted functional and coloration properties were a function of types of cellulosic substrate and the kind of colourant. Scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analysis for selected samples confirmed the surface modification, morphology changes and immobilisation of the used active ingredients onto the treated substrates.

使用生物活性添加剂的纤维素织物的耐用表面功能化和颜料着色

本研究的主要目标是使用各种绿色生物活性功能添加剂，即印楝、荷荷巴油、摩洛哥坚果、芦荟、生姜和图尔西，开发一种简便、环保的抗菌/紫外线 (UV) 阻断功能化方法。此外，在一个步骤中使用颜料着色剂和适当的印刷助剂对包括棉、粘胶、棉/粘胶和棉/亚麻在内的纤维素基材进行颜料着色。实验结果表明，所获得的颜料印花的耐久性、赋予的抗菌/紫外线阻隔功能特性的改善和深度的增强呈递减顺序：图尔西 > 生姜 > 芦荟 > 摩洛哥坚果 > 荷荷巴 > 楝树 ≥ 无，保持其他参数不变。获得的数据还表明，经过 15 次洗涤循环后，所开发的颜料印花表现出显着的功能和色调深度。此外，据观察，赋予的功能和着色特性的改善是纤维素基材类型和着色剂种类的函数。所选样品的扫描电子显微镜 (SEM) 和能量色散 X 射线光谱 (EDX) 分析证实了所用活性成分的表面改性、形态变化和固定在处理过的基材上。
