Abstract
AbstractThe 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 ≫ 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.
