In the present work, β-CD, ZnO-NPs, and several eco-friendly bioactive guests, namely, cinnamon oil, lemon oil, lavenderoil, and vanillin along with environmentally benign pigment paste constituents were applied to cotton, viscose, cotton/viscose, and cotton/linen cellulosic substrates to develop durable multi-functional pigment prints in a single step using thepad-dry-thermofixation method. The developed one-step pigment coloration and multi-functionalization method resulted ina remarkable improvement in antibacterial efficacy, UV-protection ability, aroma property along with a noticeable increasein depth of the obtained pigment prints, making them very useful for a wide range of potential applications. The extent ofenhancement in the above-mentioned functional and coloration properties is governed by type of cellulosic substrate, presenceof β-CD/ZnO-NPs, type of bioactive agent as well as kind of pigment colorant. Among the used bioactive agents, lavenderoil proved to be the best for attaining multi-functional and pigment coloration properties, keeping other parameters constant. The obtained results also demonstrated that increasing washing cycles up to 15 washes resulted in a slight decrease in theimparted functional and coloration properties, regardless of the used cellulosic substrate. Both SEM images and EDX spectraconfirmed the surface modification and ZnO-NPs immobilization onto the selected fabric surfaces. Mode of interactionsamong the different printing paste constituents and the cellulosic substrates were also suggested.
