A new approach for an eco-friendly multi-functionalization of cotton/wool (C/W) and viscose/wool (V/W) blended fabrics was investigated. In this study, Ag-nanoparticle (Ag-NP) and/or ZnO-nanoparticle (ZnO-NP) functional agents were incorporated into the finishing bath along with citric acid (CA) or succinic acid (SA) as ester-crosslinking or esterifying agent, and sodium hypophosphite catalyst using the padding technique. The obtained results indicated that the extent of multi-functionalization expressed as antibacterial activity, UV-blocking functionality and wrinkle recovery ability were determined by kind of nanomaterial, nature of carboxylic acid, i.e., bi- or tri-functional and type of substrate. The results also demonstrated that blended fabrics finished with Ag-NP/ZnO-NP/CA/SHP nano-finishing formulation exhibited outstanding durable multi-functional properties even after 10 washing cycles. In addition, the change in surface morphology and the existence of Ag and/or Zn onto the selected V/W fabric surfaces have been confirmed by SEM and EDX analysis respectively.

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.
