In this work, compounds that may be utilized as multifunctional binding materials were developed with the goal of enhancing both the functional and color qualities of the printed apparel without requiring the application of extra pre-treatments or finishing techniques. Accordingly, two water-borne polyurethane acrylates (PUA), with an aliphatic and an aromatic isocyanate base, were utilized for the in-situ synthesis of zinc oxide (ZnO) nanoparticles via a facile and green route. Next, the fabricated PUA/ZnO nanocomposite frameworks were employed as dual-function binders in the pigment printing of blend fabrics (cotton/polyester and wool/polyester). By using UV-visible, FTIR and TEM tools, it was possible to verify that the produced nanocomposites had successfully formed polymer/metal oxide NP frameworks. The fabricated PUA/ZnO nanocomposite suspensions and printed blend fabrics demonstrated considerable antimicrobial activity against gram-positive and gram-negative bacteria. Additionally, the color strength and fastness properties of printed blend fabrics using the prepared binders were improved, particularly for cotton/polyester blends. Also, a significant enhancement in ultraviolet protection activity within nanocomposite-printed textiles was observed.
