Abstract: This study demonstrates the possibility of one step printing and multifunctional finishing of wool fabrics using synthesized selenium nanoparticles (Se-NPs) as stable functional colorant. Se-NPs formation was emphasized using visible changes, UV-visible absorption spectra, and transmission electron microscopy (TEM) analysis. The UV-visible spectra and TEM analysis confirmed the synthesis of spherical well-dispersed Se-NPs. The examination of printed samples was conducted by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray powder diffraction analysis (XRD), that revealed the successful deposition of Se-NPs onto wool fabric surface. The color, UV protection, and antimicrobial properties of Se-NPs printed wool were also evaluated. The printed samples had outstanding fastness characteristics to washing, rubbing, and light. Moreover, Se-NPs printed samples were found to possess outstanding antimicrobial activities, excellent UV-protection properties with a remarkable durability after 10 washing times without any negative impact on the printing and softness characteristics.

as well as enhancing the properties of printed materials. Recently, prominent possibilities of nanoparticles (NPs) can be effectively applied for producing textiles with multifunctionalities. A number of studies have been made for imparting functionalities to different textiles, such as antimicrobial, UV-blocking, and self-cleaning properties [12-15], as well as many approaches were interested in their preparation and characterization, as each of the NPs has different colors indicated by their surface plasmon resonance (SPR) peaks [16]. Lately, new approaches for applying NPs as multifunctional agent imparting coloration, antimicrobial, and UV protection properties using silver, cupric, silica, and gold NPs for wool fabrics [17-19], nylon [20], cotton, and polyester [21,22] have been reported. Selenium nanoparticle (Se-NP) with a bright red color has become the new research target, because it exhibits low toxicity compared to selenium compounds and have excellent bioactivities [23]. Some studies also investigated the antimicrobial properties of synthesized Se-NP and its potential biological application as anticancer agent [24-27]. Its surface plasmon resonance (SPR) property in textile coloration and its functional properties in textiles have not been reported yet. Accordingly, the main task of this work was to introduce for the first time a cost-effective eco-friendly app
