In this research for the first time, surface functionalization of polyester fibers was performed via one-step, facileand clean strategy through green synthesis and deposition of iron oxide nanoparticles for photocatalytic and magneticapplications. The commercial ash of Seidlitzia Rosmarinus plant was used as a natural alkaline source for nanoparticlessynthesis as well as surface modification of polyester substrate and iron sulfate as metal precursor. The presence of iron oxidenanoparticles on polyester fibers was proved by X-ray diffraction analysis, energy-dispersive X-ray spectroscopy, mapping,field-emission scanning electron microscope images and Fourier transform infrared spectra. The fabricated samples exhibitedvery good photocatalytic activities toward methylene blue decoloration about 95.45 % after 48 h exposing to sunlightirradiation. In addition, they indicated appropriate magnetic properties with saturated magnetization of 2.30 and 1.69 emu/gat room temperature. The coloring effect, weight change and wettability behavior of the fabricated samples were alsoinvestigated. The mentioned route in this paper can simply be scaled up as an eco-friendly and scalable route for surfacefunctionalization of polymeric substrates via synthesis and deposition of iron oxide nanoparticles to acquire durable photoand magneto activities on polymers for different applications.

The lowering intake of organic dyes and their auxiliaries by employing nanoparticles for some specialtextile coloration is novel and interesting topic. Nonetheless, application of reducing, stabilizing andother chemical agents in textile nano-coloration is still undesirable from both environmental andhuman/aquatic life viewpoints. This research renders a facile technique for wool coloration throughlocally forming selenium nanoparticles using sodium selenite without using other chemicals. Beingindustrially enforceable, free from use of additional chemicals, showing photo-active ability to discolorthe dyeing effluent and low-toxic colorant are the main privileges of the used method. The wool fabricswere colored light to dark orange depending on coloration time and concentration of sodium selenite. Also, the color fastness properties against washing, rubbing and acid/alkaline spotting of prepared sampleswere excellent. Moreover, the colored fabrics indicated reasonable bactericidal and fungicidal performancestoward Escherichia coli, Staphylococcus aureus and Candida albicans (95, 70 and 100 %,respectively) and still remained compatible with human skin. The in-situ synthesis of selenium nanoparticleson wool fabric not only colored the wool but also promoted the UV-protecting performance by61.82 %, photocatalytic activity through methylene blue discoloration under sunlight by 97.22 % and tensilestrength by 11.27 %.
