“…As their cover factors were intrinsically low (3.2-3.4), significantly more UV light penetrated their structure than what could be shielded by Au, AgAu and AgNPs (UPF=4.6-4.9). Similar research on single jersey cotton fabrics reported UPF values below 15 with comparable machinery (Louris et al 2018). In contrast, the woven fabrics showed higher cover factors initially (18.8-19.9), which led to a more pronounced shielding effect.…”

“…One important feature of clothing is to protect human skin from excessive exposure to potentially dangerous UV radiation (Muthu 2017). A fabric's capability to shield UV light depends on the fiber type, garment structure, and color employed (Louris et al 2018). Moreover, additives such as noble metal nanoparticles or titanium oxide enable to alter its UV protection properties (Louris et al 2018;Tang et al 2015a;Vigneshwaran et al 2007;Tang et al 2014;Zheng et al 2013).…”

With UPFs lower than 5, most summer clothing is an insufficient barrier to sunlight (Gambichler et al 2001).…”

The textile materials functionalized with nanostructures have proven to be useful for many applications, such as antimicrobial, ultraviolet (UV) light protection, and self-cleaning substrates. The objective of this research is to synthesize and characterize zinc oxide (ZnO) nanoparticles (NPs) for the applications of UV absorbers and antibacterial activities. ZnO NPs were synthesized at different temperatures and reaction media of water (S-1) and 1,2-ethanediol (S-2) using precipitation and in situ methods on the surface of cotton fabric. The average crystalline size of the ZnO NPs estimated from the Debye Scherrer formula was found to be 32 and 26 nm for S-1 and S-2, respectively. The morphology of ZnO NPs characterized by scanning electron microscope revealed that agglomerated nanostructures were homogeneously formed on the fabric surface for S-1 and S-2; on the other hand, bundle-/flower-like particles having different sizes were observed for synthesis using an in situ method. The UV protection ability of ZnO NPs coated on textiles was investigated using UV-Vis spectroscopy by measuring the UV protection factor (UPF) in the range of 280–400 nm. Higher values of UPF were obtained for ZnO NPs prepared using an in situ method. The UPF value obtained by this method was found to be 320, which demonstrates its excellent ability to block UV radiation. The antibacterial activities of ZnO NPs synthesized by the two methods possess very good bacteriostatic activity against Staphylococcus aureus and Escherichia coli bacteria demonstrated by the zone of inhibition.

The present research develops a novel in-situ synthesis method to produce a high performance nanocomposite coating on polyethylene terephthalate (PET) fabric as an enhanced UV-protective textile. Reduced graphene oxide-silver (rGO-Ag) multi-layer nanocomposite was in-situ synthesized on the PET fabric through the direct redox reaction between the Ag + ions and GO sheets by using ultrasonic and thermal treatment. The X-ray diffraction and field emission scanning electron microscope confirmed that the well-synthesized Ag nanoparticles (AgNPs) loaded on PET fabric in presence of the GO sheets by using ultrasonic waves without reducing and capping agents. In this research, GO sheets were used as reducing and capping agents along with the ultrasonic treatment at low temperature condition. The final average size of the synthesized AgNPs in solution, on the PET surface and in the freestanding film is lower than 100 nm. The ultraviolet protection factor (UPF) of the PET fabric incorporating multi-layer rGO-Ag nanocomposite as a UV blocking system could reach to 6145.66, up to the 183-fold higher than uncoated PET fabric (UPF 33.63). In addition, the final fabric demonstrates a good air permeability and antibacterial properties due to the effective coating of rGO-Ag nanocomposite on PET surface.
