The main objective of this work is to impart UV protection properties to cotton and cotton/polyester fabrics and enhance the original chemical and physical properties. In this procedure, the fabrics were coated with nanocomposites based on poly(vinyl alcohol)/plasticized starch (PVA/PLST (80/20%)/Zn NPs. The coated fabrics were then exposed to gamma radiation to induce cross-linked layer structure covering the fibers of the fabrics. The formation of Zn NPs was confirmed by UV/Vis and XRD analysis. In addition, the coated fabrics were characterized by the measurements of water absorption, crease recovery, thermal stability, surface morphology and tensile mechanical measurements. The UV protection of the coated fabrics was determined. The results indicated that the coated fabrics showed highly reducing UV-A, UV-B and ultraviolet protection factor (UPF), particularly with increasing irradiation dose, regardless of fabric kind. It was found that cotton and cotton/PET fabrics treated with PVA/PLST/Zn NPs nanocomposites irradiated to a dose of 30 kGy displayed UPF excellent rating values of 44.31 and 58.23, respectively.
