Simultaneous chemical modification and functional finishing of polyester textiles

Purpose This study aims to study the simultaneous treatment of polyethylene terephthalate (PET) fabric with sodium hydroxide (NaOH) and TiO2 nanoparticles (NPs). Design/methodology/approach PET fabrics loaded by TiO2 NPs were investigated by the use of scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and Fourier transformed infrared spectroscopy (FT-IR). Factors affecting the finishing process such as NaOH and TiO2 NPs concentrations, finishing duration and temperature were discussed. Findings The finished PET fabrics imparted new properties such as antimicrobial and ultraviolet protection factor protection, what is undoubtedly will increase the spread of this type of fabric and its use in new areas. Research limitations/implications The method used mainly depends on activating the surface of PET fabrics by a chemical method, specifically NaOH to cause partial decomposition, which may lead to an environmental impact. Practical implications The obtained results revealed that the simultaneous treatment of PET fabric with NaOH and TiO2 NPs showed antimicrobial and UV protection properties. They exhibited a strong antimicrobial activity and UV protection efficiency even after five washing cycles, indicating excellent laundering durability. Originality/value The approach has simplicity and implementability on an industrial scale without cost investment.
