    In this study, the chemical modification of cotton fabric to develop UV-protective properties is presented. For this purpose, TiO2 and a three-component Ag/TiO2/g-C3N4 composite were synthesised ex-situ and were applied to cotton fabric using a pad–dry–cure method. The presence of the composite on the cotton fibres was detected using the SEM, EDS and FTIR methods and with a digital microscope. The results show that the application of TiO2 increased the UV protection of the cotton fabric compared with the untreated fabric. The combination of TiO2 with Ag and g-C3N4 in the composite further improved the UV protection of the cotton fabric, as the absorption in the UVA range increased significantly. This resulted in a large increase in the UPF value, placing the cotton fabric in the excellent protection category. This proves the cumulative effect of the components in the composite.

    Sustainable surface modification of textile with Ag-doped TiO2/polysiloxane nanocomposite for antibacterial, UV protection, and flame retardant properties
    (Wydawnictwo Politechniki Łódzkiej, 2022) Rashid, Mohammad Mamunur; Tomšič, Brigita; Simončič, Barbara; Jerman, Ivan; Štular, Danaja; Zorc, Matija
    In this work, a cotton fabric with advanced photocatalytic and flame retardant properties was developed by using Ag-doped TiO2 in combination with 3-(trihydroxysilyl)propyl methyl phosphonate (TPMP) with a sustainable sol-gel/hydrothermal approach. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS) were used to confirm the successful application of Ag-doped TiO2 and TPMP on the cotton fabric. The results of UPF, bacterial reduction against Escherichia coli and vertical flammability test showed that the creation of Ag-TiO2+TPMP nanocomposite on the surface of the fibres gave the cotton fabric superior antibacterial activity, very good UV protection and flame retardant activity.
