Abstract
Surface modification is a special feature in the textile industry. The end use performance of a textile product is greatly influenced by its final properties. A new concept has been developed based on the ‘lotus leaf’ principle, namely, ‘self cleaning textiles’, i.e. textile surfaces that can clean themselves, without any washing process. The use of superfine materials made by means of nanotechnologies has received attention in the process of finishing textiles in recent years. Nanomaterials or nanoscale nanomaterials are used to endow textiles with various properties, such as radiation resistance, antimicrobial properties, self-cleaning, amortization, and others. In this study, titanium dioxide nanoparticles were simultaneously sono-synthesized and coated onto cotton fabric. For the synthesis of titanium dioxide nanoparticles, two different precursors, namely, titanium isopoxide (TTIP) and titanium butoxide (TTIB) have been used. Several analytical methods, including field emission scanning electron microscopy (FESEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), dynamic light scattering (DLS), ultraviolet visible (UV-Vis) spectroscopy, were used to confirm the presence of TiO2 nanoparticles and investigate the self-cleaning property of treated fabrics.
