In recent years attention has been towards the development of smart textiles with superior characteristics and enhanced durability. To cater the needs of high sustainable textiles, application of nanotechnology has been introduced in textile industry with promising achievement. Titanium oxide nanoparticle is one such material which could be applicable in textile industry, whose photo-catalytic activities have been widely investigated owning to its high stability and low toxicity. This paper enlists various applicative properties of titanium oxide nanoparticles and its implementation in the textile industry, especially to woollen fibres for advanced applications.
