A large number of new fabrics have emerged continuously, and the quality and quality of fabrics have even tended to the international leading level. An important trend in the production of new fabrics is that textile fabrics are not only satisfied with sensory comfort such as feel and appearance, but also pay more attention to the development of functionality. Functional textiles will further expand to fabrics in various fields, so it has become an important trend in the development of functional fabrics.

The development of functional fabrics depends to a large extent on the development of textile functional finishing agents and finishing technologies. Therefore, further exploration of the research and development of functional modifiers is the main direction for the development of functional fabrics. As a functional nanoparticle, TiO ₂ plays an important role in the finishing of fabrics. However, in order to further improve the effect of TiO ₂ on fabrics, it is necessary to further modify it.
