The shoes are the necessities of daily life, The shoe material good self-cleaning properties will guarantee shoes clean, beautiful, and has a vital role to remove the odor, so the development of shoe materials with self-cleaning finishing agent has far-reaching significance and broadmarket prospects. This article focuses on the theoretical foundation of the fabric of the self-cleaning technology. In this paper, the self-cleaning technology include:

        1. Use and water repellent oil the finishing agent EX910E fabric finishing, fabric with water and oil repellent performance.

       2. Use of an organic fluorine-finishing agent to shape the surface of the water-repellent fabric of low surface tension, with the great specific surface area of ​​nanoparticles to improve the roughness factor to form a rough surface, in order to construct a suitable micro structure. Design by simulating the lotus effect, self-cleaning fabric treated with a nano.

      3. Play photocatalytic decomposition of organic matter characteristics of nanomaterials photocatalytic self-cleaning characteristics, developed a composite nano photocatalyst self-cleaning finishing agent. By orthogonal experiment to optimize the process to get the best shoe materials composed of self-cleaning finishing agent formulation and finishing process. Water-repellent and oil and lotus effect, self-cleaning fabrics water repellent performance reaches 9 7 oil repellent performance. The photocatalyst class self-cleaning fabrics showed good ability to degrade organic contaminants under UV light and sunlight. Oil and photocatalyst class combined with water-repellent and self-cleaning fabric characteristics, combined self-cleaning and water repellent oil and photocatalytic degradation of organic matter of double effect finishing agent. By using a silane coupling agent so that the nano TiO_2 dispersion stabilizer, and play a role in connection the Nanometer TiO_2 with organic fluorine finishing agent. For photocatalyst products standards lack the status quo, the establishment of a self-cleaning textiles testing methods. The experiments prove that the method is better characterize the performance of photocatalytic self-cleaning fabrics, basic and applied research and development of self-cleaning textiles has important theoretical and practical significance.
