Beschreibung
Zusammenfassung:	The invention relates to a process for preparing a textile photocatalytic material. According to the invention, the process consists in functionalizing a textile substrate of woven fabric type made of cellulose and/or polyester or protein fibers by impregnation with a float which comprises 10...50% tetraethyl orthosilicate, 1...20% anchoring agent, 5...30% solvent, 0.5...5% titanium dioxide photocatalyst, 1...20 % modifying agent, 0.1...0.5% acid catalyst, 0.1...5% polymerization accelerator and 5...35% water, after which the impregnated textile support is dried at a temperature of 20...30°C and is heat-set at a temperature of 100...130°C for 30...90 min, resulting in a coated textile material with high physical and chemical, photochemical and thermal resistance and high photocatalytic activity.
