In this article, the deposition of TiO 2 on cotton fabric using sol–gel technique has been described. Various process routes (pad‐dry‐cure, pad‐dry‐hydrothermal and pad‐dry‐solvothermal) were examined to impart a stable coating of TiO 2 on fabric. The role of precursor concentration, process temperature and time of treatment were studied to aim at a wash durable, UV protective and self‐cleaning property in the treated fabric. EDX and ICP‐MS techniques were used to examine the add‐on percentage of TiO 2 on cotton fabrics treated via different routes. It has been found that the TiO 2 remains largely amorphous and nondurable if it is given a short thermal treatment. To convert the deposited TiO 2 to its anatase crystal form, a prolonged hydrothermal treatment for at least 3 h needs to be given. TiO 2 deposition levels of less than 0.1% were found to be effective in imparting reasonable degree of UV protection and self‐cleaning property to the cotton fabric. The self‐cleaning ability of the treated fabric against coffee stain was also studied and was found to be related to the process route and the deposition levels of TiO 2 .
