Cotton fabric was treated with pure silica sol and boron doped partner through sol-gel method in order to improve its thermal and combustion properties. The results of thermo-gravimetric analysis, micro combustion calorimeter, and smoke density test of control showed that the finished cotton fabric had excellent thermal stability and mild combustion behavior with lower heat release rate. Furthermore, the smoke density test also indicated the safety performance of the boron doped silica sol treated cotton fabric in the fire.
