In this work, we investigated the effect of nano aluminum tetraborate [Al2(B4O7)3] as a flameretardant
coating on the flammability of cellulosic fibers. The Al2(B4O7)3 with less than 100 nm in size, have been found to form a continuous and dispersed particles on the fiber surface which shows efficient
flame-retardancy properties. The optimum loading to impart flame-retardancy was about 2.60%. Thermogravimetric analysis (TGA) of pure and treated fibers was accomplished and their thermograms were compared and commented. The results obtained are in favor of the coating theory and also dust or wall effect theory.
