Silica Precursor for Improving Flame Retardancy of Cotton Treated With Urea/Ammonium Polyphosphate

The cotton and its blends is the most commonly used textile material in the design and production of protective clothing. However, as the cellulose textiles are the most flammable materials it is necessary to improve its flame retardancy. The government regulations have been the driving force for developing durable flame retardants finishes for textile, to improve its performance and to reduce the negative impact on the environment. Therefore, this paper investigates the effect of silica precursor (tetraethoxysilane - TEOS) added in bath with conventional flame retardant urea/ammonium polyphosphate for achieving environmental-friendly cotton flame retardancy. Silica precursors have excellent thermal stability and high heat resistance with very limited release of toxic gases during the thermal decomposition. Thermal properties of treated cotton fabrics were determined by Limiting Oxygen Index (LOI), thermogravimetric analysis (TGA) and Microscale Combustion Calorimeter (MCC).
