The research aims at developing Eco-friendly flame retardant textile fabric using phosphorous based intumescence chemistry. Phosphorous in the structure of Spirocyclic pentaerythriol diphosphoryl chloride (SPDPC) acts as the main group to impart flame retardancy. Intermediate compounds were synthesized in the laboratory and finally converted into sol. The silane sol was applied to the textile material using pad-dry-cure method. The intermediate compounds and the coated material were tested using Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimeter (DSC), and Thermogravemetric analysis (TGA) testing instruments. Vertical flammability testing was performed as per ASTM D-6413 standards to test the fabric for its flame retardancy. Tensile testing of the coated fabric was performed as per ASTM D5035 standards. Change in thickness of the coated fabric was measured as per ASTM B499 test method. The research concludes that phosphorous based intumescence chemistry is effective in imparting flame retardancy to the cotton textile substrate. The change in tensile strength and thickness of coated textile substrate was found to be statistically significant.
