Technical Abstract: Herein we present the synthesis and the application of the triazine derivatives as flame retardant on cotton. Novel phosphorus-nitrogen containing compounds (TPN1, TPN2, TPN3 and TPN4) were prepared by organic reactions of cyanuric chloride and phosphonates. They were characterized by analytical tools such as proton (1H) and carbon (13C) nuclear magnetic resonance (NMR) spectroscopy and elemental analysis (EA). Cotton twill fabrics were soaked in 10-20% aqueous sodium hydroxide and then treated with TPN1-TPN4 which P, N - containing compounds in various organic solvent mixtures. The compounds were grafted onto the fabric by traditional pad, dry, cure methods to produce semi-durable flame resistance. Thermogravimetric analysis (TGA) will provide degradation and char content information of all materials by measuring the change in mass as a function of rising temperature. Treated fabrics were evaluated for flame resistance by such methods as vertical (ASTM D6413-08), 45º angle flammability test (ASTM D1230-01) and limiting oxygen index (LOI, ASTM D2863-09).
