Interpretive Summary: In our research we have chosen to use mono- and di-substituted diethyl-2-aminoethylphosphonate derivatives of cyanuric chloride as a covalent linker with bleached and mercerized cotton. The choice of cyanuric chloride stems from its affordability and long time use in the cotton industry as a reactive dye linker. Utilizing the existing linker chemistry between cyanuric chloride and cotton, our synthetic strategy is to derivitise cyanuric chloride with flame retardant properties in a similar manner as has been done for many years with dyes.
In a series of experiments, two cyanuric chloride derivatives were synthesized in good yields and analyzed by 1H, 13C, and 31P nuclear magnetic resonance spectroscopy as well as high performance liquid and gas chromatography-mass spectroscopy. Cotton fabric was treated with these compounds and tested for flame retardant properties using standardized thermogravimetric, limiting oxygen index, and vertical flame methods. Scanning electron microscopy images of burned fabric reveal the extent of flame retardant protection. The results are reported herein and indicate cyanuric chloride derivatives have a potential use in flame retardant applications to cotton textiles.
