Abstract
The flame retardant behavior of cotton fabric treated with phosphorusnitrogen containing triazine compound was evaluated It was found that cyanuric chloride 246trichloro135triazine is an excellent starting material for the preparation of phosphonate flame retardants that interact well with cotton to improve flame resistance FR performance Tetraethyl 6chloro135triazine24diyldiphosphonate TECTDP has been prepared by a simple onestep reaction in high yield 980 Cotton fabrics treated with TECTDP result in covalent bond formation between TECTDP and hydroxyl groups in cotton fabrics This FR system provides an efficient flame retardant for cotton textiles at low cost to meet government mandates In this study the FR material was synthesized and characterized by 1H and 13C nuclear magnetic resonance NMR and LCMS spectroscopy The chemical structure of cotton twill fabric treated with TECTDP by paddrycure method was analyzed by FTMIR and SEM Furthermore the thermal and flammability properties were evaluated by thermogravimetric analysis TGA limiting oxygen index LOI ASTM D286309 and a vertical flame test ASTM D641308
