A water-soluble cyclophosphazene derivative was synthesized as an ecofriendly phosphorus-based FR for cotton fibers. Dichloro tetrakis{N-[3-(Dimethylamino)propyl]methacrylamido} cyclcophosphazene (DCTDCP) was synthesized through the substiutution reaction of Hexachloro cyclophosphazene and N-[3-(Dimethylamino)propyl] methacrylamide at a mole ratio of 1 : 4, which can be cured dually by both alkaline treatment and UV irradiation. More crosslinked networks were produced through the addition of Triacryloyl hexahydrotriazine and Acrylamide as a UV-curable crosslinker and a comonomer respectively. Both flame retardancy and washing durability of the FR cotton were improved synergistically. The durability improvement may be caused by the covalent bond formation of the FR with cellulose and the high degree of polymerization of DCTDCP, which can be verified by the pyrolysis and combustion behaviors analyzed by LOI, TGA, and microcalorimeter.
