Abstract |
Large amount of formaldehyde could be released inevitably during the
flame-retardant (FR) treatments or from the finished fabrics using Provatex reagent and
Proban polymers which have been used as durable FRs for cotton. 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. |
