In this paper, we studied the synthesis, characterization,
and
flammability of the water-soluble, nonhalogenated organophosphorus
flame retardant (FR) dimethyl-[1,3,5-(3,5-triacryloylhexahydro)triazinyl]-3-oxopropylphosphonate
for application to cotton fabrics by nonpolymeric network. The FR
was synthesized in a one-step reaction from dimethyl phosphite and
1,3,5-triacryloylhexahydro-1,3,5-triazine under mild conditions, and
its structure was fully characterized by 1H, 13C, and 31P nuclear magnetic resonance (NMR), mass spectrometry
(MS), and Fourier transform infrared spectroscopy (FT-IR). The finishing
conditions to achieve a covalent bond between the FR and fibers were
optimized, and the FR capability of the treated cotton was investigated
by limiting oxygen index (LOI), flame test, thermogravimetric analysis
(TGA), and micro cone calorimeter (MCC) tests. This study showed that
fabrics treated with the FR are effectively flame resistant, and the
FR property is enhanced by covalent bonding of the FR to fibers.
