Abstract |
The flame-retardant (FR) treatments of wool fibers using Hexafluorozirconate/
titanate salts and tetrabromophthalic anhydride can cause skin irritation and gas toxicity
due to Zr and Br compounds respectively. A water-soluble polyfunctional cyclophosphazene
derivative, synthesized through substitution reaction of Hexachloro cyclophosphazene
and N-[3-(Dimethylamino)propyl] metacrylamide, was applied as a durable
flame-retardant for wool fabrics. Also, a crosslinked structure was introduced to improve
washing durability of the FR-wool, up to 10 laundering cycles, using
Acrylamide(AAm) and Triacryloylhexahydrotriazine (TAHT) as a comonomer and a
crosslinker respectively. The mole ratios of the TAHT and AAm concentrations compared
to the Dichloro tetrakis{N-[3-(Dimethylamino)propyl]methacrylamido} cyclcophosphazene
(DCTDCP) were optimized to 1.33 and 7.5 respectively. In addition, the pyrolysis
and combustion properties of the FR wool were assessed using LOI, TGA and
microcalorimetry suggesting a solid-phase FR mechanism. |
