Abstract |
In this study, the effect on flame retardancy and various physical properties
when TiO2 was added with a citric acid/phosphate complex acid catalyst together with
Pyrovatex CP new (N-methylol dimethylphosphonopropionamide), a phosphorus-based
flame retardant, was studied on cotton fibers. SEM-EDS analysis was performed to
confirm the surface characteristics and surface element analysis of the flame-retardant
treated cotton fibers, and a vertical carbonization test was performed to confirm the
char formation capability and flame retardancy according to the phosphoric acid ratio.
By comparing the LOI index before and after washing 10 times, the washing
durability of the flame retardant solution containing the phosphoric acid catalyst and
TiO2 was tested by LOI index after ten washing cycles. In addition, the influence of
the flame-retardant processing on the physical properties were compared including
thermogravimetric analysis (TGA), tear strength and whiteness. |
