The effects of N–methylol finishing treatments on the flammability of a range of polyester–cotton blends treated with a flame retardant, namely diammonium hydrogen orthophosphate (DAP), are reported. Of the three resin systems studied only urea–formaldehyde (UF) in the UF–DAP–treated fabrics gives rise to nitrogen–phosphorus (N–P) synergism. The mechanism for N–P synergism in this treatment is shown to depend on a dual phase or (1–*2) Inter Step mode of flame inhibition.
