Abstract :A potential flame retardant phytic acid (PA) was applied to wool fabric together with acid metal complex dyes in order to prepare  coloured and flame retardant textile materials, and the dyeing properties of the dyes and the flame retardant effect of PA on wool fabric  were studied. The treated wool fabrics exhibited much higher flame retardancy than pure wool fabric according to limiting oxygen index  and vertical burning tests. The thermal stability of wool fabrics was assessed by thermogravimetric analysis, and the results  demonstrated that the flame retardant mechanism of the treated wool fabrics involves a significant condensed-phase activity. Despite the  competitive effect of the adsorption between PA and the dyes on wool, it is feasible to apply PA and acid metal complex dyes to wool in  one bath.
