ABSTRACT:
The flame retardant according to the present invention is prepared by complexing a flame retardant polyphosphate compound with a silicone resin. The silicone resin is applied to cover the particles of the polyphosphate compound. As the polyphosphate compound, it is preferred to use ammonium polyphosphate having a weight average polymerisation degree of 20 to 2000. By applying the flame retardant of the present invention on fibers as a flame retardant resin composition containing a binder resin, environmentally soft flame retardant textile products can be stably obtained.
