In this paper, a flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate (DMMEP) was applied onto wool fabrics by graft copolymerization technique in water media. The paper discussed the technological conditions of the formation of wool-g-DMMEP such as the pH value of reaction, reaction temperature and time etc. The weight gain of wool fabrics was chosen to be the indicator of optimized technological condition. The results showed that DMMEP treated wool fabrics have high limiting oxygen index(LOI). Wool fabric with weight gain 4.27% has high LOI 34.6%, which is hard ignited in air. Char residues of DMMEP treated wool fabrics are more rigid and solid.
