A novel kind of water soluble hyperbranched polymer, the amino terminated hyperbranched poly-amidoamine (HPAMAM - NH2) is synthesized by the Michael addition and melt polymerization of methyl acrylate (MA) and diethylenetriamine (DTA). HPAMAM is added to the selected ten kinds of water soluble dyes solution separately. The flocculated dye prevents the dye and fiber from combining, the removal of loose color and anti staining effect are achieved. Taking reactive orange K - GN as an example, satisfying anti staining result is achieved under the condition of pH value 5 - 6. with little dosage of HPAMAM (<10g/L) at 30 degrees C for 15 - 30 minutes.<
