In this two-bath method, first, a polyester / nylon blended product is dyed with a disperse dye for polyester in the first bath, and then treated with an alkali reducing bath to remove the disperse dye adhering to the nylon fiber. It is a method of dyeing nylon fibers so as to match polyester fibers with an acid dye for nylon in the bath. However, dyeing by such a two-bath method is complicated, requires a long time, is not easy in toning, and has poor wash fastness.

After dyeing the nylon blended product with a dyeing bath containing a disperse dye for ordinary polyester and an acid dye for nylon, reduction treatment is performed in the acid reducing bath as described above to dye the polyester fiber with the disperse dye. On the other hand, since the disperse dye attached to the nylon fiber is substantially completely removed and the dye is dyed with an acid dye, a polyester / nylon blended article having excellent washing fastness can be obtained by the one-bath method.
