A fabric of cellulosic fibers, particularly natural cellulosic fibers, of improved dyeability having a polymer of a monomer containing a quarternary amine group dispersed in the fibers with no phase separation is discharge printed. The improved cellulosic fibers can be prepared by impregnating a monomer containing a quarternary amine group into cellulosic fibers and polymerizing the monomer in the fibers. This treatment of cellulosic fibers with the polymer of a quarternary amine monomer can be advantageously utilized in the discharge printing of a fabric from a blend of hydrophobic synthetic/cellulosic fibers.
