Abstract: In part (1) wool was printed using 50g/kg urea instead of 200g/kg with combination of 20g/kg yeast enzyme and 150g/kg ethylene glycol. In this paper a completely elimination of urea from the printing paste was achieved. The sponge printing film which was formed on the surface of the wool fabrics, contained reactive dye, yeast enzyme, two different types of wetting agents and formic acid. The K/S of the printed samples was increased by about 60.55 % for red dye and 55.34 % for blue dye which were applied, when comparing with those printed with the traditional printing paste that containing 200g/kg urea.
