This leveling procedure can often correct unlevel dyeings without the need for stripping and subsequent redyeing.
Set bath at 120F with 0.5% owg "Tanaterge" D-6, 3% owg "Migrassist" AC/3% owg "Tanapal" CAL (or 6% "Migrassist" AC) and 20% Glaubers salt.
Add acetic acid to pH 4.0. Heat to the boil and hold for 2 hours. Where pressure equipment is available, more rapid and more complete leveling may be obtained at 225F.
