Abstract
A process for making a pattern according to intended design on cloth or clothing, particularly denim clothing, dyed with a colorant or a dye through decolorizing is provided. Fabric or clothing dyed with a colorant or a dye is impregnated with a substance forming an oxidized active species upon electrolysis and inserted between a pair of electrodes, and electricity is applied to the electrodes, whereby only a part where electricity is applied is selectively decolorized to make a pattern with gradated effect.
