Discharge Printing
Discharge Printing
Discharging is the process of removing dye by altering or breaking down the dye’s chromophores using chemicals or bleach.
Discharging can be combined with other techniques to create more intricate designs, such as over-dyeing with different colors or adding layers of paint, printing, or stenciling with opaque fabric paints like Lumiere, Neopaque, and Setacolor. It can also be used to correct dyeing mistakes. In essence, discharging is a creative way to produce one-of-a-kind fabrics for quilting or clothing.
