Discharge Dyeing

 Discharge is the process of chemically removing color from previously dyed fabric. Because not all dyes will discharge in the same way, (and some won't discharge at all) you need to do a small-scale test with the discharging agent before purchasing commercial fabric.
Heather gave a class on discharge dyeing last Friday. It was a great deal of fun.

 Sample fabric where we tested different techniques.

 Once bleaching is complete, the fabric must be neutralized to stop the corrosive action of the bleach and then rinsed.
