Besides vat dyes, 2 chemicals: sodium hydroxide (lye) and thiourea dioxide or sodium hydrosulfite must be added to the dye bath to accomplish the discharge and color replacement. After dyeing, the fabric must be exposed to the air to oxidize. It's all worth it since the results can be breath-taking and fill your soul! Imagine removing color and adding entirely new color in selected areas simultaneously!!!
This Spring I put together a new collection of scarves with shibori using vat dye discharge in "to-dye-for" colors in luscious jade, apple, turquoise, orange and shocking pink. I used rubber bands, folded and clamped wooden blocks and braiding for resist. Some examples of my creative process follow. The first 2 images portray the "braided" method on silk charmeuse.
This scarf was first ground dyed with shades of raspberry and bronze and then vat dye discharged with turquoise - eye candy!
What lovely patterns, color and texture can be achieved using these methods!
This last example was dyed pale blue on silk crepe, banded and vat dye discharged with apple green, then "braided" and vat dye discharged in orange...
I buy vat dye products from both Pro Chemical and Dye in Somerset, MA (1-800-2-BUY-DYE)(www.prochemical.com ) and Aljo Mfg. Co. in New York, NY ( 212 966 4046).
