Synthetic Indigo Vat Dye
Use On...
Cotton, linen, rayon, silk or wool.
About Them...
Indigo belongs to a class of dyes called vat dyes, one or the oldest natural colouring substances used for textiles. Until the beginning of this century Indigo could be obtained only from plants.
Synthetic Indigo is a fine powder, it is much stronger than in the natural form. It is easier to use and yields predictable results.
How They Work...
Vat dyeing is an immersion method. The fabric is dipped into the vat dye bath for 2 to 3 minutes, rinsed, then left for approximately 15 minutes to oxidize, become blue. The immersion and
oxidization of the fabric is repeated until the desired depth of blue is achieved. Unlike other dye baths the Indigo vat may be saved, added to and reused many times.
