| I stencilled this fabric. (Not all fabrics discharge to white). |
Discharging Is the fancy name for removing colour form dyed fabrics.
The regular household chlorine bleach works well on all cellulose fibres
(cotton, linen, rayon, bamboo etc), but will cause discolouring and deterioration
in most other natural fabrics. Not all dyed fabrics are in fact dischargeable -
it all depends on what kind of dyes have been used to dye the fabric originally.
If you dye your own fabrics, any fibre reactive dyes will discharge beautifully.
The variety of techniques you can use for discharging are almost endless.
In fact a lot of the tools that you use for adding colour to cloth can also be used
to remove colour!
Once the dark fabric has been discharged, you need to rinse and neutralize the
bleach - in order to stop the bleach from eating holes into your fabric.
The same goes for any tools you use - bleach is notorious for consuming brushes
unless they have synthetic bristles.

| On this fabric I used a brush to discharge the black. |
 |
| Pole wrapped and discharged to a lovely rich brown. |
 |
| I screen printed the discharge paste onto silk noile using Rongalite (which works on silk) instead of bleach. |
 |
| Colour Vie pigments do not discharge, but can be added afterward for layering and added surface details. www.colourvie.com |
 |
| For the black silk crepe de chine scarf I added colour Vie pure pigment to the Rongalite discharge paste, so that colour was added at the same time as the black silk was discharged. |
