The chemical resist process allows you to control background coloring
of printing (and other methods of direct application) without the need
for additional silk-screens and without color overlays. The process takes
advantage of differing reactivity levels of Remazol and Cibacron F reactive
dyes (similar results can be obtained with Remazol and Procion MX reactive
dyes). Since some colors of dye work more effectively with this process than
others, thorough testing is necessary in order to achieve predictable results.
Chemical Resist Agent
The amount of chemical resist agent needed in the reactive dyes is
dependent upon the strength of the Remazol dyes used (see chart).
Dye Activator Options
This process works best with soda ash as the activator in the reactive
dye pastes and fixing agent FRP as the activator in the Remazol dye pastes.
It will not work with the soda soak/batching method for fixing the dye.
It will work with baking soda as the activator for the remazols, but not
always reliable. (With baking soda as the activator, it is critical for
remazols to dry slowly; in midwinter in Michigan, it may be necessary to
prolong their dampness in fabric by batching them in plastic for 24 hours).
Remazol Under Reactive Dyes
- Mix thin Remazol dye pastes with the appropriate amount of
dye activator (see chart).
- Apply Remazol dyes as desired. Allow them to dry naturally
- Mix reactive dye pastes with the appropriate amounts of chemical
resist agent and soda ash (see chart).
- Apply reactive dyes. Allow them to dry naturally.
- Wrap fabric in paper, tie, and steam for 8-12 minutes.
- Wash out excess dye and then boil the fabric for minutes to achieve
the full chemical resist effect. Use a drop of Synthrapol in the rinse
water and in the water to be boiled.
- Little or no halo effect should occur around reactive dye areas
using this method.
