BLEACH THICKENER
 
The Bleach Thickener is designed to be used with bleach and water to produce a thickened paste
which can be applied to fabric in order to remove color. The paste can be painted or printed
onto the fabric. The thickener remains stable in bleach for 24 to 36 hours. The bleach
thickener is for use on cellulose fibers such as cotton, linen, and rayon. Not recommended for
protein fibers such as wool and silk.
 
To mix a solution for painting or printing the following ratios work well.
 
  • Solution for Painting:
  • 10% thickener to water
  • 20% bleach to water

  • Sample Recipe:
  • 125ml or appr.1/2 cup water
  • 12grams or appr.1 Tablespoons thickener
  • 25 ml or between 1/16 to 1/8 cup bleach
     
  • Screen or Block Printing Solution:
  • 20% thickener to water
  • 30% bleach to water
     
  • Sample Recipe:
  • 125 ml or appr. 1/2 cup water
  • 25grams or appr.1 tablespoons + 2 teaspoons thickener
  • 37ml or appr. 1/8 cup bleach

Following the percentages above add bleach thickener to water. Mix in a blender until mixture
is a smooth, thick and even consistency. To this mixture add your bleach, blending in till
smooth. Note that the mixture will be very thick until the bleach is added, which will thin out
the mixture to an applicable consistency.
 
Paint or print this mixture onto fabric which has been previously dyed. Leave to dry. The
longer that the mixture is left on the fabric and the thicker the application of the bleach paste, the
more dye that will be removed. However do not leave on for longer then several hours as the
bleach may weaken the fabric. Once dry or discharged to taste, rinse, then soak in Bleach Stop
or something to deactivate the bleach, then wash fabric to remove thickener.
 
When using the bleach thickener on dyed fabrics you will find various results depending on the
type of dye and color that is chosen for the background. We recommend our Procion MX
dyes for cellulose fibers. Many dyes will not discharge to a white but rather to a lighter
version of the same color and sometimes to another color entirely. Some colors and dye types will
not discharge at all or very little. Results may vary. A little experimenting is required!
