Basic Procion MX Directions for Immersion Dyeing:

Supplies:

  • PRO MX Dye Powder
  • PRO Dye Activator or Soda Ash
  • Synthrapol
  • Common Salt
  • Metaphos ( water softener): optional - use if you have hard water)

1. Scour the fabric by machine washing it in Very Hot 140 Degree water or by hand in a pot on the stove with 1/2 Teaspoon of Activator or Soda Ash and 1 teaspoon of Synthrapol per pound of fabric (3 medium T-Shirts). Rinse thoroughly. This step does not add the dye fixer to the fabric, it prepares your fabric for dyeing by removing any dirt, oil or sizing.

2.  Dissolve dye Powder.  Measure the desired amount of dye powder from the chart below in 2 cups room temp water and set aside.

 Here is a general chart for achieving desired saturation using Procion MX dyes.  For each pound of dry fabric or fiber use:    
Desired Saturation Pale
Medium Dark  Black  
Dye Powder 1tsp 3 tsp 6 tsp 12 tsp
Salt 1 lb 1.5 lb 2 lb 2 lb
Dye Activator 5 Tbl 5 Tbl 7 Tbl 7 Tbl

3.  Prepare dye bath.  Measure 2.5 Gallons of room temp water for every pound of fiber or fabric into a large plastic stainless steel enamel or non-reactive metal container.  Container should be large enough for the fabric to move freely and to stir the dye bath without spilling.    

4.  Add Salt (see above chart) and 1 tsp of Metaphos (only if you have hard water) to the dye bath and stir until mixed thoroughly and disolved.  Add dissolved dye and stir.  Add washed and damp fiber or fabric that you want to dye.  Stir continuously for even results for 10 to 15 minutes, or do not stir for mottled results.

5.  Completely dissolve Pro MX dye activator or Soda Ash from the reference chart above into 2 cups of warm water.  While wearing rubber gloves remove the fabric from dye bath and pour in the dissolved Pro Dye Activator or Soda Ash.  Give it a stir and return the fabric to the dye bath.  Stir continuously for the first 5 minutes.  Then give it a stir every 5 minutes for the next 60 minutes.  This will ensure maximum penetration from your dye and achieve the proper color shading.

Tip:  For even dye results make sure to stir constatly for the first 30 minutes of the dye bath.

Tip:  To achieve a Deep Black shade with Procion MX extend dyeing time to 90 minutes after adding your Activator or Soda Ash.

6.  Rinse and Wash.  After 60 Minutes (90 minutes for black), dyeing is complete.  Remove fabric fromt the dye bucket and pour the exhausted dye bath down your drain.  Rinse fabric thoroughly in a bucket of room temperature water.  Change the rinse water 3-4 times.  Then wash in Hot water adding a half teaspoon of Synthrapol per pound of fabric.  Rinse well and dry.  Dark colors might need a second Hot Synthrapol rinse. When the rinse water is clear you know the dye is finished rinsing and is set properly.

Note:  Dye baths cannot be stored or reused after you have added Activator or Soda Ash.

Note:  If you are getting blotchy inconsistent dyeing results make sure to dissolve your Procion dye powder completely.  Strain through a cheesecloth or other soft strainer if necessary to remove any little bits if it becomes a problem.  Dyestuff are made from various extracts and behave differently.

Note:  Make sure to use Non-iodized salt for a purist approach.
