Immersion Dyeing Acrylic
using PROsperse Disperse Dyes

Please read the directions carefully before starting.

PROsperse Disperse Dyes produce only light colors on Acrylic fabrics. Acrylic dyes at a boil, but exhaustion is slow and there is not good build up for darker shades. Expect only pale to medium shades. All dyeing should be done in a stainless steel or enamelware container only; never use an aluminum pot. Use Pyrex or stainless steel measuring utensils and a large wooden dowel for stirring in the boiling dye bath. Always do test samples before working on a large project. For additional information, visit our web site at www.prochemical.com.

Supplies
PROsperse Disperse Dye
Citric Acid or White Distilled Vinegar
Synthrapol
PRO Dye Activator or Soda Ash

Procedure
1. Scour the fabric
by machine washing in HOT 140oF (60oC) water, or by hand in a pot on the stove with ½ tsp (2 gm) PRO Dye Activator or Soda Ash and ½ tsp (2.5 ml) Synthrapol per pound of fabric (454 gm, or 3 to 4 yards of muslin weight fabric). Rinse thoroughly. This step does not add the dye fixative to the fabric; it prepares your fabric for dyeing by removing any dirt, oil or sizing.

2. Dissolve the dye. Thoroughly dissolve the desired amount of dye powder, from the chart below, in 1 cup (250 ml) of boiling water. Let mixture cool to room temperature and stir well again. Before adding to dye bath, strain it through two layers of old nylon stockings.

Dye Powder ½ tsp (1.3 gm) 1½ tsp (3.8 gm)
Water 2½ gallons (10 liters) 2½ gallons (10 liters)

Citric Acid  or Vinegar 1/8 tsp (0.6 ml)
or 1¼ tsp (6.25 ml)
1/8 tsp (0.6 ml)
or 1¼ tsp (6.25 ml)

3. Prepare the dye bath. Measure warm 100o to 105oF (38o to 41oC) water into a non-reactive, stainless steel or enamel pot. Add your dissolved and strained dye and stir well. Add Synthrapol and Citric Acid or White Distilled Vinegar, allowing sufficient time for each to become well distributed before adding the next. Stir well and add your damp, scoured fabric.

4. Slowly increase the heat while constantly stirring fabric, raising the temperature to a boil over 30-40 minutes.

5. Stir intermittently and gently for 40 to 60 minutes, to prevent the fabric from creasing or distorting.

6. Remove from the heat and allow the dye bath to cool to below 150oF (66oC).

7. After the dye bath cools to 150oF (66oC), rapidly cool fabric by allowing cool water to run into dye pot.

8. Rinse well, extract excess water and dry the fabric.
