Remove Permanent Press Finish

Please read directions carefully before starting.

If your fabric is treated with a permanent press finish, you need to remove it prior to dyeing. This recipe treats 1 pound (454 gm) of fiber. It is important to work in a well-ventilated area and use gloves, safety glasses and a cartridge respirator fitted with an acid gas cartridge. Always do test samples before working on a large project. For additional information visit our web site at www.prochemical.com.

• Use extra caution when using this procedure.
• Wear rubber gloves, apron, or old clothes and cover work area with newspapers.
• Dye utensils should never be used for food preparation.

Supplies
PRO Dye Activator or Soda Ash
Synthrapol
hydrochloric acid (muriatic acid 30%-35% strength)

Procedure
1. Scour the fabric by machine washing in HOT 140^oF (60^oC) water, or by hand in a pot on the stove with ½ tsp (2 gm) PRO Dye Activator and ½ tsp (2.5 ml) Synthrapol per pound of fabric (454 gm, or 3 to 4 yards cotton muslin, or 8 yards 8mm China Silk, or 3 Medium T-shirts, or 1 sweatshirt). 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. Make the bath. Measure 2 gallons (8 liters) of cool water into a non reactive stainless steel or enamel pot. Carefully add 1 Tbl (15 ml) hydrochloric (muriatic) acid.

3. Add the washed fabric and heat the bath to 185^oF (85^oC) with intermittent stirring for twenty minutes.

4. Rinse thoroughly in warm water and fabric is ready for a dye bath or it can be dried and dyed later.
