for added visual dimension. For additional information visit our web site at www.prochemical.com.
Supplies Procedure
PRO H-Reactive Dye (powder or liquid)
Urea
PRO Chem Flakes
Synthrapol
Metaphos (optional, but use if you have hard water)
PRO Dye Activator or Soda Ash or Baking Soda (Sodium Bicarbonate) or PRO Fix LHF
PRO Print Paste Mix SH (Cotton)
or PRO Print Paste Mix F (silk)
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 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 Print Paste. Measure 5½ Tbl (55 gm) PRO Print Paste Mix SH or F into a dry container. Measure 1 cup (250 ml) of warm 110oF (44oC) water into a container. Measure 3/4 tsp (2 gm) of PRO Chem Flakes and add it to the warm water; stir until dissolved. Add measured PRO Print Paste Mix to the water while stirring rapidly. Continue stirring until you obtain a smooth paste. Let paste stand 1 hour or overnight for smoothest results. Unused paste should be kept in a closed container. Store prepared print paste without dye up to six months.
3. Make the H-Urea Water by mixing together the ingredients below. Allow H-Urea Water to cool to room temperature before using. Store unused H-Urea Water at room temperature in a closed container. Discard it if you detect an ammonia smell.
9 level Tbl (100 g) Urea
1 level Tbl (8 gm) PRO Chem Flakes
1 level tsp (7 gm) Metaphos (optional, but use if you have hard water)
1 quart (1 liter) warm 110oF (44oC) water
4. Make the Dye Paint. The Dye Paint thickness described below is a guideline. Experiment until you get the thickness that suits your application needs.
Hand Painting (thin paint)
Dye Powder: Thoroughly dissolve the desired amount of dye powder, from the following chart, with just enough H-Urea Water to make a lump free paste (approximately ¼ cup or 60 ml). Thicken with prepared Print Paste, usually 1 to 2 tsp (5 to 10 ml), then add H-Urea Water to make 1 cup (250 ml). Stir until thoroughly mixed.
Liquid Dye: Measure the desired amount of liquid dye, from the chart below, into a 1 cup (250 ml) container. Thicken with prepared Print Paste, usually 1 to 2 tsp (5 to 10 ml), then add H-Urea Water to make 1 cup (250 ml). Stir until thoroughly mixed.
Screen printing, Block printing, and Stenciling (thick paint)
Dye Powder: Thoroughly dissolve the desired amount of dye powder, from the following chart, with just enough H-Urea Water to make a lump free paste (approximately ¼ cup or 60 ml). Add prepared Print Paste to make 1 cup (250 ml). Stir until thoroughly mixed.
Liquid Dye: Measure the desired amount of liquid dye, from the chart below into a 1 cup (250 ml) container. Add prepared Print Paste to make 1 cup (250 ml). Stir until thoroughly mixed.
For each cup of Dye Paint, use the amount listed below of PRO H-Reactive Dye (powder or liquid) for the desired shade.

| 40% Liquid Dye | 1 tsp (5 ml) | 3 tsp (15 ml) | 6 tsp (30 ml) | 12 tsp (60 ml) |
5. Add fixative to the Dye Paint. Please read the three methods below then choose the one that best suits your application needs.
Method #1 PRO Dye Activator or Soda Ash
Just before applying the dye paint to the fabric dissolve 1 tsp (4 gm) of PRO Dye Activator or Soda Ash in each 1 cup (250 ml) measure of dye paint. Stir until it is thoroughly mixed. Apply dye paint to the fabric.
Set Dye: Allow patterned fabric to air dry, and set dye with steam or dry heat as outlined below.
Shelf Life: Dye paint with PRO Dye Activator or Soda Ash may be stored for one month in a cool dark place without color loss.
Method #2 Baking Soda
Just before applying the dye paint to the fabric dissolve 1 tsp (4 gm) of Baking Soda in each 1 cup (250 ml) measure of dye paint. Stir until it is thoroughly mixed. Apply dye paint to the fabric.
Set Dye: Allow patterned fabric to air dry, and set dye with steam or dry heat as outlined below.
Shelf Life: Dye paint with Baking Soda may be stored with baking soda fixative for 2 months in a cool dark place without color loss.
Method #3 PRO Fix LHF
Print or paint fabric without adding Baking Soda or PRO Dye Activator or Soda Ash to your dye paint.
Set Dye: Allow patterned fabric to air dry thoroughly, and set with LHF as outlined below.
Shelf Life: Dye paint may be stored for 2 months in a cool dark place without color loss.
6. Set the dye. Please read the dye setting methods below then choose the one that best suits your application needs.
Steaming
Loosely roll the fabric, jelly roll fashion, in between a piece of muslin, blank newsprint, or non fusible pellon, so patterned surface does not come in contact with itself. Then roll the tube lengthwise, like a cinnamon roll, and tie loosely to secure the shape. Place the rolled fabric in the steamer and steam for 30 minutes. Add more boiling water as needed.
Dry Heat
Not recommended for viscose rayon or silk.
Clothes Dryer: Air dry patterned fabric then cure in a clothes dryer on the HOTTEST setting for 45 minutes.
Bake: Prepare fabric as for steaming and bake in oven 5 minutes at 300oF.
PRO Fix LHF
Pour PRO Fix LHF into shallow pan or container. Using a wide soft brush or paint roller, apply LHF to the right side (patterned side) of the fabric. Use a minimum of brush strokes to avoid smearing your design. Let LHF dry a little bit then cover your fabric with plastic and cure for at least 24 hours. Room temperature must be above 70oF (22oC). We've found that the warmer the cure temperature, the darker the final color. LHF can also be steam set. Prepare fabric as outlined for steaming. Make sure PRO Fix LHF is completely dry before rolling the fabric.
7. Rinse the fabric. After setting the dye, rinse fabric thoroughly in a bucket of room temperature 75o to 95oF (24o to 35oC) water. Change the water 3 to 4 times. Then wash with very HOT 140oF (60oC) water adding ½ tsp (2 ml) Synthrapol per pound (454 gm) of fabric. Rinse well and dry. Black and very dark colors may need a second HOT Synthrapol wash.
