Supplies

WashFast Acid Dye
Print Paste Mix F
Synthrapol
Ammonium Sulfate
PRO Dye Activator or Soda Ash

Procedure

1. Scour the fabric (for silk only; skip this step if you’re dyeing woven wool) by machine washing in HOT 140EF (60EC) 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 8 yards 8mm China Silk). Rinse thoroughly, dry and iron as necessary.

2. Make the Thickener Paste. Measure 5½ Tbl (55 gm) PRO Print Paste Mix F into a dry container. Measure 1 cup (250 ml) of warm 110EF (44EC) water into another container. Add measured PRO Print Paste Mix F 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. Dissolve the dye. Decide if you want a pale, medium or dark value. Measure the dye powder amount, according to the chart on the next page, into a clean dry 1 cup (250 ml) measure. Dissolve the dye powder with ½ cup (125 ml) of boiling water and set aside until cool. Add ¼ tsp (1.25 ml) of Synthrapol to the dissolved dye. Then add 1½ tsp (9.5 gm) of Ammonium Sulfate and stir thoroughly.

	Pale	Medium	Dark	Black
Dye powder	½ tsp (1 gm)	1¼ tsp (3 gm)	2½ tsp (6 gm)	6 tsp (15 gm)

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)

Thicken the dissolved dye with the prepared Print Paste, usually 1 to 2 tsp (5 to 10 ml), then add water to make 1 cup (250 ml). Stir until thoroughly mixed.

Screen printing, Block printing, and Stenciling (thick paint)
Add enough prepared Print Paste to the dissolved dye to make 1 cup (250 ml). Stir until thoroughly mixed.

5. Apply the dye paint. Paint or print the fabric. After the fabric is dry, then you are ready to steam.

NOTE: Leftover dissolved dye can be stored for a minimum of 6 months.

6. Set the dye using the canning kettle method.

The pot or canning kettle must be deep enough to hold the wrapped fabric and wide enough so that the fabric bundle does not touch the sides of the pot. Invert the wire basket or bottle rack and place it in the bottom of the kettle. This serves as a platform for the bundled fabric to rest.

Make sure your painted or printed fabric is dry. Loosely roll the fabric, jelly roll fashion, in between a piece of muslin, cotton sheeting, pellon, blank newsprint, or kraft paper, so the patterned surface does not come in contact with itself. Then roll the tube lengthwise, like a cinnamon roll, and loosely tie it to secure this shape.

Place the fabric bundle on top of the inverted wire basket. Wrap a towel around the lid of the canner to absorb condensed steam. This protects the fabric bundle from droplets of water falling back onto the bundle, which causes bleeding of the dyes.

Put water in the bottom of the steamer. Make sure the water is up to, but does not touch the bottom of the wire platform where the fabric bundle sits. Turn on the heat and once the water is boiling and is producing a good head of steam, place the bundle in the kettle. Set the timer for 30 minutes for pale shades and up to 60 minutes for black or dark shades. Check the amount of water periodically and add boiling water as necessary. The steam time also varies depending upon the dye, and the type and weight of the fiber.

7. Rinse the fabric. Let the steamed fabric cool to room temperature before rinsing thoroughly in one or two changes of room temperature 75E to 95EF (24E to 35EC) water.

8. Remove excess water and dry.
