Breakdown




I didn't think I would like this technique all that much, but it was awesome and everyone had a ball.
Breakdown Printing

Materials:
Blank silk screen
Squeege
Thickened dye
Made with Sodium Alginate and dye powder
Fabric Silk for Acid Dye Cotton for Procion Dye

Pre-preparation:
Mix Sodium Alginate
Into a quart of warm water stir 1 to 2 Tablespoons of Sodium Alginate powder.
Stir until dissolved or use a dedicated blender to mix (It will still have a few lumps)
Let it sit for at least 1 to 2 hours or overnight. If it is too thick stir in warm water to thin the solution. If not using right away refrigerate until ready to use.

Soak Cotton, Linen, or Rayon
Make a Soda Ash solution of 1/2 cup Soda Ash with 1 gallon water and soak the fabric at least 15 to 30 minutes. Hang to dry, press lightly with warm iron.

Silk Printing:
Mix Acid dye powder with thickened Sodium Alginate (1 or 2 teaspoons dye powder per 1 Cup thickener). Mix well the day before using. Refrigerate until ready to use.

Prepare the Screen:
Lightly coat inside of the screen with a couple of colors of thickened dye, leaving some open spaces. Let it dry upside down. This needs to be done far enough in advance to be completely dry before printing.

Printing:
Iron the silk fabric smooth and place on a padded surface. Lay the prepared screen down and use another color thickened dye or clear thickener or more than one color thickened dye and squeegee it across the dry dye. As you print the dried dye will breakdown and each print will be different. This is the magic of this technique.

Setting the Dye: The silk will need to be steam set. Then rinsed to remove the thickener and any excess dye. Damp dry and iron until dry.

Cotton, Linen, or Rayon Printing:
Mix Procion Dye powder with thickened Sodium Alginate ( 1 or 2 teaspoons dye powder per 1 Cup thickener). Mix well the day before using. Refrigerate until ready to use.

Prepare the Screen as above and let it dry upside down.

Printing: Lay out the smoothed Soda Ash treated fabric on a padded surface and print as above; however while the print is still wet cover with plastic and roll the fabric and plastic up and place in a plastic bag for 24 hours to “batch” and set the dye. After 24 hours rinse and rinse again then dry until just damp and iron dry.
