Pre-Treating Fiber before Dyeing


Step One: Scour Bath


Cellulose Fiber Scouring Bath (for Cotton & Linen):

Soda Ash - For every 3.5oz of fiber, use .5oz of Soda Ash

Mix your soda ash to a small bowl of warm water, allowing it to dissolve, then add to a stainless steel pot filled with enough water to let your fiber float around freely in the pot. Bring the temp to a low simmer and hold there for about half hour.

Take pot off the stove and let it cool to room temperature, then remove your fiber and rinse with cool water.

-OR-

Protein Fiber Scouring Bath (for Silk & Wool):

As a general rule, for every 17.6oz of fiber you add .5 teaspoons of Synthrapol detergent. I didn’t want to purchase special detergent since I am just experimenting still…so, I just used a few drops of Dr. Bronners and it seems to work fine.

Mix your synthrapol or few drops of Dr. Bronners to a small bowl of warm water, allowing it to dissolve, then add to a stainless steel pot filled with enough water to let your fiber float around freely in the pot. Bring the temp to a low simmer and hold there for about half hour.

Take pot off the stove and let it cool to room temperature, then remove your fiber and rinse with warm water.



Step Two: Mordant Bath


Cellulose Fiber Mordant Bath (for Cotton & Linen):

For cellulose fibers, you will use Alum Acetate - For every 3.5oz of fiber add .4oz of alum acetate.

Mix your alum acetate to a small bowl of warm water, allowing it to dissolve, then add to a stainless steel pot filled with enough water to let your fiber float around freely in the pot. Bring the temp to a low simmer and hold there for about half hour.

Take pot off the stove and let it cool to room temperature. Cellulose mordant baths work best if you allow the fiber to soak in the bath for at LEAST 2 hours, and up to 24 hours.


-OR-

Protein Fiber Mordant Bath (for Silk & Wool):

For protein fibers, you will use Alum Potassium Sulfate as a mordant - for every 3.5oz of fiber add .3oz of alum potassium sulfate.

Mix your alum potassium sulfate to a small bowl of warm water, allowing it to dissolve, then add to a stainless steel pot filled with enough water to let your fiber float around freely in the pot. Bring the temp to a low simmer and hold there for about 1 hour.

Take pot off the stove and let it cool to room temperature, then remove your fiber and rinse with cool water.
