dyeing scrim – one of many ways to do so

8 07 2012

This post will show you how easy it is to dye a range of colours.  This is a very simple process but worth revisiting from time to time.

From this:

To this:

I cut the scrim into five metre lengths.  There will be some shrinkage so I should get at least 4.5mtrs of useable fabric.  Each colourway has five colours, so 25 mtrs in total per colourway.  Obviously that is not a rule and you can work on a larger or smaller scale.

I pre-soak my fabrics in a soda ash solution.  Soda ash, or sodium carbonate is the mordant for the reactive dyes.  In this process, I am doing 15 colourways of 25 mtrs each, so I put about three cups of soda ash into about 30 litres of water and that will last me through the whole process plus some.  I soak the fabric for at least half an hour and wring it out, reserving the soda ash solution.  Then, each 5 mtr length goes into its own bucket.

I have a fabulous outdoor area that is covered in where I do all my dyeing and other wet processes.

My starting point for my dyes is a teaspoon per litre of water.  While your fabric is soaking in the mordant, mix your dyes.  The Procion MX dyes are a cold water dye, but I tend to use hot tap water to speed up the dissolving, especially when it is the middle of a Canberra winter and struggled to get into double figures temperature wise.

Give the dyes a good stir to make sure the dye powder is fully dissolved.  Then pour the dye over each piece of fabric – one colour per bucket.

This is my Winter colourway.  It is soft and frosty.  Leave the dye on the fabric for at least three to four hours and then rinse until the water runs clear.

Ready to use.

Thank you for the diagrams. When you say “put about three cups of soda ash into about 30 litres of dye and that will last me through the whole process plus some.” do you mean 30 litres of water?

yes, well picked up. I do mean water, not dye.
