The Dyeing Process!!! How to Dye Wool.

I ordered a few dyes from KraftKolour (click here to view website). The dyes from KraftKolour 

How to - Dye Wool Fibres (fabric, yarn, fleece etc) using Acid Milling Dyes
Formulas for dyeing can fluctuate depending on the depth of colour you desire and the thickness, weight and type of material you use. Some formulas can also be very confusing. It is always wise to do a few sample pieces first. Always use caution and safety gear. It is advised that you use instructions from your supplier and then vary.

This is the instructions on how I dyed a hand knitted neck piece with Acid Milling Dye - it will be worn as part of my collection for Perth Fashion Festival.

What you will need - a big pot, a stirring spoon, acid milling dye (in the colour of your choice), household vinegar, salt, water and a stove or hotplate (plus any safety gear- gloves, mask etc).

1. Wet your material thoroughly.
2. Place 1lt of water in large pot on low heat. (use enough water so that your material is completely immersed)
3. Add Dye (I used about two teaspoons mixed in about 100ml of water) and pre-wetted material.
4. Stir continuously.
5. Gradually heat (this may take around 20mins). Make sure you only simmer, don't boil.
6. Remove fabric from dye bath.
7. Add vinegar (50ml dissolved in 100mls water) and stir
[It is important to note - that you always add acid to water and never water to acid, otherwise a violent reaction may occur.]
8. Add salt (I use about 2-4 tablespoons dissolved in 100mls water) and stir
9. Replace material and continue to stir.
10. Simmer until dye bath is exhausted. (you will know when it is exhausted because the water will be clear)
11. Rinse well and dry.

And you are done!!!
