Dyeing silk with blackberry
Last week I dyed a fabric using blackberries picked in the woods near my house.
The image below is the fabrics I dyed with blackberry and a synthetic dye. I made strips with all of those purple fabrics and wove a little purse (the image above).
<How I dyed silk with blackberry (natural dye)>
- 4/5 cup of blackberry juice (I removed seeds with a strainer).
- 50 grams of silk
- a pot
A mordant helps dyeing solidify. I used mordant to dye the right hand silk above, which is darker than the other silk.
- a table spoon of potassium aluminum sulfate, to be dissolved into a half liter of water.
- a bowl: silk will be soaked in the alum solution in this bowl
*If you do not use mordant, skip 5 and 6.
- Make an alum solution: dissolve a table spoon of potassium aluminum sulfate in a half litler of hot water. Let it get cooled down.
- Soak the silk in warm water because prewetting fabric helps a dye spreads faster and more uniformly.
- Warm up 1 liter of water in a pot, put 4/5 cup of blackberry juice and shake well.
- Put the prewetting silk in 3. and boil it for 15 minutes. Stir many times so that the silk is uniformly dyed.
- Remove the silk from the pot, and rinse in fresh water. Then, soak the silk in the alum water, and leave it for 5 minutes.
- Pick up the silk from the alum water and rinse in fresh water. Put the silk back to the pot, and boil it again for 15 minutes.
- Turn off the fire and leave the silk until it gets cooled down.
- Remove the silk from the pot, wash, spin in a wishing machine and hang it to get dry.
This was my first time to dye silk with blackberry and I do not know how the purple color will change over time. I will watch out and let you know how the purple will stay or wear out.
