Week 1: June 1st - 7th
Dye Process: Preparing
Sunday I participated in a beach cleanup organized by Living Oceans and my host, Kerri, then started preparing my dye baths and fabric. This process is time consuming, and I'm not even taking the amount of time I could to prepare my fabric with mordants such as soy milk (which is a multi-day process in itself). It will take me about 4 days before I'm ready to even start dyeing my fabric or thread. I brought with me many different types of materials to dye in many different ways. I'm curious to try eco-dyeing bundles, solar dyeing, and more traditional dyeing processes.
I brought three different kinds of thread to try embroidering with: 100% silk, 50/50 silk/merino wool blend, and a silk/linen blend. They're from the Silk Weaving Studio on Granville Island and I decided on silk blends because they're protein-based and will pick up dye colours more vividly than a cotton thread. I also have lots of cotton muslin, some wool jersey, vintage linen, and a handful of cotton baby onesies.
All these different materials need to be prepped in different ways and each round of scouring (cleaning) and mordanting (applying minerals to help the dye colour stick and become colour fast) takes about 2 hours. This is what I did to get ready to dye:
- The skeins of silk thread need to be divided into smaller skeins (10 m pieces)
- Any new fabric needs to be scoured to remove any sizing - cotton and wool need to be treated differently in this process
- Before dyeing, the material needs a mordant (especially the cotton and linen)
- Cellulose-based fibre like cotton and linen: Tannin and alum bath OR alum and washing soda (sodium carbonate)
- Protein-based fibre like silk or wool: Alum and cream of tartar
- Soak any dye plants overnight, then simmer for an hour to release the colour
A post-dye bath of iron can also be used alter the dye colour to shift the colour into grey. Once I've done all the dyeing, I can decide whether things need to be over-dyed (put in another dye pot to change the colour) or dipped into an iron bath. I've been focussing on dye stuff and mordants that can be safely discarded of. This means that I'm avoiding using a mordants like tin or copper. I'm also aware that iron is difficult to dispose of, so I will likely bring home the iron bath that I make so I can dispose of it properly.
