Acid dyeing handspun remainders

A recent stock-take of the various bits of hand-spun yarn sitting on bobbins I now want to use for other projects inspired me to ply them all up and dye them into interesting yarns. Only small quantites of most, but great for small items.

One was a test of blending Tussah silk with Lleyn fleece, and I plied this with some nice soft spun Dorset singles. The silk added a pleasant dry handle to the plied yarn, and the noils added texture. There was more Dorset singles left, so I plied these together as a separate yarns. Next I plied two ends of Suffolk together, they were somewhat different thicknesses and twists, so made a slightly uneven, spiralled yarn. Finally I worked with a lovely colour changing singles, spun from a blend of Alpaca and Texel (cream) and Black Alpaca and Dark Grey (almost black) Suffolk fleece. The Alpaca blends had been carded in stripes on the drum carder so that when it was spun off the batt it alternated in dark and then light lengths. I plied this with a pale grey Suffolk single that I had acquired from a farm in Hereford last summer.

All these came out as interesting yarns in their own right, but I wanted to add some COLOUR. So I got out the dye kettle and the acid dyes. After some thought I decided to aim for a Deep Red and a Blue-Violet. I’ve been trying to be more technical about my dye mixing, and so with the aid of an Excel spreadsheet I have devised, I carefully mixed the solutions, but the Blue-Violet still emerged as Violet.

There was 66g of the Dorset and Suffolk/Dorset, and they went into the Red dyebath, whilst the 45g of Lleyn/Tussah/Dorset went into the Blue-Violet bath and they gently cooked away for an hour or so.

Part of my improved technique is to use a jam thermometer to keep the bath below 90C, preferably just above 89C to prevent felting. I also walk away so I am not tempted to STIR IT! The only stir I am allowed is after teh bath gets to temperature, when I gently remove the yarns, add the vinegar and stir it in. I read that doing this allows the different colours in the mix to be absorbed into the yarn (or fibre), before the acid does its work to set the dye to the fibres. Both these techniques seem to work well for me as I am getting less felting and more even, accurate colours (apart from the Blue Violet of course).

The dye baths were not exhausted – I had worked with a 2% colour to fibre weight ratio for medium depth of colour – so the lovely tweed ply was dip dyed into both pots, leaving mid-sections of the natural tweed plies undyed. I felt this needed a third colour to lift the others, so a very small section between each of the main colours was dipped into a weak yellow dye.

Dark red in front, dip dyed tweed in the middle, blue-violet at the back. You can just see the texural Tusssah silk blended purple yarn.

I’m really pleased with the products of the session – carried out whilst I watched the new TV programme ‘Roadkill’. Unfortunately I was a bit stupid, or maybe it was the effect of the programme I was watching, and whilst mixing a new batch of yellow stock solution I mindlessly poured boiling water onto the dye powder in a plastic jar. Of course the jar melted, buckled sideways and then toppled to the floor before I could catch it. Waves of strong yellow dye flooded the kitchen floor (I am exaggerating, it was only 150ml or so, it just felt like waves). It took five washes to clean the floor so that no-one would walk yellow onto the beige carpets, and my socks will never be the same again! Plus I had to start again with the stock solution. I did debate mopping the floor with some yarn, but decided that might be too hit-and-miss even for me…

In fact this morning, whilst hiding from the dog, (don’t ask why) I noticed a snail-trail of yellow dye snaking down the side of the kitchen cabinet – how did I miss that one?

What am I going to use the yarns for? I think a warm hat to cheer me up with its bright colours during this depressing winter-to-come is on the cards. I might knit it by hand or I maybe use my Brother KH260 chunky machine, and hope to report back on here when its finished.

Footnote:

Leaving the dye overnight in the pots – I was tired after all that floor-mpopping – the next morning I decided to finally extract the last from each one. So 50g of Dorset fleece went into each, and I got a rich coral pink, and surprisingly bright lilac for my troubles. It was so rewarding to empty clear water out of the dye baths afterwards.

Waste-not-want-not is a good motto.

    OMG, Vikki. This reminds me of the time tried my hand at soap making. We rendered the tallow and then I poured it into a plastic bowl- hot grease in a plastic bowl. Don’t know what I was thinking. If you think dye is hard to mop up, you should try rendered beef fat. My home smelled like french fries for a looooong time.
