Acid Dying

I love colour! So I spent a few days making my own!

Acid dyes provide a simple system for use with wool, other animal fibres including fur, feathers, cashmere and angora as well as most nylons. The dyes themselves are not acidic, the word acid merely referring to the vinegar (acetic acid) which is used to help set them.

The quantity of dye used depends on the depth of colour you want. It is measured in relation to weight of fibre or yarn to be dyed. Using the 1% stock solution, a 2:1 ratio (50cc of 1% dye solution for 25g fibre) will give an average depth of colour. This is just a starting point to experiment from. Deep colours will need much more, while you can get lovely pale colours with far less. Use vinegar or citric acid to set these dyes. 50g dye powder will dye up to 5kg depending on the intensity of colour required. – ( 

I wanted to try out a mixture of thicker yarns and my normal 2/17’s un-dyed lambswool. (All the wool used is UK based and 100% Lambswool)  


Whilst at University I dyed an acid green/yellow that I became slightly obsessed with, and have almost finished the cone, so to start off the dying I had to try and recreate it.


Acid dying is a bit of trial and error. You simply just have to keep adding your dye bit by bit to your vat until you achieve a colour your happy with! I used small strands to test each colour, and these can then go into my technical file to show the different levels you can achieve.

Next on my list were oranges, browns, greys and Blues.


I could have gone on and on dying with the blues, there are so many endless beautiful alternatives.


And on to the brightest of them all! PINK! yellows and more orange. Again at university I used this hot pink a a lot in one of my collections, and I’ve now finished the whole cone so wanted to recreate it! I love the intensity of colour you can achieve with acid dyes, they’re so striking and vibrant side by side!


Finally all my colours as hanks! This is such a simple and easy method of dying, and each colour is easy to recreate! I recommend having a go!
