I recognised that many of the samples from SADACC had been dyed using natural dyes, this is one of my main interests overall in textiles and I thought I could incorporate this in my work for Project 2. My knowledge on natural dye isn't brilliant so doing some research will really help me in achieving naturally dyed fabrics.

*must buy Jenny Dean's 'Colours from Nature' book*- in the NUA library as well as 'Wild Colour'*
I want to further research if it is possible to print with natural dyes using a screen.
-is there a way of adding a paste to the dye to thicken?- UPDATE http://krex.k-state.edu/dspace/handle/2097/3899- Thickening madder???
-how does it apply if so?
-will the colour stay?
-how much hassle involved?
-is it more time consuming?

Substantive dyes are used by combining the dyestuff, normally the amount equal to or twice the amount of the weight of the fibre. Then it must be strained then simmered for a while. For example turmeric (working on cotton as well as wool), onion skins, walnut husks, and tea.
Vat Dyes
The vat dyes work the same way on protein and cellulose, by being introduced into the surface of the fibre while in soluble form and then converted into an insoluble form. The vat dyes include many synthetic dyes, but also the natural dye indigo, and the ancient Tyrian Purple dye taken from shellfish. They are complicated to use, needing the establishment of an oxygen-free fermentation.
Mordant Dyes
Most natural dyeing is done with the use of mordants, most commonly heavy metal ions, but sometimes tannins. Tannins are important in dyeing cotton and other cellulose fibres. The mordant allows many natural dyes which would just wash. A mordant remains in the fibre permanently, holding in the dye. Each different metal (used as a mordant) produces a different range of colors for each dye.
