Ecological Textiles offers a range of thirteen semi translucent woolen fabrics, dyed with natural colours. All of the colours have been derived from three plants: madder (Rubia Tinctorium), woad (Isatis Tinctoria) and weld (Reseda Luteola). Dyeing with plants not only stands in a long and beautiful tradition, naturally dyed fabrics also show a rich, broad colour spectrum as a result of the different colouring particles in the plant, where in chemical dyes only one molecule determines a colour. Apart from this natural dyes are produced from renewable sources (plants), whereas synthetic dyes still use fossil oil.
