This uniquely dyed fabric is part of an on-going research project that aims to develop sustainable textile dyes, and builds upon the age old practice of using natural plant materials to dye fabrics. Here, however, in this 21st century craft, the sources of the natural pigments are invisible pigment factories, in the form of billions of microscopic cells of bacteria which naturally produce the coloured pigments that can be seen on the textile. I hope to turn the fabric into a Summer Frock that could be worn by a model on a catwalk, as having been autoclaved and survived the process, the material is free of living bacteria and thus safe to handle. In future projects, I am hoping to replace the unsustainable process of indigo production, for the dyeing of, denim with sustainable pigments of bacterial origin.
