====== BioFabricating Dyes & Materials ======

17-10-2017

Cecilia Raspanti

The textile industry is one of the most polluting in the world, in which one the most environmentally disastrous processes is the dyeing of fibers and textiles of the clothes we wear. Chemicals are released daily in rivers and nature destroying the environment around us to satisfy the colour demands that we create as designers, industry and consumers. Very few options are being explored in this fast changing fashion, clothing and textile industry, and the list of chemical treatments is only expanding.

This class will focus on exploring material and colouring alternatives to the current ones. Ranging from natural dyes, using pigments and bacteria, to material biofabrication. Local recipes of DIY materials

  *

bio -plastics -resins -silicones

  * gelatine
  * starch
  * glycerine
  * water
  * vinegar
  * pigments

**Assignment**

The students can work in group, identifying tasks and splitting them, as long as they all proof they are able to carry out each task.

Explore at least:

•**1 natural dye or bacterial dye**

**•1 crafted or grown material**

Dont just reproduce, mix, match, change amounts or patterns and compare.

**Order, display, map / compare and credit, for the process and the results:** \\ • **Ordering**  – organised material is knowledge. Name your materials, classify them by typology. \\ • **Displaying**  – display them in a way that makes sense. Badly displayed materials, loose all their beauty. \\ • **Mapping**  is essential for comparing results. Change small elements in a recipe and compare the results. \\ • **Credit**  your recipes and changes
