BioChromes

October 8th, 2024

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 colouring alternatives to the current ones. Bridging craftsmanship techniques and technology, to explore alternative colour sources and their processing. Ranging from plant based, insect base and bacteria based pigments.
