bio-couture :: green tea leather
The process uses a sugary green tea recipe, to which, a bacterial culture is added. It takes about 2-4 weeks to grow a sheet that is thick enough to use. Sheets are then dried down; either shaped over a wooden dress form–like the ghost dress and ruff jacket –or sewn together conventionally. Depending on the recipe the material can either feel like paper or–more desirably–like a vegetable leather.
In testing with dyes we found no need for mordant [a substance used for dyeing fabrics] and an incredibly small amount of dye goes a long way so it’s eco-credentials go through the entire process. We also recycle a percentage of the fermentation liquid.
We look forward to more information about the project and the process. Read more about it at treehugger.
Thanks Rob for pointing this out :)
