Bioleather or bio-based leather is a term used to describe a biobased material intentionally made from substances derived from once-living organisms. These are also called biomaterials. Such materials can be grown, for example, with the microorganism, sugar (such as green tea, sugar, and yeasts) or from natural fibre and oils. Flax fibre or cotton fibre and plant oils are laminated together in layers to create a breathable, leather-like material.
When manufacturing with microbes the sugar serves as the bacteria’s food source which makes threads of cellulose, as it grows the threads stick jointly forming a skin-like material. After about three weeks, this skin will be as thick as 1.5 centimetres. Then when the material is wet, it can be formed 3D on a moulded shape or flattened out as a regular fabric to be cut and sewn. This process is actually how Suzanne Lee is working making the BioCouture collection. Before it can be used as a leather further coating is needed with for example Paraffin.
