Tufts University steps towards sustainability in leather by using silk

Fibre2Fashion Toggle navigation 11 Pic: Tufts University Scientists at the Tufts University School of Engineering have created leather-like material from silk. The team broke down the fibres from silkworm cocoons into their proteins, and used these proteins to form the leather-like material. This leather can be printed into different patterns and textures, and has similar physical properties as real leather. The aim was to find an alternative to leather, with similar texture, flexibility and stiffness, but using materials that are sustainable, non-toxic, and friendly to the environment. Instead of weaving the silk into fabric, the Tufts engineers were able to break down the fibres from silkworm cocoons into their protein components, and re-purpose the proteins to form the leather-like material. The process for making silk-based leather is described in a study published in the journal Materials & Design.
