The Travelcard holder's outer fabric is made from wood leather. This innovative material is made from thin sheets of real wood bonded to a fabric using an environmentally friendly adhesive. To make the material pliable, small micro laser etchings are applied, leaving a soft leather-like touch.
The wood leather reduces the kg CO2 emitted into the atmosphere by about 60% compared to a square meter of leather.
The lining is made from Cupro Satin - a “regenerated cellulose” fabric made from cotton waste. It is made using the silky cotton fibres, known as cotton linter, that stick out of the cotton seed and that are too small to spin. The linter is dissolved into a cuprammonium solution, which is a mixture of copper and ammonium, before being spun into fibre. Like Tencel and Modal, Cupro is a plant-based material that is chemically processed to produce the fabric.
