How to give leather a high level of elasticity while preserving its appearance?

Henri GUENOUN based himself on the layered structure of leather. As this material can be separated into several layers, he developed a process that, by assembling the leather sub-layers at a very high temperature (120°C) with a material whose elasticity is lower than leathers stretch and failure limit, provides a leather with high elasticity properties.

By filing patents in France (n° 9200379) and in Europe (n° 730665), Henri Guenoun ensured that only the French J.M. Marthens company would be able to use this patent.
