CHARACTERIZATION OF THE EFFECT OF HEAT ON VEGETABLE TANNED LEATHER

International audienceFunded by the LabEx PATRIMA, this project combines the expertise of the CRCC laboratory, in physical chemistry and the ERRMECe laboratory in biology and biochemistry. The research aims to develop a new restoration approach for leather having lost its flexibility as a result of alteration, in particular after exposure to heat. This innovative method relies on the use of biological molecules to respect the nature of the object and preserve its past and future.Our hypothesis is that exposure to heat causes a protein aggregation. To validate this hypothesis and develop the restoration method, the modifications taking place in the leather structure are examined at different scales
