| Résumé : |
The application of leather dressing and lubricants is one of the important challenges in conservation of historic dry leathers, due to their effects on structural and visual properties and stability of leathers. This study aimed to investigate influence and stability of silicone oil and polyethylene glycol (PEG) on treated dry leathers, and application assessment of ascorbic acid (AA) as an antioxidant additive for PEG. The polymers, untreated and treated leather samples were submitted to heat accelerated ageing process. FTIR spectroscopy, colorimetry, pH measurements, investigation of mechanical properties and shrinkage temperature (Ts) were used to explain effect of treatments. Also, the oxidation of polymers during ageing process was monitored by FTIR spectroscopy. Results showed that silicone oil has better stability against thermal oxidation with compared to PEG. Ascorbic acid inhibited the PEG oxidation. Moreover, results revealed that the silicone oil has a better performance in treatment of dry leather than PEG or PEG+AA, due to its high stability and minimum changes in visual, structural and mechanical properties in treated leathers. |
