Abstract The fragility and weakness of historical, archaeological, and heritage leather artifacts in museums, and libraries due to unsuitable environmental conditions are significant challenges. This study aims to assess the effectiveness of Hydroxypropyl Beta Cyclodextrin, a novel material, in consolidating leather artifacts by examining their physical, chemical, and mechanical properties. Vegetable-tanned leather samples were treated with different concentrations of Hydroxypropyl Beta Cyclodextrin and subjected to artificial heat aging. Evaluation methods included digital and scanning electron microscopy, contact angle measurements, mechanical testing, color analysis, pH measurement, and Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy. Results showed that Hydroxypropyl Beta Cyclodextrin at 1% and 2% concentrations improved chemical stability, surface morphology, color retention, and mechanical properties of the leather samples. The third concentration yielded less favorable outcomes. This study recommends using Hydroxypropyl Beta Cyclodextrin at 1% and 2% concentrations for consolidating historical leathers. |
