| Résumé : |
The environmental and health concerns over the use and disposal of chrome-tanned leather have encouraged the use of non-chrome-tanned (chrome-free) leather. The drying operation is a critical leather-making step to attainthe required physical properties for leather products. We recently conducted a drying study on non-chrome-tanned leather made with a glutaraldehyde-tanning process. Results showed that the physical properties of leather, such as area retention and softness, were affected significantly by the drying method. Data revealed that leather with inferior fracture energy often resulted in poor grainbreak. In addition, observations showed that drying methods using toggling produced higher areayield; however, it resulted in stiffer leather. Our research showed that residual water content plays an important role in controlling the softness of leather. Vacuum drying without toggling yields better toughness and softness. A dimensionless quantity "toughness index" showed a strong correlation with the resultant area retention, which agrees with our previous findings for chrome-tanned leather. |
