| Résumé : |
Milling is a key process to soften leather for adequate compliance. It is, however, still not well understood for its effects on leather structure and mechanical properties. To consistently produce high quality leather, it is essential that the tanner understands the impact and effects of every mechanical operation in the leather-making process. This investigation is devoted to gaining a better understanding of milling effects on pliability and other properties of concern to the leather industry, such as mechanical strength and toughness. Observation showed milling leads to a decrease in Young’s modulus, consequently an improved compliance and softness. Data also showed, however, there is little change in tensile strength and toughness. Moreover, leather products in service are constantly being stretched. For understanding the mechanical behavior of leather products under cyclic stretching, we measured the energy loss (hysteresis) during cyclic tensile tests using an advanced computing program. Data showed that hysteresis is the greatest for the first cycle, thereafter, the rest of hysteresis values are relatively unchanged. We also discovered that drum milling significantly decreases the hysteresis. This implies that a structural change occurs during milling, resulting in a removal of the residual stress that was introduced during the leather making process. |
