| Résumé : |
Due to its fast drying speed, vacuum drying has become one of the most popular drying methods in recent years for leather manufacture. However, information regarding how drying conditions affect the resulting leather mechanical properties is lacking. Without this information, drying operations often produce leather with poor mechanical properties. Therefore, we conducted a systematic vacuum drying study to gain a clear picture of how drying variables affect the mechanical properties of vacuum-dried leather. Data clearly indicate that a lower drying temperature, shorter drying time, and proper initial water content in leather are favorable conditions to produce stronger and softer leather. In this investigation we not only formulate the relationship between drying factors and mechanical properties, but also explore the possibility using a mass transfer quantity such as drying rate to generalize the complex relationship between drying variables and resultant mechanical properties. Observations showed that the rate of drying is one of key factors that governs the tear strength. This investigation may benefit the leather industry in optimizing drying conditions to obtain improved mechanical properties. |
