| Résumé : |
In order to ameliorate technological problems such as the pollution due to leather tannage and the long process time, a vacuum mechanism has been developed and is proposed as a tanning method. This article describes the mechanism and characteristics of vacuum tannage and analyzes the major factors affecting the course of vacuum tannage. The results show that, on the premise of increasing the overall quality of leather tannage, the working time is greatly shortened and the discharge of waste liquid is decreased by more than 50 %. |
