| titleOfInvention | Environment-friendly type crust leather production method |
| abstract | The invention discloses an environment-friendly type crust leather production method, and aims at solving the problems that in a crust leather production method using conventional chrome tanning as basis, plenty of chromium ions are contained in waste water and cannot be effectively processed, plenty of leather wastes with chrome are also generated, and the environment is seriously polluted. The production method comprises the following steps of non-pickling tanning, retanning filling, dyeing fat liquoring and chrome retanning. The method adopts non-pickling non-chrome tanning technology, so solid wastes with the chrome cannot be generated. At the same time, through mutual matching with other procedures, finished leather shrinkage temperature and performance can be effectively improved so as to meet demands of leather production. At the last, the chrome retanning is adopted, only a path of waste water with the chrome is generated, waste water quantity is small, and the waste water is easy to recover and process. Therefore, compared with an existing crust leather production method using a chrome tanning method as basis, cleaning degree is high, the waste water quantity with the chrome can be effectively reduced, and the waste water is convenient to recover and process. At the same time, the leather wastes with the chrome cannot be produced, and the method is environment-friendly. |
