Evaluation of (re)tanning effect of leather chemicals in a model and a real system

摘要

In the large portfolio of retanning chemicals, it is important to distinguish between the effect of different chemicals on leather in order to effectively develop new products that can deliver differentiated functionalities. However, the traditional route for such a process is very tedious and costly due to the fact that: 1. Tests need to be done on leather, which is a natural material that presents inevitable variations making comparison tests rather difficult to reproduce; 2. Reliable results require large amount of starting material (leather) and work since full wet-end recipes need to be applied for each set of tests; 3. Wet-end leather application recipes are rarely standardised in a simplified manner to ensure that the obtained results will have a real predictive character.
