Evaluation of (Re)tanning Effect of Leather Chemicals in a Model and a Real System
Smit & Zoon is continuously researching sustainable alternatives to leather testing, for the development of new products. Our scientists examine the use of a model to test new products, in order to save large amounts of leather and avoid the disadvantages of inevitable variations and non-standardised wet-end recipes encountered in regular testing on real leather. You can read more about our ongoing research into sustainable alternatives in our published whitepaper.Download the whitepaper here
The SmiTool Light and Heat already discussed the subject of heat yellowing and light fastness tests on leather. The current SmiTool explains the differences between subjective and objective assessments of tested leather and how to report test results for heat yellowing and light fastness.
Making leather is no longer the art it once was. Leather makers now have to comply with such a vast amount of legislation and other regulations that the actual process of producing leather has been effectively sidelined.
