Leather chemicals manufacturer TFL will deliver two presentations at the XXXV IULTCS Congress, Dresden from June 25-28. The company is a main sponsor of the event.
The two scientific papers are:
- Evaluating the performance limits of automotive leathers (Age flexing behavior) – The ageing performance of automotive leather coatings is complex to determine and TFL has taken a "full system approach" to determine how best to make high performance, long-lasting automotive leather coatings.
- Modern unhairing technologies for effective control of hydrogen sulphide release from beamhouse operations: The toxicity and unpleasant smell of hydrogen sulphide (H2S) gas is an issue for the leather industry that has been contained rather than eliminated in tannery practice. TFL shows how the release of hydrogen sulphide from beamhouse operations can be effectively controlled by a combination of technologies involving more effective unhairing with lower amounts of reductive agents, replacement of inorganic sulphide by organic thio compound and the use of H2S scavengers.
