Fatliquors for leather makingFatliquors are a type of chemicals used in the leather manufacturing process to add softness, flexibility, and durability to leather. They are typically added after the leather has been tanned and dried, but before it is finished. Whitepaper: ecoSimplicityecoSimplicity is your helping hand to boost the efficiency of post-tanning operations and to enable an environmentally friendly leather production at the same time. Phenolic monomers in aromatic syntans: the influence on leatherAromatic syntans are widely used in the (re)tanning of leathers. Phenolic monomers such as phenol, phenolsulfonic acid, bisphenol S, and bisphenol F are common compounds in aromatic syntans. Stay informed. Subscribe to our newsletterSubscribe Whitepaper Color Analysis on LeatherThe 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. Biopol collectionThe Smit & Zoon company developed new range of Biopol products. These are based on the concept of the circular economy. Circular economy focuses on the utilization of renewable sources, waste streams reutilization or smart utilization of low(no)-value biomass side-streams minimizing product environmental footprint.
