Chemical solutions company Archroma has partnered with Trumpler (which specializes in leather chemicals) on a new eco-friendly process to produce high-performance leather. The new process, called DyTan, combines innovations from the two companies to offer an alternative to existing metal-free and chrome-tanned leather. DyTan is free from metal salts and reactive aldehydes and is suitable for a wide range of leather applications, from garment and footwear to automotive and furniture upholstery, according to Archroma.
The DyTan process uses Archroma’s patented Avicuero System, which is based on novel molecules that enable more sustainable leather tanning and dyeing, according to Archroma. The Avicuero System, developed by Archroma in cooperation with leather technology consultant Dr Leather, enables collagen fibers in the leather to be covalently cross-linked through a simplified process at low temperatures. This system reduces process time and CO2 emissions by up to 23 percent while also showing strong potential to save energy and water. The DyTan process combines the Avicuero System with Trumpler’s bio-based fat liquors and retanning agents based on functional biopolymers produced from hydrolyzed shavings.
The Trumpler Group is an exclusive global partner of Archroma and is responsible for the distribution of the Avicuero System worldwide.
