Low Carbon Products to Design Innovative Leather Processes. Part IV: Manufacture of Automotive Leather Using Tara

摘要

In three previous studies, it has been used the fruit of the tara tree (Caesalpinia Spinosa) as a pre-tanning agent(1). This new tailored tara product will be able to facilitate the penetration of the tannin molecules through the leather section, avoiding or reducing the use of aldehydes, syntans, common vegetable tannins and other mineral salts.
