Abstract: The purpose of this study is to replace chrome tannins with ecofriendly vegetable tannins as an alternative solution to prevent the public health and the environmental pollution. Vegetable tannin was extracted from Cassia singueana bark using an aqueous extraction method and applied on sheep pickle pelt. Optimum tannin extraction parameters were identified at powder concentration of 80 g/L, extraction temperature of 100°C, and extraction time of 120 mins. Chemical functionality of Cassia singueana extracted ta… Show more

“…Ecological leather manufacturing development will thus become the trend of the times . At present, chrome-free tanning agents mainly include two categories, i.e., chrome-free metal tanning agents and organic tanning agents, in which tannin extract is the most commonly used. Meanwhile, there are also some synthetic tanning agents in the organic category, such as TWS, F-90, aromatic synthetic tanning agent, amino resin tanning agent, acrylic resin tanning agent, epoxy compound tanning agent, etc., which are mainly combined with the active groups on leather collagen by covalent, ionic, or hydrogen bonds to achieve the tanning effect through their aldehyde, amino, carboxyl, and other functional groups.…”
