Metal-free leather tanned with oxazolidine
The present invention relates to those cases where leather tanneries or leather processing industries need to meet the market demand for the production of metal-free leathers, thus avoiding the use of traditional mineral tanning agents (trivalent chromium basic salts).
This patent describes a tanning process for obtaining metal-free leathers that maintain their appearance, qualities and physical-chemical properties, which make them suitable for use in manufacture and commercialisation of different leather products: footwear, leather goods, clothing, upholstery, etc.
This technology is patent protected.
